RELATED APPLICATIONS

[0001] This application claims the benefit of, and priority to, US Patent Application Serial No. 17/560,328, filed on December 23, 2021, entitled CREAMY HYDRATING COSMETIC COMPOSITION IN A WATER RELEASE EMULSION, as well as French Application No. 2201205, filed on February 11, 2022, the entirety of which are incorporated by reference herein.

FIELD

[0002] This invention relates to a cosmetic composition, in particular a creamy water in oil emulsion that exhibits a fast, watery break during application.

BACKGROUND

[0003] Consumers seek cosmetic compositions that are formulated with sustainable, natural and/or green materials, and in particular that lack or minimize use of non-renewable ingredients (e.g., mineral oil and petrol based ingredients) and ingredients that have negative environmental impact. In some examples, consumers seek such compositions that also provide hydrating and moisturizing benefits with a pleasing texture, such as hydrating and moisturizing products that include high water content in an inverse or water in oil emulsion. A variety of products are available that include at least some of the desirable features sought by consumers, however, formulations that include high water content in an inverse or water in oil emulsion have been shown to be unstable for conventional use and storage, owing to the limitations of the emulsifier systems employed to retain the water phase in the oil phase. Thus, despite their otherwise desirable properties, such products may fail to meet the quality expectations of customers when the products break prior (i.e., release water phase from the oil phase and convert from a thick and creamy to a liquidous state) prior to application losing their thick and creamy texture and become thin and liquidous or leaving pools of water and/or oil phase in the container. Accordingly, there is a need for products that provide the environmental and sensorial properties that customers seek and maintain stability of texture during storage and under conditions of ordinary use. SUMMARY

[0029] These and other aspects of the invention are set out in the appended claims and described in greater detail in the detailed description of the invention.

[0030] This disclosure describes exemplary embodiments in accordance with 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 unlimited by the exemplary embodiments set forth herein, and the terms used herein have their full ordinary meaning. [0031] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

DETAILED DESCRIPTION

[0032] The term "break" as used herein refers to the phenomenon of release of the water phase from the oil phase in an inverse (water-in-oil) emulsion and conversion of the emulsion from a thick and creamy to a liquidous state. Breaking is demonstrated and may be measured based on one or more of the extent of release of water phase from the emulsion as detected visually or by measuring the quantity of released water phase, and the change in the fluid properties of the emulsion, either as detected visually/tactically as a change from more solid like cream to liquid, or rheological measurement. The term "break point" refers to a measurable point at which breaking occurs upon the application of a rubbing force, and in some instances, application of a measurable strain using a testing instrument. As described herein, the break point of an inventive composition may be selected based on the amount of the at least one diol present where increased amount of diol confers a faster break under the same rubbing or strain application as compared with a lesser amount of diol.

[0033] The terms "stable" and "stability" with respect to the emulsion architecture of the inventive composition refers to the composition remaining in a creamy emulsion state and not phase separating as evidenced by the formation of significant fluid droplets or pooling of separated phases (e.g., during storage and absent application of force or strain by rubbing on a substrate) and/or maintaining rheological characteristics over time. In some embodiments, stable or stability may include the absence of or minimal formation droplets which indicate release of the internal water phase from the emulsion. Stability is evidenced by one or both of visual inspection and by direct measurement of viscosity. In various embodiments, an inventive composition remains stable at temperatures in the range from about 5 °C to about 45 °C inclusive of the endpoints, over a time period of at least 8 weeks (~two months), and may remain stable for longer, for example for at least three months, or at least four months, or at least six months, and up to about at least 3 years, or any value, range, or sub-range therebetween. The exemplified embodiments of the inventive composition shown in the examples herein demonstrated stability at each of 5 °C, 25 °C, 37 °C, and 45 °C for a period of eight weeks. And such exemplified compositions demonstrated stability for 10 freeze-thaw cycles at -20 °C /25 °C.

