Haefele, J.W. published the artcileProperties and reactions of hair after treatment with mercaptans of differing sulfhydryl acidities, HPLC of Formula: 1869-45-0, the publication is Proc. Sci. Sec. Toilet Goods Assoc. (1961), 31-9, database is CAplus.
cf. CA 54, 17233g.-Mercaptans of high sulfhydryl acidity have good hair-curling power and lower hair-damage potential than thioglycolic acid. However all compounds tested which have these properties are sensitizers. Thioglycolic acid has the great advantage that it is not a sensitizer. Three types of compounds represented by the following mercaptans were tested: thioglycolic acid, mercaptoethylacetamide, and thioglycolamide.
Proc. Sci. Sec. Toilet Goods Assoc. published new progress about 1869-45-0. 1869-45-0 belongs to amides-buliding-blocks, auxiliary class Trifluoromethylated Building Blocks, name is 2,2,2-Trifluoro-N-(2-mercaptoethyl)acetamide, and the molecular formula is C4H6F3NOS, HPLC of Formula: 1869-45-0.
