What is Nonylphenol?
Nonylphenol (CAS 84852-15-3), also referred to commercially as branched 4-nonylphenol, is a nonionic surfactant intermediate.
Where is Nonylphenol used?
- Industrial and institutional cleaning: improves soil release and surface wetting on hard surfaces and equipment
- Textile and leather processing: scouring agent for uniform dye penetration and surface preparation
- Plastics and rubber compounding: processing aid and antioxidant precursor in stabilizer systems for PVC and rubber
- Paper manufacturing: sizing and coating processes requiring controlled surface tension
- It also acts directly as an emulsifier, dispersant, and wetting agent.
Good to know: Handled according to standard industrial protocols rather than food or pharmaceutical standards such as FCC, USP, Ph. Eur., BP, EP, or ACS.
Commercial specifications
- Purity levels commonly around 99%, conforming to industrial-use specifications
- Bulk quantities via IBC, drum, or tanker
