The present invention relates to compositions containing a hydrocarbyl functional organopolysiloxane and an organopolysiloxane resin. The hydrocarbyl functional organopolysiloxane contains at least one siloxy unit of the formula —R2OCH2CH2OH, where R2 is a divalent hydrocarbon group containing 2 to 6 carbon atoms. The combination of the hydrocarbyl functional organopolysiloxane and organopolysiloxane resin provides a base composition with improved film properties that can be used in various personal, medical, automotive and household care compositions.
A successful color cosmetic composition usually encompasses 3 key elements to optimize performance of the final product. These elements can be described as; the color film formed on the skin, the pigments that are used to formulate the product, and the structure or texture of the color cosmetic that has been selected. Each of these elements require a specific attention about its fundamental behavior, as each interacts with each other causing a different behaviors and results from what the formulator expects, some times causing defects or poor performance in the final color product.
Perhaps one of the most critical requirements for a color cosmetic is the film formation. If the film is not uniform, the optimum color development of the final product will not occur, the film gloss will be affected and the final color cosmetic product will show poor performance.
Films can be formed in several ways. The simplest method is to dissolve all the ingredients in a solvent or solvents to achieve the desired application viscosity, then apply the product on the skin and then allow the solvent to evaporate. However, many factors affect film formation such as; wet-ability, compatibility, rheology, pigment content, substrate properties and solvent system properties among others. The control of these factors will allow the formulator to create films with good properties such as: slipperiness, resistance to mild abrasion, leveling, good spread-ability, water resistance, adhesion and gloss.
A good film often depends on three key formulating factors, compatibility, viscosity, and wetting.
Compatibility: where various components exist in one formulation without any interactions. The components of the system should form homogeneous (one-phase) mixtures at given ratios (thermodynamic compatibility). The system should not present separation of any ingredient (two or more phases), precipitation or the presence of any suspend agents (graininess, lumps, etc.) The system can be clear or transparent (soluble) or hazy or opaque, but all ingredients should coexist in one phase. In the case of coatings the system should form a homogeneous film on the substrate. If the ingredients used in the composition are only partially compatible (that is have miscibility limits). A compatibilizer is needed to maintain the homogeneous state of the composition.
Viscosity: The viscosity of a coating also influences wetting and surface defect formation, the rate of wetting is dependent on viscosity as well as surface tension. Even if other conditions are favorable (surface tension, contact angle, etc.) Spontaneous spreading or de-wetting may not occur if viscosity is too high. Surface defects may or may not form, depending on viscosity.
Wetting: Wetting involves the interaction of a liquid with a solid; it can be the spreading of a liquid over a surface, the penetration of a liquid into a porous medium, or the displacement of one liquid by another.
Thus, there is a need for compositions having improved film properties that can be used as a base in cosmetic compositions. In particular, there is a need for base compositions for use in cosmetics that are compatible with common ingredients used in color cosmetics, allow for adjustment of the viscosity of the cosmetic films upon application, and provide adequate wetting of the surface of skin upon application. Furthermore, such base compositions should possess aesthetics qualities to allow for the formulation of appealing consumer cosmetic products.
The present inventors have discovered such a base composition containing a hydrocarbyl functional organopolysiloxane and an organopolysiloxane resin.
The present invention provides a composition comprising;
This invention also relates to cosmetic, household, or health care formulations comprising the composition of the present invention.
The hydrocarbyl functional organopolysiloxane of the present invention comprises a siloxy unit of the formula R1RiSiO(3−i)/2 wherein R is any monovalent hydrocarbon group, but typically is an alkyl, cycloalkyl, alkenyl, aralkyl, or an aryl group containing 1-20 carbon atoms, R1 is a hydrocarbyl group having the formula —R2OCH2CH2OH, R2 is a divalent hydrocarbon group containing 2 to 6 carbon atoms, i is zero to 2.
Organopolysiloxanes are well known in the art and are often designated as comprising any number of M units (R3SiO0.5), D units (R2SiO), T units (RSiO1.5), or Q units (SiO2) where R is independently any monovalent hydrocarbon group. In the present invention, the organopolysiloxane has at least one hydrocarbyl substituent of the formula —R2OCH2CH2OH, designated as R1. The R2 group in the hydrocarbyl substituent is a divalent hydrocarbon group containing 2 to 6 carbon atoms. The R2 divalent hydrocarbon is represented by an ethylene, propylene, butylene, pentylene, or hexylene. Typically, the divalent hydrocarbon is a propylene group, —CH2CH2CH2—.
