Blood Chemistry of Domestic Rabbits Exposed to an Oxidative Hair Dye

A Review of Aspects of Oxidative Hair Dye Chemistry with Special Reference to N-Nitrosamine Formation

This review discusses a new aspect to the safety profile of oxidative hair dyes using data already in the public domain. These dyes contain secondary amines that are capable of forming potentially carcinogenic nitrosamine derivatives when exposed to atmospheric pollution. Numerous scientific articles confirm the existence of secondary amines in hair dyes (and their intermediates), the possibili...

OPINION ON Intermediates and reaction products of oxidative hair dye ingredients formed during hair dyeing

Hair dye poisoning.

Hair dye ingestion is an uncommon form of poisoning in the west, however, in some parts of the world such as East Africa and Indian Sub-continent it is not uncommon. The main component of hair dye causing toxicity is Paraphenylenediamine (PPD). This compound has been found to cause angioneurotic edema, rhabdomyolysis and renal failure. We present a case of hair dye poisoning who presented with ...

The Chemistry of Hair

MR. J. PICKTHALL.' When talking of H.L.B. values, the speaker has referred to the oil solubility of calcium soaps. Are these soaps in fact oil soluble in the sense that we are considering ? In discussing the emulsifying action of the calcium soaps, the speaker has compared them with glyceryl distearate and aluminium stearate. Glyceryl distearate is indeed oil soluble but commercial aluminium st...
