Frequently Asked Technical Questions (FAQ)

1. What is the chemical structure of Sodium cocoyl isethionate and its main functional groups?: Sodium cocoyl isethionate is a sodium salt of coconut fatty acid esterified with isethionic acid, containing ester (–COO–) and sulfonate (–SO₃–) groups. These provide surface activity and mild cleansing.
2. What particle sizes and physical forms are available for industrial customization?: SCI is available as powder (<400μm), granular (1–4 mm), and noodles/flake (2–5 mm) forms. This flexibility enables precise process selection for extrusion, spray drying, or bar pressing lines.
3. Which global standards does your Sodium cocoyl isethionate comply with?: All products strictly follow ISO 9001:2015, ISO 22716 for cosmetics GMP, EU REACH, and the latest FDA ingredient listings (21CFR172.829). Custom batches can comply with EcoCert/COSMOS as requested.
4. How is purity determined and monitored?: Via gas chromatography (GC) and HPLC analysis for active content. Each batch documented with COA and validated with third-party lab tests, ensuring >85% actives and minimal byproducts (sulfate <1.5%).
5. What storage and lifetime parameters does SCI require?: Store in sealed, moisture-proof packaging at 10–30°C. Avoid direct sunlight. Shelf life is 24 months min; granule and powder types show negligible yellowing on prolonged storage.
6. Can Sodium cocoyl isethionate be used in high-hardness or industrial water systems?: Yes. SCI retains >95% foam and solubility even at water hardness of 250–400 ppm CaCO₃. Its hard-water tolerance makes it widely used in metal, textile, and water-treatment cleaning.
7. Are there any known regulatory or safety concerns?: SCI is classified as "safe for intended cosmetic & cleaning uses" by the US CIR, EU SCCS, and Japan JSQI. Not a toxin, carcinogen, or REACH SVHC.
Note: It is biodegradable & non-bioaccumulative (OECD 301).
