sles 70%

When sourcing SLES 70%, you must prioritize the Active Matter content, which should strictly be 70% ± 2%. Other critical parameters include the Unsulfated Matter (less than 2.5%), Sodium Sulfate (less than 1.5%), and pH value (typically 7.0–9.5 in a 10% solution). For high-end personal care products, ensure the 1,4-Dioxane content is below 30ppm (or lower depending on regional regulations) to ensure consumer safety.

The distinction lies primarily in purity and byproduct levels. Cosmetic-grade SLES requires much lower levels of 1,4-Dioxane and inorganic salts to prevent skin irritation and ensure formula stability. Industrial-grade SLES, used in heavy-duty cleaners or construction chemicals, may have higher tolerances for impurities. Always request a COA (Certificate of Analysis) for every batch to confirm the grade matches your application.

SLES 70% is a high-performance anionic surfactant favored for its excellent decontamination, emulsification, and foaming properties. It is the primary ingredient in shampoos, bubble baths, and liquid detergents. Its functional advantages include hard water resistance and high biodegradation rates, making it an economically feasible choice for mass-market cleaning products.

Suppliers should ideally hold ISO 9001 for quality management and ISO 14001 for environmental management. For international trade, ensure the product is REACH registered if exporting to Europe. Additionally, check for Material Safety Data Sheets (MSDS) and Technical Data Sheets (TDS) to ensure the product meets international chemical handling and safety standards.

SLES 70% is a paste-like substance and is typically packed in 170kg or 220kg plastic drums, or IBC tanks (1000kg). It is vital to ensure the drums are UV-resistant and hermetically sealed to prevent moisture absorption or leakage. During transit and storage, the temperature should be maintained between 5°C and 40°C; temperatures below 10°C may cause the product to thicken, requiring specialized heating equipment for unloading.

To ensure transaction security, use Trade Assurance services provided by reputable platforms like Made-in-China.com. Never settle for 100% upfront payment; a standard 30% deposit and 70% against the Bill of Lading (B/L) is common. Furthermore, consider hiring a third-party inspection agency (like SGS or Intertek) to perform a pre-shipment inspection to verify the quantity and quality of the chemical drums.

SLES is classified under HS Code 340231 (or similar depending on local variations). You must check for anti-dumping duties that your country might impose on chemical imports from specific regions. Ensure the supplier provides a GHS-compliant label (Globally Harmonized System) on all packaging, as missing hazard communication labels can lead to customs seizures or heavy fines at the port of entry.

Chemical pricing is highly sensitive to raw material costs (Ethylene Oxide and Fatty Alcohols) and petroleum price fluctuations. To secure better rates, negotiate based on annual volume commitments rather than spot orders. Suppliers on Made-in-China.com are often willing to offer a 5-10% discount for recurring monthly shipments or for orders exceeding full container loads (FCL).
