Patent Application
20170218312
The present application relates to compositions comprising an antifoam and methods of making and using such compositions.
Compositions such as cleaning and/or treatment compositions may employ materials that produce suds. In certain cleaning and/or treatment compositions, the level of suds is higher than desired. One manner of reducing suds is to add an antifoamer to the cleaning and/or treatment composition. Unfortunately, the stability, and thus the performance of antifoams may, over time, be compromised by other formulation ingredients.
Applicants recognized that the source of the stability problem was due to certain moieties that are found on certain formulation ingredients. Such formulation ingredients include certain perfumes and solvents. While not being bound by theory, Applicants believe that the problems associated with such formulation ingredients arise as such formulation ingredients penetrate the antifoam and thus separate key components of the antifoam from the antifoam composition. Applicants recognized that such separation could be mitigated by choosing antifoam components that have strong Van der Waals and/or hydrophobic interactions with each other. Such antifoams represent a small selection of the overall antifoam possibilities and such antifoams are provided herein.
The present application relates to compositions such as cleaning and treatment compositions comprising an antifoam and methods of making and using such compositions. Such compositions comprise benefit agents that typically impact the performance of antifoams, yet in the present compositions, antifoaming properties of antifoams are maintained.
As used herein, the term “cleaning and/or treatment composition” includes, unless otherwise indicated, unit dose, granular or powder-form all-purpose or “heavy-duty” washing agents, especially cleaning detergents; liquid, gel or paste-form all-purpose washing agents, especially the so-called heavy-duty liquid types; liquid fine-fabric detergents; hand dishwashing agents or light duty dishwashing agents, especially those of the high-foaming type; machine dishwashing agents, including the various tablet, granular, liquid and rinse-aid types for household and institutional use; liquid cleaning and disinfecting agents, including antibacterial hand-wash types, cleaning bars; as well as cleaning auxiliaries such as bleach additives and “stain-stick” or pre-treat types, substrate-laden products such as dryer added sheets, dry and wetted wipes and pads, nonwoven substrates, and sponges; as well as sprays and mists.
As used herein, the term “fabric care composition” includes, unless otherwise indicated, fabric softening compositions, fabric enhancing compositions, fabric freshening compositions and combinations thereof.
As used herein, the articles “a” and “an” when used in a claim, are understood to mean one or more of what is claimed or described.
As used herein, the terms “include”, “includes” and “including” are meant to be synonymous with the phrase “including but not limited to”.
As used herein, the term “situs” includes paper products, fabrics, garments, hard surfaces, hair and skin.
As used to describe and/or recite the organomodified silicone element of the antifoams and cleaning and treatment compositions same herein, a 2-phenylpropylmethyl moiety is synonymous with: (methyl)(2-phenylpropyl); (2-Phenylpropyl)methyl; methyl(2-phenylpropyl); methyl(β-methylphenethyl); 2-phenylpropylmethyl; 2-phenylpropylMethyl; methyl 2-phenylpropyl; and Me 2-phenylpropyl. Thus, organomodified silicones can, by way of example, use nomenclature as follows:
As used herein, the term uninterrupted means the chain only comprises methylene groups.
As used herein, the term heteroatom takes it ordinary, customary meaning and thus includes N, O, S, P, Cl, Br, and I.
Unless otherwise noted, all component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.
It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

The cleaning compositions may contain from about 5% to about 90%, and in some examples, from about 10% to about 50%, by weight of the composition, of such carriers. For compact or super-compact heavy duty liquid or other forms of cleaning compositions, the use of water may be lower than about 40% by weight of the composition, or lower than about 20%, or lower than about 5%, or less than about 4% free water, or less than about 3% free water, or less than about 2% free water, or substantially free of free water (i.e., anhydrous).
For powder or bar cleaning compositions, or forms that include a solid or powder component (such as powder-containing unit dose cleaning composition), suitable fillers may include, but are not limited to, sodium sulfate, sodium chloride, clay, or other inert solid ingredients. Fillers may also include biomass or decolorized biomass. Fillers in granular, bar, or other solid cleaning compositions may comprise less than about 80% by weight of the cleaning composition, and in some examples, less than about 50% by weight of the cleaning composition. Compact or supercompact powder or solid cleaning compositions may comprise less than about 40% filler by weight of the cleaning composition, or less than about 20%, or less than about 10%.
