Agricultural covering films. (Achilles Foam Board Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58076440 A2 9 May 1983 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L027-06; A01G009-14; A01G013-02; C08K005-12. APPLICATION: JP 81-174131 30 Oct 1981. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) Weather-resistant agricultural cover films with excellent antifogging characteristics comprise PVC [9002-86-2] 100, phthalate ester plasticizers 30-60, nonionic surfactants 30.5, and nonionic fluoro surfactants insol. in the plasticizers 0.01-1.0 part. Thus, PVC (d.p. 1300) 100, DOP 45, tricresyl phosphate 3, epoxidized resin 1.5, Ba-Zn soap 1, Ba-Zn liq. stabilizer 1, methylenebisamide 01, nonionic surfactants sorbitan monopalmitate [26266-57-9] 1.0 and sorbitan monostearate [1338-41-6] 1.0, and phthalate-insol. fluoro surfactant Zonyl FSN (I) [57534-41-5] were mixed and formed into 0.1-mm films, which showed min. fogging after 2 mo use in the field, while films made similarly without I showed extensive fogging.

Oil-soluble vitamin B2 butyrate

Oil-soluble vitamin B2 butyrate. Yamamoto, Yoshinori; Okada, Taizo; Morioka, Shigeo; Kaneko, Tsutmo (Sato Pharmaceutical Co., Ltd., Japan). Ger. Offen. DE 3311008 A1 1 Dec 1983, 21 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: A61K031-525; A23L001-30. APPLICATION: DE 83-3311008 25 Mar 1983. PRIORITY: JP 82-91466 31 May 1982. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) A clear oil soln. contg. up to 25% vitamin B2 butyrate [20704-80-7] is prepd. with a glycerol ester of a C4-18 fatty acid, a sorbitan fatty acid ester of a C12-18 fatty acid, a polyoxyethylene sorbitan C12-18 fatty acid ester, or a mixt. of these esters. The solns. have good storage stability (detd. by turbidimetry). Thus, a 2, 10, or 25% soln. of vitamin B2 butyrate in glyceryl caprylate [11140-04-8] (55% monoester) had good storage stability, as did a mixt. of sorbitan stearate [1338-41-6] (50% monoester) 8, polyoxyethylene sorbitan monooleate [9005-65-6] 7, glyceryl caprylate (60% monoester) 45, vegetable oil 20, and vitamin 20%.
