개요
Based on the available data, the CIR Expert Panel concluded that ... Calcium Thioglycolate is safe for use in hair straighteners, permanent waves, tonics, dressings, and so forth, wave sets, other non-coloring hair products, and hair dyes and colors, as described in this safety assessment, at concentrations up to 15.2% (as Thioglycolic Acid). Hairdressers should avoid skin contact and minimize consumer skin exposure. Calcium Thioglycolate in depilatories is safe when formulated to be non-irritating under conditions of recommended use.

Color/FormWhite, crystalline powder
Solubility
Prismatic rod crystals. Odorless or faint mercaptan odor; somewhat astringent and fetid taste. Slowly loses H2O above 95 °C, darkens at 220 °C and partially fuses with decompn at 280-290 °C. Sol in water; very slightly sol in alcohol, chloroform; practically insol in ether, petr ether, benzene. Solns readily absorb CO2 from air, percipitating CaCO3. /Trihydrate/

Hazards Summary
Thioglycolates are toxic by ingestion because of their alkalinity; If pH >11, see treatment for Corrosives-Alkaline. In high-dose animal studies, chronic feeding of thioglycolate salts causes thyroid hyperplasia; [HSDB] An irritant; Targets the thyroid; [MSDSonline] See Calcium.

General Manufacturing Information
Acetic acid, 2-mercapto-, calcium salt (2:1): ACTIVE
WOOL-SHEARING PROPERTIES OF AQ CALCIUM THIOGLYCOLATE (2.8% SOLN) WAS INCR BY 70% BY DISSOLVING IN POTASSIUM CHLORIDE-SODIUM HYDROXIDE BUFFER OF PH 12.5.
CALCIUM THIOGLYCOLATE WAS ADDED TO DEPILATORY COMPOSITION, WHILE STIRRING, TO MAKE A HOMOGENEOUS CREAM.
A DISCUSSION WITH NO REF ON DEPILATORIES IN SEMILIQUID, CREAM & POWDER FORM CONTAINING CALCIUM THIOGLYCOLATE & WITH OR WITHOUT STRONTIUM HYDROXIDE.
A DEPILATORY COMPOSITION CONTAINING CALCIUM THIOGLYCOLATE TRIHYDRATE 8.0% REMOVED THE BEARDS OF UNSHAVEN NEGRO MALES IN APPROX 6 MIN WITH NO VISIBLE SKIN IRRITATION.
