Supragil MNS/88-E is a condensed methyl naphthalene sulfonate, sodium salt.
Dispersing agent for wettable powders, concentrated suspensions and water dispersible granules, binding properties.
Particularly suitable for high concentration water dispersible granules.
From a chemical standpoint, Supragil MNS/88-E belongs to the alkyl or methyl naphthalene sulfonate family, which combines an aromatic hydrophobic structure with a highly polar sulfonate group.
This structure enables strong adsorption onto particle surfaces while maintaining excellent water solubility.
As a result, it effectively lowers interfacial tension and promotes rapid wetting of powders and pigments.
Functionally, Supragil MNS/88-E works by imparting a negative surface charge to dispersed particles, creating electrostatic repulsion that prevents agglomeration and settling.
Supragil MNS/88-E remains stable over a wide pH range and performs reliably in the presence of electrolytes and hard water.
These characteristics make it suitable for demanding formulation environments where long-term dispersion stability and processing robustness are essential.
Supragil MNS/88-E is a proprietary, high-performance anionic dispersing agent formulated on methylnaphthalene sulfonate sodium salt chemistry.
It is engineered to enhance the wetting, dispersion, and stabilization of poorly soluble solids in aqueous systems, particularly in formulations that require fine and uniform particle distribution.
The product is intended for industrial and professional use, where reliability and reproducibility are critical.
At the molecular level, Supragil MNS/88-E features an aromatic naphthalene backbone that provides strong hydrophobic interactions with solid particle surfaces, combined with a sulfonate group that ensures high water solubility.
This amphiphilic structure allows the dispersant to anchor onto particles while remaining well-dispersed in the aqueous phase.
As a result, it significantly reduces surface tension and accelerates the wetting of powders and pigments.
Mechanistically, Supragil MNS/88-E stabilizes dispersions by adsorbing onto particle surfaces and imparting a strong negative charge.
This electrostatic repulsion minimizes particle–particle attraction, thereby preventing flocculation, agglomeration, and sedimentation over time.
The dispersion remains homogeneous even during long-term storage or under mechanical stress such as pumping and mixing.
Supragil MNS/88-E exhibits excellent chemical stability across a broad pH range and maintains its dispersing efficiency in electrolyte-rich or hard water systems.
It also shows good thermal stability and resistance to hydrolysis, allowing it to withstand typical industrial processing conditions.
These properties make it compatible with high-shear mixing, milling, and other demanding formulation processes.
Supragil MNS/88-E is valued for its strong dispersing power, formulation robustness, and versatility.
It is particularly suitable for applications in agrochemicals, pigments, dyes, construction chemicals, detergents, and other specialty chemical formulations where consistent dispersion quality and long shelf life are essential.
Supragil MNS/88-E is a specialty anionic surfactant and dispersing agent developed for high-demand aqueous formulations that require reliable and long-lasting dispersion of hydrophobic solids.
It is typically supplied as a sodium salt based on methylnaphthalene sulfonate chemistry, which provides a strong balance between hydrophobic interaction and hydrophilic solubility.
This balance allows the product to perform efficiently at relatively low use levels.
Structurally, the aromatic naphthalene core of Supragil MNS/88-E enables strong adsorption onto pigment, filler, or active ingredient surfaces, while the sulfonate group ensures excellent compatibility with water.
This dual functionality enhances interfacial activity and facilitates rapid wetting of powders that would otherwise be difficult to disperse.
As a result, dispersion processes become faster and more energy-efficient.
From a formulation perspective, Supragil MNS/88-E provides electrostatic stabilization by creating a negatively charged layer around particles.
This repulsive force prevents particle aggregation and sedimentation, maintaining a uniform and stable dispersion over extended storage periods.
The product performs consistently even under mechanical stress such as agitation, pumping, or high-shear mixing.
The dispersant shows strong tolerance to a wide pH range and remains effective in systems containing electrolytes, salts, or hard water ions.
Its chemical and thermal stability allow it to be used in a variety of industrial environments without significant degradation.
These characteristics are particularly valuable in complex formulations where other surfactants may lose effectiveness.
Supragil MNS/88-E is recognized as a robust and versatile dispersant suitable for industrial, agrochemical, pigment, dye, detergent, and specialty chemical applications.
