Product Description

Tween emulsifiers, a series of nonionic surfactants, belong to the polysorbate family and are widely recognized for their exceptional emulsifying, dispersing, and stabilizing properties. These synthetic compounds are derived from sorbitol and fatty acids, forming hydrophilic polyoxyethylene chains and hydrophobic fatty acid tails. Common variants include Tween 20 (polyoxyethylene sorbitan monolaurate), Tween 40 (palmitate), Tween 60 (stearate), and Tween 80 (oleate), each tailored for specific applications based on their Hydrophilic-Lipophilic Balance (HLB) values, which range from 8 to 16.5.

Key Features:
High Emulsification Efficiency: Stabilizes oil-in-water (O/W) emulsions by reducing interfacial tension.
Thermal & pH Stability: Performs effectively across broad temperature ranges and pH conditions.
Water Solubility: Highly soluble in aqueous systems, enhancing compatibility with hydrophilic formulations.
Low Toxicity: Generally recognized as safe (GRAS) for use in food, pharmaceuticals, and cosmetics.
Biocompatibility: Suitable for biomedical and pharmaceutical formulations.
