Description

Title of the invention: COSMETIC COMPOSITION COMPRISING ETHOXYLATED MATERIALS FOR IMPROVING THE PHYSICAL STABILITY OF POLYMER EMULSIONS FIELD OF THE INVENTION

[0001] The present invention generally relates to a fluid emulsion cosmetic composition and a method of making the same for providing benefits to the skin of a user, the fluid emulsion cosmetic composition comprising a combination of water-soluble and oil-soluble actives in a fluid emulsion to provide benefits to the skin of the user and exhibit a favorable textural aesthetic that is stable upon emulsion breakage in a lightweight texture that is not creamy or waxy. The benefits of the fluid emulsion cosmetic composition include, but are not limited to, the inclusion of >10% of a combination of water-soluble and oil-soluble actives without loss of physical stability. CONTEXT OF THE INVENTION

[0002] Cosmetic compositions in the form of emulsions that are stabilized only with polymers, as opposed to a combination of traditional emulsifiers and combined polymers, or traditional emulsifiers alone, can provide light, fluid, gel-like textures with greater ease and this type of feel is often well appreciated by many consumers. However, when oil-soluble actives are used in conjunction with water-soluble actives, an emulsion-like system is required rather than purely aqueous serum or gel-like components that cannot support the oil-soluble actives. There is therefore a need for sensory but stable emulsion-based serums that contain both water-soluble and oil-soluble actives.Many traditional emulsifiers are solid or waxy raw materials that need to be heated to melt during processing, expending considerable energy in the heating and cooling process. In addition, waxy emulsifiers often increase the viscosity and sensory creaminess or richness of the formula, which is not appropriate or desirable for consumers seeking lighter, less thick products such as toners, serums, and lotions. Unfortunately, without the use of traditional emulsifiers, emulsion stability is difficult to achieve. Without an emulsifier that can surround the entire oil phase and prevent . coalescence of the emulsion, the only raw material present to prevent instability is the polymer itself, which may be insufficient. These polymers can emulsify or disperse the oil droplets in a gel-like matrix.

[0003] Thus, there is a need to provide a composition that includes raw materials that are not thick wax emulsifiers and that can improve the emulsion stability of polymer-stabilized formulas without significantly altering the feel or galenic (i.e., without transforming a serum into a lotion or cream) of the base formula.

[0004] This disclosure provides a composition that employs ethoxylated raw materials to increase the physical stability of polymer-stabilized emulsions. In addition, for reasons of naturalness and renewability, the fluid emulsion-type cosmetic composition is free of silicone. The absence of silicone provides the by-product benefit of allowing a greater extent and concentration of oil-soluble actives, including oil-soluble actives that have low solubility in pure silicones.

[0032] The present disclosure describes exemplary embodiments according to the general inventive concepts and is not intended to limit the scope of the invention in any way. Indeed, the invention as described in the specification is broader than, and not limited by, the exemplary embodiments presented herein, and the terms used herein have their full ordinary meaning. DETAILED DESCRIPTION OF THE INVENTION

[0033] In the context of the invention, a direct emulsion is an oil-in-water emulsion.

[0034] “Keratin substrate” and “keratin tissue” each include, but are not limited to, limit, skin, hair and nails.

[0035] “Natural” or “naturally occurring” as used herein means, and refers to, cosmetically acceptable materials and components that are one or more of those directly obtained from nature, that are obtained from nature with minimal processing, and that are derivatives of materials that are obtained from nature. The fluid emulsion cosmetic composition according to the present disclosure is, in certain embodiments, up to 99.11% natural, or “highly natural” or “totally natural,” meaning that all carbon atoms of the intentionally added ingredients are derived from natural sources in accordance with ISO 16128.

[0036] “Skin” as used herein means and refers to cutaneous materials containing keratin such as facial and body skin, scalp, eyebrows and lips.

[0037] “Stable0” and “stability0” as used herein mean that the fluid emulsion-type cosmetic composition exhibits no evidence of significant changes in one or more of color, odor, pH, or viscosity, or emulsion breakdown / separation or excessive thickening into a creamy, waxy, or gel-like texture, aqueous texture, or gelation of the cosmetic composition, at room temperature and temperatures in the range of about 25°C to 45°C, and remains stable through freeze / thaw cycles of -20°C to 20°C for up to 10 days.

