A method for preparing a conditioning preshave or aftershave agent, comprising the following steps: a) providing a microemulsion containing a) i) at least one alkyl(oligo)glycoside a) ii) at least one monoester or diester of glycerol that has at least one C 10 -C 24 fatty acid as a co-emulsifier, and additionally a) iii) at least one oil and a) iv) water, wherein the components (i), (ii), (iii) and (iv), in each case based on the weight of the microemulsion, are present in the amounts I, II, III and IV where I = from 15 to 25 wt.%, based on the weight of the microemulsion, II = from 4 to 10 wt.%, based on the weight of the microemulsion, III = from 15 to 25 wt.%, based on the weight of the microemulsion, IV = from 40 to 66 wt.%, based on the weight of the microemulsion, and b) mixing the microemulsion with a hydrous cosmetic carrier, which contains: b) i) at least one alkyl ether phosphate or alkenyl ether phosphate of formula as an emulsifier, in which R 1 represents an aliphatic hydrocarbon functional group having 8 to 30 carbon atoms, R 2 represents hydrogen, a functional group (CH 2 CH 2 O) n R 1, or X, n represents numbers from 1 to 10, and X represents hydrogen, a functional group (CH 2 CH 2 O) n R 1, an alkali metal or alkaline-earth metal, or NR 3 R 4 R 5 R 6, where R 3 to R 6 represent, independently of one another, a C 1 to C 4 hydrocarbon functional group, b) ii) at least one oil that is different from a) iii). a) providing a microemulsion containing a) i) at least one alkyl(oligo)glycoside a) ii) at least one monoester or diester of glycerol that has at least one C 10 -C 24 fatty acid as a co-emulsifier, and additionally a) iii) at least one oil and a) iv) water, wherein the components (i), (ii), (iii) and (iv), in each case based on the weight of the microemulsion, are present in the amounts I, II, III and IV where I = from 15 to 25 wt.%, based on the weight of the microemulsion, II = from 4 to 10 wt.%, based on the weight of the microemulsion, III = from 15 to 25 wt.%, based on the weight of the microemulsion, IV = from 40 to 66 wt.%, based on the weight of the microemulsion, and a) i) at least one alkyl(oligo)glycoside a) ii) at least one monoester or diester of glycerol that has at least one C 10 -C 24 fatty acid as a co-emulsifier, and additionally a) iii) at least one oil and a) iv) water, I = from 15 to 25 wt.%, based on the weight of the microemulsion, II = from 4 to 10 wt.%, based on the weight of the microemulsion, III = from 15 to 25 wt.%, based on the weight of the microemulsion, IV = from 40 to 66 wt.%, based on the weight of the microemulsion, and b) mixing the microemulsion with a hydrous cosmetic carrier, which contains: b) i) at least one alkyl ether phosphate or alkenyl ether phosphate of formula as an emulsifier, in which R 1 represents an aliphatic hydrocarbon functional group having 8 to 30 carbon atoms, R 2 represents hydrogen, a functional group (CH 2 CH 2 O) n R 1, or X, n represents numbers from 1 to 10, and X represents hydrogen, a functional group (CH 2 CH 2 O) n R 1, an alkali metal or alkaline-earth metal, or NR 3 R 4 R 5 R 6, where R 3 to R 6 represent, independently of one another, a C 1 to C 4 hydrocarbon functional group, b) ii) at least one oil that is different from a) iii). b) i) at least one alkyl ether phosphate or alkenyl ether phosphate of formula as an emulsifier, in which R 1 represents an aliphatic hydrocarbon functional group having 8 to 30 carbon atoms, R 2 represents hydrogen, a functional group (CH 2 CH 2 O) n R 1, or X, n represents numbers from 1 to 10, and X represents hydrogen, a functional group (CH 2 CH 2 O) n R 1, an alkali metal or alkaline-earth metal, or NR 3 R 4 R 5 R 6, where R 3 to R 6 represent, independently of one another, a C 1 to C 4 hydrocarbon functional group, b) ii) at least one oil that is different from a) iii).
