Discharge printing of synthetic fabrics. Keino, Goro (Matsui Shikiso Kagaku Kogyosho Co., Ltd., Japan). Japan. Kokai JP 51133597 19 Nov 1976 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: D06P005-12. APPLICATION: JP 75-58370 15 May 1975.Chemical with cas number 9002-89-5 also plays role. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Printing polyester or acetate fabrics with pastes contg. a reducing dye discharging agent, subsequently printing the dried fabrics with pastes contg. particles obtained from aq. mixts. contg. a dischargeable dye, a thickener, e.g. poly(vinyl alc.) (I) [9002-89-5], a thickener not compatible with the first thickener, an electrolyte, and optionally contg. a tannin or a phenolic compd., and steaming the fabrics gave printed fabrics with speckled pattern. Thus, a polyester fabric was screen printed with a paste contg. a thickener 65, stannous pyrophosphate [15578-26-4] 10, and H2O 25 parts and dried. Dianix Yellow GFS 5, aq. 10% I 150, aq. 5% Me cellulose [9004-67-5] 50, a mixt. contg. 50% tannin 30, and H3BO3 15 parts were mixed. The dried fabric was screen printed with a mixt. of a compn. [A; contg. the resulting particles (av. diam. 0.1mm) 6, an aq. mixt. contg. 40% natural rubber 64, NH4Cl 1, Na m-nitrobenzenesulfonate 0.5, and H2O to make 100 parts], a compn. similar to A contg. Miketon Discharge Red RN, and a compn. similar to A contg. Miketon Polyester Discharge Blue R at :20 wt. ratio, dried, steamed 20 min at 130.degree., and washed with a detergent to give a printed fabric with multicolored speckled pattern. .

Studies on stannous fluoride toothpaste and gel

Studies on stannous fluoride toothpaste and gel. 1.Several substances are used for example 7783-47-3 and 15578-26-4 which are their cas registry numbers. Antimicrobial properties and staining potential in vitro.

DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 1 Stannous fluoride (SF) in a toothpaste vehicle has the potential to provide anticaries and plaque inhibitory benefits through the fluoride and antimicrobial stannous moieties resp. Dental staining, however, can occur by pptn. of dietary chromogens onto the tooth surface by stannous ions. These studies in vitro compare the antimicrobial profile and propensity to cause tea staining of a no. of stannous fluoride formulations. The formulations used were 2 SF toothpaste products (SF1, SF2), 2 exptl. SF plus stannous pyrophosphate toothpastes (SFSP1, SFSP2), a SF gel (G) and a NaF toothpaste (C). Maximum inhibitory diln. values against a range of oral bacteria were detd. by agar diln. Tea staining was measured spectrophotometrically on saliva coated clear acrylic blocks exposed to slurries of the paste or gel. All formulations showed antimicrobial activity with the order of greatest activity downwards being C, SF2, SF1, SFSP1, SFSP2 and G. Tea staining at 10 exposures was in the following descending order of optical d. SFSP1, SFSP2, G.C, SF1, SF2, water control. The antimicrobial profile of G was similar to that of SF, whereas that of the other formulations were varied but similar to a detergent profile. The difference in staining suggested considerable variation in availability of stannous ions in the formulations. However, the propensity for stannous ions to stain must be balanced against the stain removal propensity of the contained detergents in the toothpaste formulations. In conclusion, the variation in antimicrobial activity and more particularly staining activity of the formulations suggest the products will vary in activity in vivo. .
