Oxidizing compositions comprising phosphonic acid chelant and conditioning agent and methods of treating hair

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 amines and mixtures thereof and a chelant selected from phosphonic acid chelants, salts thereof, derivatives thereof and mixtures thereof and methods of treating hair. 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 oxidative compositions containing phosphonic acid-type chelating agents and conditioning agents, and to methods of hair conditioning. The disclosed compositions and methods enhance deposition of conditioners on hair when subjected to oxidative treatments such as bleaching, oxidative dyeing, and perming. Background of the Invention [0002] Melanin is a natural pigment found in hair. Both melanin and hair-forming cells are naturally produced in the hair 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, the part of the hair that can be seen on the scalp. Hair can be schematically described as being composed of a central portion called the cortex containing melanin and an outer layer called the epidermis. It is the cortex that gives hair properties such as elasticity and curl. [0003] The hair shaft is formed from dead cells that cont...
