Foamable Skin Washing Agent

Abstract

To provide a skin washing agent which is excellent in the foaming speed and the foam creaminess in washing therewith, and which, after washing therewith, is excellent in the moist feeling and the absence of pulling feeling of the skin and does not change the moisture content of skin. A foamable skin washing agent comprising (a) a fatty acid salt, (b) one or more selected from a homopolymer, a dipolymer and a terpolymer derived from a specific cationated monomer (e.g., dimethyldiallylammonium chloride), (c) a polyglyceryl monoalkyl ether, and (d) one or more selected from an acylmethyltaurine salt and a hydroxy ether carboxylate salt.

1 . A foamable skin washing agent comprising (a) a fatty acid salt, (b) one or more polymers selected from a homopolymer, a dipolymer and a terpolymer derived from a cationated monomer represented by the following formula (I): 
       
         
           
           
               
               
           
         
         (in formula (I), R 1  and R 2  each independently represent a hydrogen atom, or an alkyl group having from 1 to 4 carbon atoms; and Y −  represents a monovalent inorganic or organic anion), 
         (c) a polyglyceryl monoalkyl ether represented by the following formula (II): 
       
       
         
           
           
               
               
           
         
         (in the formula (II), n indicates an integer of from 6 to 22, and m indicates an integer of 3 or more), 
         (d) one or more selected from an acylmethyltaurine salt and a hydroxy ether carboxylate salt. 
       
     
     
         2 . The foamable skin washing agent as claimed in  claim 1 , wherein component (b) is one or more polymers selected from dimethyldiallylammonium chloride polymers, dimethyldiallylammonium chloride/acrylamide copolymers, and dimethyldiallylammonium chloride/acrylamide/acrylic acid copolymers. 
     
     
         3 . The foamable skin washing agent as claimed in  claim 1 , which contains component (a) in an amount of from 2 to 90% by mass, component (b) in an amount of from 0.01 to 10% by mass, component (c) in an amount of from 0.01 to 20% by mass, and component (d) in an amount of from 1 to 20% by mass.
