Claim 1
Independent Claim
113 words
AN ANHYDROUS, AEROSOL FOAM COMPOSITION USEFUL IN THE TREATMENT OF VAGINITIS CONSISTING OF: A. FROM 0.2 TO 0.5% BY WEIGHT OF CANDICIDIN; B. FROM 2 TO 5% BY WEIGHT OF A NONIONIC, WAXY, FOAMING AGENT PREPARED BY REACTING ETHYLENE OXIDE WITH STEARYL ALCOHOL, HAVING A MELTING RANGE OF 48*-52*C., A MAXIMUM IODINE VALUE OF 3.5 AND A MAXIMUM SAPONIFICATION VALUE OF 14; C.
