Embodiment 1

[0575] Prepare the following compositions:

[0576] Isopropanol 70g

[0577] Cyclopentasiloxane, marketed under the name Dow Corning DC245 Fluid 20g

[0578] Dimethicone / urea copolymer, by Wacker according to the standard Sell ​​10g

[0579] 0.2 g of the composition is applied to a lock of clean, dry hair weighing 1 g. After a leave-in time of 2 minutes, the locks were dried with a hair dryer for 2 minutes. The hairs of the lock of hair obtained are separated and coated. The coating is durable against shampoo washing.

Embodiment 2

[0581] Prepare the following compositions:

[0582] Isopropanol 67g

[0583] Cyclopentasiloxane, marketed under the name Dow Corning DC245 Fluid 20g

[0584] Dimethicone, sold as standard by Dow Corning Dow Corning 200 Fluid 60000cs 3g

[0585] Dimethicone / urea copolymer, by Wacker according to the standard Sell ​​10g

[0586] 0.2 g of the composition is applied to a lock of clean, dry hair weighing 1 g. After a dwell time of 2 minutes, the tress is dried with a hair dryer for 2 minutes. The hairs of the lock of hair obtained are separated and coated. The coating is durable against shampoo washing.

Embodiment 3

[0588] Prepare the following compositions:

[0589] Isopropanol 50g

[0590] Cyclopentasiloxane, marketed by Dow Corning under the name DC245 Fluid 39g

[0591] Aerosil 200 Silica 1g

[0592] Dimethicone / urea copolymer, by Wacker according to the standard Sell ​​10g

[0593] 0.2 g of the composition is applied to a lock of clean, dry hair weighing 1 g. After a dwell time of 2 minutes, the tress is dried with a hair dryer for 2 minutes. The hairs of the lock of hair obtained are separated and coated. The coating is durable against shampoo washing.

Abstract

The invention provides a use of a polysiloxane / polyurea block copolymer for hair treatment. This polysiloxane / polyurea block copolymer is used for the hair treatment, especially for the covering of individual hair with the block copolymer, and a cosmetic composition is provided by containing the polysiloxane / polyurea block copolymer, at least one volatile non-silicone organic solvent and at leastone silicone compound showing <100 cSt viscosity. Such the composition enables to obtain the covering of individual hair, durable especially to the shampoo treatment.

Description

technical field [0001] The subject of the present invention is the use of a cosmetic composition using polysiloxane / polyurea block copolymers for the treatment of hair, in particular for the coating of personal hair. Background technique [0002] Hair is often damaged and brittle due to external atmospheric factors, such as light and harsh weather, and due to mechanical or chemical treatments, such as brushing, combing, bleaching, ironing and / or dyeing. The result of these is hair that is difficult to manage; in particular, difficult to detangle or style, and hair, even thick hair, to maintain an aesthetically appealing style due to the lack of vigor, strength and elasticity of the hair. [0003] Therefore, in order to overcome these, it is now common practice to use styling products which condition the hair by, inter alia, providing body, volume or strength to the hair. [0004] These styling products are generally hair cosmetic compositions containing one or more polymers...
