Lauryl Polyethylene (LPE) is a common non-ionic surfactant, which is widely used in the field of chemical raw materials. This article will detail the properties and uses of laureth alcohol polyoxyethylene ether.

1. properties

1. physical properties
lauryl alcohol polyoxyethylene ether is usually colorless to light yellow viscous liquid or solid, with a special smell. Its melting point and boiling point depend on the length of the polyoxyethylene chain. As the chain length increases, the melting point and boiling point gradually increase. Lauryl alcohol polyoxyethylene ether is soluble in water, ethanol, acetone and other organic solvents, but insoluble in mineral oil.
2. chemical properties
lauryl alcohol polyoxyethylene ether has good chemical stability, acid, alkali, salt and oxidant. Under high temperature and acidic conditions, polyoxyethylene lauryl ether is prone to hydrolysis. In addition, it has excellent foamability and emulsifiability.

2. uses

lauryl alcohol polyoxyethylene ether in the field of chemical production raw materials has a wide range of uses, mainly in the following aspects:

1. emulsifier
lauryl alcohol polyoxyethylene ether as emulsifier, can improve the stability of oil-water mixture, prevent oil-water separation. In the field of cosmetics, coatings, inks, etc., lauryl polyoxyethylene ether as an emulsifier can make the product more uniform and stable.
2. Moisturizer
Lauryl alcohol polyoxyethylene ether has the effect of reducing surface tension, can be used as a wetting agent to improve the spread of liquid on the solid surface. In the textile, printing and dyeing industries, lauryl alcohol polyoxyethylene ether as a wetting agent can improve the dye dip performance and fabric feel.
3. Dispersant
lauryl alcohol polyoxyethylene ether can be used as a dispersant to uniformly disperse solid particles in the liquid to prevent particle agglomeration. In the fields of ceramics and pigments, lauryl alcohol polyoxyethylene ether as a dispersant can improve the performance and stability of the product.
4. Cleaning agent
lauryl alcohol polyoxyethylene ether has good decontamination ability and foaming, and can be used as a cleaning agent to remove grease and stains. In the field of washing products, industrial cleaning, etc., lauryl polyoxyethylene ether as a cleaning agent can improve the cleaning effect.

In conclusion, lauryl polyoxyethylene ether, as a common non-ionic surfactant, has a wide range of uses in the field of chemical production raw materials. Because of its excellent emulsification, wettability, dispersibility and cleaning performance, polyoxyethylene lauryl ether has been widely used in various fields.
