PHENYLPROPANOL

Description

Phenylpropanol is a versatile synthetic ingredient widely used in cosmetics and personal care products. This colorless liquid compound serves primarily as a preservative and antimicrobial agent, helping to extend the shelf life of skincare formulations by inhibiting the growth of bacteria, yeasts, and molds. Its molecular structure consists of a phenyl group attached to a propanol chain, giving it both hydrophobic and hydrophilic properties.

In addition to its preservative function, phenylpropanol offers mild fragrance properties, contributing a subtle, pleasant scent to products. It also acts as a solvent, aiding in the dissolution of other ingredients and enhancing the overall stability of formulations. This multifunctional ingredient is particularly valued for its effectiveness at low concentrations, typically used at levels between 0.3% to 1% in skincare products.

Phenylpropanol is generally well-tolerated by most skin types and is considered a safer alternative to some traditional preservatives. It works synergistically with other preservatives, allowing formulators to create broad-spectrum preservation systems with reduced concentrations of individual components. This ingredient is approved for use in cosmetics by regulatory bodies worldwide, including the European Union and the United States FDA.
