  • Publication number: 20050186167
    Abstract: A cleansing composition according to the present invention comprises (A) an aqueous phase containing 1 to 25% by weight of a water-soluble compound (a), which has a polyoxypropylene structure having 3 or more addition number of propylene oxide but neither an alkyl group having 4 or more carbon atoms nor a polyoxyethylene structure, in the aqueous phase and (B) an oil phase which is liquid at 30° C., wherein the weight ratio (A):(B) of the aqueous phase (A) and the oil phase (B) is 97:3 to 40:60, and water is contained more than 10% by weight in the total composition. Moreover, a cleansing sheet according to the present invention comprises a nonwoven fabric which is made of a fiber having a cellulose content of at least 70% by weight and has a density of about 0.15 to 0.

  • Publication number: 20050180942
    Abstract: Provided is a cleansing preparation, which takes a clear liquid form, develops neither a reduction in cleansing power nor deteriorations in appearance and sensation upon application even when water is mixed in, and has resistance to water. The clear liquid cleansing preparation contains the following ingredients (A) to (D): (A) at least one nonionic surfactant selected from: (a) a monoglycerol fatty acid ester having a C12-18 fatty acid residue, (b) a polyglycerol fatty acid ester having a C12-18 fatty acid residue, (c) isostearyl pentaerythryl glyceryl ether, or (d) a liquid nonionic surfactant having polyalkylene glycol chains and exhibiting IOB value of from 0.75 to 1.05, (B) a nonionic surfactant other than the first-mentioned nonionic surfactant (A), and exhibiting IOB value of at least 1.1 (C) a liquid oil ingredient, and (D) at most 12 wt. % of water, wherein the preparation is free of white turbidity when 50 parts by weight of water is added to 100 parts by weight of the preparation.
