PROBLEM: To develop a rinse aid for mechanical dishwashing that will minimize water spotting and streaking, you need a surfactant with very low foam, good rinsing and wetting action.

SOLUTION: Pluronic polyols excel in all of these characteristics. In addition they have an extremely low order of toxicity. And rinse aids based on a Pluronic are easily formulated.

Can Pluronic® polyols

PKÜöLEM: -Formulators of home-laundry detergents must eliminate excessive foaming. But i t is often difficult to reduce the foam to the desired level with­out a loss of detergency.

actually increase detergency! Systematic evaluation using the Pluronic Grid will determine the best grade for a specific formula.

PROBLEM: Starch-latex paper coatings require a stabilizer because starch and latex are incompatible. Casein can be used, but it raises the viscosity, must be cooked, can' t be stored.

SOLUTION: When Pluronic L6£ is used in place of casein, it actually reduces the viscosity of the coating! I t requires no preparation, won't deteriorate, and acts as a foam depressant.
