[0001] This application claims priority to U.S. Patent Application No. 63 / 520,962, filed August 22, 2023, entitled “Personal Care Compositions,” the contents of which are incorporated herein by reference in their entirety for all purposes. Background Technology

[0002] Reactive oxygen species (ROS) are free radicals that can react with various cellular proteins in the skin, such as collagen, elastin, and glycosaminoglycans. ROS cause collagen and elastin to cross-link, leading to wrinkles and reducing the skin's self-repair ability. Therefore, ROS-induced skin damage can contribute to physiological aging or lead to skin conditions. Antioxidants can eliminate and reduce excess ROS production and mitigate its damage to cells in various tissues, including the skin.

[0003] Furthermore, in the skin health sector, recent consumer trends demand products that are as simple as possible, yet still provide the acceptable skin health benefits that consumers are already accustomed to from products containing multiple ingredients. However, when using fewer ingredients, there is a greater focus on maximizing the effects and efficacy of each ingredient to provide consumers with antioxidant and skin health benefits.

[0004] Therefore, there is a need for a skin health product that is simple yet can provide or exceed the skin health benefits found in products containing multiple ingredients that claim to have skin health benefits. Summary of the Invention

Although certain embodiments of the invention have been specifically described herein, those skilled in the art will readily recognize that the same principles apply equally to and can be used in other compositions and methods. Before explaining the embodiments disclosed herein in detail, it should 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 descriptive purposes and not for limiting purposes.

[0066] As used herein and in the appended claims, the singular forms “a,” “an,” and “the” include plural references unless the context otherwise requires. The singular form of any class of ingredients refers not only to one chemical substance in that class but also to mixtures of such chemical substances. The terms “a” (or “an”), “one or more,” and “at least one” are used interchangeably herein. The terms “comprising,” “including,” and “having” are used interchangeably. The term “include” should be construed as “including, but not limited to.”

[0067] As used throughout, a range is used as a shorthand to describe the individual values ​​within that range. Any value within the range can be chosen as an endpoint. Therefore, the range 1-5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. When referring to numbers, the term "about" refers to any number within a 10% range of that number. For example, the phrase "about 2 wt.%" refers to a number between 1.8 wt.% and 2.2 wt.%, inclusive.

[0068] All references cited in this document are incorporated herein by reference in their entirety. In the event of any discrepancy between the definitions in this disclosure and those in the cited references, this disclosure shall prevail.

[0069] The abbreviations and symbols used herein have their ordinary meanings unless otherwise stated. The abbreviation "wt.%" refers to a weight percentage relative to the personal care composition. The symbol "°" refers to degrees, such as temperature or angle. The symbols "hr," "min," "mL," "nm," and "μm" refer to hours, minutes, milliliters, nanometers, and micrometers, respectively. The abbreviation "UV-VIS" refers to a spectrometer or spectroscopy, meaning ultraviolet-visible light. The abbreviation "rpm" indicates revolutions per minute.

[0070] As used in this article, "volatile" means having a flash point of less than about 100°C. As used in this article, "non-volatile" 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" represent carbon, hydrogen, and oxygen, respectively. The symbols "-", "=", and "≡" represent single, double, and triple bonds, respectively.

[0072] Any member of a species list used to exemplify or define a genus may be distinct from, overlap with, be a subset of, be equivalent to, or be nearly identical to, or be the same as any other member of that genus. Furthermore, for example, when listing the Markush group, the species list defining or defining the genus is open-ended and assumes the existence of other species that define or define the genus as well as, or better than, any other species listed, unless explicitly stated otherwise.

[0073] The phrases “mixtures thereof,” “combinations thereof,” or “combinations of two or more thereof” do not require that the mixture include all of A, B, C, D, E, and F (although it may include all of A, B, C, D, E, and F). Rather, it indicates a mixture that may include any two or more of A, B, C, D, E, and F. 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 mixtures of any two or more of A, B, C, D, E, and F.” Similarly, the term “a salt thereof” also refers to “salts thereof.” Therefore, when this disclosure refers to "an element selected from the group consisting of A, B, C, D, E, F, their salts and mixtures thereof", it means that it may include one or more of A, B, C, D and F, one or more of the salts of A, B, C, D, E and F, or a mixture of any two of the salts of A, B, C, D, E, F, the salts of A, B, C, D, E and F.

[0075] Some of the components in the defined categories may overlap. In cases where overlap is possible and the personal care composition contains two components (or more than two overlapping components), the overlapping compounds do not represent more than one component. For example, some compounds may be characterized as polysaccharides and thickeners. If a particular personal care composition contains and / or lists both polysaccharides and thickeners, a compound that can be characterized as both a polysaccharide and a thickener will only act as a polysaccharide or a thickener, not both.

[0076] For readability purposes, chemical functional groups are given their adjectival forms; for each adjective, the word "group" is assumed. For example, the adjective "alkyl" without a noun should be read as "alkyl group".

[0094] Amaranth extracts can be obtained from the seeds of Amaranth plants, preferably including proteins and starches obtained from Amaranth seeds. Amaranth extracts may contain aqueous, alcoholic, or oil carriers. Starch from Amaranth seeds is likely the most abundant non-solvent component in Amaranth extracts. Without being limited to any particular theory, it is believed that the particle size and rapid degradation by amylases of starch from Amaranth seeds may contribute to the beneficial properties of personal care compositions.

[0095] Preferably, the proteins contained in the amaranth extract are primarily composed of soluble proteins, such as albumin and globulins. Without being limited by any particular theory, it is believed that the amino acid composition of amaranth seed proteins has higher levels of lysine and sulfur-containing amino acids compared to other cereal seeds, contributing to an amino acid profile in the amaranth extract that is close to and / or similar to that of animal proteins.

[0096] In some cases, amaranth extracts can be obtained by extracting seeds with a suitable solvent at a temperature between room temperature and the solvent's boiling point, optionally grinding or flattening the seeds, recovering the liquid phase, and then treating it appropriately to obtain an aqueous solution of the amaranth extract. This solution can then be stabilized and / or sterilized, or the solvent can be evaporated until a dry, solid, powdered amaranth extract is obtained. Suitable solvents are advantageously selected from water, C1-C4 aliphatic alcohols, acetone, or mixtures thereof in all proportions, particularly water / acetone or water / alcohol mixtures, in proportions of 0 to 100% acetone or alcohol. The weight ratio of amaranth seeds to solvent can advantageously be from about 1:5 to about 1:20.
