Akypo RSPE 66

AKYPO[R] RSPE 66 is a propoxylated and ethoxylated ether carboxylic acid (PO-EO) that exhibits strong performance similar to the conventional AKYPO[R] types in the areas of emulsification and hard water stability. In contrast, however, the PO-EO surfactant outperforms traditional AKYPO[R] types when it comes to foam height and time to foam collapse in laboratory testing.  The reduction in foam height and time to foam collapse can also be observed when the PO-EO surfactants are used in combination with the conventional AKYPO[R] types.
