COCAMIDE DEA
Commonly Found In
Overview
COCAMIDE DEA is a cosmetic ingredient primarily used for EMULSION STABILISING. It is commonly found in various cosmetic formulations and serves important functions in personal care products.
Also known as: Coconut Diethanolamide, Coconut Oil Amide of DEA, Lauric Diethanolamide
Key Benefits
Cocamide DEA functions as a foam booster and emulsion stabilizer in cleansing formulations. It has no direct skin benefits and has been phased out by many manufacturers due to carcinogenicity concerns from nitrosamine formation.
Skin Compatibility Ratings
Comedogenic Rating
Moderate comedogenic potential; fatty acid alkanolamide with some occlusive properties. Reported as comedogenic in some studies using the rabbit ear model.

Irritancy Rating
Moderate irritancy potential; may cause contact dermatitis in susceptible individuals. Concerns regarding nitrosamine formation (DEA reacts with nitrosating agents) led to restrictions in some markets. CIR re-evaluated safety in 2019.

Strictness Ranking
πΏ Natural Sources
Not found in nature. Derived from coconut oil fatty acids combined with diethanolamine (DEA). The coconut oil component is natural, but the final product is synthetic.
π How It's Made
Produced by reacting coconut oil fatty acids with diethanolamine at elevated temperatures. The reaction produces a mixture of amides that act as foam boosters and thickeners.
π Uses in Cosmetics
Used in cosmetic products primarily for emulsion stabilising, surfactant - cleansing, surfactant - emulsifying, surfactant - foam boosting, viscosity controlling.
π¬ Other Applications
Used in industrial cleaning products, dishwashing detergents, and as an emulsifier in various industrial applications.
π‘ Fun Facts
- β’ Despite being derived from natural coconut oil, cocamide DEA was classified as possibly carcinogenic (Group 2B) by the International Agency for Research on Cancer in 2012
- β’ California added it to its Proposition 65 list of chemicals known to cause cancer, leading many brands to reformulate their products
- β’ It was once one of the most common foam boosters in shampoos before safety concerns led to widespread reformulation

Frequently Asked Questions
Why is COCAMIDE DEA banned in the EU but allowed in the US?
The EU follows a precautionary principle, banning COCAMIDE DEA under III/60 due to potential safety concerns. The US FDA has not found sufficient evidence to prohibit its use, allowing it under different safety assessment standards. This reflects differing regulatory philosophies between the two regions.
Why is COCAMIDE DEA banned in the EU but allowed in Japan?
The EU prohibits COCAMIDE DEA (III/60) based on their strict safety criteria. Japan's Ministry of Health, Labour and Welfare (MHLW) has evaluated the ingredient and permits its use, potentially with different safety data or usage conditions.
What is COCAMIDE DEA used for in cosmetics?
COCAMIDE DEA is primarily used for emulsion stabilising in cosmetic products. It also serves as surfactant - cleansing, surfactant - emulsifying. The ingredient is commonly found in various cosmetic and personal care products.
Which countries regulate COCAMIDE DEA?
COCAMIDE DEA is banned in EU. It has concentration limits or usage restrictions in UK. The ingredient is freely allowed in JP, US.
Are there alternatives to COCAMIDE DEA?
Due to regulatory restrictions on COCAMIDE DEA, cosmetic manufacturers often use alternative ingredients with similar functions. For emulsion stabilising, alternatives may include other approved ingredients in the same category. Consult product labels for specific formulations, and look for products compliant with your region's regulations.
