    摘要: A process is disclosed for bleaching of a substrate which includes adding a molecular oxygen activating system to an aqueous wash liquor and bleaching the substrate with the molecular oxygen activating system in the aqueous wash liquor. Significant substrate cleaning results can be obtained by molecular oxygen obtained from air even in the absence of any usually applied active oxygen ingredients such as perborate or percarbonate.

    摘要: Hair colourant formulations fall into three main categories designated permanent, semi-permanent and temporary. Permanent hair colourant formulations are oxidative dye systems and generally contain paraphenylene diamine (PPD) and resorcinol, both of which have been shown to cause sensitisation and mutagenicity. Furthermore, severe oxidising conditions are required which in themselves cause skin irritation and sensitization as well as hair fibre damage. The inventive method addresses the aforementioned disadvantages by providing a method of colouring hair fibres, the method comprising the step of applying a hair colour composition, the hair colour composition comprising: (a) (+)-Catechin, (−)-catechin, (+)-epicatechin, (−)-epicatechin or mixtures thereof; (b) A hydrogen peroxide generator or hydrogen peroxide; and (c) A peroxidase and; wherein the composition has a pH of 4.5 to 7.0, preferably less than or equal to 6.0.
