    Ammonium Thioglycolate is an ammonium salt of thioglycolic acid.
    Ammonium thioglycollate is a key ingredient found in many hair care products, such as hair relaxers, perms, and straightening creams. It is a reducing agent that helps to break down the hair's disulfide bonds, making it easier to achieve desired hair texture, whether straight or curly.

    One of the main benefits of using ammonium thioglycolate is that it is less harsh on hair compared to other chemical treatments, reducing the risk of damage and breakage. It is also known for its ability to create long-lasting and beautiful curls or straight hair.

    When using ammonium thioglycolate, it is important to follow the instructions provided carefully to avoid over-processing the hair, which can lead to damage and breakage. The percentage of ammonium thioglycollate needed will vary depending on the desired results and the type of product being used.

    Overall, ammonium thioglycolate is a popular ingredient that can help achieve desired hair texture without causing excessive damage. It is important to choose high-quality hair products that contain ammonium thioglycollate and to follow the instructions carefully to achieve the best results.
    Ammonium thioglycolate, also known as perm salt, is the chemical compound with the formula HSCH2CO2NH4.

    Being the salt of a weak acid and weak base, ammonium thioglycolic acid exists in solution as an equilibrium mixture of the salt itself as well as the free carboxylic acid thioglycolic acid (HSCH2CO2H) and ammonia:

    HSCH2COO− + NH4+ \u21cc HSCH2COOH + NH3
    A solution containing ammonium thioglycolate contains a lot of free ammonia, which swells hair, rendering it permeable. The thioglycolic acid in the perm solution reduces the disulfide cystine bonds in the cortex of the hair. In a sense, the thioglycolate removes crosslinks. After washing, the hair is treated with a mild solution of hydrogen peroxide, which oxidizes the cysteines back to cystine. These new chemical bonds impart the structural rigidity necessary for a successful perm. The rigidification process is akin to the vulcanization of rubber, where commonly polysulfide linkages are used to crosslink the polymer chains. However, not as many disulfide bonds are reformed as there were before the permanent. As a result, the hair is weaker than before the permanent was applied and repeated applications over the same spot may eventually cause strand breakage.
    In the 2001 film Legally Blonde, law student Elle Woods wins her first case by her knowledge of the chemistry of ammonium thioglycolate (which she pronounces "ammonium thyglocolate"), something she claims "any Cosmo girl would have known."
    Ammonium thioglycolate, also known as perm salt, is the salt of thioglycolic acid and ammonia. It has the chemical formula HSCH2CO2NH4 and is used in hair perms.
    Ammonium thioglycolate, a salt of a weak acid and a weak base, exists in solution as an equilibrium mixture of the salt itself, thioglycolic acid and ammonia. HSCH2COO− + NH4+ \u21cc HSCH2COOH + NH3 thioglycolate can break the disulfide bond, capping one side with hydrogen and forming a new disulfide on the other side. RSH + R'SSR' \u21cc R'SH + R'SSR'
