What type of emulsion is suntan lotion classified as?

Suntan lotion is classified as an oil-in-water emulsion because it consists of oil droplets dispersed in a continuous water phase. This type of emulsion allows for easy spreading on the skin and provides a lightweight, non-greasy feel. The water component helps in moisturizing the skin, while the oil component helps in creating a protective barrier and can enhance the absorption of UV filters or other beneficial ingredients.

In most suntan lotions, the water phase is the dominant component, which not only aids in application but also helps to prevent the lotion from feeling overly oily or thick, making it more appealing for consumers who seek a comfortable product for sun exposure.
