Uses and Applications of PEG 400 Oleate

1. Emulsifier in Cosmetic Products

PEG 400 Oleate is widely used as an emulsifier in lotions, creams, and ointments. It stabilizes oil and water-based ingredients, providing a smooth, silky texture. Its emulsion-stabilizing properties also enhance the absorption of active ingredients, making it an essential component in cosmetic formulations.

2. Surfactant in Industrial Cleaners

As a powerful non-ionic surfactant, PEG 400 Oleate is a key ingredient in industrial cleaning products. It offers excellent emulsifying and dispersing properties, enabling it to break down and remove oils, grease, and dirt effectively.

3. Solubilizer in Pharmaceuticals

In the pharmaceutical industry, PEG 400 Oleate is used as a solubilizer for lipophilic (oil-based) drugs. This helps improve drug bioavailability and absorption, particularly in topical and oral pharmaceutical products.

4. Lubricant and Plasticizer in Plastics

PEG 400 Oleate is used as a lubricant and plasticizer in the production of plastics and rubber. It enhances flexibility and workability during manufacturing processes, while also improving the final product's quality.

5. Water Treatment Additive

Due to its biodegradable and non-toxic nature, PEG 400 Oleate is employed as an additive in water treatment processes. It enhances the cleaning and emulsifying performance of water treatment chemicals, making it a valuable component in this sector.
