Magnesium Lactate
What is Magnesium Lactate?
Magnesium lactate is the magnesium salt derived from lactic acid, an alpha-hydroxy acid produced through bacterial fermentation of carbohydrates or via chemical synthesis. In cosmetics, it falls under buffering agents, keratolytics, and skin conditioning materials, commonly appearing in creams, lotions, serums, and exfoliants. It works by donating or accepting ions to stabilize product pH, ensuring formulation integrity over time. In its keratolytic capacity, the compound subtly disrupts corneocyte adhesion in the stratum corneum, facilitating natural cell turnover for refined texture. As a skin conditioner, it interacts with skin lipids and water to promote suppleness and hydration retention. This multifunctional ingredient integrates seamlessly into leave-on and rinse-off products, leveraging its neutral profile for broad compatibility without altering sensory attributes significantly.
