Definitions
- the invention relates to the use of vinyl acetate-sulfonate copolymers as solubilizers of sparingly soluble in water biologically active substances. Furthermore, the invention relates to corresponding preparations for human, animal and plant use and to specific copolymers.
- Solubilization is understood to mean the solubilization of substances which are soluble or insoluble in a particular solvent, in particular water, by surface-active compounds, the solubilizers. Such solublisers are able to convert poorly water-soluble or water-insoluble substances into clear, at most opalescent aqueous solutions, without the chemical structure of these substances undergoing any change (cf. Römpp Chemie Lexikon, 9th edition, Bd.5. P. 4203, Thieme Verlag, Stuttgart, 1992).
- solubilizates prepared are characterized in that the poorly water-soluble or water-insoluble substance is colloidally dissolved in the molecular associates of the surface-active compounds which form in aqueous solution-for example the so-called micelles.
- the resulting solutions are stable single-phase systems that appear optically clear to opalescent and can be prepared without energy input.
- solubilizers can improve the appearance of cosmetic formulations as well as food preparations by rendering the formulations transparent.
- the bioavailability and thus the effect of drugs can be increased by the use of solubilizers.
- solubilizers for pharmaceutical drugs and cosmetic active ingredients surfactants such as ethoxylated (hydrogenated) castor oil, ethoxylated sorbitan fatty acid esters or ethoxylated hydroxystearic acid are mainly used.
- solubilizers described above, used so far show a number of application disadvantages.
