Description

Title of the invention: COSMETIC COMPOSITIONS containing lauryl laurate and semi-crystalline polymers SCOPE OF DISCLOSURE

[0001] This disclosure relates to cosmetic compositions which include lauryl laurate and a semi-crystalline polymer containing at least one alkyl acrylate chain and processes for treating skin with the cosmetic composition. CONTEXT

[0002] Many compositions, particularly cosmetic compositions, have been developed for easy and comfortable application to a targeted substrate. Unfortunately, many of these compositions are actually difficult to apply and do not provide a smooth feel upon application. Furthermore, the compositions often tend to produce a sticky sensation, resulting in poor application and spreading characteristics. This sticky, tacky feeling is undesirable for consumers. Several approaches, such as the use of mild emollients, powders, or combinations thereof, can reduce stickiness; however, the resulting cosmetic compositions may not offer sufficient appeal to the consumer and may still exhibit residual stickiness that can be felt on the skin after application.Therefore, it is desirable to offer a composition that is non-sticky, spreads easily, and is pleasant for consumers.

[0003] A cosmetic composition and processes for the use and production of cosmetic compositions which do not suffer from one or more of the above disadvantages would be desirable in art.

[0004] There is a need for compositions that are not sticky, not too thick, not too rich, not too difficult to spread, and not too greasy. The inventors of this disclosure have discovered unique cosmetic compositions and a method for using the compositions that meet these and other needs. SUMMARY

[0005] This disclosure relates to cosmetic compositions containing lauryl laurate and semi-crystalline polymers containing at least one alkyl acrylate chain. The compositions are stable, have pleasant tactile properties, are aesthetically pleasing, and easy to use. This unique combination allows for a reduction in the sticky feeling in an emulsion-based skincare formula without adding any negative sensory attributes.

[0006] One way to mitigate tackiness is to add insoluble powders or fillers (e.g., silica, cellulose), but this increases the risk of spreading difficulties and buildup during application. Furthermore, heavier oils and higher oil levels can also help to mask tackiness, at the cost of a formula that is too greasy and has an overly glossy appearance. While some waxy ingredients (e.g., alcohols / fatty acids, highly meltable natural waxes) can mask tackiness, they can also leave too much waxy residue that is difficult to spread.

[0007] The inventors have discovered that the combination of lauryl laurate and semi-crystalline polymers containing at least one alkyl acrylate chain eliminates or considerably reduces the stickiness caused by humectants, polymers, certain active ingredients, polyols and the like.

[0008] The cosmetic composition includes: a. lauryl laurate; and b. at least one semi-crystalline polymer containing at least one alkyl acrylate chain.

[0009] In some cases, the composition is in the form of an oil-in-water emulsion or a water-in-oil emulsion.

[0010] In one or more embodiments, lauryl laurate is present from about 0.1 to about 5% by weight, relative to the total weight of the composition.

[0011] In some embodiments, the compositions may include at least one semi-crystalline polymer containing at least one alkyl acrylate chain selected from homopolymers obtained by polymerization of a monomer selected from alkyl acrylates and alkyl methacrylates and from copolymers obtained by copolymerization of a monomer selected from alkyl acrylates and alkyl methacrylates with a hydrophilic monomer, preferably a hydroxyethyl (meth)acrylate, and mixtures thereof. In one or more embodiments, the semi-crystalline polymer(s) containing at least one alkyl acrylate chain is / are selected from polystearyl acrylate, polybehenyl acrylate, behenyl acrylate / 2-hydroxyethyl acrylate copolymer, stearyl acrylate / 2-hydroxyethyl acrylate copolymer, and one of their mixtures.In some embodiments, the semi-crystalline polymer(s) containing at least one alkyl acrylate chain is / are selected from the group consisting of C10-30 alkyl polyacrylate, C12-22 alkyl acrylate / hydroxyethyl acrylate copolymer, and mixtures thereof. In one or more embodiments, the content of the semi-crystalline polymer(s) containing at least one alkyl acrylate chain is present from approximately 0.1 to approximately 3% by weight relative to the total weight of the composition.

