This cosmetic for shower use contains as an essential ingredient a polyethylene glycol (PEG)/polyoxypropylene glycol (PPG) copolymer. The cosmetic for shower use preferably further contains polyvinyl alcohol (PVA), and more preferably a beautifying agent. Due to this feature, a constant rate of elution in cold or hot water can be ensured, while also minimizing excessive solubility so as to afford satisfactory persistence of solid shape.
