PHENYLTHIOGLYCOLIC ACID

Description

Phenylthioglycolic acid, also known as phenylmercaptoacetic acid, is a potent organosulfur compound used in various skincare and cosmetic formulations. This multifunctional ingredient primarily serves as a reducing agent and chelating agent in hair care products, particularly in permanent wave solutions and hair straighteners. Its chemical structure allows it to break and reform disulfide bonds in hair keratin, enabling the reshaping of hair.

In skincare, phenylthioglycolic acid acts as an antioxidant and can help protect against free radical damage. It also demonstrates mild exfoliating properties, potentially aiding in the removal of dead skin cells and promoting cellular turnover. The compound's chelating abilities make it useful in formulations where metal ion contamination needs to be controlled, enhancing product stability and efficacy.

While effective, phenylthioglycolic acid requires careful concentration management due to its potential for skin irritation at higher levels. It's often used in conjunction with other ingredients to create synergistic effects in hair and skin treatments. Proper formulation and pH adjustment are crucial when incorporating this ingredient to maximize its benefits while minimizing potential adverse reactions.