[0012] In one or more embodiments, the compositions may further comprise one or more polymer thickeners. In various embodiments, the one or more polymer thickeners are present from approximately 0.05 to approximately 5% by weight relative to the total weight of the composition.

[0013] In one or more embodiments, the compositions may further comprise one or more fatty compounds. In some embodiments, the one or more fatty compounds are present from approximately 0.1 to approximately 30% by weight, relative to the total weight of the composition.

[0014] In various embodiments, the compositions may further comprise one or more surfactants. In some embodiments, the one or more surfactants are present from approximately 0.05 to approximately 15% by weight relative to the total weight of the composition.

[0015] In one or more embodiments, the compositions may further comprise one or more cutaneous active agents. In some embodiments, the total quantity of cutaneous active agents is at least approximately 1% by weight relative to the total weight of the composition.

[0016] In one or more embodiments, the compositions may further comprise one or more water-soluble solvents. In some embodiments, the one or more water-soluble solvents are selected from the group consisting of glycerin, C2-C5 monoalcohols, polyols (polyhydric alcohols), glycols, and mixtures thereof. In one or more embodiments, the one or more water-soluble solvents are present from approximately 0.1 to approximately 30% by weight relative to the total weight of the composition.

[0017] Another aspect of this disclosure may include a cosmetic composition comprising: i. of about 0.1 to about 5% by weight of lauryl laurate; ii. of about 0.1 to about 3% by weight of C10-30 alkyl polyacrylate; iii. of about 0.05 to about 5% by weight of one or more polymer thickeners; iv. from about 0.05 to about 15% by weight of one or more surfactants; v. of approximately 0.05 to approximately 15% by weight of one or more fatty compounds; vi. of about 0.1 to about 20% by weight of one or more cutaneous active agents; vii. of about 0.1 to about 30% by weight of one or more water-soluble solvents selected from glycerin, C2-C5 monoalcohols, polyols (polyhydric alcohols), glycols and mixtures thereof; wherein all percentages by weight are based on a total weight of the composition.

[0018] Another aspect of this disclosure relates to a skin treatment method. The methods include applying the cosmetic composition according to this disclosure to the skin, in particular facial skin.

[0019] It must be understood that both the preceding general description and the detailed description that follows are provided by way of example and explanation only, and do not limit the invention. DETAILED DESCRIPTION

The composition may be in the form of an oil-in-water emulsion or a water-in-oil emulsion. The compositions typically include: a. lauryl laurate; b. at least one semi-crystalline polymer containing at least one alkyl acrylate chain. lauryl laurate

[0021] In some embodiments, the composition may include lauryl laurate.For example, compositions may include an amount of lauryl laurate ranging from approximately 0.1% by weight to approximately 5% by weight, from approximately 0.15% by weight to approximately 4.9% by weight, from approximately 0.2% by weight to approximately 4.8% by weight, from approximately 0.25% by weight to approximately 4.7% by weight, from approximately 0.3% by weight to approximately 4.6% by weight, from approximately 0.35% by weight to approximately 4.5% by weight, from approximately 0.4% by weight to approximately 4.4% by weight, from approximately 0.45% by weight to approximately 4.3% by weight, from approximately 0.5% by weight to approximately 4.2% by weight, from approximately 0.55% by weight to approximately 4.1% by weight, from approximately 0.6% by weight to approximately 4.0% by weight, from approximately 0.7% by weight to about 3.8% by weight, from about 0.8% by weight to about 3.6% by weight, from about 1% by weight to about 3.5% by weight, from about 1.5% by weight to about 3% by weight, including intermediate ranges and sub-ranges, relative to the total weight of the composition.

[0022] Semi-crystalline polymer containing at least one alkyl acrylate chain

[0023] In various embodiments, the compositions may include at least one semi-crystalline polymer containing at least one alkyl acrylate chain.

[0024] As indicated above, the composition according to the invention comprises at least one semi-crystalline polymer containing at least one alkyl acrylate chain, the alkyl radicals preferably being in C16-C22.

