Overview
Benzyl alcohol (CAS 100-51-6 ), also known as phenylmethyl alcohol, is an aromatic alcohol used across pharmaceuticals, personal care, and industrial manufacturing as a solvent and preservative.
Its low volatility and broad solubility profile make it a practical choice where controlled evaporation and compatibility with diverse formulation systems are procurement priorities for manufacturers.
In pharmaceuticals, it functions as a bacteriostatic preservative in injectable formulations and as a solvent for active ingredients in topical preparations. It is a versatile chemical intermediate.
Personal care formulators use it as a preservative in rinse-off and leave-on products, and as a fragrance component with a mild scent, listed under FEMA 2137 for flavor applications.
Industrial coatings and printing inks rely on it as a slow-evaporating solvent that aids pigment dispersion and improves film formation. In adhesives, it acts as a reactive diluent and processing solvent.
Benzyl alcohol is supplied as a clear liquid in drums, IBCs, and bulk tankers. Standard grades include USP , BP , Ph. Eur. , and FCC , covering both regulated and industrial requirements.
Purity levels typically range from 99% for pharmaceutical and food-grade material to lower specifications for technical applications. This ensures compliance with global safety and quality standards.
