Product Application
  • Household, Industrial, and Institutional Cleaners: Neutralized Calsoft® LAS-99 is high foaming with excellent detergency and cleaning performance for both greasy and particulate soils. It is an efficient choice surfactant for laundry, manual dish wash, car wash, kitchen, bath, and all-purpose cleaner, heavy-duty cleaner/degreaser formulas.
  • Oil Treatment Intermediates: Calsoft® LAS-99’s high activity, low free oil, and low sulfuric acid makes it the linear sulfonic acid of choice as a starting intermediate for oil treatment compounds. Calsoft® LAS-99 reacts with alkyl amines to produce sulfonates soluble in oil and many non-aqueous solvents.
  • Metal-Treating Baths: Calsoft® LAS-99 is a strong organic acid surfactant that is compatible with mineral acids and organic acids used for metal cleaning and pickling acids. At 0.5% or less of total solution weight promotes rapid grease and oil film removal, superior surface wetting, and complete film-free, residue-free rinsability.
