USE OF BIS(DICARBOXYLIC ACID) DIAMINOALKYLENE DERIVATIVES AS BIOLOGICALLY DEGRADABLE COMPLEXING AGENTS FOR ALKALINE EARTH METAL IONS AND HEAVY METAL IONS

摘要

Disclosed is an active substance composition, specially a cosmetic agent, a light-screening agent or a vitamin composition, containing one or several compounds of formula (I), specially an active substance composition, containing as a compound of formula (I) ethylene diaminosuccinate (EDDS), ethylene diaminoglutamate (EDDG) or (2-hydroxy propylene)-1,3-diaminosuccinate (HPDDS). The invention also relates to the use of bis(dicarboxylic acid) diaminoalkylene derivatives of the above formula (I) as complexing agents for earth alkaline metal ions and heavy metal ions in active substance compositions, specially cosmetic agents, screening agents, vitamin compositions and for stabilizing oxidation-sensitive active substances.
