Definitions
- the present invention generally relates to personal care compositions and methods for manufacturing them, and more particularly relates to human sebum mimetics derived from botanical sources and methods for making them.
- Sebum Human sebum is secreted by the sebaceous glands that are found over substantially the entire skin surface (except the palms of the hands and soles of the feet), but are found predominately on the scalp, face, chest, and back. Sebum is involved in development of the epidermal structure and maintenance of the epidermal permeability barrier, carrying antioxidants to the skin surface, protecting the skin from microbial colonization, generating body odor, and producing pheromones.
- sebum When secreted, human sebum is a complex mixture of triglycerides, wax esters, sterol esters, cholesterol, cholesterol esters, and squalene. As the sebum is secreted, it consists primarily of triglycerides and wax esters, which are broken down by commensal microbes into diglycerides, monoglycerides, and the constituent free fatty acids.
- the fatty acid chain lengths of human sebum vary considerably, but have predominantly 16 and 18 carbons, such as in the case of stearic acid (18 carbons with no double bond (hereinafter denoted C18:0)), oleic acid (C18:1 with one double bond on the ninth carbon (hereinafter denoted C18:1 ⁇ 9)), linoleic acid (C18:2 ⁇ 9 ⁇ 12), palmitic acid (C16:0), and sapienic acid (16:1 ⁇ 6).
- Loss of human sebum can be due to a variety of environmental factors such as bathing, weather conditions, chemical products, and poor nutrition, and also can be due to genetics. For example, a natural lack of sebum is observed on the scalp of African-Americans. A loss of sebum can result in itching, dandruff, wrinkles, diaper rash and the like on the skin. In addition, the hair may become brittle and dry without a sufficient amount of sebum to moisturize it. While a variety of products exist that attempt to repair the suppleness caused by lack of sebum, many of these products contain synthetic components or components that are derived from animals and do not mimic the structure and formulation of human sebum. In this regard, the products are not absorbed by the skin as readily as human sebum. In addition, the products are often made from unstable ingredients that exhibit a short shelf life.
- a human sebum mimetic comprises a wax ester derived from interesterification of a refined botanical oil comprising palmitoleic and refined jojoba oil, a phytosterol, and phytosqualene.
- a method for producing a human sebum mimetic comprises mixing refined macadamia oil and refined jojoba oil, interesterifying the refined macadamia oil and the refined jojoba oil, adding a phytosterol after the interesterifying, and adding phytosqualene after the interesterifying.
- a human sebum mimetic comprises a wax ester comprising a fatty acid having 16 carbons and one double bond and that is derived from a plant source, a phytosterol, and phytosqualene.
- compositions that mimic human sebum.
- the approximate composition of human sebum includes by weight percent (wt. %) (from Pierre Agache, “Sebaceous Physiology,” Measuring The Skin, Springer-Verlog, 2004, pp. 271-280):
- the human sebum mimetics contemplated herein are plant based, that is, the components of the mimetics are derived either physically or chemically from plant sources.
- the mimetics are plant-derived analogs of human sebum in that they are derived from phytosqualene, phytosterols, a refined botanical oil such as macadamia oil, which is the source of the mimetic's triglycerides, and refined jojoba oil, which is the source of the mimetics' wax esters.
- the term “refined oil” means crude oil that has had undesirable compounds such as free fatty acids, carbohydrates, metals, proteins, and the like removed using caustic agents, washing, and centrifugation.
- the human sebum mimetic is derived from phytosqualene in an amount of about 5 to about 20 wt. % of the entire mimetic, refined jojoba oil in an amount of about 20 to about 35 wt. % of the entire mimetic, refined macadamia oil in an amount of about 45 to about 65 wt. % of the entire mimetic, and phytosterols in an amount of about 0.5 to about 10 wt. % of the entire mimetic.
- the human sebum mimetic is derived from phytosqualene in an amount of about 11 to about 15 wt. % of the entire mimetic, refined jojoba oil in an amount of about 29 to about 33 wt. % of the entire mimetic, refined macadamia oil in an amount of about 51 to about 55 wt. % of the entire mimetic, and, phytosterols in an amount of about 1 to about 5 wt. % of the entire mimetic.
- the human sebum mimetic is derived from the following composition in weight percent:
- human sebum has particularly high levels of palmitic acid (16:0), sapienic acid (16:1 ⁇ 6), and oleic acid (C18:1 ⁇ 9).
- the human sebum mimetics contemplated herein also comprise high levels of palmitic acid and oleic acid, as macadamia oil itself comprises about 8.8 wt % palmitic acid and about 58 wt. % oleic acid.
