Sodium Cocoyl Isethionate, SCI. Ingredient to die for!

Scientific Facts: 

Sodium Cocoyl Isethionate is a fine white powder. It has a mild odor and can be prepared from the fatty acid mixture from coconut oil.

Commonly known as Baby Foam due to its exceptional mildness, Sodium Cocoyl Isethionate Raw Material is a surfactant comprised of a type of sulphonic acid called Isethionic Acid as well as the fatty acid – or sodium salt ester – obtained from Coconut Oil. It is a traditional substitute for sodium salts that are derived from animals, namely sheep and cattle.

Sodium Cocoyl Isethionate exhibits high foaming ability, producing a stable, rich, and velvety lather that does not dehydrate the skin, making it ideal for adding water-free well as skincare, haircare, and bath products. This high-performance surfactant, which is equally effective in both hard and soft water, is a popular choice for addition to liquid shampoos and bar shampoos, liquid soaps and bar soaps, bath butters, and bath bombs, and to shower gels, to name a few foaming products.

This lightly-scented and conditioning cleansing agent is gentle enough for use on babies’ delicate skin, making it an ideal surfactant for makeup and personal care products and natural toiletries. Its emulsifying property, which allows water and oil to mix, makes it a popular ingredient in soaps and shampoos. It encourages dirt to attach itself to them, making it easier for it to be washed away. Its deluxe foaming capacity and conditioning effects leave the hair and skin feeling hydrated, soft, and silky-smooth.

To incorporate Sodium Cocoyl Isethionate into a formulation, it is recommended that the chips be crushed before melting, increasing their melting rate. Next, Sodium Cocoyl Isethionate must be heated slowly on low heat to easily mix with other surfactants. It is recommended that the surfactant phase be mixed using a high shear stick blender. This approach helps to prevent the excess foaming that could potentially occur if the stick blender is used to mix all ingredients together at once. Finally, the surfactant mixture can be added to the rest of the formulation.
