Ingredient review
Cocamidopropyl Morpholine
INCI: Cocamidopropyl Morpholine
Cocamidopropyl Morpholine is an effective emulsifier and surfactant, but may cause irritation for sensitive skin types, especially in high concentrations.
In plain English
Cocamidopropyl Morpholine is a synthetic ingredient made from coconut oil and morpholine, a chemical compound. It helps mix oil and water in products like cleansers and shampoos, creating a smooth texture and helping to remove dirt and oil from skin and hair. While generally considered safe, it can be irritating for some people, particularly those with sensitive skin or allergies.

Quick decision guide
Useful, but context matters
Cocamidopropyl Morpholine 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 Cocamidopropyl Morpholine.
- 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

What it is
Cocamidopropyl Morpholine is a semi-synthetic surfactant and emulsifier derived from coconut oil and morpholine. It is commonly used in personal care products to help blend oil and water and to improve cleansing and foaming properties.
How it works
In a cosmetic product, Cocamidopropyl Morpholine reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. This helps cleansers effectively remove dirt, oil, and makeup, and gives the product a smooth, creamy texture.
Pros
Effective emulsifier
Helps create stable, smooth formulas that mix oil and water, improving product texture and performance.
Good cleansing power
Removes dirt, oil, and makeup effectively, making it useful in shampoos and body washes.
Cons and cautions
Potential irritation
Can cause stinging, redness, or dryness in people with sensitive skin, especially at higher concentrations.
Impurity concerns
Morpholine derivatives may contain trace impurities like nitrosamines, though levels are regulated and generally low in finished products.
Best for
- People with normal to oily skin looking for effective cleansers
- Those who tolerate standard surfactant-based products well
Use caution if
- Individuals with very sensitive skin or known allergies to coconut-derived surfactants
Usage tips
Safety summary
Cocamidopropyl Morpholine is considered safe for use in cosmetics at typical concentrations, but can cause mild to moderate irritation in sensitive individuals. Regulatory bodies set limits on impurities to ensure safety.
Research notes
Studies indicate that Cocamidopropyl Morpholine is an effective surfactant with low acute toxicity, but it may cause skin sensitization in some people. The Cosmetic Ingredient Review (CIR) panel has reviewed it and found it safe when formulated to avoid irritation.
Common label clues
- Typical concentration
- Typically 1–5% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US and EU, with concentration limits and purity standards to minimize impurities.
- Common uses
- Cleansers, Shampoos, Body washes, Lotions
- Environmental note
- Derived partly from coconut oil, a renewable resource, but the morpholine component is synthetic and may have moderate biodegradability.
Good to know
- Cocamidopropyl Morpholine is not the same as Cocamidopropyl Betaine, which is generally milder.
- It is often used in combination with other surfactants to balance cleansing and mildness.
