Abstract

A method for shaping keratin fibers comprising: providing a crosslinking composition, wherein the crosslinking composition comprises: an active agent, wherein the active agent is a carbonate ester; a cosmetically acceptable carrier; and applying the crosslinking composition to keratin fibers, mechanically shaping the keratin fibers with an appliance at a temperature of from about 50° C. to about 250° C. Also a related composition, use, kit and process.

Claims (7)

1. A method for mechanically straightening keratin fibres comprising:

(a) providing a crosslinking composition comprising 1, 3-dioxolan-2-one and arabinose, said composition having a pH from 10 to about 12 and

a cosmetically acceptable carrier;

(b) applying the crosslinking composition to keratin fibres, and mechanically straightening the keratin fibres with a hair straightening iron at a temperature of from about 80° C. to about 250° C.;

wherein said method is conducted without the use of thioglycolic acid or hydrogen peroxide; wherein said crosslinking composition is substantially free of: formaldehyde, derivatives of formaldehyde, formalin, and any compound that produces formaldehyde upon heating.

2. The method of claim 1 , wherein the crosslinking composition comprises a conditioning agent being the reaction product of: (a) an aminosilane; (b) polysiloxane; and optionally (c) a polyether.
