Ingredient review
Capramide DEA
INCI: CAPRAMIDE DEA
Capramide DEA helps create rich lather and thicker formulas, but it may be irritating for sensitive skin and can be contaminated with potentially harmful impurities.
In plain English
Capramide DEA is a synthetic ingredient that makes cleansers and shampoos foam more and feel thicker. It's related to cocamide DEA, which has raised safety concerns. While it's effective at improving texture, it can be drying or irritating, especially for sensitive skin. Some studies also worry about possible contamination with a cancer-causing chemical called DEA, though the risk is low in rinse-off products.

Quick decision guide
Useful, but context matters
Capramide DEA can be useful, but watch for some irritation potential.
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 Capramide 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
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
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
Capramide DEA is a diethanolamide made from capric acid (a fatty acid from coconut or palm oil) and diethanolamine (DEA). It's a synthetic surfactant used to boost foam and thicken liquid cleansers.
How it works
It works by reducing the surface tension of water, helping oils and dirt mix with water so they can be rinsed away. It also interacts with other surfactants to create a stable, rich lather and a thicker product consistency.
Pros
Great foam booster
Creates a rich, creamy lather that many people associate with effective cleansing.
Improves product texture
Thickens liquid formulas so they feel more luxurious and are easier to apply without dripping.
Cons and cautions
Potential skin irritation
Can strip natural oils and cause dryness, redness, or stinging, especially for sensitive skin types.
DEA contamination risk
May contain trace amounts of DEA, which can react with other ingredients to form potentially carcinogenic nitrosamines.
Best for
- People with normal to oily skin who enjoy rich lather
- Those using rinse-off products and not prone to sensitivity
Use caution if
- People with sensitive, dry, or eczema-prone skin
- Anyone avoiding DEA-derived ingredients due to contamination concerns
Usage tips
Safety summary
Capramide DEA is considered safe in rinse-off products at low concentrations, but it can cause irritation and dryness. The main concern is potential contamination with DEA and nitrosamines, which are possible human carcinogens. Regulatory bodies limit DEA levels to mitigate this risk.
Research notes
Studies show capramide DEA can cause mild to moderate skin irritation in some individuals. Research on DEA indicates that high doses in animal studies led to liver and kidney effects, but human exposure from cosmetics is much lower. The Cosmetic Ingredient Review (CIR) panel has deemed DEA-based ingredients safe as used in rinse-off products.
Common label clues
- Typical concentration
- 1–5%
- Regulatory status
- Allowed in cosmetics in the US and EU, but DEA is restricted to low levels (max 0.5% in rinse-off products in the EU) to limit nitrosamine contamination.
- Common uses
- Shampoos, Body washes, Facial cleansers, Bubble baths
- Environmental note
- Capramide DEA is not readily biodegradable in all conditions, which can contribute to aquatic toxicity. Plant-derived capric acid is renewable, but the synthetic DEA component raises environmental concerns.
Good to know
- Capramide DEA is often used as a replacement for cocamide DEA, which has been more heavily scrutinized.
- The European Union restricts DEA in cosmetics to minimize nitrosamine formation.
- Many brands now voluntarily avoid DEA-based ingredients due to consumer concerns.
