The Hansmol GLS anionic surfactants are a series of sodium salts of alkyl naphthalene sulfonic acid formaldehyde condensate. These products provide excellent wetting, dispersing, hydrotroping and medium to low foaming. They offer acid and base stability, hard-water tolerance and high temperature stability. The SNF naphthalene sulfonate–formaldehyde condensates are used primarily as dispersants in a wide variety of industrial applications. If stored properly in its original sealed packaging the shelf life is at least 12 months.

Hansmol GLS is a sodium salt of polymeric naphthalene sulfonate condensates. As a powder, it is a convenient alternative to liquids if your process or storage capabilities are not suitable. As a low molecular weight dispersant with moderate levels of sodium sulfate; it is especially useful in dispersions having low solids content. Because of its economy and versatility, it finds use in many industrial applications. When heated to decomposition it emits toxic fumes of oxide of sulphur and carbon.

Hansmol GLS is used in Textile Oil industry: Functioning as an anti friction agent in oil rigging operation. resistant to alkalis, acids and salts. It is anionic and has good compatibility with other anionic auxiliaries. It is efficient wetting and levelling agent for dyeing pf Acid, Pigment, Direct Chrome, Sulphur & Vat dyes on cotton & wool. Also suitable for uniform dyeing of mixed fabrics. Used as a wetting agent in manufacture of disperse dyes. HANSMOL GLS POWDER is also a versatile emulsifying and stabilizing agent for dispersions including SBR Latex.

Hansmol GLS powder is available in 25 kg HDPE & Paper bag. Alternative packing sizes may be available upon request.
