                Application 08/004,075                                                                                                        


                (an aliphatic C  peroxycarboxylic acid)(see Beilfuss, column 2,

                lines 19-49).  Beilfuss teaches the addition of peracetic or

                achieve a reduction in the crystallization temperature (column 3,                                                             
                lines 36-43).  Beilfuss also teaches that the composition can                                                                 
                contain biocidal compounds stable to oxidation “such

                (column 4, lines 44-48).  The amounts of these additives used can                                                             
                be up to about 5% by weight of the solution (column 4, lines 52-                                                              
                53).  The pH of the solution is acidic or neutral (column 5,                                                                  
                lines 15-17).  None of the examples disclose the use of any                                                                   
                peroxycarboxylic acid additives.

                rejection under 35 U.S.C.  102 to be proper, the reference must

                         3To be prior art under section 102(b), a reference must
