Thioglycolic acid corresponding disulfide (2-[(carboxymethyl)disulfanyl]acetic acid or dithiodiglycolic acid): Thioglycolic acid, usually as its dianion, forms complexes with metal ions. Such complexes have been used for the detection of iron, molybdenum, silver, and tin. Thioglycolic acid reacts with diethyl acetylmalonate to form acetylmercaptoacetic acid and diethyl malonate, the reducing agent in conversion of Fe(III) to Fe(II). Scientist David R. Goddard, in the early 1930s, identified TGA as a useful reagent for reducing the disulfide bonds in proteins, including keratin (hair protein), while studying why protease enzymes could not easily digest hair, nails, feathers, and such. He realized that while the disulfide bonds,
Hair volumizer Hair volumizer Hair volumizers are used to temporarily add volume, body, and shine to thin or flat hair. Hair volumizers are used by both men and women. Men turn to hair volumizers to make their hair look more dense. Volumizers come in many forms such as shampoos, conditioners, sprays, pomades and lotions. Hair volumizers contain humectants, which work by attracting moisture from the surrounding areas to the hair strand, thereby swelling the hair and making it look thicker. Various polymers present in the volumizer coat the hair strand, making it look thicker and shiny. Shampoo and conditioner forms of the
