Description

PERSONAL CARE COMPOSITIONSCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of priority from U.S. Patent Application No. 63 / 520,962, filed August 22, 2023, titled Personal Care Compositions, the content of which is hereby incorporated herein in its entirety, for all purposes.BACKGROUND

[0002] Reactive oxygen species (ROS) are free radicals that can react with various cellular proteins in the skin, for example, collagen, elastin and glycosaminoglycans. ROS causes cross- linking of collagen and elastin resulting in wrinkles and decreasing the skin's ability to repair itself. Thus, the skin damage caused by ROS can contribute to the physiology of aging or lead to skin disorders. Antioxidants can scavenge and decrease the excessive ROS produced and mitigate its damage to the cells of different tissues, including skin.

[0003] Furthermore, in the field of skin health, recent consumer trends are requiring products be as simple as possible but still provide acceptable skin health benefits that consumers have grown accustomed to in products with a number of ingredients. However, when using fewer ingredients, there is more of an emphasis on maximizing the results and efficacy of each ingredient in order to deliver antioxidant and skin health benefits to a consumer.

[0004] Accordingly, there is a need for a skin health product that is simple but that can also provide, or exceed, the skin health benefits seen in products that contain numerous ingredients that claim to have skin health benefits.BRIEF SUMMARY

[0063] FIGURE is a bar graph of the tactile characteristics a non-limiting example composition in accordance with aspects of the invention.

[0064] It should be understood that the various aspects are not limited to the arrangements and instrumentality shown in the drawings.DETAILED DESCRIPTION

[0065] For illustrative purposes, the principles of the present invention are described by referencing various exemplary embodiments thereof. Although certain embodiments of the invention are specifically described herein, one of ordinary skill in the art will readily recognize that the same principles are equally applicable to, and can be employed in other compositions and methods. Before explaining the disclosed embodiments of the present invention in detail, it is to be understood that the invention is not limited in its application to the details of any particular embodiment disclosed herein. The terminology used herein is for the purpose of description and not of limitation.

[0066] 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”.

[0067] 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.%.

[0068] All references cited herein are hereby incorporated by reference in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.

[0069] The abbreviations and symbols as used herein, unless indicated otherwise, take their ordinary meaning. The abbreviation “wt.%” means percent by weight with respect to the personal care composition. The symbol “°” refers to a degree, such as a temperature degree or a degree of an angle. The symbols “hr”, “min”, “mL”, “nm”, and “pm” refer to hour, minute, milliliter,nanometer, and micrometer, respectively. The abbreviation “UV-VIS” referring to a spectrometer or spectroscopy, means Ultraviolet-Visible. The abbreviation “rpm” means revolutions per minute.

[0070] “Volatile”, as used herein, means having a flash point of less than about 100° C. “Non- volatile”, as used herein, means having a flash point of greater than about 100° C.

[0071] 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.

[0072] 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.

[0073] 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 ofA, 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.

[0074] 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 carecomposition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingrcdicnt(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds.

[0075] Some of the various categories of components identified may overlap. In such cases where overlap may exist and the personal care composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, certain compounds may be characterized as both a polysaccharide and a thickener. If a particular personal care composition includes and / or recites both a polysaccharide and a thickener, the compound that may be characterized as both a polysaccharide and a thickener will serve only as either the polysaccharide or the thickener — not both.

[0076] 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.”

[0094] The amaranth extract may be obtained from amaranth seeds and preferably includes proteins and starches obtained from amaranth seed. The amaranth extract may comprise an aqueous carrier, an alcohol carrier, or an oil carrier. The starch of the amaranth seeds may be the most abundant non-solvent component of the amaranth extract. Without being limited to any particular theory, it is believed that the particle size and quick degradation of the starches of amaranth seed by amylases may contribute to the beneficial properties of the personal care composition.

[0095] Preferably, the proteins obtained from amaranth seeds that are contained in the amaranth extract arc mainly composed of soluble proteins, such as albumins and globulincs. Without being limited to any particular theory, it is believed that the amino acid composition of the proteins of amaranth seeds, which have a high level of lysine and sulfur amino acids relative than other cereal seeds, contributes to the amino acid profile of amaranth extract approaching and / or being similar to that of animal protein.

[0096] The amaranth extract may, in some cases, be obtained by extracting the seeds, optionally ground or flattened, with an appropriate solvent, at a temperature between room temperature and the boiling point of the solvent, then by recovery of the liquid phase, which is then treated appropriately to obtain an aqueous solution of amaranth extract. This solution can then be stabilized and / or sterilized, or the solvent can be evaporated until a dry, solid, powdery amaranth extract is obtained. The appropriate solvent is advantageously chosen from water, C1-C4 aliphatic alcohols, acetone, or mixtures thereof in all proportions, in particular water / acetone or water / alcohol mixtures, in proportions varying from 0 to 100% acetone or alcohol. The weight ratio of amaranth seed to solvent can advantageously be from about 1:5 to about 1:20.
