Salvatore Joseph DeSalva has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 3963833
    Abstract: The development of perspiration is inhibited by topical application of 3-phenyl-3-carbo-(beta-di-lower alkylamino)-lower alkoxy-2,3-dihydrobenzofuran or a salt thereof, preferably the hydrochloride, and an antiperspirant aluminum, zinc, or zirconium salt, preferably aluminum chlorohydrate or aluminum chloride. The compositions applied may be aqueous, preferably including a surface active agent, such as a nonionic synthetic surface active compound of poly-lower alkylene oxide, or they may be non-aqueous, as in "aerosol" powder sprays. The amounts of the composition employed are small and the proportion of antiperspirant metal salt present is greater than that of the dihydrobenzofuran compound.

  • Patent number: 3953590
    Abstract: A method for inhibiting perspiration comprises applying to a site at which perspiration is normally exuded, an antiperspirant of the formula ##SPC1##Or a salt thereof. In preferred compounds, A, B, D, E, and G are hydrogen and R is phenyl, alkyl, hydroxyalkyl, aminoalkyl, alkenyl or oxopyridyl. Also useful are the corresponding hydrohalic acid salts. The compounds are preferably applied to the human axillae as aqueous antiperspirant compositions containing a surface active agent. Some of the S-substituted benzothiohydroximic acids and hydrohalic acid salts are new compounds of especially good antiperspirant activities, e.g., those in which the R group is linear alkyl of 6 to 9 carbon atoms, lower aminoalkyl, lower hydroxyalkyl, 1-oxopyridyl, and the hydrochloric acid salts of the compounds in which R is lower aminoalkyl.