For either compacted or supercompacted liquid or powder cleaning compositions, or other forms, the level of liquid or solid filler in the product may be reduced, such that either the same amount of active chemistry is delivered to the wash liquor as compared to noncompacted cleaning compositions, or in some examples, the cleaning composition is more efficient such that less active chemistry is delivered to the wash liquor as compared to noncompacted compositions. For example, the wash liquor may be formed by contacting the cleaning composition to water in such an amount so that the concentration of cleaning composition in the wash liquor is from above 0 g/l to 6 g/l. In some examples, the concentration may be from about 0.5 g/l to about 5 g/1, or to about 3.0 g/l, or to about 2.5 g/l, or to about 2.0 g/l, or to about 1.5 g/l, or from about 0 g/l to about 1.0 g/l, or from about 0 g/l to about 0.5 g/l. These dosages are not intended to be limiting, and other dosages may be used that will be apparent to those of ordinary skill in the art.
Buffer System
The cleaning compositions described herein may be formulated such that, during use in aqueous cleaning operations, the wash water will have a pH of between about 7.0 and about 12, and in some examples, between about 7.0 and about 11. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, or acids, and are well known to those skilled in the art. These include, but are not limited to, the use of sodium carbonate, citric acid or sodium citrate, lactic acid or lactate, monoethanol amine or other amines, boric acid or borates, and other pH-adjusting compounds well known in the art.

Such cleaning compositions may use wax-covered citric acid particles in conjunction with other pH control agents such that (i) about 3 minutes after contact with water, the pH of the wash liquor is greater than 10; (ii) about 10 minutes after contact with water, the pH of the wash liquor is less than 9.5; (iii) about 20 minutes after contact with water, the pH of the wash liquor is less than 9.0; and (iv) optionally, wherein, the equilibrium pH of the wash liquor is in the range of from about 7.0 to about 8.5.
UV Absorbers—in certain consumer product embodiments of the present invention, the photo-responsive encapsulates of the present invention may be stabilized against premature release by exposure to light of a sufficient wavelength during storage by incorporation of a suitable UV-absorbing ingredients into the composition. Any suitable UV-absorbing composition may be employed, but particularly preferred are those which do not impart an unpleasant color or odor to the composition, and which do not adversely affect the rheology of the product. Non-limiting examples of UV-absorbing ingredients include avobenzone, cinoxate, ecamsule, menthyl anthranilate, octyl methoxycinnamate, octyl salicylate, oxybenzone, sulisobenzone, and combinations thereof. Applicants have surprisingly found that the use of such UV-absorbing ingredients do not compromise the light-activated performance of encapsulates of the present invention. Without wishing to be bound by theory, it is believed that in many consumer product applications, e.g., cleaning compositions including laundry detergents, shampoos and body washes, the UV absorbing ingredient is washed down the drain while the encapsulates of the present invention are retained in an efficacious amount on the surface of interest where they are available to release their contents on subsequent exposure to light of a sufficient wavelength. In other cleaning compositions or leave-on consumer products, e.g., floor cleaning compositions, drapery and upholstery refreshers, body lotions, and hair styling products, it is believed that the UV-absorbing ingredients dry down to a thin film after application, allowing the encapsulates of the present invention to sit atop or extend above the film. This allows and efficacious amount of light of the desired wavelength to reach the encapsulates and effect the release of the benefit agents.
The Partitioning Index of an antifoam composition is determined using Nuclear Magnetic Resonance (NMR) analysis of a sample of a Model Detergent.
The Model Detergent composition is made by mixing together the formulation ingredients listed in the Model Detergent Ingredient Table-1 provided herein, in the order and proportions specified1. Once made, the Model Detergent composition is stored in a closed container for 3 days at 20-25° C. before samples are prepared and analyzed via NMR in accordance with the Partitioning Index Test Method specifications provided herein.
1An appropriately sized container is used to contain the mixture. Mixing is done using an overhead mixer equipped with a four-bladed propeller stirrer and 10 cm head diameter (such as the IKA model RW20D-S1 with R 1345 four-bladed propeller stirrer, as available from VWR Randor, Pennsylvania, VWR order catalog number 33994-112).

