Abstract: 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 composition addresses the aforementioned disadvantages by providing a hair colour composition comprising: (a) Gossypetin; and either (b1) A combination of a peroxidase with either a hydrogen peroxide generator or hydrogen peroxide, or (b2) a laccase; wherein the composition has a pH of 4.5 to 7.0, preferably less than or equal to 6.0.

Abstract: The present invention provides improved processes for the synthesis of 1,4-ditosyl-1,4,7-triazacyclonone, comprising deprotecting a compound of formula (C): wherein P is tosylate or arylsulfonate, with an acidic medium to form 1,2-bis(1,4,7-triazacyclonon-1-yl)-ethane; and subsequently adding formaldehyde and formic acid to the acidic medium to form 1,2-bis-(4,7-dimethyl-1,4,7-triazacyclonon-1-yl)-ethane (Me4-DTNE). The syntheses of intermediates are also disclosed.
