Bitler). The entire disclosure of each of these United States patents and patent application is incorporated in this specification by reference.
The entire disclosure of the previously identified patents, and patent applications is incorporated herein by reference for all purposes.
In accordance with certain aspects of the present invention, a broad range of functionalized side chain crystalline (SCC) polymers can be used to thicken oils, provided that the SCC polymer will dissolve in the oil at a temperature above the crystalline melting point of the polymer (referred to herein as Tp) and can crystallize when the solution of the polymer in the oil is cooled to a temperature which is below Tp and at which the thickened oil composition is to be used. Without wishing to be bound by any theory or explanation, it is believed that the SCC polymer crystallizes into a network in which the polymer crystallites are connected to one another by semi-soluble chains.
In one aspect of the invention, the invention provides a personal care composition and method for making and using the composition wherein the SCC polymer has at least one functionality selected from the group consisting of silicone, hydroxyl and carboxy. Such functionalized SCC polymers can be employed in a wide range of personal care compositions including skin care, body wash, shampoo, hair styling and hair treatments (e.g., hair molding cream, combing cream and pomade, hair sprays, hair colorant), sunscreen, lipstick, anti-perspirant, deodorant, shaving and after shaving products and among other personal care products. The amount of SCC polymer is sufficient to thicken, modify rheology, film form, enhance aesthetics, or improve sensory and feel, especially silicone, among other benefits.
In another aspect, this invention provides a method of making a composition, the method comprising
In a further aspect of the invention, an advantage of using these SCC polymers as thickening agents, particularly in water-in-oil emulsions, water-in-silicone, silicone-in-water or multi-phase emulsions, for example, water/oil/water or oil/water/oil, are that the need to use a surface active agent and any other water or oil phase thickener or rheology modifier other than SCC is reduced or removed. Thus the compositions can contain less than 5%, typically less than 2%, usually less than 1%, and in some cases about 0%, of surface active agents or other oil phase or water phase thickeners or rheology modifiers, the percentages being by weight based on the weight of the oil. This is particularly useful in cosmetic and personal care products, since it is conventional for such products to contain surface active agents (for example, perfluoroalkyl organic compounds), and surface active agents can cause an adverse reaction when they contact human skin.
In the Summary of the Invention above, and in the Detailed Description of the Invention, the Examples, and the Claims below, reference is made to particular aspects of the invention. It is to be understood that the disclosure of the invention in this specification includes all appropriate combinations of such particular features. For example, where a particular aspect or feature is disclosed in the context of a particular embodiment or a particular claim, that feature can also be used, to the extent appropriate, in the context of other particular embodiments and claims, and in the invention generally.
The invention is particularly useful for personal care compositions, for example cosmetics, toiletries, and cleansers, including but not limited to lipsticks, deodorant sticks, nail varnishes, creams, gels and oils, including sunscreen, hand protective products, night renewal products, body milks, creams and lotions, light facial products, protective day care products, liquid moisturizing emulsions, oil-in-water and water-in-oil creams, as well as thickened oil products with or without water and products designed to assist in removing other cosmetic, makeup or personal care products. The invention is also useful in other contexts, for example in paints, film-forming compositions, inks, and compositions carrying active ingredients such as UV absorbers, fragrances, antimicrobial agents, germicides, antioxidants, preservatives, enzymes, nutrients, minerals and if desired, the foregoing can be supplied in a controlled-release format.
