Lauroyl Lysine serves as a multi-functional biomimetic additive in cosmetic science, enhancing powder cohesiveness in mineral makeup while providing a velvet-like finish. In sunscreen formulations, it improves TiO2/ZnO dispersion for more even UV protection. The compound’s amino acid backbone makes it particularly suitable for sensitive skin formulations, where it reduces friction between particles without irritation. Pharmaceutical applications include its use as a gentle co-emulsifier in topical drug delivery systems.
