Performance Characteristics
Tween 60 is an oil-in-water (O/W) emulsifier with excellent emulsifying, dispersing, solubilizing, and stabilizing properties. Its moderate HLB value (14.5) balances hydrophilicity and lipophilicity, making it effective for stabilizing water-based formulations and enhancing the dispersion of oil-soluble ingredients in aqueous systems. It maintains stability across a range of temperatures, ensuring consistent performance in various processing and storage conditions.
Main Uses
- Food Industry: Used as an emulsifier and stabilizer in ice cream, bread, cakes, and other foods. It improves texture and stability—for example, preventing oil-water separation in ice cream and retaining moisture in bread to extend freshness.
- Pharmaceutical Field: Functions as an emulsifier, dispersant, and solubilizer in oral liquids, creams, and other formulations, helping active pharmaceutical ingredients disperse uniformly for enhanced efficacy.
- Cosmetics Industry: Acts as an emulsifier and emollient in creams, lotions, and skincare products, contributing to a smooth, 细腻 texture and improving ingredient compatibility.
- Other Fields: Applied as an antistatic agent and fiber lubricant in the textile industry; used in food machinery cleaning fluids and metalworking fluids to provide wetting, dissolving, and dispersing effects.
Packaging and Storage
- Packaging: Typically packed in 200kg iron drums or 25kg plastic buckets. Custom packaging options are available upon request.
- Storage: Store in a cool, dry place with sealed containers. Protect from direct sunlight and moisture. Shelf life is generally 2 years under proper storage conditions.
