Product Description
TERGITOL 15-S-9 Surfactant is a biodegradable, clear liquid that is ideally suited for applications requiring outstanding surface-chemical performance from a water soluble product. TERGITOL 15-S-9 Surfactant is a mixture of linear secondary alcohols reacted with ethylene oxide. As a nonionic surfactant, it is chemically stable in the presence of dilute acids, bases, and salts, and it is compatible with anionic, cationic, and other nonionic surfactants. TERGITOL 15-S-9 Surfactant is soluble in water, chlorinated solvents, and most polar organic solvents.
Features and Benefits
The unique “T”-shaped molecular structure of TERGITOL 15-S-9 Surfactant, combined with the very low levels of unethoxylated secondary alcohols and low-mole adducts present, imparts highly desirable end-use features, including:
- Excellent detergency performance
- Outstanding wetting properties
- Excellent rinseability
- Low foam stabilities
- Versatile solubility characteristics
- Low pour point
- Low neat and aqueous viscosities
- Narrow aqueous gel range
- Rapid dissolution rates
- Low odor
