DEA - Diethanolamine

Is organic substances that function as emulsifiers to produce foam and bubbles in cosmetics. This ingredient can also be used to adjust a product's PH. DEA may cause an allergic reaction in some people, producing a mild form of dermatitis. Large doses, however, are thought to be potentially carcinogenic to humans—especially as it builds up in the system over time. Therefore, California banned its use.
