A new ointment base (PEN 32) consisting of polyalcohols prevents the growth of bacteria and fungi in concentrations above 25% (mg/mg). In a concentrated form the ointment base exhibited excellent bactericidal and fungicidal effects in vitro. This property enables the ointment base to be employed without preservatives.
一种由多元醇组成的新型软膏基质（PEN 32）在浓度高于25%（毫克/毫克）时可抑制细菌和真菌的生长。以浓缩形式存在时，该软膏基质在体外表现出优异的杀菌和杀真菌效果。这一特性使该软膏基质无需添加防腐剂即可使用。
