Description

The present disclosure relates to novel cosmetic hair compositions comprising at least one tridecyl trimellitate and at least one isoeicosane. It is also directed towards processes, for example, a process for treating the hair by applying the compositions, and also a process for giving the hair sheen by applying the compositions.

The use of oils of the benzoic triacid triester type, such as tridecyl trimellitate, is well known for the formulation of numerous cosmetic products comprising a fatty phase.

It is described in patent application EP-A-0 792 637 for the preparation of lipsticks. It is also mentioned in patent application EP-A-0 194 055 for the preparation of anhydrous cosmetic formulations free of mineral oil. In U.S. Pat. No. 4,940,577, this type of oil constitutes the fatty phase of transparent microemulsions of the water-in-oil type with a low water content, which may be used as antisun products.

There is a need for hair products that can give the hair long-lasting sheen, without making the hair look too greasy. This need is not addressed by the compositions of the prior art.

In one embodiment, the Applicant has discovered, surprisingly, that compositions comprising at least one tridecyl trimellitate and at least one isoeicosane provide the hair with at least one of strong, long-lasting sheen and a smooth feel.

The Applicant has also found that in some embodiments these compositions adhere well to the hair and have good cosmetic properties.

The Applicant has also discovered that these compositions, in some embodiments, can be formulated in an alcoholic medium.

One non-limiting embodiment of the present disclosure is a cosmetic hair composition, wherein the composition comprises, in a cosmetically acceptable medium, at least one tridecyl trimellitate and at least one isoeicosane.

Another subject of the invention relates to a cosmetic hair process, such as a process for treating the hair using the compositions disclosed herein.

A subject of the invention is also a process for giving the hair sheen by applying the compositions disclosed herein to the hair.

Tridecyl trimellitate is an oil having the following formula:

• • lsoeicosane is a hydrocarbon that is liquid at room temperature. The commercial product sold under the name Permethyl 102 by the company Bayer may, for example, be used as the isoeicosane disclosed herein.

In one embodiment, the individual concentrations of tridecyl trimellitate and of isoeicosane range from 0.01% to 15%, such as from 1% to 10% by weight relative to the total weight of the composition.

In a further embodiment, the mixture comprising at least one tridecyl trimellitate and at least one isoeicosane is present in the composition in an amount ranging from 0.05% to 20% by weight relative to the total weight of the composition, such as ranging from 5% to 10% by weight relative to the total weight of the composition.

The tridecyl trimellitate/isoeicosane weight ratio, may, for example, range from 100 to 0.01, such as from 10 to 0.1. The ratio may range, for further example, from 0.7 to 1.3.
