Lipophilic emulsifiers have HLB range and produce what type of emulsion?

Explanation:
Lipophilic emulsifiers have a low HLB, meaning they are more oil-loving. This makes them position at the oil–water interface in a way that stabilizes droplets of water dispersed in the oil phase. So, a low HLB emulsifier is best at forming water-in-oil emulsions. In contrast, higher HLB (more hydrophilic) emulsifiers favor oil droplets dispersed in water. Therefore, the correct pairing is low HLB values producing a water-in-oil emulsion.
