EWG Risk Score:
What is it?
Cocamide DEA is a foaming/detergent agent.
Why is it a risk?
- Nitrosamine and 1,4-dioxane contamination
Cocamide DEA is created by reacting coconut fatty acids with a chemical called diethanolamine. Diethanolamine is created is made by reacting ethylene oxide and ammonia. Ethylene oxide is a known carcinogen and traces of it, along with its carcinogenic by-product 1,4-dioxane can remain in the product. Because it is an amide, it also has the potential for being contaminated with or forming a class of carcinogenic chemicals called nitrosamines.
- Diethanolamide contaminaion
Can contain free diethanolamide either from original processing or as a by-product that releases over time. DEA is a suspected blood toxin, liver toxin, kidney toxin, and neurotoxin. (Source) (Source)
- Can be a contact allergen
Uncommon, but it can be a contact allergen in some individuals. (Source)
- Skin issues
Animal studies showed "incidences of epidermal and sebaceous gland hyperplasia, hyperkeratosis, chronic inflammation, and parakeratosis at the site of application." (Source)
