Ingredient review
Lanolinamide DEA
INCI: LANOLINAMIDE DEA
Lanolinamide DEA helps create rich lather and stabilize mixtures, but it may be mildly irritating or comedogenic for sensitive or acne-prone skin.
In plain English
Lanolinamide DEA is a helper ingredient made from lanolin (the waxy oil from sheep's wool) and diethanolamine. It helps oil and water mix together in products like shampoos and cleansers, and it makes the foam feel creamier. However, it can be a bit harsh for very sensitive skin and may clog pores in some people.

Quick decision guide
Useful, but context matters
Lanolinamide 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 Lanolinamide 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
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Lanolinamide DEA is a semi-synthetic compound created by reacting lanolin fatty acids with diethanolamine. It acts as a surfactant and emulsifier, helping to blend oil and water phases in a formula while also boosting foam.
How it works
In a cosmetic product, Lanolinamide DEA sits at the boundary between oil and water droplets, reducing surface tension so they mix smoothly. It also stabilizes foam bubbles, giving cleansers a richer, more luxurious lather.
Pros
Enhances lather
Creates a creamy, stable foam that makes cleansing feel more satisfying.
Stabilizes formulas
Helps keep oil and water mixed, preventing separation in bottles.
Cons and cautions
Potential irritant
May cause mild stinging or redness on sensitive or compromised skin.
Comedogenic risk
Can clog pores in some individuals, especially those prone to breakouts.
Best for
- People with normal to oily skin who enjoy rich lather
- Those using rinse-off products like shampoos and body washes
Use caution if
- Individuals with lanolin allergy or sensitivity
- Acne-prone skin that reacts to waxy ingredients
Usage tips
Safety summary
Lanolinamide DEA is generally safe for most people in rinse-off products at low concentrations. However, it can cause mild irritation or clog pores in sensitive or acne-prone individuals. Those with lanolin allergies should avoid it.
Research notes
Studies indicate that DEA derivatives can be mild irritants at high concentrations, but cosmetic use levels are considered safe. The Cosmetic Ingredient Review (CIR) panel has reviewed related DEA compounds and found them safe when formulated properly.
Common label clues
- Typical concentration
- 0.5% to 5% of the formula
- Regulatory status
- Approved for use in cosmetics by the FDA and the European Commission, with concentration limits in some regions to minimize irritation risk.
- Common uses
- Shampoos, Body washes, Facial cleansers, Lotions
- Environmental note
- Lanolin is a byproduct of wool production, making it a renewable resource, but the DEA component may have moderate environmental persistence.
Good to know
- Lanolinamide DEA is related to diethanolamine (DEA), which has raised some safety concerns, but cosmetic-grade DEA derivatives are considered safe at low concentrations.
- This ingredient is not common in modern 'clean' beauty formulations, which often prefer plant-based alternatives.
