Sodium Cocoyl Isethionate: The "new favorite" of gentle cleansing products
Sodium Cocoyl Isethionate(abbreviated as SCI), with the CAS number 61789-32-0 and the molecular formula C₂Na₆O₄₇S₂₀, is an anionic surfactant derived from natural coconut oil acid. It is a white powder or granule at room temperature.
The pH value of Sodium Cocoyl Isethionate is close to that of human skin, and its irritation is only 1/10 that of SLS. The foam is fine and stable, has excellent hardness resistance, and is fully biodegradable. It combines "gentle + environmentally friendly + multi-functional" features, and is becoming the preferred base material for high-end shampoos, infant and children's hygiene products, solid cleansers, and medical beauty dressings.
Sodium Cocoyl Isethionate (SCI) is hailed as the "green sulfate substitute". The global sales of SCI in 2024 are approximately 4.4 million US dollars, and it will increase to 5.4 million US dollars in 2031, with an annual growth rate of about 3%. In North America and European countries, it maintains a stable growth rate of 4%-5% driven by Clean Beauty and Halal certifications; while in Southeast Asia and the Middle East, there is an explosive demand for SCI from China, with export volume surging by 42% in 2024. In the global sales of Sodium Cocoyl Isethionate, shampoos, body washes, and baby care products account for more than 70%, but the product with the highest profit is still the one that produces more foam, works well in hard water, and has less skin irritation.