The instant invention can employ at least one of functionalized side chain crystalline polymers (FSCC) and side chain crystalline polymers (SCC) to obtain improved cosmetic or personal care formulations. Non-limiting examples of such polymers comprise at least one member selected from the group consisting of Poly C12-22 AlkylAcrylates/Methacrylic Acid Crosspolymer (Intelimer® 8600, Intelimer® 8100), Poly C10-30 alkyl acrylate (Intelimer® IPA 13-1, Intelimer® IPA 13-6), Poly C12-22 Alkyl Acrylates/Hydroxyethylacrylate Copolymer (Intelimer® 1261, Intelimer® 1266), Poly C8-22 Alkyl Acrylates/Butyl Dimethicone Methacrylate Copolymer (Intelimer® 1221, Intelimer® 1226), and Poly Acrylic Acid/C8-22 Alkyl Acrylate Copolymer (Intelimer® 1281, Intelimer® 1286). The following are examples of some of the benefits that can be obtained by using the FSCC and/or SCC polymers:
In this specification, parts and percentages are by weight, except where otherwise noted. Temperatures are in ° C. The onset-of-melting temperature, To, the peak melting temperature, Tp, and the heat of fusion, J/g, are determined using a differential scanning calorimeter (DSC) at a rate of temperature change of 10° C./min, for example from −10 to 150° C., and on the second heat cycle. Tp is the temperature at the peak of the DSC curve, and To is the temperature at the intersection of the baseline of the DSC peak and the onset line, the onset line being defined as the tangent to the steepest part of the DSC curve below Tp. The abbreviations Mn and Mw are used to denote number average and weight average molecular weight in daltons, respectively, measured in tetrahydrofuran using size exclusion chromatography, configured with a Wyatt laser light scattering detector. Bulk viscosities given in the Examples for the polymeric thickeners are in centipoise and were measured using a Brookfield LVT viscometer with an electrically thermostatted Thermosel heater, controlled for example to 95° C., and small sample adapter using spindles 4 and 7. Wt % or % w/w refers to weight percent; and q.s. means to incorporate an amount of the indicated material sufficient to make the sum of all % w/w equal to 100
The abbreviation CxA is used to denote an n-alkyl acrylate in which the n-alkyl group contains x carbon atoms, the abbreviation Cx alkyl is used to denote an n-alkyl group which contains x carbon atoms, and the abbreviation CxM is used to denote an n-alkyl methacrylate in which the n-alkyl group contains x carbon atoms. Other abbreviations are given elsewhere in the specification.
The FSCC and/or SCC polymers used as thickeners in the present invention can be homopolymers, or copolymers of two or more comonomers, including random copolymers, graft copolymers and block copolymers (including thermoplastic elastomers). Two or more SCC polymers can be used together. The number average molecular weight of the SCC polymer is generally from about 10,000 to about 1,500,000, normally 12,000 to 1,000,000. The molecular weight of an SCC polymer is relatively unimportant to its Tp, but is generally an important factor in determining the Tp of other polymers.
The SCC polymer usually melts over a relatively small temperature range. The closer Tp is to room temperature, in general the more rapid the transition. The SCC polymer normally has an onset of melting temperature, To, such that Tp−To is less than Tp0.7, generally less than Tp0.6, particularly less than 10° C., especially less than 6° C., To and Tp being in ° C. The crystallinity of the SCC polymer is typically such that its heat of fusion is at least 20 J/g, particularly at least 40 J/g.
