Frequently Asked Questions
What is 4-butylresorcinol, and what is it used for?
4-Butylresorcinol (CAS 18979-61-8) is a 4-alkyl-substituted resorcinol, a dihydric phenol. It is supplied as a cosmetic ingredient for skin-brightening and even-skin-tone formulations, where it acts as a tyrosinase inhibitor, and as a specialty alkylresorcinol building block.
What is another name for 4-n-butylresorcinol?
It is also written as 4-butylresorcinol, 4-n-butylresorcinol, and butylresorcinol, and is the resorcinol bearing a butyl group at the 4-position. All refer to CAS 18979-61-8.
How does 4-butylresorcinol differ from plain resorcinol?
4-Butylresorcinol is resorcinol substituted with a four-carbon butyl chain at the 4-position, whereas resorcinol is the unsubstituted dihydric phenol. The alkyl chain changes its solubility and gives it its tyrosinase-inhibiting function in cosmetic formulations.
What is the CAS number and molecular formula of 4-butylresorcinol?
4-Butylresorcinol has CAS number 18979-61-8 and molecular formula C10H14O2, classified in the Specialty Additives family. Its HS classification is 2907.29 (polyphenols; phenol-alcohols, other).
