Calcium Hydroxymethionine
What is Calcium Hydroxymethionine?
Calcium Hydroxymethionine is the calcium salt of 2-hydroxy-4-(methylthio)butanoic acid, a synthetic derivative structurally similar to the amino acid methionine but with a hydroxy group replacing the amino group for enhanced stability. This chemical modification allows it to function effectively in cosmetic formulations without degradation. Primarily categorized as a skin and hair conditioning agent, it appears in moisturizers, lotions, creams, and hair conditioners. In products, it works as a humectant by drawing moisture to the skin and hair, while also providing miscellaneous conditioning benefits that enhance texture and manageability. Its ionic calcium component may contribute to formulation stability. Derived through chemical synthesis, it offers a stable alternative to natural amino acids in personal care items, supporting hydration and smoothness without altering pH significantly.