Two samples are taken from the Model Detergent containing the antifoam composition (which has been aged for 3 days at 20-25° C. after preparation). First sample is prepared by using a plastic pipette to place 5 drops (approximately 0.1 g) of the aged Model Detergent directly into a clean 50 mL round bottom flask (single-necked, 24/40, such as model Z414484 available from Sigma-Aldrich), and then following the dewatering and dissolution instructions provided further below. The second sample is prepared by centrifugation as according to the following instructions prior to undergoing the same dewatering and dissolution procedures specified. The centrifuged sample is prepared by using a disposable plastic pipette to transfer approximately 9 g of the aged Model Detergent with antifoam composition into a labeled centrifuge tube (such as a 10 mL volume, 16 mm×81 mm sized, polypropylene centrifuge tube with Screw-On Cap, as available model #364695 from Beckman Coulter Inc.). This sample is then centrifuged for 4 hours at approximately 30,000 g at 25° C. (such as at 15,300 revolutions per minute using a Beckman Coulter Allegra X-22R Centrifuge equipped with a Beckman F1010 Rotor). After centrifugation, approximately 0.5 mL of the sample is carefully removed from the center (middle level) of the material in the centrifuge tube. A disposable plastic pipette is used to obtain this sample in such a way that contamination from the upper and lower sections of the Model Detergent does not occur. Light pressure may be applied to the bulb of the pipette while inserting and removing the pipette into the sample, causing a few air bubbles to ensure no contamination is acquired from upper portion of the sample. The outer surface of the pipette is carefully wiped clean while still applying pressure to the bulb. Five drops of the centrifuged sample in the pipette are then disposed, and the following 5 drops of centrifuged sample (approximately 0.1 g) are carefully added to a clean 50 mL round bottom flask.
For each of the two samples obtained (i.e., the uncentrifuged sample and the centrifuged sample), dewatering is achieved by using a vacuum pump (such as model 1402N, Welch Chem Star) and adapter (such as 24/40 Vacuum adapter model Z137057, Sigma-Aldrich) to remove water from each sample while applying even heat to each flask for 30 seconds, such that a flask glass temperature of 60° C. is not exceeded. This heating step may employ a heat gun such as the Master Heat Gun Model HG-501A (Master Appliance Corp.). After the heat is removed, the sample is allowed to cool in the flask for 6 min under the reduced pressure provided by the vacuum pump. The pressure is equalized and the adapter removed. For each of the two dewatered samples, a glass pipette is used to add about 1 mL of chloroform-d (such as Chloroform-D, 99.8 ATOM % D, available from Sigma-Aldrich catalogue number 151823) into each flask, to separately dissolved each sample. For each sample, after maximum sample solvation in chloroform is achieved then 0.75 mL of the prepared sample is placed into a clean and labeled NMR tube and sealed with a cap. Suitable NMR tubes include the model Z569267 Colorspec NMR Tubes and caps (Sigma-Aldrich).
Quantitative 1H NMR data is acquired for each prepared sample using an NMR spectrometer equipped with a 5 mm PABBO Z-GRD probe, such as instrument model Avance III HD 400 MHz (Bruker Corp., Billerica, Mass., USA), or equivalent. The instrument is set up with the parameters listed as follows: 30 degree pulse; 1 second recycle delay; 256 scans; PROBHD—5 mm PABBO BB/; PULPROG—zg30; TD—65536; Solvent—CDCl3; DS—2; SWH—8012.820 Hz; FIDRES—0.122266 Hz; AQ—4.0894465 seconds; RG—96.94; DW—62.400 microseconds; DE—17.73 microseconds; TE—297.3 Kelvin; D1—1.0 seconds; TD0—1; SFO1—400.1324710 MHz; NUC1—1H; P1—10.00 microseconds; PLW1—14.21000004 W; SI—65536; SF400.130 MHz; WDW—EM; SSB—0; LB—0.30 Hz; GB—0; PC—1.00. For each of the two samples (i.e., centrifuged and uncentrifuged), the acquired data are analyzed by setting the CDCl3 chemical shift to 7.24 ppm. Software such as the MestReNova LITE Version 5.2.5-5780 (Mestrelab Research S.L.) is used to quantitatively integrate a unique chemical shift of the organomodified silicone, and to quantitatively integrate the unique chemical shift of the aromatic proton from 7.60 to 7.85 ppm. One example of a suitable unique shift in a specific given siloxane is the methyl group of the 2-phenylpropylmethylsiloxane repeat unit at -0.20 to -0.09 ppm. The chemical shift of the aromatic proton at 7.60 to 7.85 ppm is normalized to a value of 20, and the resultant normalized integral value of the organomodified silicone chemical shift is recorded.
