Features/benefits
Improved detergent aspect
Tinopal Rx significantly improves the shade consistency and white appearance of detergents such as conventional and compact powders, soaps, liquid detergents and softeners.
High whiteness delivery
Tinopal Rx yields intense white effects on cellulosic fibers over the whole emperature range, i. e. from cold to hot washings.
Excellent cold wash performance
Tinopal Rx incorporated in detergents is highly soluble in water at low temperatures and yields therefore high white effects even at low washing temperatures and short washing times.
Very good leveling properties
Due to its good solubility, Tinopal Rx demonstrates very good leveling properties: This is an important factor with compact powders and direct dosing.
Improved stability
Tinopal Rx is stable against bleaching agents such as hypochlorite and peroxide and also to alkali, acids and perspiration.
Improved light fastness
Tinopal Rx exhibits very good wet and dry light fastness. Ensures whiteness consistency even when washing is dried outside.
Low spotting
Due to its good leveling properties Tinopal Rx is a low spotting FWA. A critical factor for compact and liquid detergents.
Shade consistency
Even on repeated washing Tinopal Rx delivers an intense whiteness on cellulosic fibers without greening. In other words, white stays whiter longer.
Easy dosing
Tinopal Rx consists of free flowing granules that facilitate dosing during detergent manufacturing and maintains plant cleanliness due to very low dusting.
| Physical form | : Medium fine, free-flowing, no-dusting, non friable granules |
| Color | : Yellowish |
| Active content | : 90% ± 3% |
| UV/Vis Absorbance | : 1143 ± 38 (1% dilution, 1 cm, dist. Water, 349 nm) |
