This invention is a cosmetic material containing a pasty composition obtained by adding at least one acidic substance selected from a group comprising organic acids, phosphoric acid and phosphates to a mixture comprising a crosslinking type organopolysiloxane polymer having a polyoxyalkylene group and a liquid oil, adding a basic neutralizing agent to adjust the pH to 5-8, and removing volatile components by heating and/or decompression . This pasty composition is a composition wherein the propionaldehyde amount produced by adding an identical amount of water to the composition and heating at 60 DEG C for 24 hours is 100 ppm or less.
