Ingredient review
Minkamide DEA
INCI: Minkamide DEA
Minkamide DEA is a foam booster from mink oil, but it's rarely used today due to ethical concerns and potential irritation.
In plain English
Minkamide DEA is a chemical made from mink oil that helps create foam and thicken products like shampoo and body wash. It's a type of surfactant, which means it helps water mix with dirt and oil so they can be rinsed away. However, it's not very common anymore because it can be irritating to some skin types and raises ethical questions about animal-derived ingredients.

Quick decision guide
Read the cautions before using
Minkamide DEA can be useful, but watch for some irritation potential and possible clogging concerns.
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 Minkamide 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
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Minkamide DEA is a semi-synthetic surfactant created by reacting mink oil (a fatty oil from minks) with diethanolamine (DEA). It belongs to the alkanolamide family of surfactants, which are used to boost foam and stabilize formulas.
How it works
In a cosmetic product, Minkamide DEA sits at the interface between water and oil, helping to lower surface tension. This allows the product to create a rich, stable lather and to better lift dirt and oil from skin and hair. It also thickens the formula, giving it a more luxurious feel.
Pros
Effective foam booster
Creates a dense, stable lather that makes cleansing feel satisfying and helps distribute the product evenly.
Improves product feel
Thickens the formula so shampoos and washes feel more luxurious and less watery on the skin.
Cons and cautions
Potential irritant
DEA-based surfactants can cause stinging or irritation, especially for those with eczema or very sensitive skin.
Animal-derived source
Made from mink oil, which raises ethical concerns for vegans and those preferring plant-based ingredients.
Best for
- Those who tolerate mild surfactants well
- People using rinse-off products who want a creamy lather
Use caution if
- Individuals with sensitive or reactive skin
- Those avoiding animal-derived ingredients
- Acne-prone skin types
Usage tips
Safety summary
Minkamide DEA is considered safe in rinse-off products at low concentrations, but it can cause mild to moderate irritation in sensitive individuals. The DEA component has been linked to potential nitrosamine formation, though this is controlled by purity standards. Overall, it's a dated ingredient with better alternatives available.
Research notes
Limited modern research on Minkamide DEA specifically. Studies on similar DEA-based surfactants indicate moderate skin irritation potential. The Cosmetic Ingredient Review (CIR) has evaluated DEA compounds and found them safe in rinse-off products when formulated to minimize nitrosamine contamination.
Common label clues
- Typical concentration
- Typically 1–5% in rinse-off products
- Regulatory status
- Allowed in cosmetics in the US and EU, but subject to purity limits on DEA and nitrosamine content. Not recommended for use in products intended for children under 3 in some regions.
- Common uses
- Shampoos, Body washes, Facial cleansers, Bubble baths
- Environmental note
- Mink farming for oil raises animal welfare concerns. Plant-based alternatives have a lower environmental footprint.
Good to know
- Minkamide DEA is less common today due to ethical sourcing concerns and the availability of effective plant-based alternatives.
- DEA (diethanolamine) in this ingredient has been scrutinized for potential contamination with nitrosamines, though this is more a concern for manufacturing than finished products.
