Abstract
The presently claimed invention relates to hair colouring formulations comprising 2-amino-1-Propanol (2A1P/Alanilol) as an alkalizing agent. The compositions of the presently claimed invention provide a series of desirable properties to the user such as a pleasant low chemical odour and a high level of hair bleaching with an acceptable damage profile. The compositions of the presently claimed invention further enable formulators to deliver a wider range of shades or colour formulations by reducing the off-toning adducts of oxidative dyes.
