Effect of non-ionic surfactants on imbibition of porous structures with emulsions
Three com. emulsifiers were used (1-5% by vol.) for dispersing a corn. vegetable oil in water to produce resp. emulsions (oil content 10-30% by vol.) used for imbibitions a polypropylene nonwoven (porosity 0.93). The ethoxylated oleic acid-based emulsifier was the most efficient due to providing the highest amts. of the dispersed phase in a sorbent. For 10% emulsions, the largest mass of the imbibed permeant was observed in case of alkoxylated alc.-based emulsifier.
