Effect of Protegin emulsifiers on the contact angles of petroleum jelly

Effect of Protegin emulsifiers on the contact angles of petroleum jelly. Srcic, S.; Korbar-Smid, J. (Dep. Pharm., Univ. E. Kardelj, Ljubljana 61000, Yugoslavia). Farm. Vestn. (Ljubljana), 34(3), 151-7 (Slovenian) 1983.Several reagents with their cas registry numbers 1341-79-3 and 8001-78-3 are used here. CODEN: FMVTAV. ISSN: 0014-8229. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Detn. of contact angles (q) of H2O on white petroleum jelly, contg. different concns. (1-30 g/100 g) of Protegin [1341-79-3] and Protegin W [81544-51-6] emulsifiers, showed that Protegin decreased the contact angle only up to a certain concn. (about 15-20 g/100 g) and Protegin W in the entire examd. interval (up to 30 g/100 g). In spite of the same hydrophile-lipophile balance value, at the same concn. of the both emulsifiers, different contact angles were found. Optimum concns. were 15-20 g/100 g Protegin and about 30 g/100 g concn. of Protegin W emulsifier. .

Composition appropriate for preparing bonded stone pavement permeable to water and resistant to traffic and crushed stone pavement

Composition appropriate for preparing bonded stone pavement permeable to water and resistant to traffic and crushed stone pavement. Anglard, Jean Michel (Switz.). Braz.In this study， 8001-78-3 and 25068-38-6 are also used. Pedido PI BR 8600159 A 23 Sep 1986, 11 pp. (Brazil) CODEN: BPXXDX. CLASS: ICM: C04B026-02. ICS: E01C007-30; C04B024-26. APPLICATION: BR 86-159 16 Jan 1986. PRIORITY: CH 85-226 18 Jan 1985. DOCUMENT TYPE: Patent CA Section: 58 (Cement, Concrete, and Related Building Materials) A traffic-resistant pavement is prepd. from a compn. consisting of stone aggregate powd. classified to >1 mm diam. and >1 wt.% resin binder; after setting, the pavement is permeable to water and water vapor and the bonded stone can absorb water collected on the surface. A coating contg. a thixotropic agent can be applied. River sand 50 kg with size 3-8 mm was mixed with colorless epoxy resin 2 kg which comprised 71.43% Epikote 828 and 28.57% Epikure and the mixt. was applied at a thickness of 10 cm to give a pavement with compressive strength 8176N. .