[0038] As used herein, the term “instability” refers to the inability of a composition to remain fluid or serum-like and demonstrates emulsion breakdown / separation or excessive thickening into a creamy, waxy, or gel-like texture, watery texture, or gelation of the cosmetic composition. Instability may occur in compositions made outside the scope of the disclosure (i.e., compositions not comprising the disclosed polymer and ethoxylated agents), and compositions including amounts of polymeric thickener greater than the amounts according to the disclosure, or conventional emulsifiers, thickeners and waxes.

[0039] The terms "exclude", "exempt" and "essentially exempt" mean that no reliably measurable excluded material is present in the fluid emulsion cosmetic composition, e.g., excluded gellan and waxes, vegetable butters, saturated alcohols / fatty acids above C16, silicones including silicone oils / emollients and silicone emulsifiers, including dimethicone, cyclomethicone, polysilicone-11, phenyltrimethicone, trimethylsilylamodimethicone, and stearoxytrimethylsilane, and other silicone oils, silicone emulsifiers and silicone elastomers, petrochemicals, including benzalkonium chloride, isododecane, isohexadecane, sulfate-based surfactants,emulsifiers selected from those with a hydrophobic substance of the alcohol or C10-C20 fatty acid type condensed with from about 2 to about 100 moles of ethylene oxide or propylene oxide per mole of hydrophobic substance, C2-C10 alkyl phenols condensed with 2 to 20 moles of alkylene oxide, ethylene glycol fatty acid monoesters and diesters, fatty acid monoglyceride, sorbitan, C8-C20 fatty acid mono- and di-acids, polyoxyethylene sorbitan, alkyl polyglycosides and fatty amide saccharides (e.g., methyl gluconamides), alkyl ether sulfates and sulfonates, alkyl sulfates and sulfonates, alkylbenzene sulfonates, alkyl and dialkyl sulfosuccinates, isethionates C8-C20 acyl, (C8-C20 alkyl)ether phosphates,alkyl ether carboxylate. Some specific emulsifiers that are missing from the composition include PEG-100 stearate; PEG-20 stearate and other poly(ethylene glycol) esters; sucrose stearate and other sugar ester emulsifiers, glyceryl stearate and other glycerol esters, disodium ethylene dicocamide PEG-15 disulfate; sodium stearoyl glutamate and other fatty amides; steareth-100 and other fatty ethers, or any other excluded material as described herein. The terms ““substantially free” mean that, although it is preferred that no excluded material be present in the fluid emulsion cosmetic composition, it is possible to have very small amounts of the excluded material in the fluid emulsion cosmetic composition of the invention,provided that such amounts do not materially affect the beneficial properties of the fluid emulsion cosmetic composition. In particular, “essentially free” means that the excluded material may be present in the fluid emulsion cosmetic composition in an amount of less than 5%, or less than , 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.1% by weight, relative to the total weight of the fluid emulsion type cosmetic composition.

[0040] As shown herein, the inventors have provided the fluid emulsion type cosmetic composition in the form of a direct oil-in-water emulsion which includes aqueous and oily phases and which includes at least one polymer or synthetic crosslinked polymer, at least one thickening polysaccharide, at least one ethoxylated agent having an HLB in a range of 8 to 14, at least one active selected from water-soluble skin care actives, oil-soluble skin care actives, and combinations thereof, water and at least one oil, the composition being free of silicones. The fluid emulsion-type cosmetic composition maintains a fluid texture that does not break, become creamy, waxy, or gel, including during freeze / thaw cycles, by maintaining a combination of water-soluble and oil-soluble actives present in an amount that is at least 10% by weight of the composition.

[0041] The fluid emulsion type cosmetic composition may also include one or more additional ingredients selected from, but not limited to, phenylethyl resorcinol, chelating agents, other skin active components, antimicrobials and preservatives, fillers, antioxidants, fragrances, pearlizing agents, odor absorbers, coloring materials, essential oils, vitamins and combinations thereof.

