Studies have shown early puberty in girls with chemicals in personal care products
A new American study has reviewed the link between certain chemicals in personal care products and early puberty in girls. No important link was found in the boys. Although there are certain limitations, research contributes to a growing literature that suggests that exposure to certain chemicals that endocrine disorders can affect puberty in children.

The study – conducted by Kim Harley and Brenda Eskenazi, of the University of California, Berkeley, and published in the journal Human Reproduction, found that the association between some phthalates, parabens and phenols and early puberty in girls.
Starting with the observation that girls are experiencing puberty at a younger age, lead researcher Professor Harley and her team analyzed data from 339 mothers and their offspring from birth to adolescence.
The researchers measured concentrations of various chemicals in the urine collected from mothers (selectively) during pregnancy and from children at the age of nine. Three types of substances were targeted: phthalate metabolites, paraben and phenols.
Research has shown that girls exposed to these compounds are more likely to experience puberty earlier and this risk is particularly high for mothers daughters exposed to MEP monoethyl phthalate concentrations and triclosan (TCS) and 2,4-dichlorophenol (2,4-DCP) concentrations.
The researchers found that higher levels of MEP and triclosan in the prenatal urine were associated with a change in the developmental time of the child. The higher the concentration, the early signs of puberty appear. A problematic situation in which the difference in exposure, among women in the study, may vary from 1 to 20 depending on the substance.
The researchers also warned that “findings with peripubertal exposure to methyl and propyl parabens could reflect reverse causality if, for example, girls and boys who entered puberty early were more likely to use personal care products containing these preservatives compared to children entering puberty later.”
So be careful in using all kinds of body care products to protect your kids health.
