Abstract
A composition for the generation of chlorine dioxide including at least one non-iodo interhalide, polyhalide or salt thereof having the formula BrmClnFoXp wherein m=0–3, n=0–4, o=0–3, p=0–2, X is a cationic moiety and with the provisos that m+n+o cannot be zero; if m+n+p<2, or mixtures thereof, and at least one source of chlorite ions.
Claims23
A biocidal or bleaching composition comprising:
- a) at least one non-iodo interhalide, polyhalide, or salt thereof having at least one bromide atom in an oxidation state of 0–7, and at least one fluoride atom or at least one chloride atom in an oxidation state of 1–7, or mixtures thereof;
- and
- b) a source of chlorite ions;
- wherein said chlorite ions are oxidized to chlorine dioxide in the presence of said at least one non-iodo interhalide, polyhalide, or salt thereof.
