What Is Sodium Cocoyl Isethionate?

Sodium cocoyl isethionate is a cleansing agent derived from coconut oil.

What Is The Chemical Composition of Sodium Cocoyl Isethionate?

In this section, we walk you through the chemical characteristics of Sodium Cocoyl Isethionate, while laying focus on its iconic and non-iconic traits. We then take a quick look at how this mild cleansing agent is manufactured for an assortment of personal care products. 

Ionic and Nonionic Characterstics of Sodium Cocoyl Isethionate (SCI)  

Sodium Cocoyl Isethionate is an anionic surfactant extracted from coconut oil. It contains primarily sodium salt of isethionic acid, that ensures its surfactant properties. The structure carries a hydrophilic isethionate group and a hydrophobic alkyl group from coconut, that elevates its emulsifying capabilities.  

Owing to its distinct chemical structure, Sodium Cocoyl Isethinonate showcases both ionic and nonionic properties, ensuring its mildness. It carries exceptional foaming properties while being gentle on the skin, making it a great choice for personal care products. SCI is often categorized alongside other surfactants because it ensures a thorough cleanse without dying your skin.

Manufacturing Process

The manufacturing of sodium cocoyl isethionate includes these main steps. First and foremost, coconut oil undergoes hydrolysis to create fatty acids, which are then reacted with isethionic acid. This chemical reaction forms an ester, followed by neutralization with sodium hydroxide to create the final salt form. The purity and quality of SCI depend on regulating the reaction condition, like temperature and pH levels. After synthesis, the product is dried and made into a powder, ensuring ease of use in formulations. This method creates a high-quality surfactant utilized in shampoos, body washes, and facial cleansers, bath bombs, and baby care products.
