Level of Chemicals in body drops on using Chemical free Cosmetics

A study was conducted to see change in level of hormone-disrupting chemicals in the body with respect to use of cosmetics, which have varied chemicals. It was concluded that the level chemicals dropped dramatically. The experiment was conducted on Latin teenagers as a part of the Health and Environmental Research on Makeup of Salinas Adolescents (HERMOSA) study. The results were published on March 7 in the journal Environmental Health Perspectives.

The researchers from the University of California, Berkeley, and Clinica de Salud del Valle de Salinas showed that how avoiding daily used cosmetics such as makeup, shampoos and lotions have ability to reduce level of chemicals in the hormones. The HERMOSA is collaborated effort between both universities to encourage young people to participate in activities of public health and the environment.

In order to conduct experiment, teen participants were provided with chemical free personal care products. They didn’t have chemicals such as phthalates, parabens, triclosan and oxybenzone, which are generally found in products like cosmetics, fragrance, hair products, soaps and sunscreens. These chemical interrupts endocrine system in bodies of animal, as shown in several animal studies.

The urine samples of participants taken before and after three days into experiment of using lower- chemical products were analyzed. The participants had dropped level of the chemicals in their body, as observed through urine samples. Highest level of fall was seen in propyl parabens, while next highest was in Methyl. Both are used as preservatives in cosmetics, the percentage fall for former was 45% while for latter it was 44%.

Metabolites of diethyl phthalate, which is commonly used in fragrances, fell by 27% by the end of the trial. There was 36% of decline seen in both triclosan and benzophenone-3. Triclosan is found in antibacterial soaps and some brands of toothpaste; whereas benzophenone-3 (BP-3) is found in some sunscreens under the name oxybenzone.

“One of the goals of our study was to create awareness among the participants of the chemicals found in everyday products, to help make people more conscious about what they’re using. Seeing the drop in chemical levels after just three days shows that simple actions can be taken, such as choosing products with fewer chemicals, and make a difference,” said Maritza Cárdenas, the study co-author.
