Methylsilanol Hydroxyproline Aspartate

What is Methylsilanol Hydroxyproline Aspartate?

Methylsilanol Hydroxyproline Aspartate is a synthetic organosilicon compound where a methylsilanol group is linked to hydroxyproline and aspartate amino acids. Developed for cosmetic formulations, it belongs to the silanol family, often incorporated into creams, serums, and conditioners. In products, it functions by depositing a lightweight film on the skin or hair surface, which helps retain moisture, supports barrier integrity, and imparts a silky feel. The amino acid components contribute to its humectant-like action, drawing water to the skin while the silanol provides emollience and antistatic benefits, particularly beneficial in hair care to minimize friction and improve combability without greasiness.
