About Styrenated Phenol Ethoxylate SPE 20

Styrenated Phenol Ethoxylate (SPE 20) is a nonionic surfactant synthesized by the ethoxylation of styrenated phenol with approximately 20 moles of ethylene oxide.

Performance Benefits

Excellent emulsifying power for oils, resins, and waxes
Strong dispersing capability for pigments and solids
Effective wetting and detergency
High stability under acidic, alkaline, and high-temperature conditions

Typical Applications

Industrial and institutional cleaners
Agrochemical formulations
Emulsifier for EC, EW, and SC pesticide systems
Textile and leather processing
Scouring, dyeing, and dispersing aids
Paints, coatings, and inks
Pigment and resin dispersants
Oilfield chemicals
Demulsifiers and wetting agents
Metalworking fluids
Emulsification and lubrication support

Environmental & Regulatory Considerations

Styrenated phenol ethoxylates face increasing scrutiny due to:

Poor biodegradability
Potential formation of toxic phenolic degradation products
Aquatic toxicity concerns

Consequently, SPEs are:

Restricted or discouraged in certain regions and applications
Often substituted with more sustainable alternatives, such as:
- Alcohol ethoxylates
- Alkyl polyglucosides (APGs)
- Sugar-based surfactants or EO/PO block surfactants