[0025] For the purposes of this disclosure, the term "semi-crystalline polymers" is understood to mean polymers comprising a crystallizable portion, a chain or pendant sequence in the backbone, and an amorphous portion in the skeleton, and exhibiting a first-order reversible phase change temperature, in particular a melting point (solid-liquid transition).

[0026] When the crystallizable portion is a sequence of the polymer skeleton, this crystallizable sequence has a different chemical nature from that of the amorphous sequences; the semi-crystalline polymer is, in this case, a sequenced polymer, such as diblock, triblock or multiblock, comprising at least one crystallizable sequence and at least one amorphous sequence.

[0027] By "sequence", we generally mean at least 5 identical repeating motifs. The crystallizable sequence(s) is / are then of a different chemical nature from the 5 amorphous sequences.

[0028] Advantageously, the semi-crystalline polymer containing at least one alkyl acrylate chain of the composition of the present disclosure has an average molecular weight (Mn) equal to or greater than about 2000 g / mol, preferably about 2000 to 800,000 g / mol, preferably about 3000 to 500,000 g / mol, preferably about 4000 to 150,000 g / mol, and preferably about 4000 to 99,000 g / mol.

[0029] Apart from crystallizable chains or sequences, polymer sequences are amorphous.

[0030] For the purposes of this disclosure, the term "crystallizable chain or sequence" means a chain or sequence that, if alone, would reversibly transition from an amorphous to a crystalline state, depending on whether the temperature is above or below its melting point. For the purposes of this disclosure, a chain is a group of atoms that is pendant or lateral to the polymer backbone. A sequence is a group of atoms that belong to the backbone, this group constituting one of the repeating motifs of the polymer. Advantageously, the "pendant crystallizable chain" may be a chain containing at least 6 carbon atoms.

[0031] Preferably, the polymer skeleton of semi-crystalline polymers is soluble in the oily phase.

[0032] Thus, the semi-crystalline polymer containing at least one alkyl acrylate chain which is used in the composition of the present disclosure is generally introduced into the oily phase of the composition.

[0033] Preferably, the crystallizable sequences or chains of the semi-crystalline polymers containing at least one alkyl acrylate chain represent at least about 30% by weight and, preferably, at least about 40% by weight relative to the total weight of each polymer.

[0034] Semi-crystalline polymers comprising crystallizable sequences used according to this disclosure are sequenced or multiblock polymers. They can can be obtained by polymerization of monomers bearing reactive (or ethylenic) double bonds or by polycondensation. When the polymers of this disclosure are polymers bearing crystallizable side chains, these polymers are advantageously in random or statistical form.

[0035] The semi-crystalline polymers of the present disclosure may be of synthetic origin. Furthermore, they do not comprise a polysaccharide backbone.

[0036] The semi-crystalline polymers of the composition of this disclosure may or may not be partially crosslinked. This may be a case of chemical crosslinking, by reaction with a multifunctional monomer during polymerization. It may also be a case of physical crosslinking, which may then be due either to the formation of hydrogen or dipolar bonds between groups carried by the polymer, such as dipolar interactions between carboxylate ionomers, these interactions being present in small quantities and carried by the polymer backbone; or due to phase separation between the crystallizable sequences and the amorphous sequences carried by the polymer.

[0037] Preferably, semi-crystalline polymers containing at least one alkyl acrylate chain of the composition according to this disclosure are non-crosslinked.

[0038] Examples of semi-crystalline polymers according to this disclosure containing at least one alkyl acrylate chain include those resulting from the polymerization of one or more saturated alkyl (meth)acrylates.

[0215] Water-soluble solvents and water were stirred in a suitably sized container and heated to 75 °C. Fatty compounds, surfactants, emollients, and any oil-soluble active ingredients were combined and heated in a secondary container to 75 °C until all components melted completely. The oil phase was then added to the aqueous phase at 75 °C with stirring and homogenization for 15 minutes. After this time, the container was cooled to room temperature with continuous stirring and homogenization. Below 40 °C, thickeners and polymer fillers were added. Stirring and homogenization continued until the polymers were well dispersed. The pH was then adjusted, and the remaining raw materials were added. Once homogeneous, the mixture was complete and removed from the tank at 20 °C.

