Patent Application
20190010293
The present application relates to silicone compounds, compositions, packaged products and displays comprising such silicone compounds, and processes for making and using such compositions, packaged products and displays comprising such compositions.
Benefit agents, such as perfumes, brighteners, insect repellants, silicones, waxes, flavors, vitamins and fabric softening agents, skin care agents are expensive and may be less effective when employed at high levels in personal care compositions, cleaning compositions, and fabric care compositions. As a result, there is a desire to maximize the effectiveness of such benefit agents. One method of achieving such objective is to improve the delivery efficiencies of such benefit agents. Unfortunately, it is difficult to improve the delivery efficiencies of benefit agents as such agents may be lost due to the agents' physical or chemical characteristics, such agents may be incompatible with other compositional components or the situs that is treated, or such agents may be lost during post application processes such as rinsing or drying. In an effort to improve the delivery efficiencies of benefit agents, the industry developed perfume amine compounds and perfume thiol compounds. Such compounds were the result of the reaction of a perfume comprising an aldehyde moiety and/or ketone moiety with a carrier that comprised a primary amine, secondary amine and/or thiol moiety. Unfortunately such compounds could only provide limited scents as such compounds were limited to perfumes that contained an aldehyde or ketone moiety. In addition, such compounds were not as effective as desired as they did not deposit on a situs as efficiently as desired.
One solution to the aforementioned problem is silicone compounds that are conjugates of a silicone and a benefit agent, for example a perfume. The aforementioned conjugation is typically achieved by forming a covalent bond between the functionalized portion of the silicone and the benefit agent. Thus, the silicone typically needs to be a functionalized silicone.
Unfortunately, functionalized silicones can reduce the benefits of compositions such as cleaning compositions if such compositions are not formulated with the use of functionalized silicones in mind and/or have other use limitations.
Applicants recognized that such formulation challenges are rooted in the charge of functionalized silicones as the degree of charge and degree of functionalization are interrelated and/or the ability of the functionalized portion of the functionalized silicone to cleave from such functionalized silicone. While one can alter the charge of functionalized silicones by reducing the overall functionalization content of the silicone, such alteration can result in negatives such as a loss in the primary benefits of the functionalized silicones. For example, the reduction of the amino functionalization of an aminosilicone can result in a loss in feel and/or benefit delivery effectiveness. Thus, what is needed are silicone compounds that comprise functionalized silicones that retain all the primary benefits of a functionalized silicone during use, yet which change their hydrophilicity/charge and/or demonstrate cleavage of the functionalized silicone's functionalization when desired, for example, after use. Applicants provide such a silicone compound by employing a functionalized silicone that incorporates a moiety comprising a cleavable bond between the silicone backbone and the desired functionalization. Such silicone compounds solve the further problem of malodor reduction as, in addition to maldor masking, such compounds block a malodor's access to a sensory cell, yet leave such sensor cell open to other molecules, for example scent molecules. Thus, the malodor control technologies disclosed herein do not unduly interfere with the scent of the perfumed or unperfumed situs that is treated with the malodor control technology.
The present application relates to silicone compounds, compositions, packaged products and displays comprising such silicone compounds, and processes for making and using such compositions, packaged products and displays comprising such compositions.

The logP values of many perfume ingredients have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS, Irvine, Calif.), contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the “CLOGP” program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database. The “calculated logP” (ClogP) is determined by the fragment approach of Hansch and Leo (cf., A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, P. G Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990, incorporated herein by reference). The fragment approach is based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental logP values in the selection of perfume ingredients which are useful in the present invention.
It is understood that the test methods that are disclosed in the Test Methods Section of the present application should be used to determine the respective values of the parameters of Applicants' invention as such invention is described and claimed herein.
A preliminary estimate of the sample viscosity at 25° C. 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:
Flow Curve: select Stepped Flow 0.01 to 100; 10 pts/decade; shear stress; constant time 20;
average last 10.
Stress Sweep: set the Stress Range as 0.01 to 100 Pa; set the Frequency at 1 rad/s.
Frequency Sweep: Set the Angular Frequency Range as 0.1 to 100.
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 25° C. is reported.
