Abstract
Methods have been developed for incorporation of peracid compounds and related compositions into a non-aqueous medium. The peracid incorporated into the non-aqueous medium is stable and keeps its chemical and antimicrobial activity for extended durations. The non-aqueous medium may be removed just prior to or during application of the peracid.
Claims25
A stable peracid composition comprising a dissolvable non-aqueous medium and a peracid composition, the peracid composition comprising:
- a carboxylic acid;
- the peracid of said carboxylic acid;
- a peroxy α-ketocarboxylic acid;
- and
- an oxidizer,
- wherein the peracid composition is impregnated in, suspended in, or attached to the dissolvable non-aqueous medium.
A composition comprising:
- a dissolvable polymer;
- a carboxylic acid;
- the peracid of said carboxylic acid;
- a peroxy α-ketocarboxylic acid;
- and
- an oxidizer impregnated in the dissolvable polymer.
A method of stabilizing a peracid compound comprising:
- mixing the peracid compound with a dissolvable polymer in an aqueous solution;
- and
- drying the mixture to make a peracid-containing composition.
A method for sterilizing, disinfecting, or sanitizing hard or porous surfaces or fabrics comprising:
- dissolving a stable composition comprising a non-aqueous medium containing a film polymer, a carboxylic acid, the peracid of said carboxylic acid, a peroxy α-ketocarboxylic acid and an oxidizer;
- separating the non-aqueous medium from the peracid;
- removing the film polymer from the peracid;
- and
- applying the peracid on the surfaces or fabrics.
