摘要：
The present invention relates to biocide zinc oxide microparticles, preparation method and use thereof. More particularly, the present invention relates to zinc oxide microparticles comprising platelets, wherein the platelets are prisms with hexagonal type base, have an edge length less between 30 nm and 200 nm, are stacked in direct contact with each other along the stacking c-axis by means of their [0001̅] or [0001] crystalline planes, and are rotated by a non-zero angle with respect to their adjacent platelets along said stacking c-axis, wherein said zinc oxide microparticles are characterised by a specific surface area which is less than or equal to 4 m2/g. The invention also relates to a method for preparing the zinc oxide microparticles of the invention. The invention further relates to a cosmetic product, paint, ink, paper, cardboard, textile, food, agricultural, home care, air conditioning, animal care, personal and work hygiene, contact lens, chromatography material, medical equipment, dermatological, lacquer, coating and/or plastic product containing the zinc oxide microparticles of the invention and to a biocide composition comprising the zinc oxide microparticles as defined above. Finally, the invention further relates to the use of the biocide composition of the invention for the elimination, inhibition of the growth, or inhibition of progeny of microorganisms and to the zinc oxide microparticles of the invention or pharmaceutical composition comprising them for use in the treatment or prevention of an infection.La présente invention concerne des microparticules d'oxyde de zinc biocides, leur procédé de préparation et leur utilisation.
