Tetrapéptido-12 de miristoilo

Synonyms: Myristoyl Tetrapeptide-12, N-Myristoyl Tetrapeptide-12, Myristoyl Tetrapeptide-12 (INCI), CAS 959610-54-9

Myristoyl Tetrapeptide-12 is a synthetic lipopeptide consisting of a tetrapeptide backbone acylated with myristic acid at the N-terminus. The sequence—typically comprising glycine, histidine, and lysine residues—is designed to mimic the active site of human parathyroid hormone-related protein (PTHrP), a natural regulator of melanogenesis. This modification enhances lipophilicity and skin penetration, making it a valuable active in cosmetic formulations aimed at pigmentation control.

Since its introduction, Myristoyl Tetrapeptide-12 has gained attention as a non-hydroquinone alternative for hyperpigmentation. It operates by interfering with tyrosinase activity and melanocyte-stimulating hormone (MSH) signaling, thereby reducing melanin synthesis. Unlike conventional whitening agents, it does not cause cytotoxicity to melanocytes, offering a gentler approach to skin lightening.

The peptide is produced via solid-phase peptide synthesis, followed by myristoylation and high-performance liquid chromatography (HPLC) purification. It is supplied as a white to off-white powder, standardized to ≥98% purity, and is compatible with a wide range of cosmetic delivery systems, including emulsions, serums, and gels.
