The present invention relates to a stable composition of HOCl, a process for its production and uses thereof. A composition that forms an aqueous solution of HOCl and a salt MnXy. The composition having a pH of from 4 to 7, wherein M is hydrogen or a metal, X is the conjugate base of an acid having a pKa of between 4 and 7, n and y are independent and wherein the salt MnXy has an overall neutral charge. Preferably the salt is calcium hydrogen phosphate (CaHPO4). Also claimed is a process for the production of the composition comprising the addition of a source of hypochlorite to water and acidification of the HOCl composition to a pH of from 4 to 7 by the addition of an acid with a pKa value of between 4 and 7. The exemplified acid used is phosphoric acid. The composition may be used in the sterilisation of foodstuffs and laundry such as clothing, sheets, mops, towels, carpets, mats, shoes, hats and gloves. The composition may also be used to treat wounds, burns, post surgical wounds and ulcers or to treat topical microbial infection. The composition may also be used to sterilise drinking water. Also claimed is ice comprising the composition. The composition may also be employed as a slimicide or agricultural pesticide or herbicide. The composition may also be fogged or sprayed onto the open wound area during surgical procedures. |
