Micellar solution

From Wikipedia, the free encyclopedia
(Redirected from Micellar solutions)
Schematic of a micellar solution showing spherical micelles distributed in water (solvent) and having no long-range positional order.

A micellar solution consists of a dispersion of micelles in a solvent (most usually water). Micelles consist of aggregated amphiphiles, and in a micellar solution these are in equilibrium with free, unaggregated amphiphiles. Micellar solutions form when the concentration of amphiphile exceeds the critical micellar concentration (CMC) or critical aggregation concentration - CAC, and persist until the amphiphile concentration becomes sufficiently high to form a lyotropic liquid crystal phase.[1][2][3][4]

Although micelles are often depicted as being spherical, they can be cylindrical or oblate depending on the chemical structure of the amphiphile. Micellar solutions are isotropic phases.

History[edit]

Micellar originates from France, with its usage in skincare dating back to 1913.[5] Its popularity boomed internationally when French pharmaceutical company Bioderma released their product Sensibio H2O micellar water in 1991, which is said to be sold every 2 seconds worldwide today.[6]

Commercial uses[edit]

Micellar water is used to remove makeup and oil from the face.[7][8][9][10][11]
