What it is
A synthetic, amphoteric surfactant derived from coconut oil and amino acids. It is part of the amphoacetate family, known for being exceptionally mild on skin and eyes.
How it works
It works by lowering the surface tension between water and oil, allowing dirt and sebum to be rinsed away. Because it is amphoteric (can act as either an acid or a base), it adjusts to the pH of the skin, reducing irritation potential.
Pros
Extremely mild
Rated very low on the irritation scale, making it ideal for sensitive skin and even baby products.
pH-friendly
Its amphoteric nature helps maintain a skin-friendly pH, reducing the risk of disruption to the acid mantle.
Cons and cautions
Limited cleansing power alone
On its own, it may not thoroughly remove heavy or waterproof makeup, so it's often blended with other cleansers.
Synthetic origin
Although derived partly from natural sources, it is a manufactured compound, which may be a concern for some natural-product enthusiasts.
Best for
- People with dry or sensitive skin
- Those looking for a sulfate-free cleanser
Use caution if
- Individuals seeking a single-ingredient heavy-duty makeup remover
