FROST-RESISTANT EMULSION WATER-IN-OIL COMPOSITIONS FOR PURIFICATION AND/OR POLISHING Russian patent published in 2022 - IPC C09K23/00 C09G1/04 

FIELD: chemistry.

SUBSTANCE: present invention relates to emulsion water-in-oil (hereinafter – W/O) compositions. An emulsion W/O composition for inclusion to a composition of an agent for purification or polishing of furniture, shoes, or cars is described, including: (a) 3-40% by wt. of one or several alkanes, alkenes, alkynes, or aromatic hydrocarbon solvents, (b) 0.01-5% by wt. of one or several non-ionogenic emulsifiers having a value of HLB from 2 to 6, and (c) water for balancing the content of composition components up to 100%, where the specified composition additionally contains (d) 0.01-10% by wt. of one or several freezing-defrosting stabilizers, which are one or several compounds of: polyol, sugar, polar aprotic solvent, or amphoteric compound. In this case, (a), (b), (c), and (d) form an emulsion W/O composition, in which a water phase is evenly dispersed in an oil phase, and in which the specified one or several freezing-defrosting stabilizers are present either for (1) prevention of destruction of the specified emulsion during freezing-defrosting, or for (2) provision of reduction of the emulsion composition by shaking after destruction due to freezing-defrosting.

EFFECT: invention provides new emulsion W/O compositions, which can be reduced by simple shaking of compositions after destruction due to multiple freezing-defrosting.
