Abstract: Quaternary ammonium salts and benzyl mercaptans of amino derivatives of mercaptopyridine-1-oxide, including 1-acylamino- and 2-alkoxycarbonylamino-6-pyridine-1-oxide, having particular utility as antimicrobial agents per se and in skin cleansing detergent compositions, shampoos, hair dressings, disinfectants, preservatives and the like.

Abstract: Novel unsymmetrical disulfides of pyridine-1-oxide and acid addition salts thereof, having particular utility as antimicrobial agents per se and in skin cleansing detergent compositions, shampoos, hair dressings, disinfectants, preservatives and the like.

Abstract: Novel amino derivatives of mercaptopyridine-1-oxide inclusive of 2-acylamino- and 2-alkoxycarbonylamino-6-mercaptopyridine-1-oxides, disulfides thereof, and metal salts thereof having particular utility as antimicrobial agents per se and in skin cleansing detergent compositions, shampoos, hair dressings, disinfectants, preservatives and the like.

Abstract: 2-MERCAPTOQUINOXALINE-1-OXIDES, SALTS THEREOF AND 2-(1-OXOQUINOXALINYL) DISULFIDES ARE USEFUL ANTIMICROBIAL AGENTS, ACTIVE AGAINST GRAM-NEGATIVE AND GRAM-POSITIVE BACTERIA AND FUNGI, E.Q., Escherichia coli, Bacillus subtilis, Micrococcus pyogenes var. aureus, Tricophyton mentagrophytes, and Pityrosporum ovale.The antimicrobial compounds are useful alone, usually in aqueous solution, as microbicides or microbistats. They may also be included as constituents of hairdressings or shampoo because they are effective microbicides, even in the presence of oily materials, such as the sebum normally secreted by the human scalp.

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.
