Chemicals in young girls dropped dramatically in a 3 day trial 

  According to  UC Berkeley and Clinica de Salud del Valle de Salinas a new study revealed, Teenage girls who switched cosmetics for just three days had a big drop in certain chemicals in their bodies. 

The team looked at four chemicals used in cosmetics, shampoos and lotions. These chemicals, known as “hormone disruptors,” can interfere with estrogen and testosterone in the human body. The four chemicals were:

phthalates — found in nail polish and fragrance

parabens — a preservative used in cosmetics

triclosan — an antibacterial agent

oxybenzone — a sunscreen agent

In the study, 100 Latina girls in the Salinas area swapped their cosmetics and other personal care products for new ones that did not include the four chemicals on their labels. Researchers took urine samples before and after the three-day test.

Overall, the girls showed a 25-45 percent drop in the levels of the four chemicals.

Reducing Exposure

Lead author Kim Harley, associate director of UC Berkeley’s Center for Environmental Research and Children’s Health, said this type of approach had never been studied before.
“We hoped that if we changed to lower-chemical products, we would see significant reductions,” Harley said. “So that was positive for us, that we found that you really could reduce your exposure to these chemicals through these changes.”
The study was published in the journal Environmental Health Perspectives.

Harley said there’s “a lot we don’t know yet” about the effects of these chemicals in the human body, but some human research shows “they are associated with neurodevelopment problems in children, respiratory problems like asthma in children and obesity problems.”
The reason the study was done on teenage girls is because they tend to use more personal care products than adult women and because adolescence may be a time of particular risk.
