Ingredient review
Dihydroxyethyl Cocamine Dioleate
INCI: DIHYDROXYETHYL COCAMINE DIOLEATE
A gentle, coconut-derived cleansing ingredient that helps remove dirt and oil without stripping the skin.
In plain English
Dihydroxyethyl Cocamine Dioleate is a mild cleansing agent made from coconut oil and a fatty acid called oleic acid. It works by helping water mix with oil and dirt so they can be rinsed away easily. Because it's designed to be gentle, it's often used in products for sensitive or dry skin that still need effective cleansing.

What it is
A semi-synthetic surfactant and emulsifier created by reacting coconut-derived amines with oleic acid. It belongs to a class of mild cleansing agents often used in sulfate-free or low-irritation formulas.
How it works
It reduces the surface tension between water and oil, allowing them to blend. This helps lift sebum, makeup, and impurities from the skin so they can be washed away without harsh scrubbing.
Pros
Mild on skin
This ingredient is designed to clean without stripping the skin's natural moisture barrier, making it suitable for daily use.
Coconut-derived
Sourced from renewable coconut oil, it appeals to those seeking plant-based or naturally-derived ingredients in their routine.
Cons and cautions
Potential for mild irritation
While generally gentle, repeated use on very sensitive or compromised skin could lead to slight dryness or irritation.
Less common in formulas
It's not as widely used as other mild surfactants, so you may need to check labels carefully to find products containing it.
Best for
- People with normal to dry skin looking for a mild cleanser
- Those who prefer coconut-derived ingredients over harsher sulfates
Use caution if
- Individuals with known coconut oil or oleic acid allergies