The hydrocarbyl substituent is bonded to the organopolysiloxane via a Si—C bond. The hydrocarbyl substituent can be present in the organopolysiloxane via linkage to any organosiloxy unit, that is it may be present on any M, D, or T siloxy unit. In other words, the hydrocarbyl functional siloxy unit can be a M unit (R1R2SiO0.5), a D unit (R1RSiO), a T unit (R1SiO1.5), or a mixture of any of these. The hydrocarbyl functional organopolysiloxane can also contain any number of additional M, D, T, or Q siloxy units of the general formula (R3SiO0.5), (R2SiO), (RSiO1.5), or (SiO2), providing that the organopolysiloxane has at least one siloxy unit with the R1 present.
The weight average molecular weight (MW) or number average molecular weight (MN) of the hydrocarbyl functional organopolysiloxane can vary, and is not limiting. The hydrocarbyl functional organopolysiloxane can be either liquid or solid in form, but are generally liquids.
The amount of the hydrocarbyl functional groups present in the organopolysiloxanes of the present invention can vary, but typically ranges from 1 to 40 mass percent, alternatively from 5 to 30 mass percent, or alternatively from 10 to 20 mass percent of the total mass of the organopolysiloxane.
In one embodiment, the hydrocarbyl functional organopolysiloxane has a formula selected from the group:
In these formulas, R is an alkyl, cycloalkyl, alkenyl, aralkyl, or an aryl group containing 1-20 carbon atoms; R1 is the hydrocarbyl group as defined above, x is 1-500, y is 1-40, z is 1-40, m is 1-6, n is 1-6, and the sum of m+n is 3-12.
In the alternate embodiment, the hydrocarbyl functional organopolysiloxane is a resin having the formula;
(SiO2)c(R3SiO3/2)d(R32SiO)e(R33SiO1/2)f{O1/2SiR32R4}g
where R3 is an alkyl group with 1-20 carbon atoms, a cycloalkyl group with 3-20 carbon atoms, an alkenyl group with 2-20 carbon atoms, an aralkyl group, or an aryl group; R4 is the same as R1 above, i.e., one of the formulas (i) to (iv); and g is 1-15,000. In such resins, c, d, e, and f represent mole percents, such that c<100, c+d>0, and c+d+e+f is 100. Organosiloxane resins of this type typically contain about 0.01-15 weight percent of silanol.
In a preferred embodiment, the hydrocarbyl functional organopolysiloxane has the formula
R1Me2SiO(Me2SiO)xSiMe2R1
where R1 is —(CH2)3OCH2CH2OH and x is 1 to 100, alternatively 5 to 50, or alternatively 10 to 20.
The hydrocarbyl functional organopolysiloxanes of the present invention can be made by standard processes such as the hydrosilylation of organohydrogensiloxanes and olefinically substituted polyoxyalkylenes. The hydrosilylation reaction is typically performed in a low molecular weight volatile hydrocarbon solvent such as benzene, toluene, xylene, or isopropanol to aid in handling the reactants, to moderate an exothermic reaction or to promote the solubility of the reactants. Such processes are described, for example, in the '218 patent noted above, which is incorporated herein by reference.
The composition of the present invention also contains (ii) an organopolysiloxane resin comprising various siloxy units such as (i) (R3SiO1/2)a, (ii) (R2SiO2/2)b, (iii) (RSiO3/2)c, or (iv) (SiO4/2)d units which are commonly known in the art, and also used herein, as M, D, T, and Q units respectively. The amount of each siloxy unit present in the organopolysiloxane resin can be expressed as a mole fraction of the total number of moles of all siloxy units present in the organopolysiloxane resin. Thus, the organopolysiloxane resins useful in the present invention comprise the units:
In one embodiment of the present invention, the organopolysiloxane resin is a MQ resin comprising at least 80 mole % (R3SiO1/2)a and (SiO4/2)d units where R is a monovalent hydrocarbon group, a and d has a value greater than zero, and the ratio of a/d is 0.5 to 1.5.
MQ resins suitable for use as component ii), and methods for their preparation, are known in the art. For example, U.S. Pat. No. 2,814,601 to Currie et al., Nov. 26, 1957, which is hereby incorporated by reference, discloses that MQ resins can be prepared by converting a water-soluble silicate into a silicic acid monomer or silicic acid oligomer using an acid. When adequate polymerization has been achieved, the resin is end-capped with trimethylchlorosilane to yield the MQ resin. Another method for preparing MQ resins is disclosed in U.S. Pat. No. 2,857,356 to Goodwin, Oct. 21, 1958, which is hereby incorporated by reference. Goodwin discloses a method for the preparation of an MQ resin by the cohydrolysis of a mixture of an alkyl silicate and a hydrolyzable trialkylsilane organopolysiloxane with water.
