Patent number: 8668923Abstract: Washing with conventional filmy soaps cannot bring about clean detergent effect because of the remaining sliminess due to the ingredient essential for forming soap into films. Further, when moisture adheres to conventional filmy compositions, the water-soluble polymer or other ingredients contained in the compositions dissolve in the moisture to cause the blocking of filmy compositions, which makes it impossible to take out the filmy compositions one by one. Detergent effect without sliminess and the antiblocking of filmy compositions can be attained by incorporating a granular component into a filmy composition containing a water-soluble polymer. The filmy compositions of the invention are used as filmy facial masks, whitening masks, sheet soap, cleansing sheets, sheet shampoos, sheet rinses, sheet bath additives, and so on.Type: GrantFiled: December 14, 2006Date of Patent: March 11, 2014Assignee: P & PF Co., Ltd.Inventors: Yoshinobu Saito, Shinya Yamazaki, Uhei Tamura, Tetsuo Nishina