- the human sebum mimetic comprises about 1 to about 10 wt. % palmitic acid, in a preferred embodiment about 3 to about 7 wt. % palmitic acid, and in a more preferred embodiment about 4.8 wt. % palmitic acid.
- the human sebum comprises about 25 to about 35 wt. % oleic acid, in a preferred embodiment about 30 to about 34 wt. % oleic acid, and in a more preferred embodiment about 31.6 wt. % oleic acid.
- sapienic acid is unique among mammals. Palmitoleic acid (16:1 ⁇ 9), an analog of sapienic acid, is a substitute for the sapienic acid. While palmitoleic acid is fairly rare in the plant kingdom, macadamia oil has the highest palmitoleic acid content of the currently-available commercial oils, with about 16-22% palmitoleic acid. Accordingly, the inventors have found that by interesterifying the refined macadamia oil and the refined jojoba oil of the human sebum mimetic, a wax ester comprising palmitoleic acid results.
- the genera of these species include Thunbergia, Doxantha, Alophia, Roureopsis, Telopea, and Asclepias.
- the human sebum mimetic comprises palmitoleic acid in an amount of about 5 to about 15 wt. % of the entire mimetic composition. In a preferred embodiment, the human sebum mimetic comprises palmitoleic acid in an amount of about 8 to about 12 wt. % of the entire mimetic composition and, in a more preferred embodiment, the human sebum mimetic comprises palmitoleic acid in an amount of about 9.7 wt. % of the entire mimetic composition. In a most preferred embodiment, the human sebum mimetic comprises the following fatty acids and fatty alcohols in weight percent:
- Fatty acids Wt. % Fatty Alcohols Wt. % Myristic acid (14:0) 0.5 cis-11-Eicosenaol (20:1) 5.9 Palmitic acid (16:0) 4.8 cis-13-docosenol (22:1) 6.3 Palmitoleic acid (16:1) 9.7 cis-15-tetracosenol (24:1) 1.9 Stearic acid (18:0) 1.9 Unknown 18:1 (18:1) 0.1 Oleic acid (18:1) 31.6 cis-Vaccenic acid (18:1) 1.6 Linoleic acid (18:2) 1.3 Linolenic acid (18:3) 0.1 Arachidic acid (20:0) 1.5 cis-11-Eicosenoic acid (20:1) 13.9 Behenic acid (22:0) 0.5 Erucic acid (22:1) 2.9 Lignoceric acid (24:6) 0.2 Nervonic acid (24:1) 0.3.
- the human sebum mimetics contemplated herein comprise additional functional additives, that is, an ingredient added to perform a particular function.
- the human sebum mimetics may comprise tocopherols.
- the human sebum mimetic comprises about 100 to about 2000 parts per million (ppm) of 70% tocopherols, preferably about 1430 ppm.
- the human sebum mimetics may also comprise fragrances, dyes, pigments, preservatives, antioxidants, moisturizers, and the like.
- the human sebum mimetics may comprise emollients or thickeners, such as, FLORAESTERS 20 (FE-20) available from International Flora Technologies, Ltd. of Chandler, Ariz. FLORAESTERS 20 may be used to increase the viscosity and/or the bulk melting/dropping point of the mimetic, to more closely replicate the wax ester profile of human sebum, etc.
- the human sebum mimetics may be used as a component in a wide range of personal care products, such as a hair care lotions, shampoos, hair conditioners, hair gels, hair oils, hair colors, hair relaxers, hand lotions, facial lotions, eye creams, facial soaps, body lotions and creams, body scrubs, shaving gels, hair removers, sanitary wipes, and the like.
- personal care products such as a hair care lotions, shampoos, hair conditioners, hair gels, hair oils, hair colors, hair relaxers, hand lotions, facial lotions, eye creams, facial soaps, body lotions and creams, body scrubs, shaving gels, hair removers, sanitary wipes, and the like.
- the human sebum mimetics may facilitate the natural healing and recovery system of the human skin and accelerate cell turn-over and topical blood circulation, thereby decreasing the appearance of wrinkles, dark circles under eyes, and age spots.
- the human sebum mimetics may also reduce irritation on the scalp through natural healing and improve
- the human sebum mimetics contemplated herein are particularly suitable as substitutes for lost human sebum due to their stability. Oil stability is measured according to the American Oil Chemists' Society's Official Method Cd 12b-92 at 110° C. In one embodiment, the human sebum mimetics contemplated herein have an oil stability index greater than 50 hours at 110° C. In this regard, the mimetics are substantially resistant to oxidation and have a shelf life that makes them desirable as, and in, personal care products.
