description Product Description
Polyoxyethylene (2) stearyl ether is widely used as a nonionic surfactant in various industries due to its emulsifying, dispersing, and wetting properties. In the cosmetics and personal care sector, it is commonly found in creams, lotions, and hair care products, where it helps to stabilize formulations and improve texture. It is also utilized in household and industrial cleaning products to enhance the removal of dirt and grease. Additionally, it serves as an emulsifier in agricultural formulations, aiding in the even distribution of pesticides and herbicides. Its mild nature and compatibility with other ingredients make it a versatile component in many applications.
