The study concluded that the chemical "diethyl phthalate" Which are used in perfumes and cosmetics are responsible for the precocious puberty in girls.
The study also suggests that girls' precocious puberty may occur due to exposure to "methyl paraben", A chemical found in high quality body care products and hand creams.
Researchers from the University of California followed nearly 200 girls from birth to adolescence and searched for signs of puberty every nine months between 9 and 13 years..
Chemicals exposed to girls are thought to affect estrogen, a bad hormone that stimulates early adolescence..
The results showed that girls who had started in adulthood were those whose mothers had been exposed to triclosan, present in some handwashing liquids, antibacterial toothpaste..
The daughters of these mothers registered puberty four months ago on average, and the daughters of mothers with the highest puberty rates "diethyl phthalates", 6 months before the average age of puberty, compared to those whose mothers had lower levels of these chemicals.
The study also revealed links between the chemical and "propyl paraben", Which are used in perfumes, chemicals containing chlorine, which are used in many cosmetics and personal care.
These findings are important to the extent that those who are young are more likely to develop bad cancer and ovarian cancer.
