Sodium Cocoyl Isethionate (SCI) is a mild surfactant derived from coconut oil, commonly used in cleansing and foaming formulations like shampoos, body washes, and facial cleansers. With an active matter concentration of 80%, it provides excellent cleansing properties without the harshness commonly associated with traditional surfactants.
SCI is known for its gentle, non-stripping nature, making it ideal for sensitive skin formulations. It forms rich, creamy lather that helps remove oils, dirt, and impurities from the skin and hair while preserving moisture and softness. Its mildness, combined with its effective cleansing abilities, makes it an excellent choice for products designed for dry or sensitive skin.
SCI is also biodegradable and environmentally friendly, making it suitable for eco-conscious formulations.

FORMULATION GUIDELINES
| INCI | Sodium Cocoyl Isethionate |
|---|---|
| Type | Anionic surfactant |
| Solubility | Water-soluble |
| Use Rate | 5.0–10.0% typical, depending on the desired foaming and viscosity. |
| Best Phase | Water phase (or mix with other surfactants in the surfactant phase) |
| pH Compatibility | Works best in formulations with a pH of 4.5–6.5, ideal for most cleansing products. |
| Temperature Tolerance | Stable in typical formulation temperatures. Avoid heating above 40°C to preserve active surfactant properties. |
| Pro Tip | For mild formulations, combine Sodium Cocoyl Isethionate with other mild surfactants such as Decyl Glucoside or Cocamidopropyl Betaine. Adjust the surfactant blend for optimal foam quality, cleansing power, and skin feel. SCI is effective in both gel and liquid formulations, and it provides excellent cleansing without leaving the skin feeling dry or tight. |
| Appearance | White to off-white powder or flake (depending on the grade) |
| Stability Notes | SCI is stable in a wide range of formulations, but always test stability in your final product, particularly with regards to viscosity and foam quality. |
| Storage | Store in a cool, dry place, away from direct sunlight and moisture, in an airtight container. |
