| HEALTH CONCERNS |
| Is this chemical a carcinogen? |
No, however, please see controversial issues below. |
| How can it affect me? |
Poly (ethylene glycol) (PEG) is essentially a non-irritant to the skin. Since it does not easily penetrate the skin, and is water soluble, it is easily removed from the skin and therefore, considered safe for use by itself. |
| Are there controversial issues? |
PEG’s are considered ethoxylated surfactants which are capable of becoming contaminated with 1,4-dioxane, which produced liver cancer in rodents in National Cancer Institute (NCI) studies. PEG’s give off a chemical called ethylene oxide, which has also been linked to cancer of the esophagus, stomach, pancreas bladder, as well as affecting the brain and central nervous system.
PEG’s are a potentially carcinogenic petroleum ingredient that can alter and reduce the skin’s natural moisture factor. This could increase the appearance of aging and leave you more vulnerable to bacteria. |
