    Product Description

    Chlorphenesin is a synthetic preservative.1 It is active against various strains of Pseudomonas and Burkholderia when used in combination with methylparaben (MICs = 5-10 g/L). Chlorphenesin (0.001-0.1%) is cytotoxic to immortalized human meibomian gland epithelial cells.2 It prevents homologous passive cutaneous anaphylaxis in rats (ID50 = 220 mg/kg).3 Formulations containing chlorphenesin have been used as biocides in cosmetic products.

    WARNING This product is not for human or veterinary use.