The Partitioning Index of the antifoam composition is calculated using the following formula:
The Partitioning Index of the antifoam composition=
Silica surfaces that have been modified with non-hydrolysable organic molecules (i.e., made more hydrophobic) may be poorly wetted by water; however such hydrophobic silicas may become wetted after exposure to aqueous methanol. Silica is classified herein as either Wetted or Non-Wetted, according to its sedimentation behavior in aqueous methanol. Silica that forms sediment in aqueous methanol after centrifugation under specified conditions is defined as Wetted silica, while the non-sedimenting silica is defined as being Non-wetted. The volume of silica that is wetted upon exposure to a given concentration of aqueous methanol is a measure of the hydrophobicity of the modified silica, and is used herein to determine the Methanol Absorption Index of the silica.
Two aqueous methanol solutions are prepared using deionized water (DI), to yield a 54% (wt/wt) methanol solution, and also a 90% (wt/wt) methanol solution. The 90% methanol solution serves as a positive control reference point which achieves maximum wetting of the silica. Prior to testing, the silica is preconditioned by allowing it to equilibrate with atmospheric conditions within the range of 21° C. to 25° C. in temperature, and within the relative humidity range of 20% RH to 50% RH. The conditioned silica is mixed thoroughly and allowed to settle for several minutes, to ensure homogeneity before sampling. Sampling of the silica results in paired aliquots of silica, wherein one pair comprises one replicate. At least two replicate pairs of aliquots are prepared from each silica being tested. For each replicate pair, two aliquots of the silica are weighed out, wherein each aliquot in the pair comprises 200 mg+/−1 mg of silica which is placed into a centrifuge tube. The centrifuge tubes are 15 mL capacity transparent plastic tubes with screw top lids and a graduated volumetric scale, wherein the scale has graduations of 0.5 mL and 0.1 mL for at least the first 1 mL of volume. Suitable tubes include the model #21008-197 available from VWR International LLC, Radnor, Pa., USA. Methanol solution is added to both tubes in each replicate pair of tubes. One tube in each pair receives 8 mL of the 54% methanol solution, while the other tube in the pair receives 8 mL of the 90% methanol solution. Each tube containing silica sample and methanol solution is then sealed with a lid.
Each sealed sample tube is vigorously shaken by hand ten times in a vertical up and down motion, and is then immediately vortexed for 45 seconds on a benchtop vortex mixer (such as Mini-vortexer model #58816-121 from VWR International LLC, Radnor, Pa., USA) using the maximum speed setting. After shaking and vortexing, the mixing process is repeated such that each sample tube is shaken and vortexed twice. Immediately after the mixing is complete each tube is placed into a centrifuge and centrifuged at an average relative centrifugal force (RCF) of 851 g for 5 minutes, at 25° C. One instrument suitable for this process is the model Allegra X-22R Centrifuge equipped with SX4250 Rotor and adapter #392253 run at 2500 RPM (as available from Beckman Coulter Inc., Brea, Calif., USA).
Immediately after the centrifugation is complete, the volume of sediment in each centrifuged sample tube is determined by reading the graduated scale markings on the tube, with an accuracy of 0.05 mL. For each silica, the measured volumes obtained from at least two replicates of paired samples are used to separately calculate the average sediment volume for each of the two methanol concentrations. For each silica, the ratio is then calculated using the average sediment volumes that were obtained from the two different methanol concentrations, wherein the average result from the lower methanol concentration (i.e., 54%) is divided by the average result from the higher methanol concentration (i.e., 90%). This ratio of the sediment volumes is then multiplied by 100, to yield the Methanol Absorption Index value of that silica, which is the reported value. These calculations are conducted for each silica in accordance with the equation below:
Methanol Absorption Index=(Sediment in low/Sediment in high)×100
wherein:
Sediment in low=the average volume of sediment (in mL) in 54% methanol, and Sediment in high=the average volume of sediment (in mL) in 90% methanol.
The liquid detergent containing the antifoam composition was tested using the Antifoam Performance Test within 24 hours of making the detergent. The composition is then stored in a controlled temperature and humidity at 32.2° C. and 80% relative humidity. After 1, 2 and 3 months of storage the composition is retested for the antifoam performance.
