Applications & Use Cases
- ▸ Used as a hydrotrope in liquid laundry detergents, dishwash liquids, hard-surface and industrial cleaners to solubilize surfactants, reduce viscosity, and keep concentrated formulations clear and phase-stable.
- ▸ Functions as a coupling and clarity agent in alkaline and high-electrolyte cleaning concentrates, preventing cloud-point separation and gel formation during storage and dilution.
- ▸ Serves as a synthesis intermediate and stabilizer in the production of dyes, resins, and pharmaceutical intermediates where the tosylate counter-ion is required.
- ▸ Applied as a viscosity-reducing solubilizer in oilfield and industrial surfactant blends to improve handling and pumpability of concentrated chemistries.
- ▸ Used in personal-care surfactant systems (shampoos, body washes) as a hydrotrope to lower viscosity and improve cold-temperature clarity at appropriate grade and purity.
