CROSS-REFERENCE TO RELATED APPLICATION

[001] This application claims the benefit of priority from U.S. Provisional Application No. 63/285,308, entitled “Personal Care Compositions” and filed December 2, 2021, the contents of which is hereby incorporated herein in its entirety.

BACKGROUND

[002] Liquid cleansing compositions, such as aqueous foaming compositions like hand soaps, facial soaps or cleansers, body washes, and shower gels, should desirably have acceptable levels of foam production for consumer satisfaction. Foam production, for example, is a key attribute for consumers when choosing products. To achieve a desirable foam production, manufacturers incorporate sufficient quantities of foaming agents, such as surfactants, into the compositions.

[003] However, in recent years, consumer demand for more natural products has increased - e.g., interest in the origin of raw materials and products with ingredients with a high degree of naturality. It is a challenge to produce formulations that have the physical characteristics that consumers expect, including desirable amounts of foam production and sufficient viscosity, while simultaneously achieving a high degree of naturality. Moreover, liquid consumer products normally contain different species of surfactants. Consequently, manufacturers are shifting to the use of natural/sustainable surfactant substitutes. One challenge with surfactant substitutes, however, is maintaining an acceptable foaming volume that is still acceptable for consumers.

[004] Accordingly, there is an ongoing need for improved a personal care products that meet the desires of consumers.

BRIEF SUMMARY

[005] This summary is intended merely to introduce a simplified summary of some aspects of one or more implementations of the present disclosure. Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. This summary is not an extensive overview, nor is it intended to identify key or critical elements of the present teachings, nor to delineate the scope of the disclosure. Rather, its purpose is merely to present one or more concepts in simplified form as a prelude to the detailed description below. [006] The personal care compositions of the instant disclosure surprisingly achieve a high level of foaming quality, e.g., foaming volume with a reduced amount or no sulfate-based anionic surfactants (e.g., sodium lauryl sulfate). Without being bound by theory, sulfate systems are typically recognized as being easier to work with because they provide a high level of foam and can facilitate thickening with salt. It was discovered that personal care compositions comprising certain surfactant systems are able to achieve a desirably high level of level of foam production, provide a gentle cleansing (e.g., does not strip keratin substrates and/or overly dries keratin substrates, such as skin.), while utilizing a minimal amount or being free of sulfate-based surfactants. Additionally or alternatively, certain embodiments of the personal care compositions achieve the foregoing benefits while having a high level of naturality (e.g., have a high percent of ingredients that are natural and/or naturally derived). In one aspect, the personal care compositions of the disclosure can comprise a naturally derived oil while maintaining the clarity that is sometimes lost with the inclusion of oils. In another aspect, the personal care compositions of the disclosure comprises one or more actives that can provide improved hydration and soothing to the skin, e.g., wherein the skin barrier is damaged and/or irritated.

[007] In one aspect, the disclosure provides a personal care composition (e.g., a skin care composition) (e.g., a foaming facial cleanser) comprising:

• an effective amount of a polyol emollient (e.g., glycerine, 1 ,3-propanediol, isoprene glycol, pentylene glycol, hexylene glycol, glycols such as ethylene glycol, propylene glycol, butylene glycol, diethylene glycol and dipropylene glycol, polyglycerols with 2 to 6 repeating units, for instance diglycerol, erythritol, arabitol, adonitol, sorbitol, dulcitol, glucose, fructose, xylose, trehalose, sucrose, maltose, saccharose and lactose, and mixtures thereof.)

• a surfactant system, wherein the surfactant system comprises: o an effective amount of an anionic surfactant, wherein the surfactant is an anionic derivative of proteins of plant origin or of silk proteins (e.g., sodium cocoyl apple amino acid surfactant); and o an effective amount of a non-ionic surfactant, (e.g., wherein the non-ionic surfactant is selected from an alkyl glucoside, a lactylate having carbon chains between Cs and Ci6, and a blend of an alkyl glucoside and a lactylate having carbon chains between Cs and Ci6 (e.g., ammonium, sodium, potassium and alkanolamine (e.g., triethanolamine) salts of lauroyl lactylate (e.g., sodium lauroyl lactylate), cocoyl lactylate, lauroyl lactylate, and caproyl lactylate); and

• water.

[008] In another aspect, the disclosure provides a method of depositing a topically active compound on the skin, comprising applying an effective amount of any of personal care compositions as disclosed herein to the skin.

[009] Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating some typical aspects of the disclosure, are intended for purposes of illustration only and are not intended to limit the scope of the disclosure.

[0011] FIG. 1 is a graph of the average rheological foam curves for two non-limiting example compositions in accordance with aspects of the invention.

[0012] FIGS. 2A and 2B are bar graphs of the elasticity and yield stress, respectively, of the foam of two non-limiting example compositions in accordance with aspects of the invention.

[0013] FIG. 3 is a bar graph illustrating the amount of sebum removed by non-limiting example compositions or a control in accordance with aspects of the invention.

[0014] It should be understood that the various aspects are not limited to the compositions, arrangements, and instrumentality shown in the figures.

DETAILED DESCRIPTION

[0015] The following description of various typical aspect(s) is merely exemplary in nature and is in no way intended to limit the disclosure, its application, or uses.

[0016] As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. The term “about” when referring to a number means any number within a range of 10% of the number. For example, the phrase “about 2 wt.%” refers to a number between and including 1.8 wt.% and 2.2 wt.%.

