| Polyoxyethylene lauryl ether Usage And Synthesis |
| Description | As a non-ionic surfactant, polyoxyethylene lauryl ether 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 steroid hormones, benzoic acid derivatives, and barbiturates.1-3 Besides, when used as surfactant emulsifier, polyoxyethylene lauryl ether is proved to be an active agent for preparing nanoemulsions for food applications.4

L23 also referred to as Brij 35 or Polyoxyethylene (23) lauryl ether is a non-ionic detergent that lowers the non-specific protein adsorption and reduces electroosmotic pumping drastically. This allows the pH to be varied without adversely affecting the flow rate. It also used as a nonionic surfactant that decreases the absorbance of the blank, inhibits turbidity as well as provides linearity. |