[0042] The inventors sought to develop a solution for stabilizing fluid emulsions, for example a fluid serum-like composition, which contains large amounts of oil-soluble and water-soluble actives (greater than or equal to 10%) without breaking the emulsion or without excessive and undesirable thickening or creaminess. The inventors surprisingly discovered that ethoxylated ingredients, including ethoxylated fatty alcohols and ethoxylated fatty acids, represent a class of raw materials (hereinafter referred to as "ethoxylated agents") which can offer the advantage of maintaining a fluid, serum-like consistency in the absence of silicones, with an additional benefit of allowing the incorporation of a wide range of actives (water-soluble and / or oil-soluble) which may have resistance to solubility in silicones.In general cosmetic arts, ethoxylated fatty alcohols and ethoxylated fatty acids are known as emulsifiers or solubilizers and are characterized by the presence of a hydrophobic alkyl acid / fatty alcohol moiety and a hydrophilic ethylene oxide moiety. Existing commercial products that include silicones or trace amounts of ethoxylated agents tend to have relatively small amounts of oil-soluble and water-soluble actives, and other products that include larger amounts. amounts of both water-soluble and oil-soluble actives are thick creams or gel creams that also contain waxy materials. The present invention addresses the need to provide a light, thin emulsion that includes large amounts of both water-soluble and oil-soluble actives and is stable under freeze / thaw conditions. The ethoxylated surfactant is believed to stabilize the oil phase with the polymeric thickening gum without further thickening, thereby preserving the thin, serum-like consistency of the emulsion. Specific examples of such ethoxylated agents, as shown in the examples, include laureth-4 and PEG-7 glyceryl cocoate.

[0043] The present invention describes a means of stabilizing a fluid polymer-stabilized, emulsion-based serum without adding a waxy characteristic or high viscosity by the choice of ethoxylated emulsifiers. Other polymers may be more electrolyte intolerant or thicken to add heaviness and body or thicken excessively to transform a light serum into a lotion or cream. I have identified the main attributes of MRs (liquid, HLB value, presence of ethoxylation) that provide good stability compared to other MRs that do not fall under these attributes. The ethoxylated emulsifiers have shown significantly improved freeze / thaw stability compared to the base and polyglyceryl type emulsifiers (as seen in microscope images).

[0044] Although it might be expected in the art that the HLB of a surfactant could be a primary factor in emulsion stability when all other ingredients are held constant, the inventors have unexpectedly discovered that this is not the case with respect to the composition of the present invention. As shown herein, laureth-4, PEG-7 glyceryl cocoate, and poly-glyceryl-6 dicaprate were all found to have very similar HLB values. However, only the former two showed a significant improvement in stability. Therefore, the HLB value is not the primary factor in stability, which is an unexpected attribute of this system. Furthermore, this can be done without the use of silicones (emollients or emulsifiers). This system can easily contain large amounts >10% of both water-soluble and oil-soluble actives without loss of physical stability.

[0045] The performance(s) of the composition of the invention compared to the reference index not having the claimed combination of ingredients are better than the reference index, including in terms of better stability compared to formulations which do not have ethoxylated emulsifiers, sensory improvement compared to formulations which would need to be stabilized using large amounts of polymer or with waxes, better durability compared to formulations which use silicones.

[0046] The cosmetic composition of fluid emulsion type is durable compared to lightweight silicone-containing serums, wherein in the composition of the invention, a low level (0.15%) of synthetic polymer is required, and the balance of the fluid emulsion-type cosmetic composition may include fully renewable and biodegradable components, including gum-type thickeners, actives, solvents, oils and other natural or naturally derived ingredients.

[0047] In accordance with the various embodiments, it is contemplated that some or all of the following ingredients may be excluded from the fluid emulsion cosmetic compositions used in accordance with the invention, namely: gellan, waxes, vegetable butters greater than about 5%, by weight, relative to the total weight of the fluid emulsion cosmetic composition, and saturated fatty acids / alcohols higher than C16 present in amounts greater than about 5%, by weight, relative to the total weight of the fluid emulsion cosmetic composition, and silicones including silicone oils / emollients and silicone emulsifiers. Other ingredients that may be excluded are petrochemicals and sulfate-based surfactants.

[0125] Example 3: Demonstration of the effect of ethoxylated agents compared to other emulsifiers on stability

[0126] To demonstrate the effect of ethoxylated agents on stability, a composition base (BASE) was prepared. This composition is an oil-in-water emulsion serum that contains 0.15% acrylates / C10-C30 alkyl acrylate crosslinked polymer as a stabilizing polymer, with xanthan gum as a thickener to increase viscosity. It also contains approximately 12% total actives, a penetration enhancer, preservatives, solvents, and 4% total oil phase. These ingredients all remain constant in all formulations tested for the effects of ethoxylated agents and other agents on stability, particularly freezing / thawing.

[0127] In this protocol, which represents potential conditions during shipping and storage, one ounce of each tested composition is placed in a jar that is placed in a chamber that cycles from -20°C to 20°C every 24 hours, and vice versa, and which are repeated daily. The samples are observed after 5 cycles (days) and 10 cycles (days). Notably, the base composition does not pass the freeze / thaw stability test.

