The use of cellulose nanofibrils (CNF) in different applications has grown exponentially since this nanomaterial was first isolated more than 30 years ago. The incorporation of CNF in emulsified systems is a subject that has received limited attention but has a great potential given CNF ability to stabilize interfaces. Here we investigated the effect of incorporating CNF in emulsified systems. Soybean oil was used as the organic phase and water-in-oil (W/O) microemulsions and normal emulsions were prepared containing CNF in the aqueous phase. Also, multiple emulsions of the water-in-oil-in-water (W/O/W) type were obtained when the composition of the system was changed. The emulsions obtained were analyzed and characterized using different techniques. The presence of CNF in the aqueous phase enhanced the stability of the W/O/W emulsion, especially at high concentrations of the nanomaterial
