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 Sodium Carboxymethyl Cocopolypropylamine.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
A semi-synthetic surfactant created by modifying coconut oil fatty acids with carboxymethyl and polypropylamine groups. It belongs to a class of mild cleansing agents often used in sulfate-free formulations.
How it works
It works by reducing the surface tension between water and oil, allowing water to mix with and rinse away oily dirt and sebum. Its molecular structure is designed to be less disruptive to the skin's natural lipid barrier compared to traditional sulfates.
Pros
Gentle on skin
Its mild nature makes it ideal for daily use, even on sensitive or compromised skin, reducing the risk of irritation or dryness.
Coconut-derived
Sourced from renewable coconut oil, it appeals to consumers looking for plant-based or naturally derived ingredients in their skincare.
Cons and cautions
Lower foam
It produces a modest lather compared to sulfates, which may be less satisfying for those who associate foam with cleansing effectiveness.
Cost factor
Formulations using this ingredient can be pricier due to its semi-synthetic production process, potentially increasing product cost.
Best for
- People with dry or sensitive skin looking for a gentle cleanser
- Anyone seeking a sulfate-free or mild cleansing option
Use caution if
- Those who prefer a rich, foamy lather may find this too subtle