[0219] (Adherence) Protocol for the sensory study

[0220] 50 pL of a blinded test sample were deposited on the back of the hand of the test subject. Using two fingers in a controlled movement, the sample was spread in a circular motion, with the test subject performing the circular motion 20 times. The sensory quality of the test sample was assessed on the back of the hand 1) during application, 2) immediately after application, and 3) two minutes after application. Subjects were asked to rate three overall attributes on a scale of 1 to 5.

[0221] The compositions shown in Example 1 were tested. The test criteria and evaluations are reported in Table 2 below. The basic formula was a cream-gel formulated and known to exhibit adhesion (Table 1, basic formula). The adhesion was primarily due to the 8% glycerin and 5% niacinamide.

[0222] The results are presented in the table below.

[0224] Sensory results demonstrated that the combination of lauryl laurate and C10-30 alkyl polyacrylate in a gel-cream base exhibited the lowest amount of stickiness with the best sensory attributes. When the formula contained only C10-30 alkyl polyacrylate (i.e., Ex. comp. 1), the formula had an overall waxy, cutaneous feel and was slightly sticky. When the formula contained only lauryl laurate (i.e., Ex. comp. 2), the formula had an overall dry finish and was sticky and tacky. When the formula contained C10-30 alkyl polyacrylate combined with an emollient comparable to lauryl laurate (i.e. Ex. comp. 3; shea butter melts above room temperature, but close to skin temperature (maximum melting at 26°C, end of melting at 34°C).If melting temperatures dictated / predicted sensory characteristics, then formulas comparing shea butter and lauryl laurate would be very similar. but this is not the case), the formula had an overall final feel of greasy texture and was a little sticky.

[0225] The preceding description illustrates and describes this disclosure. The disclosure presents and describes only the preferred embodiments, but it should be understood that the invention can be used in various other combinations, modifications, and environments, and that it may undergo changes or modifications in the scope of the inventive concepts as expressed herein, in accordance with the teachings above and / or the skills or knowledge of the relevant art. The embodiments described herein are further intended to explain the best known means to the applicant and to enable others skilled in the art to use the disclosure in such or other embodiments, and with the various modifications required by particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein. DEFINITIONS

[0226] As used herein, the terms "comprising," "having," and "including" (or "comprise," "having," and "include") are used in their broad, non-limiting sense. The expression "consisting essentially of" restricts the scope of a claim to the specified materials or steps and to those that do not materially affect the basic and innovative features of the claimed invention.

[0227] Thus, the phrase "one of their mixtures" (or "one of their combinations") is interchangeable with the phrase "their mixtures" (or "their combinations"). Throughout the disclosure, if the phrase "one of their mixtures" is used, following a list of items as shown in the following example where the letters A through F represent the items: "one or more items selected from A, B, C, D, E, F, or mixtures thereof." The phrase "one of their mixtures" does not require that the mixture include all of the items A, B, C, D, E, and F (although all of the items A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements chosen from A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E and F".

[0228] Similarly, the expression "one of its (their) salts" also refers to "its (their) salts." Thus, when the disclosure refers to "an item selected from the group consisting of A, B, C, D, E, F, one of their salts, or mixtures thereof," it indicates that one or more of A, B, C, D, and F may be included, one or more of a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included, or a mixture of any two of A, B, C, D, E, F, a salt of A, a salt of B, a salt of C, a salt of D, a salt of E, and a salt of F may be included.

[0229] The salts referred to throughout the disclosure may include salts having a counterion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is not exhaustive. The appropriate counterions for the components described herein are known in art.

[0230] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.

[0231] The term “plurality” means “more than one” or “two or more”.

[0232] An "alkyl radical" is a linear or branched saturated hydrocarbon-based group, particularly in C1-C8, more particularly in C1-C6, preferably in C1-C4 such as methyl, ethyl, isopropyl and tert-butyl.

[0233] An "alkoxy radical" is an alkyl-oxy in which the alkyl is as described above.

