Butylparaben can have several endocrine disrupting effects

Research suggests that butylparaben – which is used in cosmetics and skin care products such as sunscreen – have more endocrine disrupting effects than previously thought. Researchers have observed endocrine disrupting effects on the development of the reproductive system in rats that are exposed to the compound prenatally. The researchers have found reduced sperm quality as well as changes in the prostate, testicles, ovaries and breast development.
