Patent Application

The invention relates to shaving compositions that are non-fatty acid-soap based, but still provide the desired lubrication for shaving. In embodiments, the shaving compositions include mixtures of amphoteric and anionic surfactants, along with other components such as, e.g., humectant, moisturizing agent, chelating agent, preservative, natural extract, opacifier, foaming agent, fragrance, and water.
Shaving foams are generally in the form of an oil-in-water emulsion, wherein the water phase contains a soap, e.g., a fatty acid-based soap. Such shaving foams can cause dryness and irritation and/or increase the roughness of the skin, especially sensitive or broken skin, due to the presence of soap in the formula. Soap-containing shaving foams can also cause premature dulling of razor blades. However, soap-free formulations include drawbacks such as difficulty in producing foams with consistent texture and with satisfactory rigidity.
The present disclosure relates to shaving compositions.
In some embodiments, the disclosure provides a shaving composition comprising:
In some embodiments, the shaving composition comprises about 2.5% w/w to about 40% w/w of the amphoteric surfactant. In further embodiments, the amphoteric surfactant comprises an amphoacetate, an amphodiacetate, a betaine, a sarcosinate, a hydroxysultaine, or a combination thereof.

In some embodiments, the disclosure provides a method of dispensing the shaving composition described herein, comprising:
It should be appreciated that the particular implementations shown and described herein are examples and are not intended to otherwise limit the scope of the application in any way.
The published patents, patent applications, websites, company names, and scientific literature referred to herein are hereby incorporated by reference in their entirety to the same extent as if each were specifically and individually indicated to be incorporated by reference. Any conflict between any reference cited herein and the specific teachings of this specification shall be resolved in favor of the latter. Likewise, any conflict between an art-understood definition of a word or phrase and a definition of the word or phrase as specifically taught in this specification shall be resolved in favor of the latter.
Unless otherwise defined herein, scientific and technical terms used in the present disclosure shall have the meanings that are commonly understood by one of ordinary skill in the art. Further, unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular. The articles “a” and “an” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.
The use of the term “or” in the claims is used to mean “and/or,” unless explicitly indicated to refer only to alternatives or the alternatives are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and “and/or.”
As used herein, the terms “comprising” (and any variant or form of comprising, such as “comprise” and “comprises”), “having” (and any variant or form of having, such as “have” and “has”), “including” (and any variant or form of including, such as “includes” and “include”) or “containing” (and any variant or form of containing, such as “contains” and “contain”) are inclusive or open-ended and do not exclude additional, unrecited, elements or method steps.
The use of the term “for example” and its corresponding abbreviation “e.g.” means that the specific terms recited are representative examples and embodiments of the disclosure that are not intended to be limited to the specific examples referenced or cited unless explicitly stated otherwise.
As used herein, “about” can mean plus or minus 10% of the provided value. Where ranges are provided, they are inclusive of the boundary values. “About” can additionally or alternately mean either within 10% of the stated value, or within 5% of the stated value, or in some cases within 2.5% of the stated value; or, “about” can mean rounded to the nearest significant digit.
As used herein, “between” is a range inclusive of the ends of the range. For example, a number between x and y explicitly includes the numbers x and y, and any numbers that fall within x and y.
Unless otherwise indicated, all weight percentages (% w/w) herein refer to the weight of the specified component relative to total weight of the composition, where the total amount of all components in the composition equals 100% by weight (100 weight %). Unless otherwise indicated, the specified amount for a component refers to the combined percentage of all substances that fall within the definition of such component. For example, “about 50% of an amphoteric surfactant” means that the combined percentage of all substances in the composition that are “amphoteric surfactants” as defined herein, is about 50%.
As described herein, the soap-free shaving compositions can produce foams of satisfactory rigidity and consistency and leave the skin lubricious enough during application and after shaving such that shaving razors and devices do not require self-lubricating mechanisms attached to the device during the shaving process. Such soap-free shaving products provide the benefits of substantially less drying and irritation of the skin as compared to soap-containing shaving products. Soap-free shaving products can also slow the dulling of razor blades compared to soap-containing shaving products, which leads to lower costs to the consumer and reduced waste.
As used herein, “soap-free” is understood as meaning containing less than 5% w/w of a fatty acid, more suitably less than 3% of a fatty acid, less than 2% of a fatty acid, and in suitable embodiments, less than 1% w/w of a fatty acid in the composition. In further embodiments, the shaving composition described herein comprises less than 0.5% w/w of a fatty acid, preferably less than 0.1% w/w of a fatty acid. Fatty acids are compounds that consist of a carboxylic acid (—COOH) and an aliphatic chain of at least six carbons, for example, medium-chain fatty acids (MCFA) containing about 6 to about 12 carbons, or long-chain fatty acids (LCFA) containing about 13 to about 21 carbons, or very long chain fatty acids (VLCFA) containing more than 22 carbons. The fatty acid may be saturated (i.e., does not contain any carbon-carbon double bonds) or unsaturated (i.e., containing at least one carbon-carbon double bond). Exemplary fatty acids that are excluded from the present shaving compositions include, but are not limited to, myristic acid, palmitic acid, stearic acid, caprylic acid, capric acid, lauric acid, arachidic acid, behenic acid, lignoceric acid, and cerotic acid.
Fatty acids described herein are distinguished from fatty acid derivatives, which can contain a modification of the carboxylic acid on a fatty acid and/or an additional functional group besides a carboxylic acid. Examples of fatty acid derivatives include, but are not limited to, sarcosinates, triglycerides, phospholipids, sphingolipids, glycolipids, fatty amides, fatty esters, fatty acid chlorides, ether carboxylates, and the like. Unless otherwise indicated, the shaving compositions described herein (i.e., that do not comprise a fatty acid) may contain a fatty acid derivative.
In some embodiments, the disclosure provides a shaving composition comprising:
