About Styrenated Phenol Ethoxylate 20 mole

Chemical Information

- CAS Number: 9084-06-4 (general)

- HS Code: 34021190 (non-ionic surfactants)

- Molecular Formula: C6H5CH=CHC6H4O(OCH2CH2)nOH (n=5-30)

- Molecular Weight: approx. 440-880 g/mol

Styrenated Phenol Ethoxylate (SPE 20) is a non-ionic surfactant produced by reacting styrenated phenol with approximately 20 moles of ethylene oxide. It is valued for its strong emulsifying, dispersing, and wetting properties in industrial and specialized applications.

Performance Highlights

Highly effective at emulsifying oils, resins, and waxes
Strong dispersing capability for pigments and solid particles
Excellent wetting and cleaning performance
Stable under acidic, alkaline, and high-temperature conditions

Key Applications

Industrial and institutional cleaners for heavy-duty cleaning
Agrochemical formulations as an emulsifier for EC, EW, and SC pesticide systems
Textile and leather processing, including scouring, dyeing, and dispersing aids
Paints, coatings, and inks as a pigment and resin dispersant
Oilfield and metalworking fluids, supporting emulsification, lubrication, and wetting

Environmental & Regulatory Considerations

Styrenated phenol ethoxylates are under increasing scrutiny due to:

Limited biodegradability
Potential formation of toxic phenolic byproducts
Aquatic toxicity concerns

As a result:

Their use is restricted or discouraged in some regions and applications
Many industries are switching to more environmentally friendly alternatives, such as:
- Alcohol ethoxylates
- Alkyl polyglucosides (APGs)
- Sugar-based or EO/PO block surfactants
