Pantolactone
What is Pantolactone?
Pantolactone is the cyclic lactone ester derived from pantothenic acid, a water-soluble B vitamin vital for cellular metabolism. Synthetically produced for stability, it features a five-membered ring structure that opens upon skin contact, releasing active components. Commonly found in moisturizers, serums, creams, and hair products within the skincare and personal care categories, it acts as a humectant by binding water molecules from the air and deeper skin layers to the stratum corneum. This mechanism enhances moisture retention, softens texture, and improves product spreadability without greasiness. Its mild nature suits sensitive formulations, contributing to overall skin feel and barrier support in daily routines.
