1,2一己二醇( 1, 2-Hexanediol )。这种多元醇,目前未列人防腐剂,而是定义为保湿剂、渗透助剂。添加量在5%左右,就具有明确的防腐效果。所以,品牌大多拿这样的成分,替代防腐剂,并声称无防腐剂配方。但这一类成分的制菌效果较为消极,对开封后使用期间的是否污染较无法掌握。开封后的防腐环境,与密封时的防腐环境,有非常大的不同。也因此,无防腐剂的产品,保存期限趋向保守。


https://www.truthinaging.com/ingredients/hexanediol-12-hexanediol: According to a patent filed by Proctor and Gamble, Hexanediol and 1,2-hexanediol is a highly effective and mild coupling agent and humectant. It is especially useful when bonding silicone products and can be used at lower concentrations than many other coupling agents, therefore reducing its irritation likeliness.
1,2-hexanediol contains many chemicals in its composition, including: Alpha-Lipoic acids, an antioxidant; Chrysin, a anti-inflammatory bioflavonoid; Diosgenin, a maintainer of healthy blood cholesterol levels; Glucosamine Hydrochloride, which slows joint degeneration; and Indole-3-Carbinol, a nutrient that may prevent cancer (Source).


Pentylene Glycol, 1,2-Hexanediol and Caprylyl Glycol are all soluble in water, with water solubility increasing with decreasing carbon chain length. Although Caprylyl Glycol and Pentylene Glycol have been reported to have some antimicrobial activity, these ingredients may also serve to increase the antimicrobial activity of other preservatives. Pentylene Glycol, 1,2-Hexanediol and Caprylyl Glycol are 1,2-glycol compounds that vary only by the number of carbons. Each of these compounds has a hydroxyl group (-OH) on the first and second carbons. Pentylene Glycol has 5 carbons, 1,2-Hexandiol has 6 carbons and Caprylyl Glycol has 8 carbons in the carbon chain. In cosmetics and personal care products, these ingredients may be used in baby products, bath products, eye makeup, cleansing products, skin care products and hair care products.
