Ingredient review
Stearamide MIPA
INCI: Stearamide MIPA
Stearamide MIPA helps thicken and stabilize cleansers, but may be mildly irritating or clog pores for some skin types.
In plain English
Stearamide MIPA is a synthetic ingredient added to shampoos and body washes to make them thicker and produce more lather. It is a type of amide derived from stearic acid, a fatty acid found in animal or plant fats. While it helps create a rich, creamy texture, it can sometimes cause irritation or clog pores, especially in people with sensitive or acne-prone skin.

Quick decision guide
Useful, but context matters
Stearamide MIPA 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 Stearamide MIPA.
- 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
Stearamide MIPA is a synthetic compound made by reacting stearic acid with monoisopropanolamine (MIPA). It belongs to a class of ingredients called alkanolamides, which are used to modify the viscosity and foaming properties of cleansing products.
How it works
In a cosmetic product, Stearamide MIPA acts as a thickener and foam booster. It increases the viscosity of liquid cleansers, giving them a richer, more luxurious feel, and helps stabilize foam so the product lathers well during use. It also helps other cleansing ingredients work together more effectively.
Pros
Improves product feel
Creates a thick, luxurious texture in cleansers and shampoos, making them feel more substantial and pleasant to use.
Boosts lather
Helps produce a stable, creamy foam that many people associate with effective cleansing, improving the user experience.
Cons and cautions
May irritate sensitive skin
Can cause redness, itching, or stinging in people with sensitive or compromised skin barriers, especially with frequent use.
Potential pore clogging
Has a moderate comedogenic rating, meaning it may contribute to clogged pores and breakouts in acne-prone individuals.
Best for
- People who enjoy rich, creamy cleansers and shampoos
- Those without sensitive or acne-prone skin
Use caution if
- Individuals with sensitive, reactive, or acne-prone skin
- Those seeking exclusively natural or plant-based ingredients
Usage tips
Safety summary
Stearamide MIPA is considered safe for use in rinse-off cosmetics at typical concentrations. However, it has moderate irritation and comedogenic potential, so it may not be ideal for sensitive or acne-prone skin. Regulatory bodies have not flagged it as a high-risk ingredient, but individual sensitivity varies.
Research notes
Research on Stearamide MIPA is limited. Most safety data come from general studies on alkanolamides, which indicate low acute toxicity but potential for mild skin irritation. No significant carcinogenic or reproductive toxicity has been reported in cosmetic use. More targeted studies are needed.
Common label clues
- Typical concentration
- 0.5% to 5%
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) within typical concentration limits. No specific restrictions beyond general cosmetic safety requirements.
- Common uses
- Shampoos, Body washes, Facial cleansers, Bar soaps
- Environmental note
- Stearamide MIPA is synthetic and not readily biodegradable. Its production involves petrochemical or plant-derived stearic acid, with moderate environmental impact depending on sourcing.
Good to know
- Stearamide MIPA is often used in combination with other surfactants to balance cleansing and mildness.
- It is not the same as Stearamide, which is a different ingredient used as an opacifying agent.
- Some formulations may list it as 'Stearamide MIPA' or simply 'MIPA' on the label.
