List of harmful ingredients in soaps, skin care and home care products

This list was made possible thanks to more expert concerned people and associations like ewg.org.

I’m not a chemist but my life greatly improved once I stopped using common products with chemicals bought in supermarkets and even sometimes found in health shops.

The ingredients found below are from a non-exhaustive list. More harmful chemicals exist. Please visit ewg.org website or any other experts to check any ingredient that you want to check.

HARMFUL INGREDIENT NAMESYNONYM NAMESMAY BE CONTAINED INDESCRIPTION
1,4 Dioxane1,4-DIETHYLENE DIOXIDE; 1,4-DIOXACYCLOHEXANE; DI (ETHYLENE OXIDE) ; DIETHYLENE DIOXIDE; DIETHYLENE DIOXIDE (OSHA) ; DIETHYLENE ETHER; DIOKAN; DIOKSAN (POLISH) ; DIOSSANO-1,4 (ITALIAN) ; DIOXAAN-1,4 (DUTCH) ; DIOXANPOLYSORBATE-20, SODIUM LAURETH SULFATE, PEG-100 STEARATE, POLYSORBATE-60 , CETYL PEG/ PPG-10/ 1 DIMETHICONE , CETEARETH-20 , LAURETH-7, PEG-40 HYDROGENATED CASTOR OIL, PEG/ PPG-18/ 18 DIMETHICONE , POLYSORBATE-80 and petroleum-based ingredients1,4 Dioxane is a contaminant found in most cosmetics and products meant for personal care. It has a high hazard rating of 8 in EWG’s Skin Deep Cosmetics Database. It is also listed as a carcinerogen
PetrolatumPetrolatum (mineral oil jelly) is used as a barrier to lock moisture in the skin. A petroleum product, petrolatum can be contaminated with polycyclic aromatic hydrocarbons (PAHs). Studies suggest that exposure to PAHs — including skin contact over extended periods of time — is associated with cancer. i On this basis, the European Union classifies petrolatum a carcinogen ii and restricts its use in cosmetics. PAHs in petrolatum can also cause skin irritation and allergies.
Sodium Lauryl Sulfate (SLS)Sodium Laureth SulfateThis surfactant can be found in more than 90% of personal care and cleaning products. It is known to be irritant to the skin, lung, and eye. SLS is in California’s Proposition 65 List of Carcinogens. It can provoke irritations and allergic reactions
FragrancePerfumeThis term was created to protect a company's secret formula. The word "fragrance" or "parfum" on the product label represents an undisclosed mixture of various scent chemicals and ingredients used as fragrance dispersants such as diethyl phthalate. Fragrance mixes have been associated with allergies, dermatitis, respiratory distress and potential effects on the reproductive system.
