The study identified consumer products containing carcinogens and reproductive and developmental toxicants that are widely used at home and in the workplace. Consumers have limited information about these products’ ingredients.
Making a dangerous situation even worse, consumers are likely co-exposed to many hazardous chemicals together as mixtures through use of many different products, which often contain many chemicals of health concern.
Similarly, people experience aggregate exposures to the same chemical from multiple sources. Methanol, which is listed under Prop 65 for developmental toxicity, was found in 58 product categories. Diethanolamine, a chemical frequently used in products like shampoos that are creamy or foamy, appeared in 40 different product categories. Both Canada and the European Union prohibit its use in cosmetics because it can react with other ingredients to form chemicals that may cause cancer.
Some chemicals, such as N-methyl-2-pyrrolidone and ethylene gylcol, are listed under Prop 65 because they are reproductive or developmental toxicants. Yet they appeared widely in goods such as personal care products, cleansers and art supplies that are routinely used by children or people who are pregnant.Cancer-Causing Chemicals in Shampoo, Lotion, Cleaning Products: Study – Chemical Free Life
