Thioglycolic Acid 80% (Japan) – Hair Perming & Straightening Agent for Professional Use

Thioglycolic Acid 80% (TGA-80, Japan Origin) is the industry-standard grade of the hair restructuring world’s most essential active — the workhorse concentration that powers the vast majority of professional perm solutions, hair relaxers, and straightening treatments globally. Where the 99% grade is the precision instrument for industrial synthesis and high-concentration formulation work, TGA-80 is the practical, formulation-ready grade that arrives pre-diluted to the concentration most commonly required in finished cosmetic systems, making it easier to handle, measure, and incorporate accurately into professional formulations.

Its Japanese origin is a meaningful quality signal in this category — Japanese-manufactured TGA is consistently recognized for its purity, low odor profile relative to other origins, and reliable batch-to-batch consistency, making it the preferred sourcing choice for professional cosmetic manufacturers who need predictable performance. The chemistry is the same well-established mechanism: the reactive thiol (-SH) group selectively breaks the disulfide bonds (S-S) in hair keratin, making hair pliable and reshapable, followed by neutralization to reform those bonds in the new configuration. Beyond hair restructuring, TGA-80 also finds application in depilatory formulations and as a reducing agent in chemical synthesis processes.

⚠️ Professional Use Only: Strong chemical — handle with appropriate protective equipment (gloves, goggles). Avoid direct skin/eye contact. Must be properly diluted, pH-adjusted, and formulated before use. Not for direct consumer use without formulation. Store in a cool, dry, well-ventilated area.
