Lactobionic Acid

Lactic acid (lactobionic acid) is a type of lactonic acid that is often found in cosmetic products for its skin benefits and properties as a preservative. It is a polyhydroxy acid (PHA) that is less irritating than other acids such as alpha-hydroxy acids (AHA) or beta-hydroxy acids (BHA), making it an ideal choice for sensitive skin. Lactobionic acid is also known as galactosylgluconic acid.

Lactobionic acid is widely used in cosmetic products, especially in products designed to exfoliate and moisturize the skin. It may also be called PHA or polyhydroxy acid, which is a popular ingredient in many cosmetic products for its ability to gently exfoliate the skin without causing irritation. It is also a powerful antioxidant that helps protect the skin from the damaging effects of free radicals. Outside of the cosmetic industry, lactobionic acid is also used in the food industry as a stabilizer or emulsifier. It is also used in the medical field, for example in ophthalmology as a component of the solution in corneal transplants.
