The relative cytotoxicity of personal care preservative systems in Balb/C 3T3 clone A31 embryonic mouse cells and the effect of selected preservative systems upon the toxicity of a standard rinse-off formulation

Theses studies have provided a standardised assessment of the cytotoxicity of cosmetic preservatives and demonstrated that preservation of a rinse-off formulation at recommended addition levels is unlikely to affect the cytotoxic profile.
