What is "nonylphenol"

n. (context organic compound English) Any of a family of closely related organic compounds, a subset of the alkylphenols, that are precursors to commercially important detergents.

Nonylphenols are a family of closely related organic compounds called alkylphenols. They are used in manufacturing antioxidants, lubricating oil additives, laundry and dish detergents, emulsifiers, and solubilizers. These compounds are also precursors to the commercially important non-ionic surfactants alkylphenol ethoxylates and nonylphenol ethoxylates, which are used in detergents, paints, pesticides, personal care products, and plastics. Nonylphenol has attracted attention due to its prevalence in the environment and its potential role as an endocrine disruptor and xenoestrogen, due to its ability to act with estrogen-like activity. Nonylphenol has been found to act as an agonist of the GPER (GPR30).
