Sodium lauryl sulfate sls k12

When purchasing SLS K12, you must prioritize the Active Matter content, which typically ranges from 92% to 95% for needle or powder forms. Ensure the pH value is maintained between 7.5 and 10.5 in a 1% aqueous solution to guarantee stability. Additionally, monitor the Unsulfated Matter (Free Oil) levels, which should be below 1.5% to ensure high purity and prevent interference with foaming properties. For liquid applications, the color (APHA) should be as low as possible to avoid affecting the final product's appearance.

SLS K12 is a versatile anionic surfactant used extensively in Personal Care (shampoos, toothpastes, and bubble baths) due to its excellent emulsifying and foaming properties. In the Industrial sector, it serves as a wetting agent in textile processing and an emulsifier in polymerization processes (like PVC production). It is also a critical component in Household Cleaning products, such as laundry detergents and dishwashing liquids, where high-performance grease removal is required.

Suppliers must provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For exports to the EU, REACH registration is mandatory. If the product is intended for cosmetics or pharmaceuticals, ensure the supplier adheres to GMP (Good Manufacturing Practice) standards. Furthermore, check for ISO 9001:2015 certification to ensure consistent quality management systems are in place.

SLS K12 is available in Powder, Needle, and Granular forms. Powder offers the fastest dissolution rate but poses a dust inhalation risk, requiring specialized ventilation. Needle and Granular forms are preferred for large-scale manufacturing as they are low-dust, easier to handle, and reduce material loss during the charging process. Choose the form that aligns with your factory's Health, Safety, and Environment (HSE) protocols and mixing equipment capabilities.

The main risks include quality inconsistency and moisture absorption during transit. To mitigate these, use Trade Assurance services on Made-in-China.com to protect your payment until the goods are verified. Always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek to verify the Active Matter percentage and packaging integrity before the balance payment is made.

SLS K12 is sensitive to moisture; therefore, it should be packed in multi-layer paper bags or woven bags with a PE inner liner, typically 20kg or 25kg per bag. For sea freight, ensure the containers are dry and clean, and request pallets with shrink-wrap to prevent bag breakage. Since it is classified as a chemical, ensure the supplier provides the correct HS Code (typically 3402.31) and complies with IMO (International Maritime Organization) regulations if classified as hazardous in specific concentrations.

Pricing for SLS K12 is highly sensitive to raw material costs (Lauryl Alcohol) and petroleum price fluctuations. Negotiate based on volume tiers; for example, a full container load (FCL) usually yields a 5-10% discount compared to LCL. For long-term cooperation, seek formula stability guarantees rather than just the lowest price, as frequent supplier changes can force you to reformulate your end products, incurring higher R&D costs.

Always verify the supplier's Business License and Export Permit for Chemicals. Conduct all communications and payments through the Made-in-China.com secured platform to maintain a legal paper trail. Avoid suppliers who insist on private bank account transfers or Western Union. Ensure the Proforma Invoice (PI) clearly states the technical specifications, lead time, and compensation terms for sub-standard quality.
