Abstract

The object of the present invention is to provide a dermal composition for external use which keeps skin healthy and demonstrates a sufficient effect in treating skin diseases. The present invention relates to a dermal composition for external use, which comprises sodium cromoglycate and a monoester of polyvalent alcohol and salicylic acid contained in a base.

1 . A dermal composition for external use, 
 which comprises sodium cromoglycate and a monoester of polyvalent alcohol and salicylic acid contained in a base.    
   
   
       2 . The dermal composition for external use according to  claim 1 , 
 wherein the monoester of polyvalent alcohol and salicylic acid is glycol salicylate.    
   
   
       3 . The dermal composition for external use according to  claim 1   wherein the content of the monoester of polyvalent alcohol and salicylic acid is 1 to 20% by weight.    
   
   
       4 . The dermal composition for external use according to  claim 1 , 
 wherein said dermal composition for external use contains at least one transcutaneous absorption enhancer selected from the group consisting of N-acyl sarcosine or a salt thereof, a higher fatty acid ester of a C10 to C18 higher fatty acid and a C1 to C20 alcohol, a C2 to C10 dicarboxylic acid or a salt thereof, a hydroxycarboxylic ester of a C3 to C6 hydroxycarboxylic acid and a C1 to C20 alcohol, a fatty acid ethanol amide, glycerin, propylene glycol, polyethylene glycol, urea, glycyrrhizinic acid, squalane and mucopolysaccharide.    
   
   
       5 . The dermal composition for external use according to  claim 4 , 
 wherein the transcutaneous absorption enhancer is at least one member selected from the group consisting of glycerin, propylene glycol, urea, squalane and mucopolysaccharide.    
   
   
       6 . The dermal composition for external use according to  claim 1 , 
 wherein the base is a water-soluble base.    
   
   
       7 . The dermal composition for external use according to  claim 1 , 
 wherein a pH value thereof is of 2 to 7.    
   
   
       8 . The dermal composition for external use according to  claim 1 , 
 wherein a pH value thereof is 4 to 5.    
   
   
       9 . A cosmetic, 
 which is obtainable by using the dermal composition for external use according to  claim 1 .    
   
   
       10 . A pharmaceutical preparation, 
 which is obtainable by using the dermal composition for external use according to  claim 1.