The MQ resins suitable as component ii) in the present invention may contain D and T units, providing that at least 80 mole %, alternatively 90 mole % of the total siloxane units are M and Q units. The MQ resins may also contain hydroxy groups. Typically, the MQ resins have a total weight % hydroxy content of 2-10 weight %, alternatively 2-5 weight %. The MQ resins can also be further “capped” wherein residual hydroxy groups are reacted further with M groups.
The compositions according to the invention can be formed by combining the hydrocarbyl functional organopolysiloxane component and the organopolysiloxane resin component, as described above, at a weight ratio of 1:99 to 99:1. Such compositions can generally be prepared at room temperature, using simple propeller mixers, Brookfield counter-rotating mixers, or homogenizing mixers. No special equipment or processing conditions are typically required.
The organopolysiloxane resins can be used neat, or alternatively, the organopolysiloxane resin can be dissolved in a carrier. The carrier can be any organic or silicone based solvent, which are further described infra.
Representative, non-limiting, examples of a commercial products suitable for use as component ii) include; Dow Corning ® 749 Fluid, Dow Corning ® 593, Dow Corning ® 7-4405 Cosmetic Fluid, Dow Corning® 2400 Resin, (Dow Corning Corporation, Midland Mich.),
The compositions of the present invention can be further combined with a personal care ingredient, household care ingredient, or health care ingredient. Such compositions can contain; (i) 0.1-99.9 percent of the hydrocarbyl functional organopolysiloxane fluid or the hydrocarbyl functional organopolysiloxane resin; (ii) 0.1 to 99.9 percent of the sunscreen agent; optionally (iii) 0.1-40 percent of a cosmetic active, household care active, or health care active; and (iv) the balance to 100 percent being water, an organic solvent, a silicone solvent, or one or more optional ingredients, depending upon the particular type of composition being prepared, and its intended end use or application. Generally, such compositions can generally be prepared at room temperature, using simple propeller mixers, Brookfield counter-rotating mixers, or homogenizing mixers. No special equipment or processing conditions are typically required.
As used herein, the terms personal care composition, health care composition, and household care composition are intended to mean typical materials commercially available as products or raw materials in consumer markets containing active and inactive ingredients.

Also included are automotive products, such as, waxes, polishes, heavy and light duty cleaners, window cleaners, tire cleaners and protectors, vinyl cleaners and protectors, and the like.
Some typical ingredients used in these products are surfactants, pigments, solvents, emollients, and carriers. For example, the solvents can include esters (for example, isopropyl myristate and C12-15 alkyl lactate), water, silicone fluids (for example, cyclomethicone, dimethicone), ethanol, isopropanol, guerbet alcohols having 8-30 carbons, particularly 12-22 carbons (for example, isolauryl alcohol, isocetyl alcohol, isostearyl alcohol), fatty alcohols (for example, stearyl alcohol, myristyl alcohol, oleyl alcohol), and ethoxylated and propoxylated alcohols (for example, the polyethylene glycol ether of lauryl alcohol that conforms to the formula CH3(CH2)10CH2(OCH2CH2)r OH where r has an average value of 4 (Laureth-4); PPG-14 butyl ether, where the “PPG-14” portion is the polymer of propylene oxide that conforms generally to the formula H(OCH2C(CH3)H)sOH, where s has an average value of 14, or PPG-3 myristyl ether which is the polypropylene glycol ether of myristyl alcohol that conforms to the formula CH3(CH2)12CH2(OCH(CH3)CH2)tOH where t has an average value of 3, or a hydrocarbon fluid.
Hydrocarbon fluids are exemplified by organic hydrocarbon fluids such as halogenated hydrocarbon fluids, aliphatic hydrocarbon fluids, aromatic hydrocarbon fluids, and mixtures of aromatic and aliphatic hydrocarbon fluids. The hydrocarbon fluids usually contain about 6 to about 12 carbon atoms. Examples of suitable hydrocarbon fluids include perchloroethylene, benzene, xylene, toluene, mineral oil fractions, kerosenes, naphthas, and petroleum fractions. Particularly preferred are isoparaffinic hydrocarbon fluids exemplified by isoparaffin fluids available from Exxon Mobil Chemical Company, Houston, Tex. U.S.A., sold as Isopar® M Fluid (a C13-C14 Isoparaffin), Isopar® C Fluid (a C7-C8 Isoparaffin), Isopar® E Fluid (a C8-C9 Isoparaffin), Isopar® G Fluid (a C10-11 Isoparaffin), Isopar® L Fluid (a C11-C13 Isoparaffin), Isopar® H Fluid (a C11-C12 Isoparaffin), and combinations thereof. Mixtures of solvents can also be used.
