What it is
A semi-synthetic surfactant created by reacting coconut oil fatty acids with diethanolamine and acetic acid. It belongs to the cocamide family of mild cleansing agents.
How it works
It reduces the surface tension between water and oil, allowing dirt and excess sebum to be rinsed away. It also stabilizes foam, giving a satisfying lather that many people associate with effective cleansing.
Pros
Gentle on skin
Less stripping than sodium lauryl sulfate, making it suitable for daily use without causing excessive dryness.
Improves product feel
Creates a dense, creamy foam that makes cleansing feel more luxurious and effective.
Cons and cautions
DEA association
As a diethanolamine derivative, it has been scrutinized for potential nitrosamine formation, though levels in cosmetics are tightly regulated.
Not for sulfate-free trends
Some consumers actively avoid DEA ingredients, limiting its appeal in natural or clean beauty lines.
Best for
- People with normal to dry skin who want a mild cleanser
- Anyone looking for a rich, creamy lather in their shampoo or body wash
Use caution if
- Those with known sensitivity to coconut-derived ingredients
- Individuals avoiding all DEA-related compounds due to personal preference
Usage tips
Safety summary
Generally recognized as safe for rinse-off use at typical concentrations. Regulatory bodies have set limits on DEA content to prevent nitrosamine contamination, and most commercial ingredients meet these standards.
Research notes
Studies indicate low acute toxicity and skin irritation potential. Long-term safety focuses on nitrosamine formation, which is controlled by good manufacturing practices and ingredient purity standards.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) within concentration limits. The EU restricts DEA in cosmetics to minimize nitrosamine formation.
- Common uses
- Shampoos, Body washes, Facial cleansers, Liquid soaps
- Environmental note
- Derived from renewable coconut oil and considered readily biodegradable, though the DEA component requires careful manufacturing to avoid impurities.
Good to know
- Di-TEA-Cocamide Diacetate is considered biodegradable and is often used as a replacement for harsher sulfate cleansers.
- The 'TEA' in the name refers to triethanolamine, but this ingredient uses diethanolamine (DEA) — a related compound.