The SCC polymer may for example be derived from one or more acrylic, methacrylic, olefinic, epoxy, vinyl, ester-containing, amide-containing or ether-containing monomers. SCC polymers can comprise repeating units in which the side chains comprise linear polymethylene radicals containing 10 to 50, e.g. 16-50, especially 16 to 22, carbon atoms. Polymers containing such units can be prepared by polymerizing a monomer component comprising one or more corresponding linear aliphatic acrylates or methacrylates, or equivalent monomers such as acrylamides or methacrylamides. A number of such monomers are available commercially, either as individual monomers or as mixtures of identified monomers, for example C12A, C14A, C16A, C18A, C22A, a mixture of C18A, C20A and C22A, and a mixture of C26A to C40A. The polymers may also contain units derived from one or more other comonomers, for example straight or branched chain alkyl acrylates or methacrylates in which the alkyl group contains less than 12 carbon atoms, and monomers containing suitable functional groups, for example functional groups comprising at least one member selected from the group consisting of oxygen-, nitrogen- or silicon-containing, carboxy- or hydroxyl-groups, cationic functionality (quaternized compounds such as those containing nitrogen) dimethyl amines (e.g. arylamide), among other functionality. Such monomers include, for example, those listed below. In the list below, the term (meth)acrylate means that the compound may be either an acrylate or a methacrylate:
When the SCC polymer comprises a graft or block copolymer, it can be prepared by copolymerizing a vinyl type macromonomer with other monomers, or by making an SCC polymer, and then reacting the functionalized polymer with the second block material, for example a urethane block, an epoxy block, a polyether block, e.g. a polyethyleneoxide, polypropyleneoxide or polytetramethyleneoxide block, a polysiloxane block, or a poly(alkyl or alkoxy)silane block, or it can be prepared by using any other suitable method of polymerization such as emulsion or suspension polymerization in the presence of surface active agents and/or colloids, or bulk polymerization or solution polymerization. Non-limiting examples of surface active agents comprise at least one member of cetearth, laureth, pareth, PEG and/or PPG or POE esters and ethers of sorbitan Oleate, octyl phenyl and/or ester of nonylphenyl and sulfosuccinate, sodium or Disodium salts like Disodium C-isodecylslfosuccinate, sodium isostearate, esters or ethers of natural and synthetic oils and waxes like PEG and/or PPG hydrogenated caster oils, among others. Non-limiting examples of colloids comprise at least one member of stearyl alcohols; behenyl alcohols; modified and unmodified gums like cargeenans, celluloses, carbomers; PVP; Hydrogenated and hydrolyzed waxes and/or oils; among others.
The SCC polymer can contain sufficient long chain groups that it will dissolve in the oil at a temperature above Tp. When the SCC polymer is used to thicken an oil or a mixture of oils which is free from water, the polymer generally contains at least about 50%, normally at least about 60%, particularly at least about 70%, especially at about least 80%, of units comprising a linear radical containing about 10 to about 50 carbon atoms, and can contain up to 100% of such units. Particularly when the SCC polymer is used to thicken a water-in-oil or water-in-Silicone or multiple-phase emulsion, it may contain at least about 5%, usually at least 10%, of units derived from a monomer containing a functional group, such as at least one of hydroxyl, COOH and silicone functional groups and may contain higher amounts (e.g. up to 25% or 30 wt %), provided that the SCC polymer will at least partially dissolve in the oil.
In one aspect of the invention, the SCC polymer consists essentially of
Suitable polymers within the foregoing aspect can include SCC polymers consisting essentially of
In another aspect of the invention, the SCC polymer consists essentially of
Suitable polymers within the foregoing aspect can include SCC polymers consisting essentially of
In a further aspect of the invention, the SCC polymer consists essentially of
Suitable polymers within the foregoing aspect can include SCC polymers consisting essentially of
The molecular weight and other properties of the SCC polymer can be sufficiently controlled such that the polymer, after it has been dissolved in the oil, will crystallize in the oil when the heated mixture is cooled to the expected temperature of use, for example to a temperature 10-20° C. below Tp, thus producing an opaque or clear mixture.
The Tp of the thickening polymer is normally 10-40° C. above, particularly 10-30° C. above, especially about 20° C. above, the temperature at which the composition is to be used, which is generally 15-40° C. It appears that the oil plasticizes the thickening polymer, so that its melting point in the composition is for example 5-20° C. lower than Tp. It is therefore desirable that Tp is sufficiently above the temperature of use to ensure that the thickening polymer does not melt during use. Thus for compositions to be used at around 20-35° C. the thickening polymer can have a Tp of above 40° C., usually 40-70° C. On the other hand, if the Tp of the thickening polymer is too far above the temperature of use, this can result in excessive crystallization and then precipitation of the polymer, thus reducing the thickening effect. It is useful, therefore, that Tp is not more than about 30° C. above, usually not more than 20° C. above, the temperature of use. Depending on the expected temperature of use, Tp may be from 0-150° C., generally 10-100° C., typically 40-70° C., particularly 43-55° C.
