DESCRIPTION
SCI (Sodium Cocoyl Isethionate) Ecocert: mild solid surfactant that creates dense, creamy foam, sulfate-free. Used in solid and liquid shampoo, cleansing bars, body washes and facial cleansers.
1. Product description:
SCI is a mild anionic surfactant in solid form, biodegradable and sulfate-free. It stands out for its high tolerance to hard water and its ability to produce dense, rich, creamy foam. It leaves a conditioning effect and a silky feel on both skin and hair, making it the star ingredient for solid cosmetics.
Practical formulation guide
Usage level: Guideline range: 8–20 % total active matter in shampoo and body wash; 3–10 % in gentle facial cleansers. Always calculate based on the product's active matter.
How to use and incorporate: Add the surfactant to the water (not the water onto the surfactant) with slow stirring to avoid excess foam. If solid or paste, melt or dissolve first in warm water. Adjust the pH at the end (5–6.5 for facial and hair products) and the viscosity with salt (sodium chloride 0.5–2 %) or a thickener.
Formulation tips:
- Combining a primary surfactant with a secondary one (betaine, glucoside, amphoteric) improves mildness, foam and viscosity.
- Anionic and cationic surfactants may be incompatible; check clarity and stability when combining them.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Compatible with other anionic, amphoteric and nonionic surfactants, conditioning polymers and most extracts and fragrances.
Storage: 8. Storage conditions: Store in airtight containers in a cool, strictly dry place. As a fine powder, it tends to cake if it comes into contact with ambient moisture. Shelf life: 24 months from the date of manufacture.
Precautions: 9. Handling precautions: Because SCI powder is very fine and easily airborne, a respirator (N95 or higher), safety glasses and gloves are mandatory when weighing and handling it to avoid temporary respiratory irritation.
Technical information for formulators: This sheet describes industrial uses of the raw material in the development of cosmetic products. It is not an efficacy claim for any finished product. The person responsible for the formulation must validate the concentration, compatibility and claims of their product in accordance with applicable regulations.
