Ingredient review
Olivamide DEA
INCI: Olivamide DEA
A gentle, olive-derived surfactant that helps create rich lather and thicker formulas, but may not suit those avoiding all amide-based ingredients.
In plain English
Olivamide DEA is a cleansing ingredient made from olive oil. It helps shampoos and body washes foam up nicely and feel thicker on your skin. Think of it as a helper that makes your cleanser feel luxurious without being harsh. It's considered mild, so it's often used in gentler formulas, but it's not completely natural since it's chemically modified.

Quick decision guide
Useful, but context matters
Olivamide DEA is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Olivamide DEA.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant created by reacting olive oil fatty acids with diethanolamine (DEA). It appears as a clear to light yellow liquid and is used to improve foam quality and product thickness.
How it works
It lowers the surface tension between water and oil, allowing dirt and oil to be rinsed away. It also stabilizes foam bubbles, giving a richer lather, and increases the viscosity (thickness) of liquid cleansers.
Pros
Gentle foaming
Provides a creamy, stable lather without the harshness of sulfates, making it suitable for daily use on skin and hair.
Improves texture
Helps thicken liquid cleansers, giving them a more luxurious feel that many users prefer in body washes and shampoos.
Cons and cautions
DEA concerns
While olivamide DEA itself is considered safe, some consumers worry about potential impurities from the DEA component, especially in products with other nitrosamine-forming ingredients.
Not natural
Despite being derived from olive oil, it undergoes chemical processing, so it won't appeal to those seeking fully natural or organic formulations.
Best for
- People who enjoy a rich, creamy lather in their cleansers
- Those with normal to combination skin looking for a gentle surfactant
Use caution if
- Individuals with known sensitivity to DEA compounds
- Those seeking 100% natural or organic ingredient lists
Usage tips
Safety summary
Olivamide DEA is considered safe for use in rinse-off cosmetics at typical concentrations. Regulatory bodies have not flagged it as a concern, though some consumers prefer to avoid DEA derivatives due to historical nitrosamine concerns in poorly formulated products.
Research notes
Limited peer-reviewed studies specifically on olivamide DEA, but it is structurally similar to other fatty acid DEA amides, which have been reviewed by the Cosmetic Ingredient Review (CIR) panel and deemed safe for rinse-off use. No significant irritation or sensitization data has been reported.
Common label clues
- Typical concentration
- 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) with no specific restrictions, though DEA compounds are monitored for nitrosamine contamination.
- Common uses
- Shampoos, Body washes, Facial cleansers, Liquid soaps
- Environmental note
- Derived from olive oil, a renewable resource, and is biodegradable, but the chemical processing involves energy and reagents that reduce its eco-friendly profile.
Good to know
- Olivamide DEA is often used as a replacement for cocamide DEA, which has more controversy around impurities.
- It is biodegradable and considered environmentally friendlier than some petroleum-based surfactants.