[0034] The cosmetic composition of the present disclosure is in the form of a creamy emulsion having an internal water phase in an oil phase includes at least one polyglyceryl ester, a glutamic acid, or a derivative thereof, at least one cosmetically acceptable glycol or diol, at least one oil, water, and optionally one or more additives. A water-in-oil emulsion is sometimes referred to as a reverse emulsion. The composition is formulated as a "green" or more "nature-based" composition as compared with comparable compositions, which may contain mineral oil and/or fossil-derived ingredients and leave behind an unpleasant oily and greasy skin feel after use. The composition excludes mineral and organic UV filters. The creamy emulsion demonstrates breaking upon rubbing application of the composition on a substrate. The composition demonstrates stability at temperatures in a range from about 5 °C to about 45 °C for a period of eight weeks and under freeze-thaw conditions that range from about -20 °C to about 25 °C, where the stability is evidenced by lack of separation of the water and oil phases in the absence of rubbing on a substrate. The composition according to the disclosure is a water-in-oil emulsion that has a creamy texture.

[0035] The inventors developed the inventive composition to address certain deficiencies in the art, including consumer need for compositions that are formulated with sustainable, natural and/or green materials, and in particular that lack or minimize use of non-renewable ingredients (e.g., mineral oil and petrol based ingredients) and ingredients that have negative environmental impact (e.g., EDTA that mobilizes heavy metals). In some embodiments the composition is free or essentially free from non-renewable ingredients and ingredients that have negative environmental impact, and in some particular embodiments excludes or is essentially free from ingredients selected from the group consisting of parabens, phthalates, cyclomethicones, fragrance, silicone, mineral oil, synthetic dyes, gelling agents, sulfates, polyquaternium, microplastics, EDTA, silicone oils, mineral UV filter agents, organic UV filter agents, and combinations thereof. In some embodiments, the composition may include only nominal amounts of petrol based ingredients or may be free from petrol based ingredients.

[0036] The inventors also sought to address the deficiencies in the art related to instability of inverse emulsions, particularly those having a large water phase, which are vulnerable to phase separation during typical storage periods or when exposed to freeze thaw cycles. In some embodiments, the inventive composition includes a polyglyceryl ester emulsifier.

[0037] It is known to the inventors that Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate, which is typically used for lightweight, low viscosity cosmetic formulations (not thick, creamy emulsions), is employed and recommended for use in amounts that are greater than 2%.

[0038] The inventors have shown in compositions that use of polyglyceryl ester emulsifiers, for example, using Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate, at a much lower than recommended or typically used amount of less than 2%, that these compositions stably retain essentially all of the large internal phase without separation or pooling but the stability declines over time. The inventors have unexpectedly provided a composition in which inclusion of glutamic acid or a derivative thereof results in sustained stability, as shown in the examples. In addition, the inventors have unexpectedly provided a composition in which inclusion and modulation of the amount of a glycol, in some embodiments a diol, and as exemplified using propanediol allows the point at which the watery transition to be adjusted at a given strain. As shown in the examples, increasing the weight percent amount of propanediol in the composition results in an earlier, more abrupt break during application (at a particular strain) as compared with application of the same composition with lesser amount of the glycol.

[0039] Thus, the inventors have demonstrated that the inventive composition forms a robust emulsion that demonstrates freeze/thaw stability and long term (up to 8 weeks) storage stability, while retaining the property of breaking upon rubbing application to a substrate such as skin. Comparative compositions lacking the ingredients of the inventive composition disclosed herein do not meet the tests of material stability, including freeze/thaw and storage stability, as well as water breaking when rubbed on a substrate.

[0093] The examples below according to the invention are given by way of illustration and without a limiting nature. The names are the chemical name or the INCI name. The amounts are given therein as % by weight, unless otherwise mentioned. [0094] EXAMPLES

[0095] EXAMPLE 1: Compositions:

[0096] Various representative embodiments of inventive and comparative compositions are exemplified herein.

[0097] TABLE 1: Inventive Compositions 1-2 and Comparative Compositions 1-3

* Glutamic acid derivative is 47.5% active

[0098] Comparative compositions 1-4 were employed together with the Inventives in studies as shown in the examples, below, wherein Comp 1 has a different general formulation and lacks the polyglyceryl ester emulsifier and includes a different emulsifier, lacks propanediol and lacks glutamate or derivative. Comp 2 and 3 have a similar base to Inventive Compositions 1 and 2 but lack the glutamate or derivative.