[0128] From this BASE, 0.5% of each of the different emulsifiers was added to determine whether their addition improved stability. The examples are described below and correspond to the formulations shown in Table 2 above.

[0129] [Tables3] Tested composition BASE + HLB INV 1 0.5% laureth-4 10 INV 2 0.5% PEG-7 glyceryl cocoate 11 COMP 1 0.5% polyglyceryl-4 caprate 14 COMP 2 0.5% polyglyceryl-2 diisostearate 5 COMP 3 0.5% polyglyceryl-6 dicaprate 10 Tested formulations and HLB

[0130] Formulas INV 1 and INV 2 include ethoxylated agents, while the three comparators COMP 1, COMP 2 and COMP 3, include emulsifiers which are oligomeric in nature. They are formed using repeating units of glycerin, as opposed to repeating units of ethylene oxide.

[0131] All emulsifiers are liquid at room temperature; the composition can be manufactured without the addition of heat.

[0132] [Tables4] Formula Emulsifier RESULTS BASE Base; none Passed T0; instability increases over time; unacceptable at 5 days and 10 days INV 1 laureth-4 Passed all time points; no difference in emulsion quality INV 2 PEG-7 glyceryl cocoate Passed T0 and 5 days; less stable at 10 days but better than base and other formulations below COMP 1 poly-glyceryl-4 caprate Passed T0; instability increases over time; unacceptable at 5 days and 10 days Test result

[0133] The base with added ethoxylated agents showed a marked improvement in freeze / thaw stability compared to the base and polyglyceryl agents, as shown by microscope image analysis.

[0134] It was found that although laureth-4, PEG-7 glyceryl cocoate and poly-glyceryl-6 dicaprate all had very similar HLB values, only laureth-4 and PEG-7 glyceryl cocoate showed a large improvement in stability. Therefore, the HLB value is not the main factor in stability, which is an unexpected attribute of this system.

[0135] In accordance with certain embodiments, it is contemplated that some or all of the following ingredients may be excluded from the fluid emulsion cosmetic composition of the invention, namely: alcohols, for example, but not limited to, monohydric alcohols; powders comprising nylon-12, polymethyl methacrylate, polyethylene beads and powders considered microplastics; lactic acid, glycolic acid, tartaric acid, mandelic acid, citric acid, salicylic acid and derivatives thereof (including 5-n-octanoylsalicylic acid, salicylate, sodium salicylate and willow extract), capryloyl salicylic acid, beta-hydroxybutanoic acid, pro-pionic acid, beta-hydroxy beta-methylbutyric acid, carnitine tropic acid and trethocanic acid;alkyl polyglucosides selected from the group consisting of decyl glucoside, lauryl glucoside, octyl glucoside, coco glucoside, caprylyl / capryl glucoside, sodium lauryl glucose carboxylate, and combinations thereof; surfactants with a C10-C20 fatty alcohol or an acid hydrophobe condensed with from about 2 to about 100 moles of ethylene oxide or propylene oxide per mole of hydrophobe; C2-C10 alkylphenols condensed with from 2 to 20 moles of alkylene oxide; mono- and di-fatty acid esters of ethylene glycol; fatty acid monoglyceride; sorbitan; mono- and di-fatty acids of C8-C20; polyoxyethylene sorbitan; alkyl polyglycosides and fatty amides of saccharide (e.g., methyl gluconamides); alkyl ether sulfates and sulfonates; alkyl sulfates and sulfonates; alkylbenzene sulfonates; alkyl and dialkyl sulfosuccinates; C8-C20 acylisethionates; C8-C20 alkyl ether phosphates; alkyl ether carboxylate, alkyl ether, PEG-100 stearate;PEG-20 stearate and other poly(ethylene glycol) esters; polyethylene glycol (PEG) surfactants, polypropylene glycol (PPG) surfactants, sulfate surfactants, e.g., taurate surfactants; sucrose stearate and other sugar ester emulsifiers; glyceryl stearate and other glycerol esters; disodium PEG-15 ethylene dicocamide disulfate; sodium stearoyl glutamate and other fatty amides; steareth-100 and other fatty ethers, cationic surfactants and other cationic compounds; silicones, such as silicone polymers, silicone elastomers and silicone oils, for example chosen from dimethicone, cyclomethicone, polysilicone-11, phenyl trimethicone, trimethylsilyl amodimethicone, stearoxytrimethylsilane, cyclopentasiloxane, cyclohexasiloxane and combinations thereof;phthalates, parabens, sulfates, polyquaternium-7, microplastics, synthetic colorants, gelling agents and related combinations.
