INCI: Coco-Hydroxysultaine
A gentle, coconut-derived surfactant that cleanses without stripping the skin or scalp.
In plain English
Coco-Hydroxysultaine is a mild cleansing ingredient made from coconut oil. It helps create a rich, creamy lather in shampoos and body washes while being much less drying than traditional sulfates. It's often used in 'gentle' or 'sulfate-free' formulas because it cleans effectively without stripping away your skin's natural moisture barrier.

What it is
Coco-Hydroxysultaine is an amphoteric surfactant, meaning it can work in both acidic and alkaline formulas. It is derived from coconut fatty acids and is known for its mildness and compatibility with other cleansing agents.
How it works
It works by reducing the surface tension between water and oil, allowing dirt, sebum, and makeup to be rinsed away. Its amphoteric nature makes it gentle on the skin and eyes, and it also helps boost and stabilize foam in a formula.
Pros
Very gentle on skin
Coco-Hydroxysultaine is one of the mildest surfactants available, making it ideal for sensitive skin and daily use without causing irritation or tightness.
Eco-friendly source
Derived from renewable coconut oil, it is biodegradable and considered a more sustainable choice compared to petroleum-based cleansers.
Cons and cautions
Mild cleansing only
It may not thoroughly remove heavy makeup or waterproof sunscreen on its own, often requiring a double-cleanse or a stronger co-surfactant.
Potential for coconut allergy
Although rare, individuals with a coconut allergy may experience a reaction, so patch testing is recommended for those with known sensitivities.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
- Anyone who prefers plant-derived ingredients
Use caution if
- Individuals with known coconut allergies (rare, but possible)
- Those needing a deep-cleansing formula for heavy oil or makeup