The Amine Equivalent method is an ASTM standard D2074-07, but with the extra step of converting from Amine Value (meq/g) to Amine Equivalent (g/mol) as follows:
Amine Equivalent (g/mol)=1000/Amine Value (meq/g)
Method for assigning the Blocking Index (BI) to Test Samples Using a BI Reference Scale
The first step in the method for assigning a BI to a test sample material on the BI reference scale is to create the BI reference swatches. The swatches for the scale are created by treating clean fabrics swatches with a known amount of a known volume of isovaleric acid solution at a known concentration. Fabric swatches for this test are white knit polycotton (4 inch×4 inch) swatches from EMC ordered as PC 50/50. The supplier is instructed to strip the swatches first, stripping involves washing twice with a fragrance-free detergent and rinsing three times.
Make one solution of 0.08% isovaleric acid using 50%/ 50% EtOH/water as the diluent. The BI scale contains one clean swatch with no malodor applied. Three other swatches each have a different volume of the 0.08% isovaleric acid applied. Pipette 2μL, of the 0.08% isovaleric acid solution to one clean swatch, 5 pL of the 0.08% isovaleric acid solution to the next swatch and 20 μL of isovaleric acid to the final clean swatch. These solutions are pipetted to the middle of the swatches. This will create a sensory scale of three swatches with three different odor levels based on the volume of the 0.08% isovaleric acid solution pipetted onto the swatches. After drying for 30 minutes in a vented hood, the swatches are wrapped in aluminum foil to prevent odor contamination to the treated swatch. A clean untreated swatch is also included as the lowest anchor point of reference for malodor strength on the BI scale. The BI reference scale swatches should be used within 0.5 to 12 hours and discarded after 12 hours. The swatches are used as scale anchor points when graders evaluate a test sample(s) and are assigned a Blocker Index (BI) as show in Table 12.
At least three perfumers/expert graders are used to rank the isovaleric acid swatches in the BI scale. The perfumer/expert grader needs to demonstrate adequate discrimination on the scale. The perfumer/expert grader is asked to rank order swatches according to a scale between 0 and 3. The panel of graders must demonstrate statistical differences between the swatches (for additional details on training graders see as seen in US 2016/0090555 A1, starting on p 35 column 1, paragraph[0212] and ending on p 25 column 2 at and including Table 12, with the only difference being, 3 graders are used for the purposes of the present invention.
Making the Malodorous Swatches for Blocker Index Grading and Treating it with a Test Detergent
To evaluate the BI of test detergents containing the test materials (MOC oil or MOC reacted with silicone), first prepare swatches stained with body soil malodor composition. To create the body soil malodor composition first the malodor composition is made according to the formulation in Table A.
Next the body soil malodor composition is made by providing the specified amount of each material according to the Table B into a 200 mL glass jar with Teflon lined cap. Artificial body soil (ABS) is commercially available by Accurate Product Development; 2028 Bohlke Blvd, Fairfield, Ohio 45014.
The composition in Table B is used to prepare the swatches stained with the malodor body soil composition. Apply 300 μl of body soil malodor composition described in Table B to de-sized 4×4 inch PC 50/50 swatches from EMC.
To treat the stained swatches, 48 grams of liquid detergent according to Table 1B of Performance Example 1 is added to Duet 9200 washing appliance set to Normal cycle; 77° F. wash cycle followed by a 60° F. rinse cycle. Malodor test fabrics are washed in 7gpg wash water with 3.9 kg, 50×50 cm clean cotton and poly-cotton ballast then dried in a Maytag double stack tumble drier set to low for 20 minutes. The dried fabrics are placed in a mylar bag and sealed for 24 hours.
After 24 hours, at least three perfumers/expert graders are used to assign the BI to the test sample. The expert grader smells the isovaleric acid + test material swatch by holding that swatch one inch from their nose and then assigns the isovaleric acid + test material swatch a BI based on ranking its odor strength against the odor strength of the swatches in the BI reference scale. The test sample swatch is assigned a BI at or between numbers on the BI in table. In cases where the isovaleric acid + test material swatch odor is greater than 3 on the BI reference scale, this indicates the material is not a blocker.
