6 Cancer-Causing Toxins You Should Avoid When Buying A Shampoo
Most people have some idea that the chemicals in shampoo and other personal care products are not always completely safe. However, many aren’t aware how common carcinogenic and toxic ingredients are. The FDA doesn’t regulate shampoo and other similar products, and therefore it’s legal to put practically anything in them. Here are 6 ingredients to keep an eye out for.
1. Propylene Glycol
Propylene glycol is a chemical most often used as a humectant, or a skin-moisturizing agent. It’s also used as a viscosity-decreasing agent, or a chemical that makes your personal care products less sticky in texture. However, this ingredient can be highly irritating to your skin, eyes, and lungs. There is some evidence that propylene glycol has toxic and allergenic properties. Even a propylene glycol concentration of just 2% can cause severe skin irritation and even hives. This chemical is classified as toxic according to the Environment Canada Domestic Substance List. Reduce your chances of skin irritation by looking for shampoos, as well as other personal care items, that are free of this ingredient.
2. Sodium Laureth Sulfate
Sodium laureth sulfate, also known as sodium lauryl sulfate, is used as a surfactant, detergent, and emulsifier. This chemical is found in industrial cleaning agents as well as almost every commercially available shampoo, liquid soap, and laundry detergent. The main problem with sodium laureth sulfate is that due to the manufacturing process, it is often contaminated with 1,4 dioxane, a carcinogen. Research shows that sodium laureth sulfate can cause eye and skin irritation, endocrine disruption, ecotoxicity, organ toxicity, developmental toxicity, reproductive toxicity, neurotoxicity, and possible DNA mutations which lead to cancer. Do your body a favor and look for shampoos that don’t contain sodium laureth sulfate.

3. Diethanolamine, or DEA
DEA is a chemical used to adjust the pH of products. However, it is harmful, and in fact has been banned in Canada for use in cosmetics. There is evidence that it irritates the skin, eyes, and lungs, and can cause organ toxicity. There is strong evidence that DEA is a human immune, respiratory, and skin toxicant. According to the California Environmental Protection Agency, DEA is a possible human carcinogen. You should stay on the safe side and avoid shampoos containing this ingredient.