The fabric load used in the Antifoam Performance Test consists of six 100% cotton T-shirts, six 50/50 polyester/cotton blend pillowcases, and six 86/14 polyester/cotton blend towels, totaling 8-8.5 lb. A clean, dry fabric load must be used for each test replicate. If the fabric load is reused, it is thoroughly cleaned in a Kenmore 600 series washing machine or equivalent using the heavy duty or cotton/sturdy setting, hot water at 60° C. (±3° C.), and 90.72 g of liquid Tide® Free or equivalent. The washing is repeated two times. The fabric load is washed third, fourth and fifth time after the conclusion of the previously described second cycle with the exception that no detergent is added during the third, fourth, and fifth cycles. During the fifth cycle, there should be no suds visible in the washing machine during the wash or rinse portions of the wash cycle. If suds are present, additional cycles, with the same wash cycle parameters as described above for the first wash cycle, are ran with the exception that no detergent is added to these additional cycles. These additional cycles continue to be repeated until no suds are present during the wash and rinse cycles. Once no suds are observed in the wash or rinse portions of the wash cycle, the fabric load is removed from the washing machine and dried in an electric dryer on the high heat setting for approximately 55 minutes or until the fabric load is completely dry.
A dose of 46.55 g of the liquid detergent to be tested is weighed in plastic cups. A Whirlpool® Duet front loading washing machine, model number GHW9100, or equivalent is used for measuring the antifoam performance in the Antifoam Performance Test. The length of each wash cycle is measured with a digital timer. The washing machines are cleaned prior to use by running them through a wash cycle, empty (without fabric load or detergent) with soft water at 49° C. (±1°). This cycle is repeated until no suds are observed during the cycle. This cleaning procedure is conducted between each cycle in which a detergent product with antifoam is tested.
Once the washing machine is cleaned, the fabric load is then placed to the washing machine. The pre-weighed detergent in the plastic cup described above is emptied into the washer dosing drawer. The plastic cup in which the sample was weighed is placed into the back of the drum of the washer. The Antifoam Performance Test is ran using a normal wash cycle with soft water (zero grains/gal hardness) at a temperature of 37° C. (±3°) during the wash cycle and 21° C. (±3°) rinse cycle. The hardness and temperature of the water are monitored throughout the duration of the test. The washing machine should not be paused at any time during the test.
The suds height data and the state of the washing machine, such as spinning, filling, tumbling, draining, and suds lock, are recorded every 2 minutes. The suds height is measured by assigning a score of 0 to 4 every two minutes, with 0 indicating no suds are present, 1 indicating suds are present among the clothes, 2 indicating suds are one-third of the way up the window, 3 indicating suds are two-thirds of the way up the window, and 4 indicating the suds are covering the window completely. At the end of the cycle, the digital timer on the washing machine must be stopped within 5 seconds of the washing machine stopping. The time displayed on the digital timer is recorded as the actual total cycle time. The test is repeated three times for each test product and the cycle time results are averaged to determine the performance of the antifoam.
The sample is designated to have a “Pass” grade if all of the following criteria are met. It is designated to have a “Fail’ grade if any one of the criteria are not met:
A preliminary estimate of the sample viscosity at 25° C. and 6.325 s−1 is used to select the appropriate instrument geometry to be used during the final viscosity measurement analyses, which are conducted on a model AR-G2 Rheometer (manufactured by TA Instruments Corp., New Castle, Del., USA). A preliminary estimate of the sample viscosity may be obtained by using a Brookfield Viscometer (Brookfield Engineering Laboratories Inc., Middleboro, Mass., USA). The selection of geometry for use on the AR-G2 Rheometer is determined in accordance with the following table, Table-2:
The geometry attached to the instrument, the instrument is mapped, the gap distance is zeroed, and the instrument temperature is set to 25° C. The measurement mode is selected as Stiff Mode when using parallel plates, or to Soft mode when using the couett cup and bob geometry. Sample material is mounted into the sample holding geometry e.g., the base plate. The minimum gap distance allowable between the base plate and the selected geometry is 10× the diameter of the largest common particle present in sample. If there are common particles in the sample which have a diameter greater than 100 μm (as determined microscopically), then the gap value is set to 10× the diameter of the largest common particle, otherwise the gap distance is set to the default value of 1000 μm (ie 1 mm). The selected geometry is lowered to the appropriate gap and a plastic tool is used to trim off any excess sample material. The sample material is allowed to equilibrate to the temperature of the instrument. Three rheological measurement analyses are conducted, namely: Flow Curve, Stress Sweep, and Frequency Sweep, using the following selections and settings:
To ensure that the analysis is conducted within the Linear Viscoelastic Region set the Stress value at a third of the stress value that was present when G′ started to degrade during the prior Stress Sweep analysis.
The viscosity value for the test material obtained at 6.325 s−1 at 25° C. is reported as the viscosity value of the sample in cSt, ±300 cSt.
