PCT No. PCT/EP96/05526 Sec. 371 Date Nov. 18, 1998 Sec. 102(e) Date Nov. 18, 1998 PCT Filed Dec. 11, 1996 PCT Pub. No. WO97/22548 PCT Pub. Date Jun. 26, 1997The stabilization of solid peroxo and peroxy compounds, in particular of sodium percarbonate and acetyl peroxyborate compounds is described, which can be achieved by coating the peroxo and peroxy compounds with a coating material which is a mixture of essentially a) a fatty acid or preferably an alkali metal or alkaline earth metal salt thereof and b) an anionic surfactant from the group of longer chain substituted sulphonates and sulphates.
