Ink-like nail polish. Jankewitz, Axel (Firma A. W. Faber-Castell, Fed. Rep. Ger.). Ger. Offen. DE 3247172 A1 28 Jun 1984, 13 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: A61K007-043; A45D034-04. APPLICATION: DE 82-3247172 21 Dec 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) A nail polish that contains dyes but no pigments and that can be applied with a wicklike device consists of 25-35% of an alk. polyester with an acid no. 380, 1-10% of 25% NH4OH or an equiv. amt. of a volatile alkyl amine, 5-12% of acid org. dye suitable for use in cosmetics, in an aq. vehicle that can contain other additives, including C2-4 alc. or shellac. A neutral-red polish contained satd. terephthalate polyester with an acid no. of 110 25, vinyl acetate-vinylpyrrolidinone copolymer [25086-89-9] 17, iso-PrOH 17, Et lactate 8, 25% NH4OH 7, dye mixt. 10, and H2O to 100%. The dye mixt. consisted of Eosine S13 [15086-94-9] 27, Erythrosine I [16423-68-0] 33, and eosinic acid [596-03-2] 40% by wt. The polish had a viscosity of 130 cP. When applied to fingernails, the clear transparent polish dried within 2 min.

Regression Analysis of Rate Parameters for the Photoinduced Electron Transfer Reaction

Regression Analysis of Rate Parameters for the Photoinduced Electron Transfer Reaction. Korobov, V. E. (Volgograd State Pedagogical University, Volgograd 400131, Russia). High Energy Chemistry (Translation of Khimiya Vysokikh Energii), 36(5), 316-321 (English) 2002 MAIK Nauka/Interperiodica Publishing. CODEN: HIECAP. ISSN: 0018-1439. DOCUMENT TYPE: Journal CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The dependence of the rate const. for the quenching of the triplet state of xanthene dyes by cyanide complexes of transition metals on the free energy change of the photoinduced electron transfer reaction is correlational, rather than functional, in character. Exptl. 15086-94-9 and 2321-07-5 are cas registry numbers of chemicals which are used as reagents here., it was proved that there is no spin forbiddance in the photoinduced electron transfer reaction between these reactants. For the photoreactions with reactants in which dyes are electron acceptors, the values of the intrinsic barrier of electron transfer and the pre-exponential factor of the reaction rate const. were detd. A method for the detn. of calcn. errors for these values was proposed. .
