SOKALAN HP 165
SOKALAN HP 165
SOKALAN HP 165 is a spray-dried colorless powder of polyvinylpyrrolidone.
SOKALAN HP 165 is excellent for use as anti-redeposition agent and anti-dye transfer additive.
Appearance SOKALAN HP 165 is an aqueous solution.
Sokalan HP types (water-soluble homo- and copolymers of vinylpyrrolidone, vinylimidazole and nonionic monomers)
The Sokalan HP range is particularly effective in preventing reactive and direct dyes from being transferred on clean fabrics by forming polymer/dye associates in the wash liquor.
SOKALAN HP 165 is an aqueous solution of a modified polycarboxylate that can be used as a polymeric additive in liquid detergents.

SOKALAN HP 165 is a unique polymer that is an 80% active ethoxylated polyethyleneimine or PEI + EO.
SOKALAN HP 165s excellent performance profile allows the reduction of anionic surfactants in liquid laundry detergent without compromising primary and secondary detergency and maintaining overall performance.
SOKALAN HP 165 provides formulators the opportunity to optimize high-concentration formulations for cost/performance benefits and include improved efficacy and stain-fighting claims because:
Prevents redeposition of soil during laundering, even at low temperatures, ensuring clean laundry with low energy consumption
Prevents graying in clothes and enhances the removal of persistent fruit, grass, and clay stains.
SOKALAN HP 165 is effective on difficult stains especially particulates, and can be used as a stain booster for certain bleachable and particulate soils.
Easy to formulate in standard/concentrated liquid laundry detergent formulations and liquid dose packaging
Good compatibility with standard surfactants matrix in liquid laundry detergents.
Readily formulated, even as a drop-in additive, with no negative effects on stability
SOKALAN HP 165 results in 50% reduction in dissolution time at 75% actives and the polymer allow better/even distribution of detergent into cold water, rather than clumping.
SOKALAN HP 165 allows formulators to increase the actives (decrease the dose size), eliminate costly solvents (PG, glycerol), and add a higher performance polymer that can also contribute to antiredeposition and oxidizable soil removal.
Although SOKALAN HP 165 is specially designed for use in liquid laundry detergents, a project was chartered to develop premium performance LDLs utilizing SOKALAN HP 165 as a foam stabilizer & performance booster.
Handling
a) SOKALAN HP 165 should be stored in a dry place in its original sealed packaging.
b)SOKALAN HP 165 is advised to tightly seal every opened container, if they were only partly emptied.
c) Storage temperature above 25 °C will cause an increase of the color number.
d) Please refer to the latest Safety Data Sheet for detailed information on product safety.
