Studies have found around 15 chemicals that are positively associated with younger menopausal age and the two major culprits were phthalates found in everyday makeup and personal care products.
Of the 13 chemicals the strongest influence was 3.8 years younger for mono-(2-ethyl-5-hydroxyhexyl)phthalate, compared with less-exposed women.
Another study found a link between early menopause and elevated serum levels of perfluorooctanoic acid (PFOA), or teflon an industrial chemical used in several nonstick and stain-repellant applications. Manufactured for decades, PFOA is now widespread in the biosphere, and most people have some in their bodies. The chemical accumulates in blood, so women of reproductive age will eliminate some of it when they menstruate.
This result was also found in two prior studies of polyfluoroalkyl chemicals (PFCs) including PFOA.
