Skin lotion compositions containing quaternary ammonium compounds. Kuriyama, Shojiro; Uragami, Kiyohisa; Tsubone, Kazuyuki (Kanebo, Ltd.Except for chemicals metioned above, 28874-51-3 is also used., Japan). Japan. Kokai JP 53052632 13 May 1978 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A61K007-00. APPLICATION: JP 76-126830 21 Oct 1976. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Skin lotions contg. the quaternary ammonium compds. [RNR1(CH3)2]+Cl- (R = C6-17 alkyl or alkenyl; R1 = benzyl, 4-nitrobenzyl, 3,4-dichlorobenzyl, 2-chlorobenzyl, 4-chlorobenzyl, 2,4-dichlorobenzyl, trichlorobenzyl, methylbenzyl, ethylbenzyl, dimethylbenzyl, Me, etc.), 2-pyrrolidone-5-carboxylic acid Na salt [28874-51-3], alcs., NaCl and H2O were nonirritating to skin, stable, transparent and germicidal. Thus, e.g, a skin lotion contained lauryldimethylbenzylammonium chloride [139-07-1] 0.05, 1,2-pyrrolidone-5-carboxylic acid Na salt 5, EtOH 13, NaCl 0.1, perfumes 0.5 and H2O 81.35 parts. .Except for chemicals metioned above, 28874-51-3 is also used..

Synthetic leather

Synthetic leather. Akamatsu, Akira; Mori, Shigeo; Yamagata, Mineo (Ajinomoto Co., Inc., Japan). Japan. JP 53012562 B4 2 May 1978 Showa, 4 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: D06N003-00. APPLICATION: JP 71-47156 30 Jun 1971. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Leather substitutes prepd. from a polyamide, a polyurethane, etc., were treated with Na 2-pyrrolidone-5-carboxylate (I) [28874-51-3] or 2-pyrrolidone-5-carboxylic acid ethanolamine salt [54243-74-2] to improve bending resistance at low temp. Thus, a soln. contg. MeOH 60, CaCl2 40, and waste nylon 6 fibers 20 parts was coated on a twilled cotton fabric, dried at 70°, immersed in water at 40° to form a porous layer, treated in 10% aq. I for 3 min, and dried to prep. a leather substitute having bending resistance 10000 times at -10°, compared with <1000 times for a similar leather substitute without the I treatment.
