micellkoncentrációt

Micellkoncentráció refers to the concentration of surfactant molecules in a solution above which micelles begin to form. Surfactants are amphiphilic molecules, meaning they have both a hydrophilic (water-loving) head and a hydrophobic (water-fearing) tail. In an aqueous solution, below the micellkoncentráció, surfactant molecules tend to adsorb at the air-water interface, reducing surface tension. As the concentration of surfactant increases, the solution becomes saturated with monomers at the interface. Beyond this point, to minimize contact between the hydrophobic tails and water, the surfactant molecules aggregate into spherical structures called micelles. These micelles have their hydrophobic tails oriented inwards, away from the water, and their hydrophilic heads facing outwards, towards the water. The temperature can also influence micelle formation and stability. This phenomenon is crucial in various applications, including detergency, drug delivery, and emulsification, where the ability of micelles to solubilize hydrophobic substances in aqueous media is exploited. The specific micellkoncentráció value is dependent on the type of surfactant, the solvent, temperature, and the presence of other solutes.
