Abstract:
A stabilized biocidal composition comprising a mixture of a halopropynyl compound, a UV absorber and an organic epoxide, wherein an amount of said UV absorber and an amount of said organic epoxide are provided which synergistically stabilizes said halopropynyl compound, and wherein said organic epoxide has the formula: whereinR1, R2, R3, and R4 are independently selected from hydrogen; alkyl having 1-20 carbons; substituted alkyl; halogen; hydroxy; aryl; substituted aryl; alkoxy; alkoxyalkyl; 2,3-epoxy dialkoxyalkyl; aryl; aralkyl; aryloxy; aryloxyalky; alkanoyl; â€ƒwherein Z is selected from the group consisting of straight or branched chain lower alkylene and halo-substituted lower alkylene; and â€ƒwherein Q is selected from the group consisting of alkylene having 1-4 carbon atoms and carbonylarylcarboxy; or R1 and R2 or R2 and R4 may be joined together with the carbon atoms to which they are attached to form an alkylene chain of from 3 to 7 carbon atoms, which chain may be substituted with a lower alkylene to form a bicycloalkane or with a lower alkenyl radical; wherein each of these groups may be further substituted with one or more additional epoxide groups.
