Deodorizing cosmetic agent

Deodorizing cosmetic agent. Bore, Pierre; Arnaud, Jean Claude; De Labbey, Arnaud (Oreal S. A., Fr.). Ger. Offen. DE 2703642 4 Aug 1977, 19 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: A61K007-32. PRIORITY: LU 76-74266 29 Jan 1976. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Body deodorants comprise a weak org. acid CnHm(OH)x(CO2H)y (where n = 0 or 1-6; m = 1-8; x = 0, 1 or 2; and y = 1, 2 or 3), a salt of a weak org. acid, and an aminated org. compd. The compns. prevent bacterial decompn. of sweat by holding the pH of the sweat on the skin to a value between 3 and 6. For example, a deodorant spray contained AcOH [64-17-5] 0.53, 2-amino-2-methyl-1,3-propanediol [115-69-5] 0.44, perfume 0.5 and EtOH to 30 g. The compn. was packaged in an aerosol container with 42 g CCl3F and 28 g CCl2F2. When sprayed on an armpit, the compn. kept the pH of the evapd. sweat at 4.9 and prevented odor formation.

Laboratory reagent for use in determining ethanol in liquids

Laboratory reagent for use in determining ethanol in liquids. Bucolo, Giovanni (Calbiochem, USA). Swiss CH 598593 12 May 1978, 3 pp. (German). (Switzerland). CODEN: SWXXAS. CLASS: IC: G01N031-14. APPLICATION: CH 75-13238 13 Oct 1975. DOCUMENT TYPE: Patent CA Section: 4 (Toxicology) Lab. reagents for detn. of EtOH [64-17-5] in body fluids comprise alc. dehydrogenase [9031-72-5] and a mixt. of NAD [53-84-9], a buffer, an aldehyde-intercepting (heavy metal complexing) reagent, and an acid to adjust an aq. soln. of the buffer and aldehyde intercepting reagent to pH 8.8-9.2. The buffer and aldehyde intercepting reagent can be the same compds., such as 2-amino-2-hydroxymethyl-1,3-propanediol (I) [77-86-1] or 2-amino-2-methyl-1,3-propanediol [115-69-5]. For example, I 842, succinic acid [110-15-6] 104, EDTA tetrasodium salt [64-02-8] 26 and NAD 17.2 mg, and 216 unit alc. dehydrogenase were dried over P2O5 and mixed. Before use, the compn. was mixed with 13.5 mL H2O. To conduct the test, 0.1 mL blood serum or saliva was dild. with 4.9 mL H2O, and 0.1 mL of the dil. soln. was mixed with 2.6 mL reagent soln., heated 8-10 min at 30°, and analyzed by UV spectrometry at 340 nm.
