Phenylpropanol

What is Phenylpropanol?

Phenylpropanol, chemically known as 3-phenylpropan-1-ol, is a colorless liquid aromatic alcohol produced synthetically from petrochemical sources or via fermentation processes mimicking natural plant-derived versions found in roses and honey. In cosmetic formulations, it primarily serves in the fragrance category, imparting a mild, rosy, floral scent that enhances product appeal. As a solvent, it aids in dissolving lipophilic and hydrophilic ingredients, optimizing texture and active delivery in emulsions, serums, and cleansers. Its masking role neutralizes off-odors from other components, ensuring a pleasant sensory profile. With a low molecular weight, it evaporates slowly, contributing to long-lasting fragrance without greasiness, and supports formulation clarity in water-based systems.
