Abstract

Abstract Non aqueous sporicidal and sterilizing compositions for the treatment of inanimates and animate surfaces by means of fluoro or perfluoro carbon agents containing monoaldehydes or saturated dialdehydes with 2 to 8 carbon atoms. Said compositions can be used both for liquid or vapour phase processing. Liquid phase treatment exhibits an increased biocidal activity when combined with ultrasonic irradiation. Therapeutic uses of the new compositions are also described.
