High fluorescence intensity with excellent blue-toned brightness enhancement for superior whiteness perception.
Outstanding lightfastness and thermal stability, maintaining performance during high-temperature processing (e.g., drying, curing).
Good solubility in water and compatibility with anionic and nonionic surfactants commonly used in detergent and textile formulations.
Low volatility and minimal migration, ensuring long-term whitening effect on treated substrates.
Compliant with major global regulatory frameworks including REACH and meets Oeko-Tex® Standard 100 Class I–IV requirements.
Laundry detergents (powder, liquid, and compact formulations) for cotton, polyester, and blended fabrics.
Textile finishing baths for cotton, viscose, and lyocell to enhance brightness and visual whiteness.
Paper coating and surface sizing applications to improve brightness and opacity of fine papers and packaging boards.
Plastic masterbatches for polyolefins (PP, PE) and PET where heat-stable, non-migrating whitening is required.
Household and industrial cleaning products requiring optical brightening without yellowing or fluorescence quenching.
