Sodium Cocoylisethionate
What is Sodium Cocoylisethionate?
Sodium Cocoylisethionate is a mild, anionic surfactant derived from coconut fatty acids and isethionic acid, commonly used in cleansers, shampoos, and body washes for its excellent foaming properties and gentle cleansing action. It effectively removes dirt and oils without stripping the skin's natural moisture barrier, making it suitable for sensitive and dry skin types. This ingredient is biodegradable and often preferred in sulfate-free formulations for its creamy lather and conditioning feel.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Foam booster
Enhances foam volume and creaminess and can stabilize lather, improving sensory feel and perceived cleansing in shampoos and wash-off products.
Cleansing agent
Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Foaming
Generates foam during use to help distribute the product and lift soils; typically delivered by surfactants that create stable bubbles under agitation.
