[0001] TITLE

[0002] COSMETIC COMPOSITIONS CONTAINING LAURYL LAURATE AND SEMICRYSTALLINE POLYMERS

[0003] RELATED APPLICATIONS

[0004] This application claims the benefit of US App. No. 18 / 746,183 filed June 18, 2024, and FR Utility App. No. 2408739 filed August 7, 2024, the contents of which are incorporated herein by reference in their entireties.

[0005] FIELD OF THE DISCLOSURE

[0006] The instant disclosure relates to cosmetic compositions that include lauryl laurate and one semicrystalline polymer containing at least one alkyl acrylate chain and to methods for treating skin with the cosmetic composition.

[0007] BACKGROUND

[0008] Many compositions, especially cosmetic compositions, have been developed for easy and comfortable application onto a targeted substrate. Unfortunately, many of these compositions are in fact difficult to apply and do not possess a smooth feel upon application. Moreover, compositions often have a tendency to feel tacky, yielding poor application and spreadability characteristics. The tacky and sticky feel is undesirable to consumers. Several approaches, such as using light emollients, powders, or combinations thereof may reduce tackiness; however, the resulting cosmetic compositions may not provide sufficient consumer appeal and may still have residual tackiness that can be felt on the skin after application. Therefore, it is desirable to provide a composition without having a tacky feel, easily spread and that is pleasing to consumers.

[0009] A cosmetic composition and methods of using and producing cosmetic compositions that do not suffer from one or more of the above drawbacks would be desirable in the art.

[0010] There is a need for compositions that are not tacky / sticky, not too thick, not too rich, not too draggy and not too greasy. The inventors of the instant disclosure discovered unique cosmetic compositions and method of using the compositions that address these and other needs.

[0011] SUMMARY

[0012] The instant disclosure relates to cosmetic compositions that contain lauryl laurate and semicrystalline polymers containing at least one alkyl acrylate chain. The compositions are stable, have pleasant tactile properties, are aesthetically appealing, and easy to use. The unique combination provides a reduction in sticky feeling in an emulsion-based skin care formula without adding negative sensory attributes.

[0013] One way to mitigate tack is to add insoluble powders or fillers (e.g., silica, cellulose), but the risk of drag and piling upon application increases. Additionally, heavier oils and higher levels of oils can also help cover tack, at the expense of a formula feeling too greasy and appearing too shiny. While certain waxy ingredients (e.g., fatty alcohols / acids, high melting natural waxes) can cover tack, they also can leave too much of a waxy, draggy residue.

[0014] The inventors discovered that by combining lauryl laurate and semicrystalline polymers containing at least one alkyl acrylate chain surprisingly eliminates or greatly reduces the tackiness caused by humectants, polymers, certain actives, polyols and the like.

[0015] The cosmetic composition include:

[0016] (a) lauryl laurate; and

[0022] 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 about 0.1 to about 30 wt.% based on a total weight of the composition.

[0023] In various embodiments, the compositions may further comprise one or more surfactants. In some embodiments, the one or more surfactants are present from about 0.05 to about 15 wt.% based on a total weight of the composition.

[0024] In one or more embodiments, the compositions may further comprise one or more skin active agents. In some embodiments, the total amount of the skin active agents is from at least about 1 wt.% based on a total weight of the composition.

[0036] DETAILED DESCRIPTION

[0037] The compositions of the instant case are particularly useful for treating skin, especially the skin of the face. The composition may be in the form of an oil-in-water emulsion or an oil-in-water emulsion. The compositions typically include:

[0038] (a) lauryl laurate;

[0039] (b) at least one semicrystalline polymer containing at least one alkyl acrylate chain.

[0040] Lauryl Laurate In some embodiments, the compositions may include lauryl laurate. For examples the compositions may include an amount of lauryl laurate ranging from about 0.1 wt.% to about 5 wt.%, about 0.15 wt.% to about 4.9 wt.%, about 0.2 wt. % to about 4.8 wt.%, about 0.25 wt.% to about 4.7 wt.%, about 0.3 wt.% to about 4.6 wt.%, about 0.35 wt.% to about 4.5 wt.%, about 0.4 wt.% to about 4.4 wt.%, about 0.45 wt.% to about 4.3 wt.%, about 0.5 wt.% to about 4.2 wt.%, about 0.55 wt.% to about 4.1 wt.%, about 0.6 wt.% to about 4.0 wt.%, about 0.7 wt. % to about 3.8 wt.%, about 0.8 wt.% to about 3.6 wt.%, about 1 wt.% to about 3.5 wt.%, about 1 .5 wt.% to about 3 wt.%. including ranges and sub-ranges therebetween, based on the total weight of the composition.

