- antibacterials
Where: Antibacterials (e.g., Triclosan) are found in many products, such as hand soaps, deodorants, toothpastes and body washes.Health Hazards: Some antibacterials are absorbed through the skin. These chemicals may be toxic or carcinogenic. Some antibacterials are secreted in breast milk. One study has found these chemicals may interfere with the functioning of testosterone in cells. Antibacterials can kill the 'good' protective bacteria as well as pathogens, actually increasing susceptibility to infection. The products may increase the rate of development of resistant strains of bacteria.
- butyl acetate
Where: Butyl acetate is found in nail strengtheners and nail polishes.Health Hazards: Butyl acetate vapors may cause dizziness or drowsiness. Continued use of a product containing butyl acetate may cause skin to crack and become dry.
- butylated hydroxytoluene

- coal tar
Where: Coal tar is used to control itching and scaling, to soften skin, and as a colorant.Health Hazards: Coal tar is a human carcinogen.
- diethanolamine (DEA)
Where: Diethanolamine is a contaminant associated with cocamide DEA and lauramide DEA, which are used as emulsifiers and foaming agents in products such as shampoos, shaving creams, moisturizers, and baby washes.Health Hazards: DEA can be absorbed into the body through the skin. It can act as a carcinogen and can be converted to nitrosamine, which is also carcinogenic. DEA is a hormone disruptor and robs the body of choline needed for brain development.