Another ingredient which can be used is an emollient, including compositions such as guerbet alcohols (such as isocetyl alcohol or isostearyl alcohol); esters (such as isopropyl palmitate, isopropyl isostearate, octyl stearate, hexyl laurate and isostearyl lactate); a liquid mixture of hydrocarbons which are liquids at ambient temperatures (such as petroleum distillates and light mineral oils); ethanol; volatile and non-volatile silicone oils, highly branched hydrocarbons, and non-polar carboxylic acids. The emollients can be included in the compositions of the present invention in amounts within the range of 0.01-70%, preferably 0.1-25%, by weight, of the total weight of the composition.
The carrier can include a wide variety of conditioning materials, such as hydrocarbons, silicone fluids, and cationic materials. The carrier can include surfactants, suspending agents, thickeners etc. Various additional components useful in these compositions are described in U.S. Pat. No. 4,387,090 (Jun. 7, 1983).
Topical cosmetic, and pharmaceutical compositions according to the invention can contain a carrier, but the carrier should be cosmetically and/or pharmaceutically acceptable, i.e., that it is suitable for topical application to the skin, has good aesthetic properties, is compatible with the siloxane copolymers of the present invention, and will not cause any safety or toxicity concerns. It can be formulated to include an emulsion as the carrier such as an oil-in-water emulsion, water-in-oil emulsion, water-in-oil-in-water emulsion, or oil-in-water-in-silicone oil emulsion.
Some other suitable topical carriers include anhydrous liquid solvents such as oils, alcohols, and silicones (e.g., mineral oil, ethanol, isopropanol, dimethicone, cyclomethicone, and the like); aqueous-based single phase solvents (e.g., where the viscosity of the solvent has been increased to form a solid or semi-solid by the addition of appropriate gums, resins, waxes, polymers, salts, and the like). However, the preferred cosmetically and/or pharmaceutically acceptable topical carrier is a hydroalcoholic system or an oil-in-water emulsion. When the carrier is an oil-in-water emulsion, it will include common ingredients generally used for preparing emulsions.

The following examples are presented to further illustrate the compositions and methods of this invention, but are not to be construed as limiting the invention. All parts and percentages in the examples are on a weight basis and all measurements were obtained at about 23° C., unless indicated to the contrary.
In the representative examples that follow, the ingredient listed as “Carbinol fluid” is Dow Corning® 5562 Carbinol fluid (Dow Corning Corporation, Midland Mich.), a hydrocarbyl functional organopolysiloxane having the formula,
R1Me2SiO(Me2SiO)xSiMe2R1 where R is —(CH2)3OCH2CH2OH, and x is such to provide the product with a viscosity of about 50 cS (mm2/s) at 23° C.
The Carbinol Fluid was evaluated as a wetting agent in an un-pigmented coating composition containing a silicone resin and carrier. For comparison, other commonly used wetting agents were also evaluated. These included; Dow Corning ® 5211 (Dimethicone Copolyol) from Dow Corning Corporation, Midland Mich., a silicone polyether wetting agent, Crodamol PTIS (Pentaerythrityl Tetraisostearate) from Croda Inc., Edison, N.J., (US division of Croda International Plc), and castor oil. The coating compositions contained 10 wt % wetting agent, a Silicone Resin at 20 wt % solids, and 70 wt % carrier. The carriers used were Cyclomethicone (D5) and Isododecane. The silicone resins used in the coating compositions were; Dow Corning® SR 2400, Dow Corning® 749 Fluid, Dow Corning® 7-4405 Cosmetic Fluid, Dow Corning Corporation, Midland, Mich. The coatings were applied on a Lenetta chart using a Maylard coating rod No 8. The resulting films were characterized by visual observations and measurements of 60° gloss with a Gardner Tri-Gloss Meter. Uniform films were described as “pass”. The formulations and results are summarized in Table 1.
The results show better compatibility in the system when the Carbinol Fluid was used as the wetting agent. The films based on the Carbinol fluid were uniform and had the highest gloss values.
Other variations may be made in compounds, compositions, and methods described herein without departing from the essential features of the invention. The embodiments of the invention specifically illustrated herein are exemplary only and not intended as limitations on their scope except as defined in the appended claims.