The amount of the polymeric thickener used may vary with the application. It is usually unnecessary for the amount of the thickener to be more than about 10% by weight based on the weight of the oil. Smaller amounts such as about 2 to about 7% based on the weight of the oil in compositions which are free of water, and about 0.5 to about 5% based on the weight of composition in water-in-oil, water-in-silicone or multiple phase emulsions, are often effective. In one aspect of the invention, the amount of polymeric thickener is sufficient to form an emulsion (e.g., a water in oil, or an oil in water emulsion), having enhanced rheology and sensory properties. These properties can provide a sunscreen skin care emulsion having enhanced film building properties upon the skin and in turn increase the SPF of the sunscreen.
In another aspect of the invention, the amount of polymeric thickener is tailored to impart enhanced water/moisture and rub-off resistance to a cosmetic composition.
In a further aspect of the invention, the amount of polymeric thickener is tailored to impart increased moisture retention or occlusivity of a cosmetic skin care product.
In another aspect of the invention, the amount of polymeric thickener is sufficient to impart enhanced or controlled release of an active ingredient of a cosmetic composition, for example, by incorporating actives in the cosmetic media into amorphous crystalline matrix structure and releasing the actives in controlled manner at or near to body temperature. For example, the inventive composition can comprise an FSCC and/or SCC polymer containing antiperspirant or deodorant composition, or the composition can comprise one or actives such as sunscreen actives or salysalic acid or any other cosmetic/personal care active used in anhydrous or emulsion formulations.
The functionalized polymeric thickeners are effective with a broad range of oils such as at least one member selected from the group consisting of esters (C12-15 Alkyl benzoate), triglyceride (Caprylic/Caprylate triglyceride) hydrocarbons (mineral oil, sunflower oil) natural oils (jojoba oil, safflower oil) castor oil, among others. Suitable oils are also disclosed, for example, at column 3, line 37, to column 4, line 4, of U.S. Pat. No. 5,736,125; hereby incorporated by reference. For thickening silicone oils, it is useful to use an SCC polymer containing units derived from a monomer containing silicon, for example a block copolymer containing SCC blocks and polysiloxane blocks.
SCC/polysiloxane polymers of this type are described for example in WO 93/07194 and WO 00/04787; hereby incorporated by reference. Non-limiting examples of silicone oils can comprise at least one of dimethicone, pdms, organo silicone oils, dimethicones and cyclomethiconesln one aspect of the invention, the SCC polymers are employed as rhelogy modifiers (e.g., thickener) for at least one of dimethicone, cyclomethicone, and other low viscosity silicone oils.
In one aspect of the invention, thickened oils with functionalized SCC provide a cosmetic formulation having unique aesthetic benefits (e.g., texture and feel). In some cases, the functionalized SCC and be combined with one or more SCC polymers. The ratio of SCC to functionalized SCC can range from about 0:1 to about 10:1. The following are non-limiting examples of cosmetic formulations containing thickened oils having such benefits:
If desired, the color cosmetic is thickened only with at least one of FSCC and SCC polymers. If desired, however, conventional thickeners such as waxes like Carnauba wax, Bees wax, Candellila wax, among others can employed along with the FSCC and SCC polymers.
Water-in-oil emulsions are typically prepared by mixing together (1) a hot solution of the thickener in the oil and (2) the aqueous phase, the aqueous phase being at a temperature similar to the oil solution (e.g. not more than 10° C. different); and then cooling the mixture while stirring. The ratio of the aqueous phase to the oil phase can be, for example, about 0.5:1 to about 9:1.
