ADJUSTABLE SOL-GEL-BASED CAPSULES COMPRISING FRAGRANCES AND AROMAS, AND USES THEREOF

摘要

The present invention provides compositions comprising fragrance-carrying sol-gel micro-capsules, particularly useful in many fields of industry. The present invention relates generally to controlling the release kinetic profiles of multiple fragrances and aromas through the encapsulation of one or more fragrant mixtures in metal oxides and semi-metal oxide-based micro-particles, and the use of the resulting solid particles in applications where specific component-selective adjustable controlled release of the fragrance or aroma actives is required, either to preserve the original sensory feeling, or to create new ones by changing the classical order of release of top notes, medium notes and bottom notes. The invention also relates to a method for formulating fragrances in water instead than in ethanol while diminishing the harmful interaction between the entrapped fragrance molecules and the skin.
