The invention relates to novel cosmetic preparations comprising an O/W emulsion, where the O/W emulsion comprises at least one amphiphilic polymer comprising one or more hydrophobic units A and one or more hydrophilic units B, where the hydrophobic units A are formed from polyisobutenes modified with terminal, polar groups, at least one component with an HLB value in the range from 8 to 20, and at least one oil and/or fat phase and water.
