液体洗涤剂生产中微生物的控制及防腐剂的评价方法

Control of microbial and evaluation of preservative in producing liquid detergent

通过对液体洗涤剂生产的长期监控,发现水系统的控制和软化水的贮存对产品微生物的控制至关重要。用微生物挑战性实验评价液体洗涤剂的防腐性能是一种较好的方法,pH值对防腐性能也有比较大的影响,因此在评价中应同时考虑产品的pH值,明确产品的pH值控制范围。

We find it is important to control water system and reserve of softˉwater in microbial control of product through our long-term study in producing of liquid detergent.The microbial challenge test is a good method of evaluating preservation effect of liquid detergent preservative.pH is great effect to preservative,so we should consider pH value in evaluation and confirm the pH range of product.
