Thickened hair colourant and bleaching compositions

Abstract

The present invention relates to hair colouring and hair bleaching compositions comprising a source of carbonate ions, at least one oxidizing agent and a specified gel network thickener system comprising a specified ternary surfactant system. The compositions surprisingly provide improved hair colourant and bleaching compositions which deliver improved lift, lightening and colour delivery whilst minimizing damage which are easy to manufacture and have long shelf life stability.
