At NINGBO INNO PHARMCHEM CO.,LTD., we pride ourselves on the meticulous manufacturing processes that yield our high-quality Sodium Lauryl Ether Sulfate (SLES) 70%. Understanding the production journey is key to appreciating why SLES 70% is a preferred anionic surfactant in numerous industries.

The synthesis of SLES 70% begins with carefully selected raw materials, typically fatty alcohols derived from natural sources such as coconut oil or palm oil, and ethylene oxide. These components are the foundational elements that, through a series of controlled chemical reactions, give SLES its remarkable properties.

The primary stage is ethoxylation, where ethylene oxide molecules are added to the fatty alcohol chain. This process is critical as it directly influences the surfactant's performance characteristics, including its solubility and foaming ability. Following ethoxylation, the resulting ethoxylated fatty alcohol undergoes sulfation. This step introduces a sulfate group, converting the alcohol into an acidic sulfate ester.

The final crucial step is neutralization. The acidic sulfate ester is reacted with a base, typically sodium hydroxide, to form the sodium salt. This neutralization yields the final SLES 70% product, which is a highly effective anionic surfactant. Rigorous quality control measures are implemented at each stage to ensure purity, consistency, and adherence to industry standards. This includes monitoring active matter content, pH, and the levels of impurities like unsulfated matter and sodium sulfate.

The resulting SLES 70% is a viscous paste or liquid, white to yellowish in appearance, with excellent cleaning, emulsifying, and foaming properties. Its biodegradability and low irritation profile make it a responsible choice for formulators. Whether you are looking for a biodegradable SLES for detergent or a key component for advanced personal care, our manufacturing excellence ensures you receive a premium product.

As a dedicated industrial cleaning SLES supplier and a trusted source for SLES anionic surfactant uses, NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering SLES 70% that meets the highest standards of quality and performance, supporting your product development goals.
