Problems solved by technology

[0008] However, the formulation of zinc salts in such leave-on care products poses many difficulties: among other things, the formulation of zinc salts, especially in the presence of cationic surfactants, leads to a general instability over time and therefore an unmarketable composition

Embodiment Construction

[0290] Compositions according to the invention

[0291] Amounts are indicated as weight percent of active material (AM) relative to the total weight of each composition.

[0292] For each composition, calculate the weight ratio (annotated as R) of the amount of one or more cationic surfactants to the amount of one or more zinc salts, and the ratio of the amount of one or more cationic surfactants to The weight ratio of the amount of one or more zinc elements (noted as R').

Abstract

The invention relates to a composition comprising a non-nitrogenous zinc salt and a particular cationic surfactant. The present invention relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one particular zinc salt and at least one cationic surfactant chosen from particular quaternary ammonium salts, in a specific weight ratio. Another subject of the invention relates to a process for treating keratin fibres, using such a composition, and to the use of such a composition, preferably in the form of a leave-on care product, for conditioning keratin fibresand protecting their artificial colour from fading.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 201180062177.9 with the filing date of December 19, 2011, entitled "Composition Containing a Non-Nitrogen-Containing Zinc Salt and a Specific Cationic Surfactant". technical field [0002] The present invention relates to a cosmetic composition comprising at least one specific zinc salt and at least one specific cationic surfactant in a specific weight ratio; and also to such a composition, preferably in the form of a leave-on care product Use for conditioning keratin fibers and protecting their artificial colors from fading. Background technique [0003] It is a known practice to dye hair with dye compositions comprising oxidation dye precursors, commonly referred to as oxidation bases. These oxidized groups are colorless or slightly colored compounds which, when combined with oxidation products, produce colored compounds via an oxidative condensation process. It is also known that the hu...
