Hair conditioning compositions

Hair conditioning compositions. (Johnson Co., Ltd.Several substances are used for example 142-91-6 and 25322-68-3 which are their cas registry numbers., Japan). Jpn. Kokai Tokkyo Koho JP 58170708 A2 7 Oct 1983 Showa, 3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A61K007-06. APPLICATION: JP 82-51967 30 Mar 1982. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Hair conditioning compns. consist of bis(2-pyridylthiol 1-oxide) metal salts, heat-producing substances (such as ethylene glycol [107-21-1] that produces heat when mixed with H2O) and a substance (sp. gr. < 10) that is difficulty miscible with the heat-producing substance. Thus, polyethylene glycol (PEG) [25322-68-3] 200 50.5, PEG 600 25.0, PEG 13,0003.0 and hydroxypropyl cellulose 0.5 g were mixed and heated, followed by the addn. of propylene glycol [57-55-6] 15.0, benzalkonium chloride 0.5, isostearyl alc. [27458-93-1] 2.0 , bis(2-pyridylthiol 1-oxide) zinc salt [13463-41-7] 0.5 and isopropyl palmitate [142-91-6] 2.0 g to produce a hair-conditioning compn. (2-Pyridylthiol 1-oxide) zinc salt is capable of the prevention of dandruff. .

A study of biocides for the selection of candidates for carcinogen bioassay

A study of biocides for the selection of candidates for carcinogen bioassay. Johnson, O. H.; Casey, S.; Doeltz, M. K.; McCaleb, K. E.; Miller, A. M.; Papa, P. A.; Swett, L. B.; Valentini, M. A.; Helmes, C. T. (SRI Int., Menlo Park, CA 94025, USA). J. Environ. Sci. Health, Part A, A19(1), 1-25 (English) 1984. CODEN: JESEDU. ISSN: 0360-1226. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The class of biocides was studied to nominate chems. as candidates for carcinogen bioassay to the National Cancer Institute. 95-95-4 and 4719-04-4 which are cas registry numbers of substances are two of reagents here. After the application of several qualifying criteria that related to previous, current, or planned carcinogenicity and to com. significance, the preliminary candidate list of 295 chems. was reduced to 61 final candidate chems. Based upon consideration of both the suspicion of possible carcinogenic activity and evidence indicating potential human exposure, the following 8 chems. were nominated: benzethonium chloride [121-54-0], hexahydro-1,3,5-tris(2-hydroxyethyl)triazine [4719-04-4], benzyldimethyl(mixed alkyl)ammonium chloride, N-(3-chloroallyl)hexaminium chloride [4080-31-3], 2,4,5-trichlorophenol [95-95-4], o-benzyl-p-chlorophenol [120-32-1], 1,2-benzisothiazolin-3-one [2634-33-5], and Zn pyrithione [13463-41-7]. .
