Dow Corning Offers GP 4503 Powdered Antifoam for Automatic Dishwashing Detergents

A breakthrough in antifoam technology from Dow Corning allows automatic dishwashing detergents to be formulated with surfactants that improve cleaning performance. The new technology may also help lower energy consumption.

Dow Corning® GP 4503 Powdered Antifoam enables formulation of detergents with foaming surfactants known for their excellent cleaning, but which could not be used in automatic dishwashing applications. Under current operating conditions, the surfactants produce significant amounts of foam, which can impact the efficiency of the cleaning mechanism.

“Until now, there hasn’t been an effective way to control foam levels,” said Yan Cortes, Dow Corning Household Care global marketing manager. “Surfactants that produce excessive foam slow the rotation of spray arms and reduce cleaning and spraying efficiency. The new antifoam solves that problem.”

Dow Corning® GP 4503 Powdered Antifoam is formulated with a water-soluble carrier to limit residue on dishes and dishwasher parts. It was developed to perform in extreme conditions, especially under high pH and high agitation, which typically generate excessive foam. The new silicone antifoam provides effective foam control throughout the entire dishwashing cycle with no noticeable buildup on dishes.

The silicone antifoam is easy to incorporate into detergent tablets and powders. Free-flowing, noncaking white granules simplify mixing, and they do not collect in the matrix of the detergent structure.

Automatic dishwashing tablets are the largest and fastest growing segment among automatic dishwashing products, and consumers appreciate their convenience compared to liquids and powders. As automatic dishwashers become affordable to more consumers, the market for effective cleaning products will continue to grow.

“The availability of an adequate foam control product opens new perspectives for automatic dishwashing formulators,” said Cortes. “Products can be developed for use at lower wash temperatures, with a possible reduction in energy consumption, as well as use of milder detergent components.”
