Colonial STDES combines the rapid wetting action of branched-chain alkyl sulfates with the high foam and excellent foam stability of straight-chain ethoxylates. For both industrial and consumer products, this mild surfactant performs as an emulsifier, wetting agent, and detergent base for hard-surface cleaners.
Colonial STDES functions effectively as the sole emulsifier in the emulsion polymerization of styrene, styrene-acrylic, and styrene-butadiene systems. In such polymers, it provides the following properties:
- Emulsion polymers with particle sizes in the 0.05-0.15 micron range
- Lower latex viscosity than can be achieved with fatty alcohol sulfate emulsifiers
- Low foam at low concentrations, compared to most surfactants
- Stability during the polymerization cycle over a wide range of conditions
