Ingredient review
Potassium Cyclocarboxypropyloleate
INCI: POTASSIUM CYCLOCARBOXYPROPYLOLEATE
An effective synthetic cleanser that can be drying for some skin types, but is generally safe when used in rinse-off products.
In plain English
Potassium Cyclocarboxypropyloleate is a man-made ingredient that helps cleansers foam up and lift away dirt, oil, and makeup from your skin. It's a type of surfactant, which means it works by breaking the surface tension between water and oil, allowing them to mix so impurities can be rinsed away. Because it's a strong cleanser, it can sometimes strip the skin of its natural oils, leading to dryness or irritation, especially for those with sensitive or dry skin.

Potassium Cyclocarboxypropyloleate 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 Potassium Cyclocarboxypropyloleate.
- 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.

What it is
A synthetic anionic surfactant derived from oleic acid, modified to improve its cleansing and foaming properties. It is commonly used in rinse-off personal care products.
How it works
It reduces the surface tension between water and oil, allowing oily dirt and sebum to be emulsified and washed away. Its molecular structure has a water-loving head and an oil-loving tail, which surrounds and lifts impurities off the skin.
Pros
Effective cleanser
Removes dirt, oil, and makeup efficiently, making it suitable for oily or combination skin types.
Good foam quality
Creates a rich lather that many users find satisfying and helps spread the product evenly.
Cons and cautions
Potential for dryness
Its strong cleansing action can strip natural oils, leading to tightness or flakiness, especially in dry climates.
Irritation risk
May cause stinging or redness in sensitive skin, particularly if used in high concentrations or left on skin too long.
Best for
- People with normal to oily skin looking for a thorough cleanse
- Those who prefer foaming cleansers and don't have sensitivity issues
Use caution if
- Individuals with very dry, compromised, or sensitive skin
Usage tips
Safety summary
Generally safe for use in rinse-off cosmetics at typical concentrations. Mild to moderate irritation potential exists, especially for sensitive skin. Avoid contact with eyes.
Research notes
Limited peer-reviewed studies specifically on this ingredient, but it is structurally similar to other anionic surfactants with well-documented cleansing and irritation profiles. Safety assessments by cosmetic ingredient review panels support its use.
Common label clues
- Typical concentration
- Typically 1–10% in rinse-off formulations
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng) as a surfactant, with no specific restrictions at typical use levels.
- Common uses
- Facial cleansers, Body washes, Shampoos
- Environmental note
- As a synthetic surfactant, its biodegradability may vary; check product formulations for eco-friendly claims.
Good to know
- This ingredient is often combined with milder surfactants to balance cleansing power and gentleness.
- It is not typically found in leave-on products like lotions or serums.
