Ufaryl (Thony) P‑85
Ufaryl P‑85 is a high-activity (~85%) linear alkylbenzene sulfonate (LAS) anionic surfactant supplied as a free-flowing powder. It is specifically designed for use in cleaning products, particularly toilet cleaner blocks and powdered detergents. Ufaryl P‑85 provides excellent detergency, foaming, and wetting properties, with good biodegradability. Its balanced particle density makes it ideal for tablet, block, and powder formulations.
Primary Uses
Toilet Cleaner Blocks & Powder Detergents
Acts as the main cleaning and foaming agent, providing effective removal of greasy stains and controlled surfactant release.
Laundry Detergents
Used in powder and tablet detergents to deliver excellent cleaning performance, especially in removing oils and soils.
Hard Surface Cleaning
Incorporated in formulations for floor cleaners and general purpose cleaning powders, enhancing foam stability and cleaning power.
Secondary Uses
Manual Dishwashing Liquids and Car Wash Shampoos
Provides good grease-cutting and foaming properties for manual cleaning applications.
Industrial and Institutional Cleaners
Used in soil-removing formulations for industrial settings, helping disperse dirt and prevent redeposition.
Shampoos and Personal Care Products
Used in low-irritancy formulations for gentle cleansing, particularly in products for sensitive skin.
Liquid Degreasers
Acts as a surfactant to break down oily and bituminous residues in industrial degreasing cleaners.
