Mothers who use during pregnancy cosmetics can cause to their children even before birth unintentionally large amount of damage. A study from California found out, many often the substances contained therein have a strong influence on the hormonal development of children.
Substances in body care products that women use during pregnancy, can affect a study found that the onset of Puberty of their children. A long-term study found such a connection in particular between the substances diethyl phthalate, and Triclosan, and several months earlier the Onset of puberty in girls. The group reported to Kim Harley of the University of California, Berkeley, in the journal "Human Reproduction".
Psyche and cancer: Early puberty increases health risks
"This is important, because we know that puberty in girls, since a few decades earlier and earlier beginnt", is quoted the Epidemiologist, in a communication to the magazine. An earlier Onset of puberty increase in girls is not only the vulnerability to mental health problems, but also the long-term risk for breast and ovarian cancer, emphasizing Harley, with reference to previous studies.
The current results are based on a study started in 1999, and the consequences of pesticides for Pregnant women and their offspring were examined, especially to work in agriculture. In addition, the researchers examined the long-term effect of phthalates, parabens and phenols. These are suspected to influence the hormonal system especially of women.
Overall, the researchers of every pregnant woman, took samples of two urine. Of the 338 children was analyzed at the age of nine years, a urine sample. In the following four years, the researchers looked at all children with a standard test on the Onset of puberty.
In what products the substances of concern?
The results Included the mothers a lot of mono-ethyl phthalate, a Precursor of diethyl phthalate, which acts as a carrier Fragrance or hair softeners, began to write to the pubic hair development of their daughters, about six months earlier, as the researchers. A high concentration of Triclosan in the urine of the mother was associated, therefore, with less than five months earlier the first Menstruation. Triclosan may be included in toothpastes, Deodorants, Soaps and other cosmetics.
Specifically, the substance is approximately in the toothpaste "Colgate Total" as well as in the "Sensitive Extra Toothpaste Trio" of Signal. Similarly, in the shaving cream from Avéne and in the "CK Free Deodorant Stick" from Calvin Klein, as well as in many other cosmetic products. The platform " reported;Codecheck", the data of independent experts convened by, among others, Greenpeace, BUND, WWF and the consumer Initiative.

The influence of the age of puberty
Relationships, the scientists also found between the exposure of children and the Onset of puberty: Thus, high concentrations of Methylparaben, which is used how many more parabens preservative in various cosmetics, in the urine of the girl glands with an earlier development of the chest and an early first Menstruation. The same was true for propyl paraben and the development of pubic hair.
At high values of these substances, the developments began about four to seven months earlier. In boys, the researchers found a significant connection only for Propylparaben: A high concentration of the substance was associated with an earlier maturation of the sex organs.
Substances are contained in many products – and act in low concentrations
The President of the German society for endocrinology, Josef Köhrle, sees in the study a confirmation of previous findings from experiments on mice and rats. "Note the warnings on the possible role of individual substances in low concentrations, in influencing the Pubertät" are;, the physicians at the Charité hospital in Berlin says. As a rule, several substances are caused together in mixtures such effects.
It is also important to note that the surveyed mothers came from low-income strata of the population and therefore hardly on better body care products were able to Dodge, containing less additives. Generally speaking, Köhrle also wants more public attention for substances that do not affect sex hormones, but thyroid and stress hormones or fat metabolism interact.
The phenols scoring Triclosan as well as parabens are used in cosmetics and personal care products as a means to prevent microorganisms and as a preservative. Diethyl phthalate is fixed, however, fragrances.
