Ammonium glycolate, with the chemical formula NH4+(C2H3O3)-, is a compound formed by the neutralization of glycolic acid with ammonia. It is an ammonium salt of glycolic acid, a smallest alpha-hydroxy acid (AHA) known for its usage in various skincare and industrial applications. This compound combines the properties of glycolic acid, known for its exfoliating, moisturizing, and skin-conditioning effects, with the stabilizing and neutral properties of ammonium.

In skincare and cosmetic formulations, ammonium glycolate is valued for its ability to penetrate the skin easily, helping to exfoliate the outer layer of dead skin cells, stimulate new growth, and improve the skin’s texture and appearance. It’s often found in products like skin creams, lotions, and peels, where it helps to reduce the appearance of fine lines, wrinkles, and other signs of aging by promoting cell turnover.

Beyond its cosmetic use, ammonium glycolate can also serve various industrial purposes. Its applications may include roles as a buffering agent, a neutralizer, or in the production of certain plastics and fibers. Its efficacy as an intermediate in chemical synthesis and its utility in pH adjustment processes highlight its versatility in industrial contexts.

In all its applications, the safety and concentration of ammonium glycolate are crucial. In cosmetic formulations, it is used in concentrations that are effective yet gentle enough to minimize potential irritation, considering the sensitive nature of human skin. Regulatory bodies such as the FDA (Food and Drug Administration) and the EU’s Cosmetic Directive oversee its usage in cosmetic and personal care products to ensure consumer safety.
