摘要

The present invention relates to balanced hydrophobic/hydrophilic liquid formulations comprising: (a) between about 10 and about 90 % by weight of an alcohol alkoxylate having formula (I), (b) between about 90 and about 10 % by weight of polypropylene glycol having formula (II), and (c) between about 0.3 and about 10 % by weight hydrophobic silica based on (a) + (b). The invention also pertains to the use of the above mixture in foamed liquids or liquid susceptible to foaming.