[0234] An "alkenyl radical" is a linear or branched hydrocarbon-based group unsaturated, especially in C2-C8, more particularly in C2-C6, preferably in C2-C4 such as ethylenyl, propylenyl.

[0235] An alkylene radical* is a linear or branched divalent hydrocarbon-based group, in particular C1-C6, preferably C1-C4, such as methylene, ethylene or propylene.

[0236] Some of the various component categories identified for cosmetic compositions may overlap. In cases where an overlap may exist and the composition / product includes two (or more than two) overlapping components, an overlapping component does not represent more than one component. For example, tocopherol may be considered both a "vitamin" and a "preservative." If a particular composition / product includes both a vitamin and a preservative, the tocopherol may serve only as a vitamin or only as a preservative (tocopherol does not serve simultaneously as a vitamin and a preservative, even though it functionally provides more than one effect).

[0237] All percentages, parts and ratios herein are based on the total weight of the compositions of the present invention, unless otherwise stated.

[0238] All ranges and values ​​disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value for deducing a subrange, and so on. Furthermore, all ranges provided are intended to include each specific range within the given ranges, as well as a combination of intermediate subranges. Thus, a range of 1 to 5 specifically includes the points 1, 2, 3, 4, and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc.; and the points 1, 2, 3, 4, and 5 include ranges and subranges of 1-5, 2-5, 3-5, 2-3, 2-4, 1-4, etc.

[0239] Apart from the examples of operation, or unless otherwise stated, all numbers expressing quantities of ingredients and / or reaction conditions may be modified by the term "approximately", whether expressly stated or not.

[0240] Furthermore, all numbers are intended to represent exact values ​​as additional embodiments, whether or not modified by the term "approximately". For example, "a quantity of approximately 1%" can be modified to mean exactly 1%. As an example, "a quantity of 1%" can be modified to mean "approximately 1%". Unless otherwise specified, the term "approximately" is understood to encompass a range of + / - 5% with respect to the stated number. However, in some embodiments, the term can be defined to encompass narrower ranges, for example, + / - 1%, 2%, 3%, or 4% with respect to the stated number.

[0241] Various components may be included in the form of salts, even if they are not explicitly stated. In other words, whenever a compound has the capacity to exist in the form of a salt, it is intended that salts will also be encompassed to the extent that such salts exist, even if the specification cannot specifically refer to a salt (or cannot refer to a salt in all instances throughout the disclosure), for example, by using a formulation such as "one of its (their) salts" or "its (their) salts." Sodium and potassium are common cations that form salts. However, additional cations such as ammonium ions, or alkanoammonium ions such as monoethanolammonium or triethanolammonium ions, can also form salts.

[0242] The expression "substantially free" or "essentially free" as used herein means that the specific material may be present in small quantities that do not materially affect the basic and innovative features of the claimed invention. For example, less than 2% by weight of a specific material may be added to a composition, relative to the total weight of the composition (provided that an amount less than 2% by weight does not materially affect the basic and innovative features of the claimed invention). Similarly, a composition "substantially free" or "essentially free" of a stated material may include less than 1.5% by weight, less than 1% by weight, less than 0.5% by weight, less than 0.1% by weight, less than 0.05% by weight, or less than 0.01% by weight, or no amount of the specified material.The expression "substantially free" or "essentially free" as used here can also mean that the specific material is not added to the composition, but that it may still be present in a raw material included in the composition.

[0243] Furthermore, all components positively presented in this disclosure may be negatively excluded from the claims; for example, a claimed composition may be "free," "substantially free" (or "substantially free") of one or more components that are positively presented in this disclosure. By way of example, silicones may optionally be included in cosmetic compositions, but in some cases, the compositions may be free or substantially free of silicones. Silicones are synthetic polymers consisting of repeating units of elemental siloxane, silicon, and oxygen, combined with other elements, most often carbon and hydrogen. Silicones are therefore also called polysiloxanes.In some cases, the cosmetic compositions in this case may be free or essentially free of dimethicones, amodimethicones, dimethiconols, cyclosiloxanes, siloxanes, etc.
