Abstract

The present invention relates to a composition for dyeing keratin fibers, comprising at least (i) one or more copolymers derived from the polymerization of at least one crotonic acid monomer or crotonic acid derivative and of at least one vinyl ester monomer, (ii) at least one silicone, the total amount of silicone(s) ranging from 0.1% to 15% by weight relative to the total weight of the composition, and (iii) one or more pigments. The invention also relates to a dyeing process in which said composition is applied to keratin fibers, the operation optionally being followed by drying. The composition makes it possible to obtain temporary dyeing having the advantage of forming a transfer-resistant deposit, leaving the treated fibers individualized, with an improved cosmetic feel.

[0286] Protocol

[0287] Composition A is applied to locks of yak hair at a rate of 1 g of composition per gram of lock. The locks are then combed, dried with a hairdryer and then combed again.

[0288] Results: Cosmetic Feel Performance

[0289] The performance qualities in terms of cosmetic feel were evaluated on dried locks by five experts, in a blind test.

[0290] In 100% of the cases, the experts judged that composition A according to the invention afforded smooth locks with clearly individualized hair strands, having a pleasant cosmetic feel, especially good softness, good suppleness and absence of tackiness.

[0294] The locks are dried with a hairdryer and then combed.

[0295] The locks are then rubbed on a white cloth.

[0296] Results: Transfer-Resistance Performance

[0297] The performance qualities in terms of transfer resistance were evaluated by five experts, in a blind test, who visually evaluated the amount of pigment present on the white cloth after rubbing.

[0298] In 100% of the cases, the experts judged that composition A1 according to the invention, compared with compositions B1 and C1, led to a very markedly smaller amount of pigment present on the cloth than the amount deposited by compositions B1 and C1. Composition A1 according to the invention thus has better transfer-resistance properties than the comparative compositions B1 and C1.