[0099] In preparing the inventive composition examples, water phase (A) ingredients are mixed separately from oil phase (B) ingredients which are blended under heating then added in batch to the water phase and blended followed by measurement of viscosity.

[00100] In a representative embodiment according to the disclosure the composition includes polyglyceryl-4 diisostearate/polyhydroxystearate/sebacate present at about 1.35%; tetrasodium glutamate diacetate present at about 0.8%; propanediol present at about 1.6% or about 5%; Butyrospermum Parkii (Shea) Butter present at about 3%, Copernicia Cerifera (Carnauba) Wax present at about 0.1%, Persea Gratissima (avocado) oil present at about 3.5%, squalane present at about 6.5%, more generally, each present from about 0.1% to about 23%; water present at about 70% to about 76%, and glycerin present at about 5%, all amounts by weight of the composition. The composition also includes sodium dehydroacetate, salicylic acid, chromium oxide greens, sodium PCA, copper gluconate, sodium chloride, tocopherol, caffeine, beta-carotene, and citric acid. The composition is a creamy water-in oil emulsion comprising (a) a water phase that comprises the water, or water and a water- based hydrating agent or solvent or combination thereof, and the at least one cosmetically acceptable glycol or diol, and (b) an oil phase comprising the at least one polyglyceryl ester, in some embodiments the glutamic acid, or a derivative thereof, and the at least one oil. The composition has a ratio of the total weight of the water phase to the total weight of the at least one polyglyceryl ester in a range from about 45 to about 70. In some embodiments, the glutamic acid or derivative thereof may be in the oil phase or the water phase. In those embodiments wherein the glutamic acid includes tetrasodium glutamate diacetate, the tetrasodium glutamate diacetate is in the water phase.

[00101] EXAMPLE 2: Freeze-Thaw Stability

[00102] Referring to TABLE 1, the shown Inventive and Comparative compositions were exposed to 10 freeze-thaw cycles of -20 °C /+25 °C.

[00103] Only the Inventive compositions were stable under these conditions.

[00104] Comparative compositions 2 and 3, both lacking the glutamate or derivative, showed minor separation. Comparative composition 1 lacking the polyglyceryl ester emulsifier, propanediol and glutamate or derivative, showed separation.

[00105] EXAMPLE 3: Heat Stability

[00106] Referring again to TABLE 1, the shown Inventive and Comparative compositions were exposed to 2 months at 25 °C and 45 °C.

[00107] Comparative composition 1 lacking the polyglyceryl ester emulsifier, propanediol and glutamate or derivative showed separation under 45 °C conditions. This formula also showed separation at longer term evaluation at room temperature (approximately 6 months).

[00108] Comparative composition 2, lacking the glutamate or derivative, did not show separation under 45 °C conditions; however, it was not stable due to the softening of texture to a lotion instead of a substantially thick cream.

[00109] EXAMPLE 4: Quantifying the Transitioning Texture [00110] Rheology studies were conducted to quantify the unique transitioning texture of inventive compositions. Tested compositions were evaluated at their initial time point as well as after 2 months for stability at 25 °C and 45 °C for breaking and rheological properties. Comparative composition 1 lacking the polyglyceryl ester emulsifier, propanediol and glutamate or derivative showed softening over time and an earlier break, leading to its eventual instability of separation as shown in Examples 2 and 3. The Inventive compositions demonstrated stability over time and maintained their initial break point and rheological properties over time. Inventive Composition 1, with the lesser amount of the cosmetically acceptable glycol or diol, demonstrated breaking at a higher strain (i.e., requiring longer duration of rubbing prior to break) than Inventive Composition 2 with a greater amount of the glycol. This study demonstrated that in a composition according to the disclosure, propanediol may be used to adjust the break point of a composition. Thus, an inventive composition may be designed to require more or less rubbing of the composition on application before the emulsion will thin and release the water phase, wherein a greater amount of propanediol allows for an earlier transition by requiring less strain for the transformation as compared with the same composition having a lesser amount of propanediol applied with the same force or strain.

