Sodium cocoyl isethionate

When evaluating SCI, buyers must focus on the Active Matter content, which typically ranges from 80% to 85%. It is available in various physical forms such as powder, needles, granules, or flakes; needles are often preferred for reduced dust during manufacturing. Ensure the pH value (typically 5.0–6.5 in a 10% solution) aligns with your formulation requirements for 'syndet' bars or liquid cleansers. Additionally, verify the Free Fatty Acid content (usually 10%–14%), as this affects the creaminess and stability of the final lather.

As a chemical ingredient used in personal care, SCI must comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market. Suppliers should provide a comprehensive Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) compliant with GHS standards. For 'clean beauty' brands, look for RSPO (Roundtable on Sustainable Palm Oil) certification if palm derivatives are used, and ensure the product is COSMOS or ECOCERT validated if targeting the organic cosmetics sector.

Request a Certificate of Analysis (COA) for the specific batch being shipped. Perform a solubility test and a foam height test (Ross-Miles method) to ensure the surfactant's performance meets your standards. It is highly recommended to use Made-in-China.com's 'Audited Supplier' reports to verify the manufacturer's production capacity and quality management systems (ISO 9001) before placing a bulk order.

SCI is hygroscopic and sensitive to moisture. It should be stored in a cool, dry, and well-ventilated warehouse in its original hermetically sealed packaging. The standard shelf life is generally 24 months from the date of manufacture. Ensure the supplier uses moisture-proof lining in the packaging (usually 25kg fiber drums or bags) to prevent clumping during sea freight.

The biggest risks include substandard active matter concentration and contamination. Mitigate these by using Trade Assurance services on platforms like Made-in-China.com to protect your payment until the goods are verified. Always arrange for a pre-shipment inspection (PSI) by a third party like SGS or Intertek to confirm the chemical composition matches the agreed specifications.

Prices for SCI are influenced by the cost of coconut oil and ethylene oxide. Negotiate based on tiered volume pricing; orders exceeding 5 metric tons typically qualify for a 10-15% discount. For long-term contracts, request a formula-based pricing model linked to raw material indices. Regarding Incoterms, FOB (Free On Board) is recommended for experienced buyers to maintain control over freight costs, while CIF (Cost, Insurance, and Freight) is better for those who prefer the supplier to handle the logistics risks.

While SCI is generally classified as non-hazardous for transport, you must ensure the HS Code (typically 3402.13 or 3402.42) is correctly declared to avoid customs delays. Provide your customs broker with the SDS and Technical Data Sheet (TDS) in advance. For shipping to the US or Europe, ensure the pallets are ISPM 15 compliant (heat-treated) to prevent quarantine issues at the port of entry.
