Disodium Coceth-3 Sulfosuccinate
INCI: Disodium Coceth-3 Sulfosuccinate
A gentle, coconut-derived surfactant that cleans without stripping the skin — ideal for sensitive or dry skin types.
In plain English
Disodium Coceth-3 Sulfosuccinate is a mild cleansing ingredient made from coconut oil. It helps create a soft foam in cleansers and shampoos while being much gentler than traditional sulfates like SLS. Think of it as a kinder way to wash your face or body — it removes dirt and oil without leaving your skin feeling tight or dry.

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 Coceth-3 Sulfosuccinate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 produced by reacting coconut oil derivatives with sulfosuccinic acid. It belongs to the sulfosuccinate family, known for their mild cleansing properties.
How it works
It lowers the surface tension between water and oil, allowing dirt, sebum, and makeup to be rinsed away. Its large molecular structure makes it less penetrating and less irritating than harsher surfactants.
Pros
Very gentle on skin
Its large molecular structure means it doesn't penetrate the skin barrier easily, reducing irritation and dryness — great for daily use.
Coconut-derived and biodegradable
Made from renewable coconut oil, it is considered more environmentally friendly than many petroleum-based surfactants.
Cons and cautions
Milder cleansing power
It may not fully remove heavy makeup or waterproof sunscreen on its own, often requiring a double-cleansing routine.
Can feel less foamy
Some users accustomed to sulfate-rich cleansers may find the foam less rich or satisfying.
Best for
- People with dry, sensitive, or eczema-prone skin
- Anyone looking for a gentle daily facial cleanser
Use caution if
- Those who prefer a very high-foam, squeaky-clean feel may find it too mild
Usage tips
Safety summary
Disodium Coceth-3 Sulfosuccinate is widely regarded as safe and non-irritating. The Cosmetic Ingredient Review (CIR) panel has reviewed sulfosuccinates and found them safe for use in rinse-off products at current concentrations. It is not a known allergen or sensitizer.
Research notes
Sulfosuccinates are well-studied as mild surfactants. Research shows they cause significantly less skin barrier disruption than sodium lauryl sulfate (SLS). However, most studies are industry-funded or older; newer independent research is limited.
Common label clues
- Typical concentration
- 1–10% in rinse-off products
- Regulatory status
- Approved for use in cosmetics worldwide, including by the U.S. FDA and EU CosIng database. No known restrictions at typical use levels.
- Common uses
- Facial cleansers, Body washes, Shampoos, Baby care products
- Environmental note
- Derived from coconut oil and considered biodegradable, though the ethoxylation process (PEG) may raise minor environmental concerns for some consumers.
Good to know
- Often listed near the middle or end of ingredient lists because it is used at lower concentrations.
- Commonly found in baby shampoos and 'tear-free' formulas due to its low eye irritation potential.