One aspect of the invention, relates to using at least one of SCC and functionalized SCC polymers to prepare a water-in-oil emulsion. When employing SCC and functionalized SCC, the ratio of SCC to functionalized SCC can range from about 0:1 to about 10:1 The following are non-limiting examples of cosmetic formulations comprising water-in-oil emulsions:
Oil-in-water emulsions are typically prepared by mixing together an oil phase into a water phase. The ratio of the Oil phase to the water phase can be, for example, about 0.1:1 to about 1:1.

The following are non-limiting examples of cosmetic formulations comprising oil-in-water emulsions:
The previously described water-in-oil and oil-in-water emulsions can be used to prepare a multiple phase emulsion (e.g. water/oil/water, or oil/water/oil). Multiple phase emulsions can also be prepared by combining the previously described water-in-oil or oil-in-water emulsions with at least one of SCC or FSCC, where the SCC or FSCC is in an emulsion or suspension form (e.g., emulsified Poly C12-22 AlkylAcrylates/Methacrylic Acid Crosspolymer).
One aspect of the invention, relates to using at least one of functionalized SCC and SCC polymers to prepare an alcohol or aqueous systems including emulsion. When employing functionalized SCC and SCC, the ratio of SCC to functionalized SCC can range from about 0:1 to about 10:1. These polymers can be used to thicken the alcohol or aqueous systems, as well as to provide benefits of film forming, controlled delivery or deposition of actives, and fragrance or volatiles retention. The following are non-limiting examples of cosmetic formulations comprising alcohol or aqueous systems:
Alcohol or Aqueous system with at least one of FSCC and/or SCC polymers:
If desired, one or more properties of a cosmetic composition can be controlled by adding a plasticizing compound to the composition. Examples of such compounds comprise at least one member selected from the group consisting of silicone based plasticiziers, natural or synthetic compounds (e.g., polysaccharides, natural or synthetic Gums, stabilizers, anionic and nonionic associative thickener or rheology modifiers soluble in oil or water phase), other film forming polymers like polyurethanes, pyrolidines (e.g., polyvinylpyrolidine), among other compounds In one aspect of the invention, the additives comprise at least one member selected from the group consisting of preservatives, stabilizers (e.g., Xanthan Gum), humectant (e.g., at least one of Glycerine, MP Diol, Sorbitol, and Hexylene Glycol), antioxidant (e.g., Vitamins), rheology modifiers, fragrances, pigments, among other additives.

Examples of such active compounds comprise at least one member selected from the group consisting of sunscreen active (zinc oxide, titanium dioxide, octinoxate, octocrylene, ethylhexyl Salicylate, oxybenzone, among others); Skin whitener (salicylic acid, among others); APDO actives (aluminum chlorohydrate, aluminum zirconium tetra chlorohydrex, among others), Vitamins (Tocopherol natural, Synthetic Tocopherol, Synthetic tocopherol acetate, Retinol, Retinyl palmitate, acetate, Provitamin B-5, Ascorbic acid, Sodium ascorbyl phosphate, Ascorbyl glucoside, Magnesium ascorbyl phosphate, among others); Polysaccharides (Hyaluronic acid, B-1,3-glucans, Chitosan, among others); Botanicals (Aloe vera, Green tea extract, Grape seed extract, Isoflavones, Chamomille/bisabolol, Fennel, Ginko, Ginseng, Guava, among others); Alpha Hydroxy Acids (Citric acid, Glycoloc acid, Lactic acid, among others), Sugar cane extracts; Coenzymes and Enzymes (Ubiquinone, Coenzyme Q10, among others); and cosmeceuticals, among other active ingredients
One aspect of the invention comprises a method for using the inventive compositions to control the rate at which active compounds are provided. The rate can be controlled to be faster or slower than that possible without the inventive compositions.
For example, the inventive compositions can be used for controlling the delivery rate of at least one of the following sunscreen actives (e.g., organic or inorganic), antiperspirant (e.g., aluminum APDO emulsion and stick), cosmeceutical compounds, antimicrobial compounds, among other compounds wherein controlled release is desirable. Another aspect of the invention relates to controlling the deposition or release of compounds such as relatively volatile compounds (e.g., fragrances), colorants (e.g., a coloring shampoo), among other compounds wherein it is desirable to control their deposition, delivery and/or release.
