The preservative systems of unused, anhydrous mascaras were challenged periodically with microorganisms, using a modified membrane procedure. Shelf life of preservative activity against Pseudomonas aeruginosa varied for different brands from as little as 1 month to over 36 months. Generally, P. aeruginosa grew in mascaras after the mascaras were challenged first with Staphylococcus epidermidis or Candida albicans.
采用改良的膜过滤法，定期用微生物对未开封的无水睫毛膏的防腐剂系统进行挑战试验。不同品牌的睫毛膏对铜绿假单胞菌的防腐活性保质期差异很大，短至1个月，长至超过36个月。一般来说，睫毛膏先用表皮葡萄球菌或白色念珠菌进行挑战试验后，铜绿假单胞菌会在睫毛膏中生长。
