Abstract
Present invention relates to a non-aqueous leave-in conditioning composition for hair, especially for strongly damaged hair by chemical processes such as permanent shaping, oxidative coloration and bleaching. Accordingly, conditioning compositions of present invention comprise one or more cyclomethicone at a concentration of at least 50% by weight calculated to total composition, and at least one dialkyl carbonate.
Claims13
A method for improving elasticity of hair, the method comprising
- applying a composition to the hair thereby increasing the elasticity of the hair, wherein the composition comprises a single-phase, transparent, non-aerosol, non-aqueous composition comprising one or more cyclomethicone of the formula
- where n is a number between 3 and 7, at a concentration of between 55 to 90% by weight, calculated to the total composition, and at least one dialkyl carbonate of the formula
- R1OC(O)OR2
- where R1 and R2 are independent from each other linear or branched saturated or unsaturated alkyl chains with 6 to 22 C atoms, wherein the at least one dialkyl carbonate is present at a concentration between 0.1 and 20% by weight, calculated to the total composition.
