SODIUM COCOYL ISETHIONATE

CAS Number 61789-32-0 / 58969-27-0
Chem/IUPAC Name: Fatty acids, coco, 2-sulfoethyl esters, sodium salts
EINECS/ELINCS No: 263-052-5
COSING REF No: 79383
SODIUM COCOYL ISETHIONATE
Sodium Cocoyl Isethionate is a naturally-derived ingredient that comes from the fatty acids that are present in isethionic acid and coconut oil. These fatty acids are reacted with sodium isethionate and the mixture is heated to remove any water left behind. Further, the mixture is distilled to remove excess fatty acids. In its raw form, Sodium Cocoyl Isethionate appears as a fine white powder.

What is SODIUM COCOYL ISETHIONATE used for?

Sodium Cocoyl Isethionate is primarily a surfactant that is gentle on the surface and provides many benefits to skin and hair. It is thus commonly used in the cosmetic world.
  • Skin care: It differs from other surfactants in the way that it does not strip the skin of moisture, making it feel dehydrated. Instead, Sodium Cocoyl Isethionate produces a rich foam that does not dry out or irritate the skin upon application
  • Hair care: It produces a rich creamy lather that makes the products easier to spread and feel good. It also cleanses the shafts thoroughly because of its ability to mix well with both oil and water
  • Cosmetic products: It reduces the surface tension of the ingredients in a formulation - allowing them to mix well. This prevents the separation of oil based and water based ingredients and results in an even consistency of the cosmetic products
