Impregnated powder improving bioavailability and/or solubility and method of production
First Claim
1. An impregnated powder for increasing the bioavailability and/or the solubility of at least one active principle comprising a solid inert support, in a particle form impregnated by a liquid medium comprising a hydrophobic phase and a hydrophilic phase, at least one surfactant and at least one active principle wherein said active principle(s) is (are) dissolved in one of said hydrophilic or hydrophobic phases, and in the form of a suspension in the other one of said phases, wherein the phase in which the active principle(s) is (are) dissolved is an active principle saturated solution.

Abstract
This invention relates to an impregnated powder for increasing the bioavailabilty and/or the solubility of at least one active principle comprising a solid, inert support in a particle form impregnated by a liquid medium comprising a hydrophobic phase and optionally a hydrophilic phase, at least one surfactant and at least one active principle dissolved in at least one of said phases, wherein said active principle(s) is(are) also present in at least one of said phases in the form of a suspension.
Such an impregnated powder is used as a base for various preparations in the pharmaceutical, parapharmaceutical and cosmetic field, in the food complement field and in the food processing industry.
