1,2-Hexanediol , a polyol, is not currently listed as a preservative, but is defined as a humectant, penetration aid. Usually the addition amount is about 5%, it will have a clear anti-corrosion effect. Therefore, brands mostly take such ingredients, substitute preservatives, and claim to be preservative-free formulas. However, the antibacterial effect of this type of ingredients is relatively negative, and it is difficult to grasp whether there is contamination during use after opening. However, for the preservation of the product after opening, its antibacterial effect cannot be compared with that of real preservatives. Since the anti-corrosion environment after opening is very different from the anti-corrosion environment during sealing, the shelf life of preservative-free products also tends to be conservative.
