The invention relates to (dried) capsules with a high active-ingredient or active-substance content, to the use of the capsules in cosmetic and/or pharmaceutical compositions and to the production of the capsules.

Capsules with a high active ingredient content

Active ingredient capsules are proposed which are obtainable by, with the input of mechanical and thermal energy, (a) dissolving and/or dispersing proteins, polysaccharides and cellulose derivatives in water, (b) adding the active ingredients to be encapsulated, (c) hardening the resulting coacervates with the addition of tannins and optionally (d) then subjecting them to a spray drying.

Active ingredient capsules

Spherical capsule having a liquid core and a seamless solid shell surrounding the core, in which: the diameter of the capsule is in the range of 4-8 mm; the thickness of the shell is in the range of 20-200 &#x3bc;m; the shell thickness to capsule diameter ratio is in the range of 0.004-0.04; the shell contains 70-90% (m/m) gelatin and 10-30% (m/m) plasticizer, based on the solids content of the shell; and the core has a flavoring content in the range of 1-100% (m/m), based on the total mass of the core.

Seamless filled capsules
