1 2-hexanediol preservative

1, 2-hexanediol (1, 2-hexanediol) is a polyol that is not currently listed as a preservative, but is defined as a moisturizer and osmotic aid. Usually the amount added is about 5%, it will have a clear anti-corrosion effect. Therefore, brands mostly take such ingredients, replace preservatives, and claim to be preservative-free formulations. However, the antibacterial effect of this kind of ingredients is more negative, and whether the pollution during the use of the opening is more difficult to grasp. However, for the preservation of the product after opening, its antibacterial effect can not be compared with real preservatives. Because the anti-corrosion environment after opening is very different from the anti-corrosion environment when sealing, the storage life of preservative-free products also tends to be conservative.