[0041] Semicrystalline polymer containing at least one alkyl acrylate chain

[0042] In various embodiments, the compositions may include at least one semicrystalline polymer containing at least one alkyl acrylate chain.

[0043] 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 C16-C22.

[0044] For the purposes of the instant disclosure, the term “semi-crystalline polymer” is understood to mean polymers comprising a crystallisable portion, pendent chain or block in the backbone, and an amorphous portion in the backbone, and having a first- order reversible change of phase temperature, in particular melting point (solid-liquid transition).

[0045] When the crystallisable portion is a block of the polymer backbone, this crystallisable block is of different chemical nature from that of the amorphous blocks; the semi-crystalline polymer is, in this case, a block polymer, for example of the diblock, triblock or multiblock type, comprising at least one crystallisable block and at least one amorphous block.

[0046] The term “block” is generally understood to mean at least 5 identical repeating units. The crystallisable block(s) is (are) then of different chemical nature from the 5 amorphous block(s). Advantageously, the semi-crystalline polymer containing at least one alkyl acrylate chain of the composition of the instant disclosure has an average molecular mass (Mn) of greater than or equal to about 2000 g / mol, preferably from about 2000 to 800 000 g / mol, preferably from about 3000 to 500 000 g / mol, preferably from about 4000 to 150 000 g / mol, and preferably from about 4000 to 99 000 g / mol.

[0047] Aside from the crystallisable chains or blocks, the blocks of the polymers are amorphous.

[0048] For the purposes of the instant disclosure, the term “crystallisable chain or block” is understood to mean a chain or block which, if it were alone, would change from the amorphous state to the crystalline state reversibly, depending on whether the temperature is above or below the melting point. For the purposes of the instant disclosure, a chain is a group of atoms, which is pendent or lateral relative to the polymer backbone. A block is a group of atoms belonging to the backbone, this group constituting one of the repeating units of the polymer. Advantageously, the “pendent crystallisable chain” may be a chain containing at least 6 carbon atoms.

[0049] Preferably, the polymer backbone of the semi-crystalline polymers is soluble in the oily phase.

[0050] Thus, the semi-crystalline polymer containing at least one alkyl acrylate chain that is used in the composition of the instant disclosure is generally introduced into the oily phase of the composition.

[0051] Preferably, the crystallisable blocks or chains of the semi-crystalline polymers containing at least one alkyl acrylate chain represent at least approximately 30% by weight and preferably at least approximately 40% by weight relative to the total weight of each polymer.

[0052] The semi-crystalline polymers comprising crystallisable blocks used according to the instant disclosure are block or multiblock polymers. They may be obtained by polymerising monomers bearing reactive (or ethylenic) double bonds or by polycondensation. When the polymers of the instant disclosure are polymers bearing crystallisable side chains, these polymers are advantageously in random or statistical form.

[0053] The semi-crystalline polymers of the instant disclosure may be of synthetic origin. Moreover, they do not comprise a polysaccharide backbone.

[0054] The semi-crystalline polymers of the composition of the instant disclosure may or may not be partially crosslinked. It may then be a case of chemical crosslinking, by reaction with a multifunctional monomer during the polymerisation. It may also be a case of physical crosslinking, which may then be due either to the establishment of bonds of hydrogen or dipolar type between groups borne by the polymer, such as dipolar interactions between carboxylate ionomers, these interactions being in small amount and borne by the polymer backbone; or due to a phase separation between the crystallisable blocks and the amorphous blocks borne by the polymer.

[0055] Preferably, the semi-crystalline polymers containing at least one alkyl acrylate chain of the composition according to the instant disclosure are non-crosslinked.

[0056] As examples of semi-crystalline polymers according to the instant disclosure containing at least one alkyl acrylate chain, mention may be made of those resulting from the polymerisation of one or more saturated alkyl (meth)acrylates.

