Abstract
|
|
|
The rate of decomposition of calcium thioglycollate in aqueous solution was shown to increase with increasing temperature and with diluting concentration of calcium thioglycollate. The effect of additive on oxidation rate of calcium thioglycollate was studied to prepare the more stable depilatory formula using additives, such as thiourea, mannitol, sodium thiocyanide, nicotinamide, triethanolamine and ethylenediamine. In all cases, the rate of oxidation was reduced when the additive was present in the solution, among them triethanolamine and ethylenediamine inhibited the decomposition rate remarkably. It is assumed that the decomposition reaction in aqueous solution is pseudo-first order reaction.
