The invention relates to a method for producing an active ingredient concentrate from micellar nanoparticles without using chemical aids to absorb fat- or water-soluble active ingredients. The invention further relates to the use of said micellar active ingredient concentrate, in particular on the basis of naturally occurring active ingredients. According to the invention, a fat-soluble active ingredient suspension is produced, which has micelles having a micelle size of up to 1000 nm, the micelles of the active ingredient suspension are comminuted by applying high-pressure, and the micelles are separated from the fat-soluble active ingredient suspension by means of ultracentrifugation. The invention further relates to the use of said micellar active ingredient concentrates and to the composition of the active ingredient suspension of individual method steps.
