Alkanediol composition, process for producing the same, and cosmetic

Abstract

A less malodorous alkanediol composition, a process for producing the alkanediol composition efficiently, and a cosmetic containing the alkanediol composition are provided. An alkanediol composition contains 0.005 parts by mass or less of ester compound per 100 parts by mass of alkanediol compound having four or more carbon atoms. An alkanediol composition contains 0.2 parts by mass or less of dioxane compound per 100 parts by mass of alkanediol compound having four or more carbon atoms. Furthermore, an ether-containing dihydric alcohol is preferably 0.3 parts by mass or less per 100 parts by mass of alkanediol compound.

1 . An alkanediol composition comprising 0.005 parts by mass or less of ester compound (A) per 100 parts by mass of alkanediol compound having four or more carbon atoms. 
   
   
       2 . An alkanediol composition comprising 0.2 parts by mass or less of dioxane compound (C) per 100 parts by mass of alkanediol compound having four or more carbon atoms. 
   
   
       3 . The alkanediol composition according to  claim 1 , further comprising 0.3 parts by mass or less of ether-containing dihydric alcohol (B) per 100 parts by mass of the alkanediol compound. 
   
   
       4 . The alkanediol composition according to  claim 1 , wherein the alkanediol compound has a general formula (1): 
     
       
         
         
             
             
         
       
       wherein R denotes an alkyl group having 4-15 carbon atoms. 
     
   
   
       5 . The alkanediol composition according to  claim 1 , wherein the alkanediol compound is a hydrolysate of an epoxy compound produced by an oxidation reaction of an olefin. 
   
   
       6 . A process for producing an alkanediol composition, comprising the steps of:
 (a) oxidizing an olefin to produce an epoxy compound;   (b) hydrolyzing the epoxy compound to produce the alkanediol composition; and   (c) adding water and/or an organic solvent to the alkanediol composition and removing water and/or the organic solvent under reduced pressure.   
   
   
       7 . A cosmetic comprising the alkanediol composition according to  claim 1 .
