Claims
- 1. A water-in-oil (W/O) emulsion having a viscosity of at most 5000 mPa.s, said W/O emulsion comprising:a) an aqueous phase comprising a content of water and water-soluble substances totaling at least 75% by weight, based on a total weight of the emulsion: b) an oil phase comprising a content of lipids, emulsifiers and lipophilic constituents totaling at least 15% by weight, based on a total weight of the emulsion, wherein the oil phase comprises at least 75% by weight, based on the weight of the oil phase, of one or more substances selected from the group consisting of: i) non-polar lipids which are liquid at room temperature and have a polarity of greater than 30 mN/m; and ii) silicones of any polarity; c) at least one interface-active substance selected from the group consisting of substances of the formula (I); where A and A′ are identical or different organic radicals selected from the group consisting of branched and unbranched, saturated and unsaturated alkyl and acyl radicals and hydroxyacyl radicals having 10-30 carbon atoms, and also from the group consisting of hydroxyacyl groups connected to one another via ester functions in accordance with the following scheme: where R′ is selected from the group consisting of branched and unbranched alkyl groups having 1 to 20 carbon atoms and R″ is selected from the group consisting of branched and unbranched alkylene groups having 1 to 20 carbon atoms, and b is a number from 0 to 200; a is a number from 1 to 100: X is a single bond or the group: R1 and R2 independently represent H or methyl; and R3 is selected from the group consisting of H and branched and unbranched, saturated and unsaturated alkyl and acyl radicals having 1 to 20 carbon atoms.
- 2. The W/O emulsion according to claim 1, wherein a is a number from 2 to 60.
- 3. The W/O emulsion according to claim 2, wherein a is a number from 5 to 40.
- 4. The W/O emulsion according to claim 1, wherein the content of water and water soluble substances is greater than 80% by weight, based on the total weight of the emulsion.
- 5. The W/O emulsion according to claim 4, wherein the content of water and water soluble substances is greater than 85% by weight, based on the total weight of the emulsion.
- 6. The W/O emulsion according to claim 1, wherein the interface-active substance is polyethylene glycol-30-dipolyhydroxystearate.
- 7. The W/O emulsion according to claim 1, wherein the oil phase comprises at least 50% by weight, based on the total weight of the oil phase, of at least one substance selected from the group consisting of Vaseline (petrolatum), paraffin oil and polyolefins.
- 8. The W/O emulsion according to claim 7, wherein the oil phase comprises more than 75% by weight, based on the total weight of the oil phase, of at least one substance selected from the group consisting of Vaseline (petrolatum), paraffin oil and polyolefins.
- 9. The W/O emulsion according to claim 7, wherein the oil phase comprises one or more polydecenes.
- 10. A method of caring for skin or hair comprising topically applying thereto an effective amount therefor of the W/O emulsion according to any one of claims 1-9.
