Description
Phenylethyl resorcinol (CAS 85-27-8), also known commercially as SymWhite 377 or phenethyl resorcinol, is a synthetic resorcinol derivative with the molecular formula C14H14O2. It is registered under EC number 480-070-0 and classified within pharmaceutical intermediates, with no assigned E-code.
In personal care formulations, phenylethyl resorcinol functions as a skin-brightening active by inhibiting tyrosinase, the enzyme responsible for melanin synthesis, making it a targeted ingredient in hyperpigmentation treatments. It also acts as an antioxidant and UV absorber in polymer systems, where it interrupts oxidative chain reactions and absorbs UV radiation to delay thermal and photodegradation.
This material is supplied as a solid and is subject to REACH registration requirements within the EU. Procurement teams should confirm supplier compliance documentation, including safety data sheets aligned with current CLP regulations. The applicable HS code for customs classification is 2907290090.
