Reference Information
| Introduction | calcium mercaptoacetate is a white crystalline powder, soluble in water, slightly soluble in alcohol, with special odor of mercapto compounds, metal ions such as iron and copper turned red. |
| apply | calcium thioglycolate (1:1) as a depilatory for skin or leather. Calcium thioglycolate is now the main depilatory agent, it through the destruction of the hair structure of disulfide bonds and polypeptides, and its reduction in alkaline conditions, so that the mechanical strength of the hair becomes low, because of its different usage, can make the hair from soft to broken, in the Perm class, hair removal cosmetics have been widely used. |
| preparation | sodium chloroacetate reacts with thiourea to obtain isothiourea acetic acid, and then reacts with calcium hydroxide to obtain product: HN = C(NH2)-S-CH2COOH Ca(OH)2 → CaSC2H2O2 · 3H2O H2NCN |
| Use | used as reducing agent, depilatory agent |
