Palmamide DEA
INCI: PALMAMIDE DEA
Palmamide DEA boosts foam and thickens cleansers, but it can be mildly irritating and has raised some safety concerns due to potential DEA contamination.
In plain English
Palmamide DEA is an ingredient made from palm oil and a chemical called diethanolamine (DEA). It's added to soaps, shampoos, and face washes to make them foam more and feel thicker. While it helps create a rich lather, some people find it drying or irritating, and there are concerns about DEA impurities forming potentially harmful compounds.

Quick decision guide
Useful, but context matters
Palmamide 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 Palmamide 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
Palmamide DEA is a semi-synthetic surfactant and foam booster created by reacting fatty acids from palm oil with diethanolamine (DEA). It belongs to a class of ingredients called alkanolamides, which are widely used in personal care products to improve texture and lather.
How it works
In a cosmetic product, Palmamide DEA works by stabilizing foam and increasing the thickness of liquid formulas. It helps bubbles last longer and gives the product a creamy, luxurious feel. It also helps other cleansing ingredients work together more effectively.
Pros
Boosts lather
Creates a rich, stable foam that many people associate with effective cleansing.
Improves texture
Thickens liquid products, giving them a more luxurious feel without needing extra thickeners.
Cons and cautions
Potential irritation
Can be drying or irritating for sensitive skin, especially with frequent use.
DEA concerns
May contain or form diethanolamine (DEA) impurities, which have been linked to potential health risks in high doses.
Best for
- People who enjoy rich, foamy cleansers
- Those with normal to oily skin looking for effective cleansing
Use caution if
- Individuals with sensitive or eczema-prone skin
- Anyone concerned about potential nitrosamine formation
Usage tips
Safety summary
Palmamide DEA is generally considered safe in rinse-off products at typical concentrations, but it can be mildly irritating and has theoretical concerns about nitrosamine formation. Regulatory bodies have set limits on DEA content to mitigate risks.
Research notes
Studies show that DEA-based ingredients can form nitrosamines under certain conditions, but the risk is low in properly formulated products. The CIR panel and EU SCCS have reviewed the data and concluded it is safe for rinse-off use at low levels.
Common label clues
- Typical concentration
- 1% to 5%
- Regulatory status
- Approved for use in cosmetics in the US and EU, but the EU restricts DEA content to minimize nitrosamine formation. The Cosmetic Ingredient Review (CIR) panel has deemed it safe as used in rinse-off products.
- Common uses
- Shampoos, Body washes, Facial cleansers, Bubble baths
- Environmental note
- Palm oil sourcing can contribute to deforestation; look for RSPO-certified palm derivatives if environmental impact is a concern.
Good to know
- Palmamide DEA is often derived from palm oil, so look for sustainable sourcing certifications if that matters to you.
- Many brands have moved away from DEA-based ingredients due to consumer concerns, but it is still considered safe at low levels by regulators.
