SCI functions as a surfactant, which means it lowers the surface tension between substances.
In cleansers like bar soaps and liquid body washes, it plays a crucial role. It emulsifies oils and dirt on the skin, allowing them to be easily rinsed away. What sets it apart is its mildness.
It is gentle enough for use on sensitive skin, as it doesnt strip the skin of its natural oils excessively. This helps maintain the skin's moisture barrier, leaving the skin feeling soft and supple after cleansing, rather than tight and dry.
In baby products, its safety and mildness are especially prized. It is commonly found in baby shampoos and washes, providing a gentle cleanse to delicate baby skin.
For those with eczema or other skin conditions, products formulated with SCI can offer relief, as they clean without irritating or exacerbating existing skin issues.
In shaving creams, it aids in creating a smooth lather that lubricates the skin, reducing friction during shaving and minimizing the risk of nicks and cuts.

Sodium Cocoyl Isethionate (CAS 61789-32-0) is an ingredient that combines excellent cleansing power with skin-friendly attributes.
It has become a go-to choice for formulators aiming to create high-quality, gentle personal care products that cater to a wide range of consumers, from babies to those with sensitive skin.
