Abstract
The invention relates to a novel galenical system for taste masking, protecting an active substance, in particular in an acid medium, modulating releasing properties, masking mucous irritability and toxicity of certain active substances, for preparing aqueous forms which have a masked taste, are stable and pH independent. Said invention also relates, in particular to a galenical system which is embodied in the form of lipidic solid particles and strictly hydrophobic and devoid of water, surface active agents, emulsifiers, solvent traces and which is characterized in that it comprises at least one type of hydrophobic wax and at least one type of fatty non-neutralized acid.
