Investigation of Surfactants and Preservatives Being Used in Korean Fundamental Cosmetics

Surfactants and preservatives are very important components in the safety issues of cosmetics. This investigation focuses on the variation of surfactants and preservatives used in Korean cosmetics. Currently, polyethylene glycol (PEG)-free surfactants are widely used as oil/water (O/W) emulsifiers, however, PEG-attached surfactants are still being used as W/O emulsifiers and solubilizing agents. Paraben preservatives have disappeared in Korean cosmetics formulations. Instead, 1,2-hexanediol, ethylhexylglycerine, and phenoxyethanol have replaced these. The safety promotion of these surfactants and preservatives will make Korean cosmetics one of the safest in the world.
