Ether sulfate

When purchasing Ether Sulfate (SLES), the most critical specification is the Active Matter content, typically available in 70% (paste) or 28% (liquid) concentrations. You must also verify the Unsulfated Matter (<2.5%), Sodium Sulfate content (<1.5%), and pH value (7.0–9.5). For high-end personal care products, ensure the 1,4-Dioxane content is strictly controlled (typically <10ppm or <30ppm) to meet safety standards.

Ether Sulfate is a versatile anionic surfactant used extensively in the detergent and cosmetic industries. It is the primary ingredient in shampoos, bubble baths, and shower gels due to its excellent foaming and emulsifying properties. In industrial sectors, it is used in textile wetting agents, fire-fighting foams, and construction chemicals for its superior hard-water resistance and biodegradability.

Suppliers should provide a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (COA) for every batch. For export to the EU, REACH registration is mandatory. If the product is intended for cosmetics, compliance with ISO 22716 (GMP for Cosmetics) is highly recommended. Ensure the packaging complies with UN-rated standards for chemical transport to prevent leakage.

Request a pre-shipment sample to test for color (Hazen/APHA)—it should be clear to slightly yellowish with no distinct odor. Evaluate the viscosity stability when diluted. Professional suppliers on Made-in-China.com often hold ISO 9001 certifications, which indicates a standardized quality management system for chemical production.

The main risks include concentration degradation due to improper storage and leakage during transit. SLES 70% is highly viscous and can be difficult to unload if temperatures drop significantly. Always confirm the packaging integrity (plastic drums or IBC tanks) and ensure the supplier uses moisture-proof lining for bulk shipments.

Prices for Ether Sulfate are heavily influenced by the cost of raw materials like Ethylene Oxide and Fatty Alcohols. It is wise to negotiate formula-based pricing for long-term contracts. For MOQs, while standard is often one 20ft container (approx. 17.6 - 20 tons), you can negotiate smaller trial orders by highlighting potential annual procurement volume.

SLES is generally classified as non-hazardous for transport, but it must be kept away from strong oxidizers and acidic materials. Ensure the shipping containers are clean and free of contaminants. For 70% concentration, specify flexitanks or reinforced drums to optimize freight costs while maintaining product stability during long-haul sea freight.

Utilize the Secured Trading services provided by Made-in-China.com to protect your payment until the goods are shipped. Conduct a third-party factory audit (such as SGS or Intertek) to verify the supplier's production capacity and environmental compliance, ensuring they are a legitimate manufacturer rather than a small-scale middleman.
