DSS


DESCRIPTION

Dextran Sulfate Sodium (DSS), also known as Sodium Dextran Sulfate (SDS) is anionic polymer with high molecular weight. Starting with cane sugar, Dextran is synthesized with enzymatic method along with ultra-filtration and nano-membrane system, which has various molecular weights and high purity. Through advanced esterification and sulphonation technologies, top-quality Dextran Sulfate Sodium with 17%-20% sulfur content is acheived. We can supply DSS with different molecular weights, including Mw~500,000, Mw~200,000, Mw~70,000, Mw~40,000, Mw~10,000 Mw~5,000, Mw~3,000 and Mw~1,000 based on years of experiences on R&D and manufacturing. DSS with various sulfur contents and other esterified polysaccharides are also supplied, like Pensotan Polysulfate, β-Glucan Sulfate Sodium. DSS is widely used in pharmaceuticals and cosmetics based on its versatile properties.

ADVANTAGES

² Food-grade cane sugar as raw material - safe and reliable

² Synthesized with enzymatic method - less branches, high purity and activity

² Various molecular weights – tailor-making service

² Very narrow molecular distribution - stable physical and chemical properties, outstanding efficiency

² Various molecular weight Dextran products – enzymatic hydrolysis and nano-membrane filtration system

² Advanced esterization technology - high sulfur content and good stability

² Nano-membrane purification - fewer solvent residues

² Multistage purification process - high purity and safety