[0057] Preferably, the semi-crystalline polymers bearing a crystallisable side chain are alkyl (meth)acrylate homopolymers, or copolymers of these monomers with a hydrophilic monomer.

[0250] (Tackiness)

[0251] Protocol for the sensory study

[0252] 50uL of a blinded test sample was deposited on the back of the test subject’s hand. Using two fingers in a controlled motion, the sample was spread in a circular manner, with the test subject completing the circular motion 20 times. The sensory of the test sample was evaluated on back of hand 1 ) during application, 2) immediately after application, and 3) two minutes after application. Test subjects were asked to score three overall attributes on a scale from 1 -5.

[0253] The compositions presented in Example 1 were tested. The criteria tested and assessments are reported in Table 2 below. The base formula was a gel cream formulated and known to exhibit tackiness (Table 1 , base formula). The tackiness mostly came from the 8% of glycerin and 5% of niacinamide.

[0254] The results are presented in the table below. Table 2: Sensory Results

[0255] The sensory results demonstrated that the combination of lauryl laurate and Poly C10-30 Alkyl Acrylate in a gel cream base exhibited the least amount of tackiness with the best sensory attributes. When the formula contained only the Poly C10-30 Alkyl Acrylate ( / .e. Comp. Ex.1 ), the formula exhibited an overall feel of waxy, filmy sensory and was somewhat tacky. When the formula contained only the lauryl laurate ( / .e. Comp. Ex.2), the formula exhibited an overall end feel of dryness and was tacky and sticky. When the formula contained the Poly C10-30 Alkyl Acrylate associated with an emollient comparable to the lauryl laurate ( / .e. Comp. Ex. 3; shea butter melts above room temperature, but close to skin temperature (peak melting at 26°C, melting endset at 34°C). If melting temperatures dictated / predicted the sensory characteristics, then the formulas comparing shea butter and lauryl laurate would be very similar, but that is not the case), the formula exhibited an overall end feel of greasiness and was somewhat tacky.

[0256] The foregoing description illustrates and describes the instant disclosure. The disclosure shows and describes only the preferred embodiments but it should be understood that the invention is capable to use in various other combinations, modifications, and environments and is capable of changes or modifications within the scope of the inventive concepts as expressed herein, commensurate with the above teachings and / or the skill or knowledge of the relevant art. The embodiments described herein above are further intended to explain best modes known by applicant and to enable others skilled in the art to utilize the disclosure in such, or other, embodiments and with the various modifications required by the particular applications or uses thereof. Accordingly, the description is not intended to limit the invention to the form disclosed herein.

[0257] DEFINITIONS

[0258] As used herein, the terms “comprising,” “having,” and “including” (or “comprise,” “have,” and “include”) are used in their open, non-limiting sense. The phrase “consisting essentially of” limits the scope of a claim to the specified materials or steps and those that do not materially affect the basic and novel characteristics of the claimed invention.

[0259] The terms “a,” “an,” and “the” are understood to encompass the plural as well as the singular. The term “a mixture thereof” ( or “combination thereof”) is interchangeable with the term “mixtures thereof” (or “combinations thereof”). Throughout the disclosure, if the term “a mixture thereof” is used, following a list of elements as shown in the following example where letters A-F represent the elements: “one or more elements selected from A, B, C, D, E, F, or mixtures thereof.” The term, “a mixture thereof” does not require that the mixture include all of A, B, C, D, E, and F (although all of A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of any two or more of A, B, C, D, E, and F can be included. In other words, it is equivalent to the phrase “one or more elements selected from A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.”

[0260] Likewise, the term “a salt thereof” also relates to “salts thereof.” Thus, where the disclosure refers to “an element selected from the group consisting of A, B, C, D, E, F, a salt thereof, or mixtures thereof,” it indicates that 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.

[0261] The salts referred to throughout the disclosure may include salts having a counter-ion such as an alkali metal, alkaline earth metal, or ammonium counterion. This list of counterions, however, is non-limiting. Appropriate counterions for the components described herein are known in the art.

[0262] The expression “one or more” means “at least one” and thus includes individual components as well as mixtures / com binations.

[0263] The term “plurality” means “more than one” or “two or more.”

[0264] An “alkyl radical” is a linear or branched saturated hydrocarbon-based group, particularly C1-C8, more particularly C1 -C6, preferably C1 -C4 such as methyl, ethyl, isopropyl and tert-butyl.

