Abstract: An O/W emulsion contains: (a) at least one oil; (b) at least one fatty alcohol; (c) at least one acid selected from hydroxyl acids, phytic acid, and mixtures thereof; (d) at least one polyglyceryl fatty acid ester having a C6-C32 fatty acid residue; (e) at least one thickener; (f) at least one powder; and (g) water, wherein the HLB of the (d) polyglyceryl fatty acid ester having a C6-C32 fatty acid residue or the weighted average of HLB values of the (d) polyglyceryl fatty acid esters having a C6-C32 fatty acid residue is between 8.0 and 11.5. The composition includes the (c) acid, but it is stable and can provide no sticky feeling or a reduced sticky feeling as well as a non-greasy feeling or smooth feeling.
