Definitions from the WebMicelleDescriptionA micelle is a small, spherical structure formed by the association of molecules in a liquid, typically consisting of a polar outer shell and a nonpolar inner core. Micelles are formed by the process of micellization, where amphiphilic molecules, such as surfactants or lipids, arrange themselves in a specific way due to their hydrophilic (water-loving) and hydrophobic (water-repelling) properties. Sense 1 (Chemistry)In chemistry, a micelle is a self-assembled aggregate of surfactant molecules dispersed in a liquid solution. These micelles form when the concentration of surfactant reaches a certain critical concentration, called the critical micelle concentration (CMC). Within the micelle, the hydrophobic tails of the surfactant molecules are shielded from the surrounding solvent, while the hydrophilic heads are exposed to the solvent. Example Sentence:Adding dish soap to oil creates micelles that help to disperse the oil in the water, allowing for easier cleaning. Sense 2 (Biology)In cell biology, a micelle refers to a small, lipid-based structure formed by the aggregation of amphiphilic molecules, such as phospholipids, in aqueous environments. These micelles play a crucial role in the absorption, transportation, and metabolism of lipids in living organisms. Example Sentence:The micelles in the small intestine enable the absorption of dietary fats into the bloodstream. Sense 3 (Cosmetics)In the cosmetic industry, micelles are widely used as a key ingredient in micellar water or cleansing solutions. These products contain tiny micelles that act as molecular magnets, attracting and trapping dirt, oil, and other impurities on the skin, leaving it clean and refreshed without the need for rinsing. Example Sentence:She gently wiped her face with a cotton pad soaked in micellar water to remove makeup and cleanse her skin. Related Products on Amazon: | ||||
