How Surfactants Clean Skin: Micelle Formation Explained #3273113 (License: Personal Use)

This schematic illustrates the mechanism of surfactant action on skin: individual surfactant molecules aggregate in water to form micelles, whose hydrophobic cores encapsulate oily dirt particles, while their hydrophilic exteriors remain soluble. The diagram shows free surfactants, micelles containing trapped dirt, and the skin surface with embedded lipid structures, highlighting the emulsification process critical to cleansing. This molecular behavior underpins the efficacy of soaps, shampoos, and facial cleansers.

Used in dermatology, cosmetic science, and chemistry education web pages to explain cleansing mechanisms; matches user intent for understanding how cleansers work at a molecular level or selecting products based on surfactant technology.
