Disodium Caproamphodiacetate
INCI: Disodium Caproamphodiacetate
A gentle, low-irritation surfactant that helps cleanse without stripping the skin's natural moisture barrier.
In plain English
Disodium Caproamphodiacetate is a mild cleansing ingredient often used in soaps, shampoos, and facial washes. It belongs to a family of surfactants called amphoacetates, which are known for being gentle on skin and eyes. Unlike harsher detergents like sodium lauryl sulfate, this ingredient helps remove dirt and oil while leaving the skin feeling soft and not overly dry. It's especially popular in products for sensitive skin or baby care because it cleans effectively without causing irritation.

Quick decision guide
Useful, but context matters
Disodium Caproamphodiacetate is generally a lower-concern ingredient when the full formula suits your skin.
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 Disodium Caproamphodiacetate.
- 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 synthetic amphoteric surfactant derived from coconut oil and other fatty acids. It is part of the imidazoline-based surfactant family and is known for its mildness and compatibility with other cleansing ingredients.
How it works
It works by lowering the surface tension between water and oil, allowing dirt, sebum, and makeup to be lifted away from the skin and rinsed off. Its amphoteric nature means it can function in both acidic and alkaline formulas, making it versatile. It also helps stabilize foam and improve the feel of cleansers.
Pros
Extremely mild on skin
Disodium Caproamphodiacetate is one of the gentlest surfactants available, making it ideal for sensitive skin, eczema-prone skin, and baby care products.
Helps preserve moisture
Unlike harsh detergents that can strip natural oils, this ingredient cleans without leaving the skin feeling tight or dry, helping maintain a healthy moisture balance.
Cons and cautions
Not a standalone heavy-duty cleanser
On its own, it may not effectively remove heavy makeup, waterproof sunscreen, or long-wear products. It's often combined with other surfactants for better cleansing power.
Synthetic origin
It is manufactured through chemical processes, so it may not appeal to those seeking 100% natural or plant-derived ingredients in their skincare routine.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle daily cleanser that doesn't strip the skin
Use caution if
- Individuals who prefer completely natural or plant-based ingredients (this is synthetic)
Usage tips
Safety summary
Disodium Caproamphodiacetate is considered safe for use in cosmetics at typical concentrations. It has a low irritation and sensitization potential, making it suitable for sensitive skin and baby products. No significant safety concerns have been identified by major regulatory bodies.
Research notes
Research on amphoacetate surfactants, including Disodium Caproamphodiacetate, indicates they are among the mildest cleansing agents available. Studies show they cause less protein denaturation and lipid extraction compared to traditional anionic surfactants like SLS. However, most evidence comes from general surfactant safety data rather than ingredient-specific clinical trials.
Common label clues
- Typical concentration
- 1% to 10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics in the US (FDA), EU (CosIng), and many other regions. No known restrictions at typical use levels.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- As a synthetic surfactant, its biodegradability is moderate. It is not known to be a significant environmental concern at the low concentrations used in personal care products.
Good to know
- It is often used alongside other mild surfactants like Cocamidopropyl Betaine to create a balanced, low-irritation cleansing system.
- This ingredient is approved for use in many countries and is considered safe for rinse-off products at typical concentrations.