[00111] While the disclosure has been described with reference to described embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the disclosure. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the disclosure without departing from the essential scope thereof. Therefore, it is intended that the disclosure is not limited to the particular embodiment disclosed as the best mode contemplated for carrying out this disclosure, but that the disclosure will include all embodiments falling within the scope of the appended claims.

[00112] The articles "a" and "an," as used herein, mean one or more when applied to any feature in embodiments of the present disclosure described in the specification and claims. The use of "a" and "an" does not limit the meaning to a single feature unless such a limit is specifically stated. The article "the" preceding singular or plural nouns or noun phrases denotes a particular specified feature or particular specified features and may have a singular or plural connotation depending upon the context in which it is used. The adjective "any" means one, some, or all indiscriminately of whatever quantity.

[00113] "At least one," as used herein, means one or more than one, including two or more than two, and thus includes individual components as well as mixtures/combinations.

[00114] The transitional terms "comprising", "consisting essentially of" and "consisting of", when used in the appended claims, in original and amended form, define the claim scope with respect to what unrecited additional claim elements or steps, if any, are excluded from the scope of the claim(s). The term "comprising" is intended to be inclusive or open-ended and does not exclude any additional, unrecited element, method, step or material. The term "consisting of" excludes any element, step or material other than those specified in the claim and, in the latter instance, impurities ordinarily associated with the specified material(s). The term "consisting essentially of" limits the scope of a claim to the specified elements, steps or material(s) and those that do not materially affect the basic and novel characteristic(s) of the claimed disclosure. All materials and methods described herein that embody the present disclosure can, in alternate embodiments, be more specifically defined by any of the transitional terms "comprising," "consisting essentially of," and "consisting of."

[00115] The terms "free" and "devoid" indicates that no reliably measurable excluded material is present in the composition, typically 0% by weight, based on the total weight of the composition. The term "essentially free" means that, while it prefers that no excluded material is present in the composition, it is possible to have very small amounts of the excluded material in the composition of the invention, provided that these amounts do not materially affect the advantageous properties of the composition. In particular, "essentially free" means that excluded material can be present in the composition at an amount of less than about 0.1% by weight, based on the total weight of the composition. [00116] The term "about," means within 10% of the indicated number (e.g., "about 10%" means 9% - 11% and "about 2%" means 1.8% - 2.2%).

[00117] All percentages and ratios are calculated by weight unless otherwise indicated. All percentages are calculated based on the total composition unless otherwise indicated. Generally, unless otherwise expressly stated herein, "weight" or "amount" as used herein with respect to the percent amount of an ingredient refers to the amount of the raw material comprising the ingredient, wherein the raw material may be described herein to comprise less than and up to 100% activity of the ingredient. Therefore, weight percent of an active in a composition is represented as the amount of raw material containing the active that is used and may or may not reflect the final percentage of the active, wherein the final percentage of the active is dependent on the weight percent of active in the raw material.

[00118] The terms "weight percent" and "wt%" may be used interchangeably and mean percent by weight, based on the total weight of a composition, article or material, except as may be specified with respect to, for example, a phase, or a system that is a component of a composition, article or material. All ranges and amounts given herein are intended to include subranges and amounts using any disclosed point as an end point. Thus, a range of "1% to 10%, such as 2% to 8%, such as 3% to 5%," is intended to encompass ranges of "1% to 8%," "1% to 5%," "2% to 10%, " and so on. A range given of "about 1% to 10%" is intended to have the term "about" modifying both the 1% and the 10% endpoints. Further, a range is intended to be inclusive of the endpoints of and all numbers in the range except as expressly stated otherwise. Further still, it is understood that when an amount of a component is given, it is intended to signify the amount of the active material unless otherwise specifically stated.

[00119] Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The example that follows serves to illustrate embodiments of the present disclosure without, however, being limiting in nature. [00120] All publications and patent applications cited in this specification are herein incorporated by reference, and for any and all purposes, as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference. In the event of an inconsistency between the present disclosure and any publications or patent application incorporated herein by reference, the present disclosure controls.
