Substituted hydrocarbyl functional siloxanes for household, health, and personal care applications

FIELD OF THE INVENTION

[0002] The present invention relates to cosmetic, household and healthcare compositions containing a hydrocarbyl functional organopolysiloxane. 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 inclusion of the hydrocarbyl functional organopolysiloxane results in personal, medical and household care compositions with improved performance and/or stability.

BACKGROUND OF THE INVENTION

[0003] In the household, health and personal care areas, the need exists for silicone raw materials that contain both hydrophilic and hydrophobic functionality. To date, this need has been addressed with polyoxyalkylene and silanol functional silicone materials. In particular, there are numerous examples of the use of polyoxyalkylene functional silicones, also referred in the art as silicone polyethers and/or silicone glycols, in various personal, household, and healthcare applications.

[0004] Majority of the oxyalkylene functional silicones used in various personal, household, and healthcare applications contain polyoxyalkylene moieties, that is having multiple oxyalkylene units. This is most likely because of two reasons. First, majority of these oxyalkylene functional silicones have been used as surfactants in such applications. As analogous to hydrocarbon based polyoxyalkylene surfactants, multiple oxyalkylene units are needed to impart sufficient hydrophilicity for surfactant character. The amount of oxyalkylene units present in such surfactant molecules is often depicted as a HLB (hydro-lipophilic balance) value. Thus, polyoxyalkylene functional silicones with varying HLB's have found use in various personal, household, and healthcare applications where they function as surfactants and emulsifiers.

[0005] Secondly, the majority of the oxyalkylene functional silicones used in various personal, household, and healthcare applications contain polyoxyalkylene moieties because of the ready availability of the starting materials and synthetic ease of making allyloxypolyethers with that minimum substitution. Polyoxyalkylene functional silicones are usually prepared by hydrosilylation of an organohydrogensiloxane (SiH) and an olefinically substituted polyoxyalkylene. For example, the platinum catalyzed reaction of Si—H polymers with allyl ethers was disclosed in U.S. Pat. No. 2,823,218 (Feb. 11, 1958). Typically, the smallest oxyalkylene substitutents used in such applications are EO4 and PO2. This is because of the ready availability of the starting materials and synthetic ease of making allyloxypolyethers with that minimum substitution.

[0006] U.S. Pat. Nos. 5,486,566 and 6,060,044 provide representative examples of the use of polyoxyalkylene functional silicones in various personal care formulations. The '566 patent describes siloxane gels for use in various personal care applications. The gel contains an amide-free gelator, a siloxane polyether for strengthening the gel, and a volatile methyl siloxane. While the '566 teaches the use of both oxyethylene units —(C2H4O)p— and oxypropylene units —(C3H6O)s— for the polyether segments of the siloxane polyether, the oxypropylene based polyethers are preferred. U.S. Pat. No. 6,060,044 describes a cosmetic composition comprising in a cosmetically acceptable medium, at least one guar gum and at least one oxyalkylenated silicone in a guar gum/silicone weight ratio of less than or equal to 5:1.

[0007] Many of the existing polyoxyalkylene and silanol functional silicones possess inherent properties that limit their use in many household, health and personal care formulations. For example, existing polyoxyalkylene and silanol functional silicones have unpleasant aesthetics upon skin application from a formulation. Furthermore, many have limited stability in acid or basic formulations. Thus, there is a need for silicones having both polar and non-polar characteristics yet provide good aesthetics upon skin application and that are also stable in acidic and basic formulations.

[0008] The present inventors have discovered that the inclusion of a hydrocarbyl functional organopolysiloxane, in particular where the hydrocarbyl group has the formula—R2OCH2CH2OH, where R2 is a divalent hydrocarbon group containing 2 to 6 carbon atoms, results in personal care, medical and household care compositions with unique properties. In particular, the hydrocarbyl functional organopolysiloxanes are stable in acidic and basic formulations, and provide good aesthetics upon skin application.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The hydrocarbyl functional organopolysiloxane of the present invention comprises a siloxy unit of the formula R1 RaSiO(3-a)/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, a is zero to 2.

[0017] 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—.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] In one embodiment, the hydrocarbyl functional organopolysiloxane has a formula selected from the group:

[0022] R3SiO(RR1SiO)ySiR3,

[0023] R3SiO(R2SiO)x(RR1SiO)ySiR3,

[0024] R1R2SiO(R2SiO)xSiR2R1,

[0025] R1R2SiO(RR1SiO)zSiR2R1,

[0026] R1R2SiO(R2SiO)x(RR1SiO)zSiR2R1,

[0027] R1R2SiO(R2SiO)xSiR3,

[0028] R1R2SiO(RR1SiO)zSiR3,

[0029] R1R2SiO(R2SiO)x(RR1SiO)zSiR3, and cyclic siloxanes of the formula

[0030] —(Me2SiO)m(MeR1SiO)n—.

[0031] 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.

[0032] 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

[0033] 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.

[0034] In a preferred embodiment, the hydrocarbyl functional organopolysiloxane has the formula

R1Me2SiO(Me2SiO)xSiMe2R1

[0035] where R1 is —(CH2)3OCH2CH2OH and x is 1 to 100, alternatively 5 to 50, or alternatively 10 to 20.

[0036] 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.

[0037] The present invention is based on the unexpected discovery that the inclusion of the hydrocarbyl functional organopolysiloxane, in particular, results in personal care, medical and household care compositions with unique properties. For example, compositions containing the hydrocarbyl functional organopolysiloxane impart the following characteristics when compared to similar formulations without such siloxanes: (a) remain stable at relatively high and low pH; (b) compatibilize both polar and non-polar solvents; (c) offer high lubricity; (d) mitigate skin discomfort or irritation; (e) impart a smooth, soft, moist texture; (f) evenly disperse active agents and pigments; (g) detackify formulation components; (h) moisturize the skin; (i) enhance the durability of formulation components; (j) enhance surface shine; (k) impart the sensory performance of higher molecular weight structures; (l) protect the hair cuticle; (m) aid curl retention; (n) sustain fragrance release; (o) impart softness to solid substrates; (p) increase water absorbency of fabrics; (q) mask surface imperfections; (r) reduce whitening of antiperspirant salts; (s) modify formulation rheology; (t) improve particulate active suspension; (u) improve ease of ironing; (v) enable the suspension and delivery of polar materials in non-polar solvents; and (w) enhance emulsion stability.

[0038] 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.

[0039] The hydrocarbyl functional organopolysiloxanes are useful in a number of different products, including hair care products such as hairsprays, shampoos, mousses, styling gels and lotions, cream rinses/conditioners, hair tonics, hair dyes and colorants, permanent waves and bleaches. Also included are skin care products such as cleansers, moisturizers, conditioners, lipsticks, eye makeup, foundations, fingernail polish, suntan products, antiperspirant/deodorant products and depilatories. Also included are household products such as waxes, polishes, heavy and light duty liquid cleaners, fabric softeners, ironing aids, laundry detergents, and window cleaners.

[0040] 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 (Laureth4); 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.

[0041] 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.

[0042] 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.

[0043] 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).

[0044] 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.

[0045] 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.

[0046] Some of the typical active ingredients used in products such as these are antiacne agents, anticaries agents, antidandruff agents, antifungal agents, antimicrobial agents, antioxidants, antiperspirant agents and deodorant agents, cosmetic biocides, external analgesics, oral care agents, oral care drugs, oxidizing agents, reducing agents, skin bleaching agents, skin protectants, sunscreen agents, UV light absorbing agents, enzymes, optical brighteners, fabric softening agents, and surfactants