[0017] As used herein, the term “effective amount” means the quantity of a surfactant required to provide adequate foam volume and structure to the personal care compositions. In one aspect, the “effective amount” of surfactant is the amount of surfactant required so that the foaming volume of the personal care composition is at parity, or improved, relative to a control composition (e.g., where the control contains a sulfate based anionic surfactant (e.g., sodium lauryl sulfate or sodium laureth sulfate)).

[0018] As used herein, “polyol” is understood to mean any organic molecule comprising at least two free hydroxyl groups.

[0019] Unless otherwise specified, all percentages and amounts expressed herein and elsewhere in the specification should be understood to refer to percentages based on the weight of the total composition. The amounts given are based on the active weight of the material.

[0020] As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural references unless the context dictates otherwise. The singular form of any class of the ingredients refers not only to one chemical species within that class, but also to a mixture of those chemical species. The terms “a” (or “an”), “one or more” and “at least one” may be used interchangeably herein. The terms “comprising”, “including”, and “having” may be used interchangeably. The term “include” should be interpreted as “include, but are not limited to”. The term “including” should be interpreted as “including, but are not limited to”.

[0021] “Volatile”, as used herein, means having a flash point of less than about 100° C. “Nonvolatile”, as used herein, means having a flash point of greater than about 100° C.

[0022] When referring to chemical structures, and names, the symbols “C”, “H”, and “O” mean carbon, hydrogen, and oxygen, respectively. The symbols “=” and “=” mean single bond, double bond, and triple bond, respectively. For readability purposes, the chemical functional groups are in their adjective form; for each of the adjectives, the word “group” is assumed. For example, the adjective “alkyl” without a noun thereafter, should be read as “an alkyl group.” [0023] Any member in a list of species that is used to exemplify or define a genus, may be mutually different from, or overlapping with, or a subset of, or equivalent to, or nearly the same as, or identical to, any other member of the list of species. Further, unless explicitly stated, such as when reciting a Markush group, the list of species that defines or exemplifies the genus is open, and it is given that other species may exist that define or exemplify the genus just as well as, or better than, any other species listed.

[0024] The phrases, “a mixture thereof,” “a combination thereof,” or “a combination of two or more thereof’ do 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 the group consisting of A, B, C, D, E, F, and a mixture of any two or more of A, B, C, D, E, and F.” 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, and a mixture 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.

[0025] All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the personal care compositions of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure. In some instances, the personal care compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound that is added into the personal care composition by itself. For example, a personal care composition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds.

[0026] The present invention provides, in an aspect, a personal care composition (Composition 1.0), (e.g., a foaming facial cleanser), comprising:

EXAMPLES

Example 1

[0097] The following are non-limiting examples of facial cleansers of the disclosure comprising the surfactant system.

Table 1 Example 2

[0098] Two non-limiting, example personal care compositions (Example Compositions C and D) was prepared in accordance with aspects of the disclosure. The formulations of Example Compositions C and D are shown in Table 2.

Table 2

Example 3

[0099] Example Compositions C and D were evaluated to assess their respective rheological foaming characteristics. Samples from Example Compositions C and D were dispensed individually in the form of foam onto the bottom plate of a AR2000 rheometer, available from TA INSTRUMENTS, to separately assess the rheological foaming characteristic of Example Compositions C and D. Parallel plate geometry was used, but with a serrated surface, which prevents slip of the bubbles on the surface of the plate. The temperature of the bottom plate was set to 25 °C. After the samples of Example Compositions C or D were pumped in the form of foam onto the bottom plate, the top plate was lowered down until the gap between the two plates became 1 mm. As the gap decreased, the foam was squeezed out.

[00100] A strain sweep test was conducted where shear strain ramped from 0.1 to 1000% step- wise with a fixed angular frequency of 10 rad/s. During the measurement, shear stress and elastic modulus were measured.

[00101] The elastic modulus was plotted against shear stress in log-log scale. When low shear stress is applied, as the structure of foam was not destroyed, elasticity of the foam can be measured. Elastic modulus is independent from the applied shear stress, which appears as the plateau of elastic modulus (G’). As shear stress increases beyond yield stress, the structure of foam breaks, which results in the decrease in elastic modulus. These two parameters are governed by foam structure. Both parameters typically increase with higher bubble fraction and smaller bubble size, e.g., when foam is denser. G’ and yield stress are obtained by drawing two tangential lines. By extrapolating the fit line from the low stress regime, G’ was obtained. Yield stress is the stress where the two lines meet.

[00102] FIG. 1 is a graph of the average rheological foam curves for Example Compositions C and D. FIG. 2A and FIG. 2B are bar graphs of the elasticity and yield stress, respectively, of the foams of Example Compositions C or D.

Example 4

[00103] Example Compositions C and D were evaluated to assess their ability to remove sebum. To evaluate the cleansing ability of Example Compositions C and D, sebum was evenly spread onto films using a spatula. The weight of the sebum after spreading was then measured to make sure that the weight on each film was approximately 0.1 grams. Samples of 0.25 grams of either Example Composition C or Example Composition D were placed on the respective films and gently spread using fingertips. The films were subsequently wet with 0.25 mL of water. After 1 hour, the films were rinsed with water for 40 seconds.

[00104] The amount of residual sebum on the films was then measured and analyzed using image J software. FIG. 3 is a bar graph illustrating the amount of sebum removed by Example Composition C, Example Composition D, and water, which was used as a control. Notably, Example Compositions C and D removed about 88% and about 87%, respectively of the sebum while water removed about 34% of the sebum.
