Our factory is dedicated to supplying high - quality
Cosmetics
grade Tween 80, a compound with the CAS number 9005 - 65 - 6.
Product Overview
Tween 80, chemically known as polyoxyethylene (20) sorbitan monooleate, is a non - ionic surfactant and emulsifier. It appears as a viscous, lemon - to - amber - colored oily liquid at 25 °C. Our manufacturing process ensures a minimum purity of 99%, free from impurities, heavy metals, and microbial contaminants.
Key Functions
Powerful Emulsification
: Tween 80 is highly effective in creating and maintaining stable oil - in - water emulsions. In
Cosmetics
formulations, it enables the uniform dispersion of oil - soluble drugs in an aqueous medium. This is crucial for the development of products such as oral suspensions, topical creams, and injectable emulsions, ensuring consistent dosing and improved bioavailability.
Stabilization
: Tween 80 acts as a stabilizer in emulsions and suspensions. It prevents the separation of phases in injectable solutions and vaccines, maintaining the integrity and shelf - life of these liquid medications.
Safety and Compliance
Our
Cosmetics
grade Tween 80 complies with strict international regulations, including those of the US FDA and the European Medicines Agency (EMA). It has a long - established safety profile and is approved for use in a wide range of
Cosmetics
products. Toxicological studies have shown it to have low oral toxicity, making it a reliable choice for drug formulations. Each batch undergoes comprehensive quality control, including tests for pH, viscosity, and microbiological safety.
