Abstract
Compositions and devices are provided that provide a persistent low-friction coating on a solid surface, by application of a mixture of a polyethylene glycol-containing surfactant and a vegetable to the surface. The coating thus generated does not require replenishing during use and persists through rinsing and multiple uses. Surprisingly, markedly reduced friction is found when the surfactant is provided at 3% w/v to 7% w/v in the composition. Such compositions and methods are suitable for application to both mixing and separation operations. Formulation of such compositions with food grade components permits use in food processing.
