Sodium Cocoyl Isethionate (SCI)
Benefits
- Produces an exceptionally rich, creamy, conditioning lather
- Extremely mild — cleanses effectively without stripping the skin’s natural moisture barrier
- Leaves skin feeling soft, smooth, and moisturized after rinsing
- Suitable for sensitive, dry, and reactive skin types
- Biodegradable and derived from renewable coconut sources
- Sulfate-free and free from harsh synthetic detergents
- Excellent primary surfactant for solid bars and powder cleansers
Uses

- Gentle facial cleansing bars
- Baby wash and sensitive skin cleansing products
- Bath fizzies and bubble bath powders
- Powder and solid surfactant blends
- Syndet (synthetic detergent) soap bars
How to Use
- For solid bars, melt or press SCI into your formulation at 30–80% of total batch weight alongside complementary surfactants and conditioning agents.
- SCI can be melted gently using a double boiler at low heat — do not overheat as it may degrade.
- Combine with co-surfactants such as Coco Glucoside or SLSA to customize lather and skin feel.
- Add conditioning agents, butters, and oils after melting to enhance the final bar’s moisturizing profile.
- Adjust the pH of your finished formulation to 4.5–6.5 for optimal skin compatibility.
Safety
- Avoid inhaling the powder form — work in a well-ventilated area and consider wearing a dust mask when handling
- For external use only — avoid ingestion
- Avoid direct contact with eyes; if contact occurs, rinse thoroughly with water
- Perform a patch test before use in new formulations
- Keep out of reach of children
- Store in a cool, dry place away from moisture — SCI absorbs humidity and may clump
