LAC

About LAC

Whole cow's milk — nature's original moisturiser. Rich in lactic acid, proteins, and fats that soften, hydrate, and gently exfoliate skin. Used since Cleopatra's time.

Detailed Analysis

Lac (CAS 8049-98-7) is whole cow's milk, used as a cosmetic ingredient for its skin conditioning properties. It contains a complex mixture of proteins (casein, whey), fats, lactose, lactic acid, vitamins (A, D, E), and minerals. Lactic acid provides gentle exfoliation as an alpha-hydroxy acid, while milk proteins and fats moisturise and soften. Milk baths have been used for skin conditioning since antiquity. No GHS hazards or EU restrictions apply. The primary concern is potential allergic reaction in individuals with milk protein allergy or lactose sensitivity.
