What it does
Cocamide DEA is used mostly in shampoos, bath products and lotions to increase of stabilize their ability to foam. When used in haircare products, it allows for oil and dirt to be trapped and then rinsed off. In addition, it can also increase and thicken the water part of beauty products.
Cocamide DEA is safe to be used in rinse-off products, while in leave-in ones can only be used in concentrations up to 10%. However, this ingredient can be mildly irritating.
In addition, Cocamide Dea should never be used in formulations that contain nitrosating agents or formaldehyde-releasing preservatives to avoid the formation of nitrosamines, which are carcinogenic.
