Abstract

Compositions suitable for treating hair comprising an oxidizing agent, a conditioning agent selected from silicone materials, especially nonvolatile silicone and amino functionalised silicones, cationic surfactants, cationic polymers, alkoxylated amines and mixtures thereof and at least 1.6% of a chelant. The compositions of the invention are useful for depositing high amount of conditioning agent and reducing oxidative hair damage during oxidative treatment of hair such as oxidative hair dyeing and hair bleaching.

Description

field of invention [0001] The present invention relates to oxidizing compositions comprising chelating agents and conditioning agents and methods of treating hair. The disclosed compositions and methods enhance deposition of conditioning agents on hair when subjected to oxidative treatments such as bleaching, oxidative coloring, and perming. Background of the invention [0002] Melanin is a natural pigment found in hair. Both melanin and the cells that form the hair are produced naturally in the dermal papillae at the root of the hair. As new cells are produced, older cells are pushed up and out of the scalp to form the hair shaft, which is the part of the hair that can be seen on the scalp. Hair can be schematically described as consisting of a melanin-containing central part called the cortex and an outer layer called the cuticle. It is the cortex that gives the hair properties such as elasticity and curl. [0003] The hair shaft is formed from dead cells that contain ...