[0265] An “alkoxy radical” is a alkyl-oxy wherein alkyl is as described herein before.

[0266] An “alkenyl radical” is a linear or branched unsaturated hydrocarbon-based group, particularly C2-C8, more particularly C2-C6, preferably C2-C4 such as ethylenyl, propylenyl. An “alkylene radical” is a linear or branched divalent saturated C1-C8, in particular C1-C6, preferably C1-C4 hydrocarbon-based group such as methylene, ethylene or propylene.

[0267] Some of the various categories of components identified for the cosmetic compositions may overlap. In such cases where overlap may exist and the composition / product includes two overlapping components (or more than two overlapping components), an overlapping component does not represent more than one component. As an example, tocopherol may be considered both a “vitamin” and a “preservative.” If a particular composition / product includes both a vitamin and a preservative, tocopherol can serve as only a vitamin or only a preservative (tocopherol does not simultaneously serve as both the vitamin and the preservative, even though it functionally provides more than one effect).

[0268] All percentages, parts and ratios herein are based upon the total weight of the compositions of the present invention, unless otherwise indicated.

[0269] All ranges and values disclosed herein are inclusive and combinable. For examples, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value to derive a sub-range, etc. Furthermore, all ranges provided are meant to include every specific range within, and combination of sub-ranges between, the given ranges. Thus, a range from 1-5, includes specifically points 1 , 2, 3, 4 and 5, as well as sub-ranges such as 2-5, 3-5, 2-3, 2-4, 1 -4, etc.; and points of 1 , 2, 3, 4, and 5 includes ranges and sub-ranges of 1-5, 2-5, 3-5, 2-3, 2-4, 1 -4, etc.

[0270] Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and / or reaction conditions may be modified with the term “about,” whether or not expressly stated.

[0271] Additionally, all numbers are intended to represent exact values as additional embodiments, whether or not modified by the term “about.” For example, “an amount of about 1 %” can be modified to refer to exactly 1 %. As a further example, “an amount of 1 %” can be modified to refer to “about 1 %.” Unless otherwise indicated, the term “about” is understood to encompass a range of + / - 5% from the stated number. However, in some embodiments, the term may be defined to encompass narrower ranges, for example, + / - 1 %, 2%, 3%, or 4% from the stated number.

[0272] Various components may be included as salts even if not explicitly stated. In other words, whenever a compound has the ability to be in the form of a salt, it is intended that salts are also encompassed to the extent such salts exist, even though the specification may not specifically refer to a salt (or may not refer to a salt in every instance throughout the disclosure), for example, by using language such as “a salt thereof” or “salts thereof.” Sodium and potassium are common cations that form salts. However, additional cations such as ammonium ions, or alkanolammonium ions such as monoethanolammonium or triethanolammonium ions, may also form salts.

[0273] The term “substantially free” or “essentially free” as used herein means the specific material may be present in small amounts that do not materially affect the basic and novel characteristics of the claimed invention. For instance, there may be less than 2% by weight of a specific material added to a composition, based on the total weight of the composition (provided that an amount of less than 2% by weight does not materially affect the basic and novel characteristics of the claimed invention). Similarly, a composition “substantially free” or “essentially free” of a stated material may include less than 1 .5 wt.%, less than 1 wt.%, less than 0.5 wt.%, less than 0.1 wt.%, less than 0.05 wt.%, or less than 0.01 wt.%, or none of the specified material. The term “substantially free” or “essentially free” as used herein may also mean that the specific material is not added to the composition but may still be present in a raw material that is included in the composition.

[0274] Furthermore, all components that are positively set forth in the instant disclosure may be negatively excluded from the claims, e.g., a claimed composition may be “free,” “essentially free” (or “substantially free”) of one or more components that are positively set forth in the instant disclosure. As an example, silicones can optionally be included in the cosmetic compositions but in some instances the compositions may be free or essentially free from silicones. Silicones are synthetic polymers made up of repeating units of siloxane, elemental silicon and oxygen, combined with other elements, most often carbon and hydrogen. Thus, silicones are also called polysiloxanes. In some instances, cosmetic compositions of the instant case can be free or essentially free from dimethicones, amomdimethicones, dimethiconols, cyclosiloxanes, siloxanes, etc.