Certain aspects of the instant invention are illustrated by the following non-limiting Examples. The procedures used in the Examples to compare the effectiveness of the polymeric thickeners were as follows. In Examples 1-6, the thickener, 5 parts, was dissolved in hydrogenated polyisobutylene (HPIB, light oil), 95 parts, with stirring at 120° C. The resulting solution was placed in an incubator at 20° C. for 16 hours. The viscosity of the cooled product in centipoise was determined using a Brookfield DV-I+ digital viscometer with CP-51 spindle using a sample adapter which was thermostatically controlled, for example, to 25° C. The viscosities were measured after four minutes at a speed of 2.5 rpm, i.e. after 10 revolutions. In Examples 7-12, the oil (as identified in Table 2), 14 parts, was heated to 80° C., and the thickener, 0.75 parts, was dissolved therein. Water, 35 parts, containing MgSO4.H2O, 0.25 part, was heated to 80° C. The oil and the water, both at 80° C., were mixed together, and then cooled to 25° C. with continued stirring. The product, a milky white water-in-oil emulsion, was left overnight, and its viscosity at 25° C. was then measured using a Brookfield cone and plate viscometer. The viscosity was measured after 0.5, 1, 2 and 4 minutes, to assess the effect of shear on the emulsion.
The remaining Examples illustrate formulations of compositions incorporating functionalized SCC and/or SCC polymers. These Examples illustrate personal care formulations comprising skin care creams, lotions, and sun screens, body cleansing compositions (e.g., shower mouse), hair care (e.g., hair styling and conditioning), among other formulations.
Polymers and copolymers were made using the ingredients and amounts thereof shown in the Table below, using the following generalized method. To a resin kettle equipped with overhead stirrer and condenser was added 20% of the monomers and chain transfer agents. The mixture in the resin kettle was heated to 110° C., and oxygen was removed from the system through nitrogen purge for about 30 min followed by addition of 20% of the starting initiator charge. After allowing sufficient time for any initial exotherm to abate, the remaining monomers, chain transfer agents and starting initiator were pumped into the reaction vessel over 60-90 min. The polymer mixture was allowed to continue reacting for 60 min followed by addition of the chase initiator and reaction for 60 min. The mixture was put under reduced pressure for 60 min to remove volatile residuals. The resulting polymers were generally yellow to white solids. The molecular weight, Tp, and viscosity of each sample were measured. The effectiveness of the polymers as thickeners was measured as described above, and the results are shown in Tables 1 and 2 below.
The following abbreviations are used in the Tables. ME=mercaptoethanol; MA=methacrylic acid; DMAEA=N,N-dimethylaminoethyl acrylate; HEA=2-hydroxyethyl acrylate; TAPO=t-amylperoxy 2-ethylhexanoate sold by Witco as Esperox 570P, 75% active in liquid; TBPB=t-butylperoxybenzoate sold by Witco as Esperox 10; Estol is propylene glycol dicaprylate/caprate sold by Uniqema under the tradename Estol 1526; Min'l is mineral oil; and opq=opaque in appearance.
In Example 2, within the HPIB oil the polymer had a Tp above a desirable range, which resulted in excessive crystallinity and poor thickening under the test conditions. However, in other oils (e.g. isopropyl palmitate, or isopropyl myristate) sufficient plasticization of Tp for the polymer of Example 2 may still result in effective thickening. In Example 4, within the HPIB oil the polymer had a Tp below the desired range, and was ineffective as a thickener under the test conditions, because it did not crystallize on cooling. However, the polymer of Example 4 could still provide thickening or film forming benefits within an oil where little plasticization occurred (e.g. mineral oil, or ethanol).
