Magnesium Citrate

What is Magnesium Citrate?

Magnesium Citrate is the magnesium salt of citric acid, a simple organic compound produced through chemical synthesis or derived from natural citric acid sources like citrus fruits. In cosmetics, it appears in leave-on moisturizers, shampoos, and conditioners within concentrations typically under 1%. It functions primarily as a skin conditioning agent by forming a protective film that helps retain moisture and enhances skin flexibility. For hair products, it reduces friction between strands, improving texture and ease of styling. Additionally, its mild buffering properties help stabilize product pH for better stability and comfort on application. This multifunctional ingredient supports overall product performance without adding weight or greasiness.
