Mizellquellung und die Bildung von Solubilisaten, Mikroemulsionen und Emulsionen

Abstract

Solubilizing and emulsifying tests on p-xylene and styrene with the aid of polyglycol ethers show that the swelling of micellar regions is responsible for these processes.

If we dissolve the solubilizer or emulsifier in the aqueous phase, we obtain better results than when dissolving them in the oil phase, since only the micelle structures present in the aqueous phase can solubilize and emulsify. An emulsion is destroyed by the emulsifier changing out of the aqueous into the oil phase.

Through the addition of a related type of alcohol, more organic substance is taken up by systems which are less subjected to mechanical stress, but less organic substance is taken up by systems which are more strongly stressed.

Phase diagrams between polyglycol ethers and water show that lamellar structures are responsible for the swelling of the micelles.
