In the personal care industry, formulators are constantly seeking ingredients that deliver visible results without compromising on safety. Phenylethyl Resorcinol has emerged as a standout solution for skin brightening and evening skin tone, gaining traction in premium serums, creams, and lotions. Its ability to address hyperpigmentation and age spots has made it a favorite among brands targeting the lucrative anti-aging and whitening markets.

Phenylethyl Resorcinol is a synthetic resorcinol derivative, structurally related to natural compounds found in certain plants. It functions by inhibiting tyrosinase, the key enzyme in melanin production, thereby reducing excessive pigmentation. Unlike many traditional brightening agents, it offers a favorable safety profile and is well-tolerated in cosmetic formulations.

Our Phenylethyl Resorcinol is manufactured to the highest standards, with a purity of ≥99.0% (HPLC). It is a white to off-white crystalline powder, readily incorporated into emulsions and anhydrous systems. This grade is specifically designed for topical applications where efficacy and stability are paramount.

Product Overview & Composition

Phenylethyl Resorcinol is a single, pure chemical entity known for its potent tyrosinase inhibition. It is synthetically produced to ensure consistent quality and supply. The molecule features a resorcinol core with a 1-phenylethyl group at the 4-position, which enhances its lipophilicity and skin penetration compared to simpler resorcinol derivatives.

The product is characterized by its high purity and low impurity profile, making it suitable for sensitive skin applications. It is compatible with a wide range of cosmetic ingredients, including vitamins, peptides, and UV filters.
