Description
Undecylenoyl phenylalanine (CAS 175357-18-3) is a lipopeptide active ingredient derived from phenylalanine and undecylenic acid, commercially known under trade names including Sepiwhite, Sepiwhite MSH, and Sepiwhite MSH powder. It carries no assigned E-code. The compound is registered under EC number 446-800-7 with the molecular formula C20H29NO3.
In personal care formulations, undecylenoyl phenylalanine functions as a skin-brightening agent by competitively inhibiting the melanocyte-stimulating hormone (alpha-MSH) receptor, thereby reducing melanin synthesis at the cellular level. It is incorporated into facial serums, spot-correction creams, and UV-aftercare products where controlled pigmentation management is required.
The ingredient is supplied in powder form and is subject to REACH registration requirements for EU market access. Procurement teams should confirm supplier documentation including Safety Data Sheets and Certificate of Analysis. Packaging formats vary by supplier; quantities typically range from laboratory-scale to bulk industrial supply.
