| description | A water dispersible colloidal system in the form of generally spherical matr ix type particles and of sizes typically in the range of from 50 to 500 nm, called nanoparticles, and a process for the preparation of such systems. The system is characterized in that the nanoparticles comprise at least one amphiphilically modified calixarene. The water dispersion contains at least one active component such as a cosmetic, a pharmaceutical compound or other biologically active substances, foods, beverages, etc. enclosed within the nanoparticles, in the outer aqueous phase, or in both. The systems show outstanding properties, especially long-life stability even at elevated la temperatures. |
