Diethanolamine (DEA)

Diethanolamine (DEA) is an amino alcohol with the chemical formula NH2CH2CH2OH. It is used as an emulsion stabilizer, foam preventer, and viscosity enhancer in industrial chemicals and personal care products.

DEA is a basic compound and can react with acids to form salts. Therefore, it can be used to adjust the pH balance of personal care products such as shampoos and soaps.

However, excessive use and prolonged exposure to DEA can cause skin irritation and allergic reactions in some people. Additionally, some studies suggest that DEA may be carcinogenic.

Therefore, it is important to seek dermatologist advice and read product labels before using products containing DEA, especially for people with sensitive skin. DEA is banned or restricted in some countries.
