The present disclosure relates to novel cosmetic hair compositions comprising isoeicosane and at least one nonsilicone fixing polymer. It also relates to a cosmetic process, for instance a process for fixing and/or holding a hairstyle using the compositions disclosed herein, and to the use of these compositions for producing a cosmetic formulation intended, for example, for holding and/or shaping a hairstyle.
It is known practice to use isoeicosane, a nonvolatile hydrocarbon-based oil, as a conditioning agent in cosmetic hair compositions. For example, patent application FR 2,815,853 describes cosmetic hair compositions in the form of a mousse and comprising at least one aminoplast backbone polymer, with isoeicosane as possible conditioning agent.
However, there is a need for hair products that make it possible to give the hair some hold and a long-lasting appearance of sheen, without making it too markedly greasy in nature. Such properties are not always provided by the compositions of the state of the art.
The present disclosure proposes to provide a solution to this need. For instance, the present inventors have found that compositions comprising isoeicosane and at least one nonsilicone fixing polymer can give the hair an intense and persistent sheen and can make the hair particularly smooth to the touch.
It is also disclosed herein that these compositions can be formulated in an alcoholic medium.
Other aspects of the present disclosure will emerge on reading the description and examples which follow.
Disclosed herein, therefore, is a cosmetic hair composition, comprising, in a cosmetically acceptable medium, isoeicosane and at least one nonsilicone fixing polymer.
Also disclosed herein is a cosmetic hair process, for instance, a process for fixing and/or holding a hairstyle using the compositions according to the present disclosure.
Yet another aspect of the present disclosure is the use of the compositions according to the present disclosure, for giving a sheen to the hair.
Isoeicosane is a hydrocarbon that is liquid at ambient temperature. For example, the commercial product sold under the name PERMETHYL 102 A by the company Bayer may be used.
The isoeicosane may be present in the composition in an amount ranging from 0.05 to 20% by weight, relative to the total weight of the composition, for instance from 1 to 10% by weight of the total weight of the composition.
For the purpose of the present disclosure, the term “fixing polymer” means any polymer that makes it possible to give shape to the hair and/or to maintain the shape.
The nonsilicone fixing polymers that may be suitable for use herein include, for example, those chosen from cationic, anionic, amphoteric and nonionic nonsilicone fixing polymers, and mixtures thereof.
The cationic nonsilicone fixing polymers that can be used according to the present disclosure may be chosen from polymers comprising primary, secondary, tertiary and/or quaternary amine groups that are part of the polymer chain or directly connected thereto, and which have a number-average molecular mass ranging from 500 to 5,000,000, such as from 1,000 to 3,000,000.

Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
