Lactic Acid 60% Liquid(CAS 79-33-4)
Cosmetic Grade Lactic Acid 60% Liquid is a natural fermented alpha hydroxy acid (AHA) with a standard 60% high-purity aqueous solution. As one of the mildest and most skin-friendly fruit acid ingredients, lactic acid is consistent with the natural acidic environment of human skin.
Different from high-irritation glycolic acid, it features slow penetration, mild exfoliation, low irritation and strong moisturizing performance. It can gently dissolve the adhesion of aged dead keratin, promote natural skin renewal, improve rough, dull and uneven skin texture, and present smooth and translucent skin.
In formula application, Lactic Acid serves as an efficient pH regulator to balance system acidity and alkalinity, optimize formula stability, and improve the efficacy release of active ingredients. With natural mildness, dual effects of exfoliation and moisturizing, and wide formula compatibility, Lactic Acid 60% is an essential basic functional raw material for gentle skin renewal, brightening skincare and cosmetic pH adjustment systems.
