随着社会的不断发展，经济的不断提高，关于化妆品方面的检验标准也随之提高。《化妆品卫生规范》（2007年版）中没有规定具体方法来中和防腐剂，但这一问题现在普遍存在，可以借鉴食品、药品微生物检验中的相关方法。《化妆品卫生规范》（2007年版）中规定采用蒸馏水配制微生物检验用培养基。现在多数实验室都购买成品培养基，按说明书称量后加蒸馏水即可，往往忽略了调整培养基的pH值。具体操作时，应重点把握TTC溶液的量，过多的TTC溶液将会抑制微生物细菌的生长，因此，添加适量的TTC溶液对于检验工作是十分必要的，可以有效推动化妆品微生物检验工作的有序进行。“,”With the continuous development of society,economy,about cosmetic inspection standard increases.《Cosmetics health standards》(2007 edition)there are no rules in the specific methods to neutralize preservatives,but now the problem is widespread,and can be drawn lessons from the food and drug microbiological methods《Cosmetics health standards》(2007 edition)specified in the mix microbiological media using distil ed water Most laboratories are now buying finished product medium,according to the manual weighing after adding distil ed water, adjust the medium pH value is ignored when the concrete operation,should grasp the TTC mainly solution,too much of the TTC solution wil inhibit the growth of microbial bacteria,therefore, adding the right amount of TTC solution is very necessary for inspection,can ef ectively promote the cosmetics microbial inspection work orderly.
