增塑作用

Alkylphenols are applied widely as the rubber additives surfactants in domestic and industrial products, antioxidants and so on. As it's decomposer, nonylphenol has a steady chemical characteristics and exist widely in environment. As it's molecule structures are similar as 17beta-estradiol in human body, and it can combine with estradiol receptor simulating it, disrupt endocrine system and induce health damage effect. Many studies on environmental endocrine disrupting chemicals approved that NP have weaken estradiol functions.
