Elfacos® GT 282 S is easily incorporated into surfactant and non- surfactant systems when working above the melting point (70- 80°C). For ease of incorporation into cold process formulations, it is recommended to prepare a premix of 15% Elfacos® GT 282 S in water and subsequently add mix to the rest of the formulation. The recommended procedure to prepare aqueous solutions of Elfacos® GT 282 S polyalkylene glycol derivative is:

• Heat water or the surfactant solution to about 70-80°C
• AddElfacos® GT 282 S pellets while stirring rapidly
• Cool down with continued stirring
• During cooling, the mixture becomes clear at about 40°C (below cloud point on heating) and the viscosity increases.

Elfacos GT 282S nonionic copolymer exhibits exceptional clarity in aqueous systems.

Synergistic Thickening

Elfacos® GT 282 S nonionic copolymer exhibits excellent synergistic effect with most anionic and amphoteric surfactants.

Synergistic Thickening with salt

Low levels of Elfacos® GT 282 S nonionic copolymer synergistically boost viscosity with salt.

The molecular structure of Elfacos® GT 282 S consists of three parts, where the central hydrophilic moiety is linked at both ends to lipophilic chains via hydrolytically stable ether bonds. This makes Elfacos® GT 282 S inherently resistant against hydrolysis, even at elevated temperatures and over a wide pH range.

Keep container tightly closed. Store in a cool, well-ventilated area.
