영문 초록

In this study, the relation of the preservation efficacy reduction with methyl paraben of parahydroxybenzoic acid derivatives was investigated using the dialysis membrane method with tween-80 of surfactant and TiO₂/Talc of inorganic powder meterial from emulsion system. It was found that the preservation efficacy of tween-80 and TiO₂/Talc from emulsion system was reduced due to the adsorption of methyl paraben. According to the microbe test, In case of tween-80, MBC appeared in 0.19 w/v% and in case of TiO₂/Talc, MBC appeared in 0.22w/v% / 0.23w/v%. In general, the equation of Talc s adsorption weight(A·W) has a tendency to show in A·W=11.5C0.745
