摘要:
The invention concerns granules obtainable by drying an inverse emulsion, dispersed in an external aqueous phase: a) the inverse emulsion comprising an internal aqueous phase, including a hydrophilic active material, dispersed in an internal organic phase, said inverse emulsion including at least a non-ionic surfactant and/or at least an amphiphilic block polymer, and/or at least a cationic surfactant; b) the external aqueous phase including: at least a polyalkylated non-ionic surfactant and/or at least a polalkylated amphiphilic non-ionic polymer; at least a water soluble or water dispersible polymer in solid form in the presence of a water content of not more than 10 wt. % relative to the weight of said polymer and whereof the glass transition temperature is higher than 25° C., preferably higher than 50° C. The granules, once dispersed, enable to obtain a multiple emulsion.
摘要:
The invention concerns solid granulates of a system comprising at least a hydrophobic organic active substance (for example an active detergent substance) encapsulated in solid particles of an alkali-water soluble organic polymer derived by emulsion polymerisation, said particles being dispersed in and encapsulated by a matrix in a water soluble or water dispersible dry organic compound. The invention also concerns the use of said granulates in detergent compositions, in particular for cleaning hard surfaces or for washing clothes and the detergent compositions.

摘要:
The invention concerns a method for preparing an oil-in-water emulsion whereof the organic phase has a viscosity not less than 1 Pa.s, which consists in using an aqueous phase comprising at least a heat-thickening polymer having a viscosity jump between 25 and 80° C. so that the value of the ratio log 10 (viscosity at 80° C.)/log 10 (viscosity at 25° C.) is at least equal to 1, preferably at least equal to 2, the variation in viscosity being reversible; the amount of heat-thickening polymer being such that the aqueous phase viscosity is 0.2 to 5 times that of the organic phase at the temperature for preparing the emulsion; the latter being not less than the thickening temperature of the heat-thickening polymer.
摘要:
This invention concerns the use, in a cold drawing lubricating solution, as adhesive and lubricating agent, for a steel wire trimmed with brass and rubber, of an aqueous suspension comprising at least a cobalt and/or nickel salt compound of a saturated or unsaturated carboxylic acid (i), or a phosphate ester (ii), or a cobalt and/or nickel boroacylate (iii); and at least a non-ionic or anionic surfactant; the compound (i), (ii), and/or (iii)/surfactant weight ratio ranging between 0.5 and 10. The invention also concerns said suspension and preparation methods thereof. The invention further concerns a cold drawing lubricating solution comprising said suspension.
