INCI Name: HEXYLRESORCINOL Molecular Formula: C12H18O2 Molecular Weight: 194.27 Appearance: White to pale orange or pale pink powder Purity: 98% CAS NO.: 136-77-6 EINECS No.: 205-257-4 Application: cosmetics and skin care products Supplier: ZHENYIBIO Hexylresorcinol is a chemically synthesized component and a derivative of resorcinol, also called 4-hexyl resorcinol, generally abbreviated as 4-HR. Hexylresorcinol is the most well-known alkyl resorcinol Phenol derivatives are excellent inhibitors of polyphenol oxidase.In terms of whitening,they can inhibit the activity of tyrosinase and block the production of melanin. In addition,they can prevent UVA,UVB damage,and anti-wrinkle effects.Hexylresorcinol is the safest choice among alkyl resorcinol derivatives.It is safer and more effective than hydroquinone and kojic acid.It is one of the most powerful whitening ingredients.It can inhibit the activity of tyrosinase. ,Block the production of melanin.In addition,it can prevent UVA, UVB damage, and anti-wrinkle effects.In vivo experiments have confirmed that 0.5% hexylresorcinol has the same whitening effect as 2% hydroquinone within 8 weeks.
