overview | lauryl alcohol polyether has defoaming properties. Polyether defoamer is a major variety of defoamers at present. It has the advantages of non-toxic, odorless, non-irritating, hard water and acid-base resistance, and good compatibility with the system. Compared with another type of silicon-containing defoamer, although its defoaming performance is not high, its defoaming performance is quite excellent. |
preparation | put catalyst KOH 1 g and initiator decanediol 24 .8g into a reaction kettle, heat to 85 ℃ at room temperature, then vacuum and fill nitrogen for 2-3 times to remove oxygen and water in the reaction kettle, and then heat up to 120-130 ℃, the reaction monomers ethylene oxide (EO), propylene oxide (PO) or their mixtures are added according to the structure of the product. After the reaction is completed, the product is neutralized and filtered with 98% concentrated H2SO4 to obtain lauryl alcohol polyether. |
application | lauryl alcohol polyether has defoaming properties. Lauryl alcohol polyether can be used as an antistatic agent and emulsifier in cosmetics. It should be noted that there is a higher possibility of causing skin allergies and acne. |
