Isoamyl Laurate

What is Isoamyl Laurate?

Isoamyl laurate is a synthetic ester formed from isoamyl alcohol, often sourced from fermented plant materials, and lauric acid derived from coconut or palm kernel oils. In cosmetics, it serves primarily as a multifunctional ingredient in lotions, creams, serums, and fragranced products. Chemically, its branched structure provides a dry, non-greasy feel similar to silicones but from natural-derived origins. It functions by mimicking natural skin lipids to lubricate the surface, reducing friction for smoother application, and acting as a solvent to disperse and stabilize fragrance compounds, ensuring even scent release. This makes it ideal for lightweight formulations where a silky, quick-absorbing quality is desired without heaviness.
