INCI: DISODIUM LAURETH-6 SULFOSUCCINATE
A gentle surfactant that cleanses effectively without the harshness of traditional sulfates, making it a good choice for sensitive skin.
In plain English

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 Laureth-6 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
Disodium Laureth-6 Sulfosuccinate is a semi-synthetic surfactant made by modifying fatty acids from coconut oil. It belongs to the sulfosuccinate family, known for their gentle cleansing properties.
How it works
It works by reducing the surface tension of water, allowing it to penetrate oils and dirt on the skin. The molecule has a water-loving head and an oil-loving tail, so it can surround and lift away impurities, which are then rinsed off with water.
Pros
Gentle on skin
This surfactant is much milder than sodium lauryl sulfate, reducing the risk of irritation, redness, and dryness, especially for sensitive skin types.
Good foam quality
It produces a rich, creamy lather that feels pleasant on the skin, making it a popular choice for luxurious cleansers and body washes.
Cons and cautions
Less effective on heavy oils
Because it's so gentle, it may not fully remove heavy makeup, waterproof sunscreen, or excess sebum on very oily skin, requiring a double-cleansing step.
Can be drying in high amounts
While generally mild, if used as the main surfactant in a formula without moisturizing ingredients, it can still strip some natural oils over time.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals with very oily skin who prefer a stronger, more stripping cleanser
- Those with known allergies to coconut-derived ingredients (rare)
