Wholesales Cosmetic Grade PEG-10 STEARATE 9004-99-3 High Purity Emulsifier Polyoxyethylene Stearate Powder

Polyoxyethylene Stearate 

What is Polyoxyethylene Stearate ?   

Polyoxyethylene Stearate is a nonionic surfactant prepared by esterification of hydrophilic polyethylene glycol chains with hydrophobic stearic acid. This molecule possesses both a hydrophilic head and a hydrophobic tail, allowing it to orient itself at the oil-water interface. Depending on the length of the polyethylene glycol chain, a series of products with varying HLB values ​​can be formed, and these products are widely used in the cosmetics, pharmaceutical, and food industries as emulsifiers, thickeners, and stabilizers.

Feature

Highly Effective Emulsifying and Stabilizing Effect: Polyethylene glycol monostearate significantly reduces oil-water interfacial tension, preventing droplet aggregation by forming a tight interfacial film. Its hydrophobic end connects to the oil phase, while its hydrophilic end connects to the aqueous phase, allowing for the preparation of highly stable O/W emulsion systems with broad compatibility, exhibiting good compatibility with most ionic and nonionic ingredients.

Thickening and Texture-Regulating Effect:At specific concentrations, this ingredient can form micellar structures in the aqueous phase, significantly increasing the system viscosity. Simultaneously, by regulating crystallization behavior, it imparts a delicate, glossy appearance to creams and lotions. Its unique rheological properties also provide a lightweight, non-greasy feel, greatly enhancing the product's texture.

Moisturizing and Barrier-Protecting Effect:Stearic acid segments form a breathable protective film on the skin surface, effectively reducing moisture evaporation. Simultaneously, it enhances the skin barrier function by filling gaps in the stratum corneum. Its moderate lubricity improves product spreadability without creating a greasy feeling, achieving long-lasting hydration.

Applications

In skincare lotions and creams, it is widely used as a core emulsifier in O/W emulsion systems such as creams, lotions, and sunscreens. Its superior emulsifying ability ensures the product remains uniform and stable during storage and use, while its unique thickening properties help achieve the desired viscosity and texture.

In personal care products, it is used as a co-surfactant in cleansers, shower gels, and other cleansing products. Its gentle cleansing power and rich foaming properties enhance the user experience, while effectively reducing skin irritation and tightness caused by other surfactants, making it suitable for formulas for sensitive skin.

Specialty Applications: In makeup products, it acts as a pigment dispersant and texture modifier, helping to achieve even color development and smooth application. In hair care products, it acts as a conditioning agent, effectively improving hair combability and forming a protective film on the hair surface. It can also be used to develop microcapsule formulations with specific functions.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
