Steareth-2/21 is a white waxy solid. This product is a pair of non-ionic O/W emulsifiers. Stearyl polyether-2 is oil-soluble, and stearyl polyether-21 is water-soluble. It is added to the oil phase and the water phase respectively to form a stable emulsification system, and the emulsified paste system is delicate and bright. It can form a liquid crystal system with specific grease. Suitable for a wide range of PH values, with excellent lubricity, spreadability, solubility and stability..
STEARETH-2 is an oil-in-water nonionic emulsifier with superior performance used in polar oil creams and emulsions. It can form a more powerful emulsification system and is a versatile and efficient emulsifier. Applicable to a wide range of pH values, with excellent lubricity, spreadability, solubility and carrier properties. Used as an emulsifier to prepare creams and lotions.
