Chlorphenesin, a diol with a 4-chlorophenyl group, is a fine white to pale-cream-colored crystalline substance, noted for its slightly phenolic odor and bitter taste. It is primarily used in the preservation and stabilization of cosmetics and pharmaceuticals. By integrating chlorphenesin into existing preservation systems, the overall preservative performance is significantly enhanced, as validated by kill-rate studies using various organisms. This compound serves as a potent and versatile anti-bacterial and anti-fungal agent, augmenting the efficacy of other preservatives. When combined with agents such as potassium sorbate, sodium benzoate, and parabens, chlorphenesin effectively extends product shelf-life and improves usage periods.
