(FR) COQUES D’EXINE
Abstract
(EN)
A whitened exine shell having a degree of whiteness (L*) of greater than 65 measured under D 65 illumination. The shell can be used as a delivery vehicle for an active substance, or as an antioxidant. It can be used in a method of surgery, therapy or diagnosis. The invention provides a formulation containing the whitened exine shell together with an active substance; and a method for preparing the shell by isolating an exine shell from a naturally occurring spore under treatment conditions which do not include aceto lysis, and treating the isolated shell or a precursor thereof with a bleaching composition.
(FR)

La coque peut être utilisée comme véhicule d’administration d’une substance active, ou comme antioxydant. L’invention peut être utilisée dans une méthode chirurgicale, thérapeutique ou diagnostique. L’invention concerne une formule contenant la coque blanchie d’exine ainsi qu’une substance active; et une méthode de préparation de la coque en isolant une coque d’exine à partir dune spore présente à l’état naturel dans des conditions de traitement qui ne comprennent pas l’acétolyse, et en traitant la coque isolée ou son précurseur avec une composition de blanchiment.
