Which cleanser is described as an oil-in-water emulsion?

• A. Facial Cleansing Lotion
• B. Facial Foaming Cleansers
• C. Witch Hazel
• D. Facial Cleansing Milks

Answer: (D)

Oil-in-water emulsions have tiny oil droplets dispersed in a water-based phase, giving a milky, creamy texture. Cleansing milks are formulated this way, combining a light oil with water and gentle emulsifiers so the product feels smooth on the skin and can lift makeup and grime. When you massage and rinse, the emulsion breaks and the oil droplets rinse away with water, leaving the skin clean without a heavy residue. This is why cleansing milks are described as oil-in-water emulsions.

In contrast, a facial foaming cleanser relies on surfactants to create foam and is typically more water-based with less oil; witch hazel is a water-based solution (often alcohol-containing) without an oil phase; cleansing lotions can be emulsions but their texture doesn't specify an oil-in-water milky dispersion as clearly.
