| Polyoxyethylene lauryl r Usage And Synthesis |
| Description |
As a non-ionic surfactant, polyoxyethylene lauryl r has excellent washing, emulsifying, dispersing, wetting, and solubilizing functions. It also shows strong foaming ability, easy rinsing performance, and excellent detergency. Because this substance acts as one of the lowest irritant species among various surfactants, it is often selected as raw material for mild detergents, shampoos (such as baby shampoos), bath lotion, cleansing milk, and cosmetics. In addition, this chemical may function as emulsifier, softener, wetting agent, and foaming agent. In terms of solubilizing function, this product has been demonstrated to assist in solubilization of hormones, benzoic acid derivatives, and barbiturates.1-3 Besides, when used as surfactant emulsifier, polyoxyethylene lauryl r is proved to be an active agent for preparing nanoemulsions for food applications.4 |
