Parabens

Before starting all of this I had no idea that not only would I be label reading with food, but that I would also be convicted to label read personal care and cleaning products.  I decided that I wanted to faze out use of those things that contained animals products, but what I came to find out that there were other reasons to know what was in stuff.   I was stupid to assume that anything you put on your body had to be non-toxic.  I am now learning what's in some of these products and as I discover these things I want to share them with you.  I figured Parabens were a good place to start since there are a lot of personal care products I've seen that are labeled "Paraben Free".  According to the "Campaign for Safe Cosmetics"......

"Parabens are used to prevent the growth of microbes in cosmetic products and can be absorbed through the skin, blood and digestive system. They have been found in biopsies from breast tumors at concentrations similar to those found in consumer products. Parabens are found in nearly all urine samples from U.S. adults of a variety of ethnic, socioeconomic and geographic backgrounds.


Products That May Contain Parabens


Parabens are several distinct chemicals with similar a molecular structure. Four of these occur frequently in cosmetics: ethylparaben, butylparaben, methylparaben and propylparaben. Methylparaben and propylparaben are the most common of these, each appearing in well over 10,000 of the 25,000 products in the Environmental Working Group's Skin Deep database.

Parabens appear mostly in personal care products that contain significant amounts of water, such as shampoos, conditioners, lotions and facial and shower cleansers and scrubs. While concentration limits are recommended for each paraben, these recommendations do not account for the use of multiple parabens in a single product or for exposure to parabens from several products by a single individual.


Health Concerns

EWG's Skin Deep database, which compares cosmetic ingredients to over 50 international toxicity databases, indicates that parabens are linked to cancer, endocrine disruption, reproductive toxicity, immunotoxicity, neurotoxicity and skin irritation. Since parabens are used to kill bacteria in water-based solutions, they inherently have some toxicity to cells.

A 2004 UK study detected traces of five parabens in the breast cancer tumors of 19 out of 20 women studied. This small study does not prove a causal relationship between parabens and breast cancer, but it is important because it detected the presence of intact parabens – unaltered by the body’s metabolism – which is an indication of the chemicals' ability to penetrate skin and remain in breast tissue.

Of greatest concern is that parabens are known to disrupt hormone function, an effect that is linked to increased risk of breast cancer and reproductive toxicity. Parabens mimic estrogen by binding to estrogen receptors on cells. They also increase the expression of genes usually regulated by estradiol (a form of estrogen); these genes cause human breast tumor cells to grow and multiply in cellular studies.

Cosmetic manufacturers, particularly those in the natural/organic sector, are seeking effective alternatives to prevent microbial growth in personal care products. Another solution is to sell products with a shorter shelf life. Companies are testing new product formulations and have created preservative-free products with a shelf life of six months to one full year. For the products most people use daily – their favorite lotion, face wash or shampoo – products are likely to be used up before they would expire."
