The invention relates to the use of at least one viscous compound, the viscosity of which is greater than 5 Pa.s-1to substantially prevent the degradation of a substance sensitive to temperatures of 20 °C to 100 °C and/or to pressures of 106 to 107 Pa and/or to a relative humidity of 60% to 100% contained in a powder composition, said powder composition comprising particles with: a core containing said sensitive substance and at least one viscous compounds as impregnating agent for the sensitive substance and a coating for the core, said coating containing at least one viscous compound as immobilising agent. |
