KG 5 is widely used in the textile industry as a high-performance dyeing assistant, particularly for polyester and polyester-blend fabrics. It enhances dye uptake and color fastness under high-temperature dyeing processes, resulting in more vibrant and durable colors. Its formulation improves leveling and reduces dye aggregation, ensuring uniform color distribution across fabric batches.

In addition, KG 5 serves as a dispersing agent in pigment-based inks and coatings, where it stabilizes fine particles and prevents sedimentation. This property makes it valuable in digital printing inks, especially for textiles and ceramics, where consistent dispersion is critical for print quality.

The chemical is also employed in some agrochemical formulations to improve the suspension and delivery of active ingredients in water-based sprays, enhancing the efficacy of pesticides and herbicides. Due to its thermal stability and compatibility with various additives, it is suitable for use in demanding industrial processes.
