A key ingredient behind rich, stable lather in cleansing formulas
Cocamide DEA is a viscous, paste-like additive derived from coconut oil that plays a major role in the manufacturing of shampoos, shower gels, liquid soaps, and countless other cleansing products across the world. It belongs to the broader category of Surfactants, and its primary function is to thicken formulas and stabilize foam, giving finished products a pleasant body without relying heavily on salt or separate thickening agents. Across global personal care manufacturing, this ingredient remains a go-to thickener thanks to its affordability and consistent performance in both sulfate and sulfate-free bases.
The main application of cocamide DEA lies in industrial and semi-industrial production of body and hair cleansers: shampoos, bubble baths, intimate hygiene washes, dish soaps, and household detergents. It is typically added during the blending stage of the primary surfactants, at a temperature range of 40 to 60 degrees Celsius, allowing it to dissolve evenly into the water phase without clumping. Recommended usage levels in finished formulas range from 1 to 5 percent of the total batch weight, and exceeding the upper limit can result in excessive viscosity that complicates filling lines on an industrial conveyor. The raw material should be stored in a tightly sealed container, in a dry space at room temperature, away from direct sunlight and temperature fluctuations that could affect its texture.
Cocamide DEA pairs exceptionally well with other anionic and amphoteric surfactants, boosting their performance and producing denser, more stable foam. It is frequently combined with milder sugar-based surfactants such as Surfactant GlucoTain Plus 50 ml to achieve a balanced formula with a pleasant feel and reduced irritation potential. For added mildness and a light natural scent, some formulators turn to plant-based surfactants like RESSASOL Mango 25 ml, which is especially valued in formulas aimed at sensitive skin. Cocamide DEA also works well alongside its closest relative, Cocamide MEA 100 g, and combining the two allows precise fine-tuning of thickness and foam stability depending on formula requirements.
The 100 ml packaging suits home formulators and small cosmetic labs experimenting with new recipes before scaling up to larger production runs. This size makes it easy to calculate exact ratios and run several trial batches without risking a large volume of raw material. When working with small quantities, precise weighing is essential, since even a slight deviation from the recommended dosage noticeably affects the final texture of the product.
Coconut foam bath wash
Distilled water 210 ml
Cocamidopropyl betaine 55 ml
Cocamide DEA 14 ml
Vegetable glycerin 8 ml
Coconut fragrance oil 3 ml
Broad-spectrum preservative 5 ml
Combine
the water and cocamidopropyl betaine in a heatproof container and warm the
mixture on a water bath to around 45 degrees Celsius, then add the cocamide DEA
and stir gently until fully dissolved without forming bubbles. Remove from the
heat, blend in the glycerin, preservative, and fragrance oil until smooth, then
allow the mixture to cool to room temperature before transferring the finished
wash into a clean pump bottle.
