PCT No. PCT/GB91/01589 Sec. 371 Date Apr. 27, 1993 Sec. 102(e) Date Apr. 27, 1993 PCT Filed Sep. 17, 1991 PCT Pub. No. WO92/06036 PCT Pub. Date Apr. 16, 1992.A composition having improved physical stability comprising an aqueous peroxidic solution of an alkali metal oxyboron compound containing alkali metal to boron in a substoichiometric mole ratio into which there has been introduced an effective stabilizing amount of cyclohexane -1,2-diaminotetra (methylene phosphonic acid) or a water soluble salt thereof. Also a process for enhancing the physical stability of an aqueous peroxidic solution of an alkali metal oxyboron compound containing alkali metal to boron in a substoichiometric mole ratio which is characterized by introducing into the solution an effective stabilizing amount of cyclohexane -1,2-diaminotetra (methylene phosphonic acid) or a water soluble salt thereof.
