Lanolin alcohol contains cholesterol and derivatives producing which emulsion type?

Explanation:
The main idea is that the type of emulsion depends on how the emulsifying components interact with water versus oil. Cholesterol and its derivatives in lanolin alcohol are highly lipophilic, so they favor stabilizing droplets of water dispersed within the oil phase. This creates a water-in-oil emulsion, where oil is the continuous phase and water exists as dispersed droplets. The greasy, occlusive feel of lanolin-based preparations is characteristic of this W/O type. Gel or suspension aren’t emulsions and don’t reflect the role of these lipophilic cholesterol derivatives in forming an oil-continuous system.
