Applications of Sodium Cocoyl Isethionate
Soap bars
Sodium Cocoyl Isethionate is used in “combo bar” applications at levels of 2 – 60% to provide lathering in hard or soft water similar to soaps in soft water.
Its dense lather is additive to that of soap.
Such mixtures are mild to the skin and are relatively non-drying.
Shampoos
The properties of Sodium Cocoyl Isethionate also make it an excellent cleansing agent for shampoos.
Sodium Cocoyl Isethionate imparts softness and manageability to hair besides compatibility with hard water, good cleaning properties, and excellent lathering,
Bubble baths
Sodium Cocoyl Isethionate is recommended for use in bubble baths as a high foaming agent.
Sodium Cocoyl Isethionate provides longer-lasting suds, even in the presence of soap, and is mild to skin.
Performance Benefits
Sodium Cocoyl Isethionate has limited solubility in soft and hard water.
Sodium Cocoyl Isethionate is optimally stable in aqueous formulations from pH 6-8 at ambient temperature.
Sodium Cocoyl Isethionate is naturally derived from coconut and is considered ‘readily biodegradable’ according to OECD Guidelines