In order to conduct the calculations involved in the computed-value test methods described herein, the starting information required includes the identity, weight percent, and molar percent of each non-cyclic aliphatic moiety being tested, as a proportion of that mixture, wherein all non-cyclic aliphatic moiety in the mixture composition are included in the calculations. Additionally for each of those non-cyclic aliphatic moiety, the molecular structure, and the values of various computationally-derived molecular descriptors are also required, as determined in accordance with the Test Method for the Generation of Molecular Descriptors described herein.
The value of the log of the Octanol/Water Partition Coefficient (log P) is computed for each non-cyclic aliphatic moiety in the mixture composition being tested. The log P of an individual non-cyclic aliphatic moiety is calculated using the Consensus log P Computational Model, version 14.02 (Linux) available from Advanced Chemistry Development Inc. (ACD/Labs) (Toronto, Canada) to provide the unitless log P value. The ACD/Labs' Consensus log P Computational Model is part of the ACD/Labs model suite.
For each non-cyclic aliphatic moiety in a mixture composition its molecular structure is used to compute various molecular descriptors. The molecular structure is determined by the graphic molecular structure representations provided by the Chemical Abstract Service (“CAS”), a division of the American Chemical Society, Columbus, Ohio, U.S.A. These molecular structures may be obtained from the CAS Chemical Registry System database by looking up the index name or CAS number of each non-cyclic aliphatic moiety. For non-cyclic aliphatic moieties, which at the time of their testing are not yet listed in the CAS Chemical Registry System database, other databases or information sources may be used to determine their structures. For a non-cyclic aliphatic moiety which has potentially more than one isomer present, the molecular descriptor computations are conducted using the molecular structure of only one of the isomers, which is selected to represent that non-cyclic aliphatic moiety. The selection of isomer is determined by the relative amount of extension in the molecular structures of the isomers. Of all the isomers of a given non-cyclic aliphatic moiety, it is the isomer whose molecular structure is the most prevalent by weight % which is the one that is selected to represent that non-cyclic aliphatic moiety. The structures for other potential isomers of that non-cyclic aliphatic moiety are excluded from the computations. The molecular structure of the most prevalent isomer is paired with the concentration of that non-cyclic aliphatic moiety, where the concentration reflects the presence of all the isomers of that non-cyclic aliphatic moiety that are present.
A molecule editor or molecular sketching software program, such as ChemDraw (CambridgeSoft/PerkinElmer Inc., Waltham, Mass., U.S.A.), is used to duplicate the 2-dimensional molecular structure representing each non-cyclic aliphatic moiety. Molecular structures should be represented as neutral species (quaternary nitrogen atoms are allowed) with no disconnected fragments (e.g., single structures with no counter ions). The winMolconn program described below can convert any deprotonated functional groups to the neutral form by adding the appropriate number of hydrogen atoms and will discard the counter ion.
For each non-cyclic aliphatic moiety, the molecular sketching software is used to generate a file which describes the molecular structure of the non-cyclic aliphatic moiety. The file(s) describing the molecular structures of the non-cyclic aliphatic moieties is subsequently submitted to the computer software program winMolconn, version 1.0.1.3 (Hall Associates Consulting, Quincy, Mass., U.S.A., www.molconn.com), in order to derive various molecular descriptors for each non-cyclic aliphatic moiety. As such, it is the winMolconn software program which dictates the structure notations and file formats that are acceptable options. These options include either a MACCS SDF formatted file (i.e., a Structure-Data File); or a Simplified Molecular Input Line Entry Specification (i.e., a SMILES string structure line notation) which is commonly used within a simple text file, often with a “.smi” or “.txt” file name extension. The SDF file represents each molecular structure in the format of a multi-line record, while the syntax for a SMILES structure is a single line of text with no white space. A structure name or identifier can be added to the SMILES string by including it on the same line following the SMILES string and separated by a space, e.g.: C1=CC═CC=C1 benzene.
The winMolconn software program is used to generate numerous molecular descriptors for each non-cyclic aliphatic moiety, which are then output in a table format. Specific molecular descriptors derived by winMolconn are subsequently used as inputs (i.e., as variable terms in mathematical equations) for a variety of computer model test methods in order to calculate values such as: logarithm of the Octanol/Water Partition Coefficient (log P). The molecular descriptor labels used in the models' test method computations are the same labels reported by the winMolconn program, and their descriptions and definitions can be found listed in the winMolconn documentation. The following is a generic description of how to execute the winMolconn software program and generate the required molecular structure descriptors for each non-cyclic aliphatic moiety in a composition.
