|What is it?
|Cocamide DEA is a liquid non-ionic liquid surfactant made from coconuts. It helps boost foam, thicken surfactant blends, and condition the hair.
|Pale yellow liquid
|“The CIR Expert Panel concluded that Cocamide DEA was safe as used in rinse-off products and safe at concentrations of less than or equal to 10% in leave-on products.” (source)
|Active surfactant matter
|Varies by product; mine is 85%
|Approximate Melting Point
|Liquid at room temperature
|8.5–11 at 1% (varies by product)
|Why do we use it in formulations?
|Cocamide DEA helps boost the foam in our formulations, thicken surfactant blends, and condition the hair.
|Do you need it?
|Refined or unrefined?
|Cocamide DEA only exists as a refined product.
|Good thickener and foam booster.
|Harder to find, depending on where you live.
|Alternatives & Substitutions
|I’d try a different non-ionic liquid surfactant, like one of the glucosides. This may result in a thinner product, depending on the formulation, so you may have to adjust the formulation to get the desired final viscosity.
|How to Work with It
|Include Cocamide DEA in the surfactant/water phase of your formulations. Cocamide DEA can be hot or cold processed.
|Storage & Shelf Life
|Stored somewhere cool, dark, and dry,
|Tips, Tricks, and Quirks
|Cocamide DEA and Cocamide MEA are not the same.
|Recommended starter amount
|100mL (3.3fl oz)
|Where to Buy it
|Buy it from an online DIY ingredient supplier or Amazon. Mine is from Mystic Moments.
