Deodorizing preparations

Abstract

The invention relates to novel deodorizing preparations with a synergistically improved performance. The novel preparations contain (a) dialkyl carbonates, (b1) antiperspirants, (b2) esterase inhibitors, (b3) bactericidal or bacteriostatic active substances and/or (b4) perspiration-absorbing substances.

1 . Deodorizing preparations containing 
 (a) dialkyl carbonates corresponding to formula (I):                          in which R 1  is a linear alkyl and/or alkenyl group containing 6 to 22 carbon atoms, a 2-ethylhexyl, isotridecyl or isostearyl group or a group derived from a polyol containing 2 to 15 carbon atoms and at least two hydroxyl groups, R 2  has the same meaning as R 1  or is an alkyl group containing 1 to 5 carbon atoms and n and m independently of one another stand for 0 or numbers of 1 to 100,    (b1) antiperspirants,    (b2) esterase inhibitors,    (b3) bactericidal or bacteriostatic agents and/or    (b4) perspiration-absorbing substances.    
     
     
         2 . Preparations as claimed in  claim 1 , characterized in that they contain trialkyl citrates as the esterase inhibitors.  
     
     
         3 . Preparations as claimed in claims  1  and/or  2 , characterized in that they contain chitosans as the bactericidal or bacteriostatic agents.  
     
     
         4 . Preparations as claimed in at least one of  claims 1  to  3 , characterized in that they contain di-n-octyl carbonates as the dialkyl carbonates.  
     
     
         5 . Preparations as claimed in at least one of  claims 1  to  4 , characterized in that they contain salts of aluminium, zirconium or zinc as the antiperspirants.  
     
     
         6 . Preparations as claimed in at least one of  claims 1  to  5 , characterized in that they contain aluminium zirconium tetrachlorohydrate, aluminium zirconium pentaclorohydrate and complex compounds thereof as the antiperspirants.  
     
     
         7 . Preparations as claimed in at least one of  claims 1  to  6 , characterized in that they contain modified starch, silicates and talcum as the perspiration-absorbing substances.  
     
     
         8 . Preparations as claimed in at least one of  claims 1  to  7 , characterized in that—based on the solids content—they contain 
 (a) 1 to 80% by weight of dialkyl carbonates,  
 (b) 1 to 50% by weight of antiperspirants,  
 (c) 0.01 to 20% by weight of esterase inhibitors,  
 (d) 0.01 to 5% by weight of bactericidal or bacteriostatic agents and/or  
 (e) 0.1 to 30% by weight of perspiration absorbers,  
 with the proviso that the quantities shown add up to 100% by weight with water and other auxiliaries and additives.  
 
     
     
         9 . The use of the preparations claimed in  claim 1  for the production of deodorizing preparations.
