Abstract
Sanitizing concentrate and "use" compositions comprising aliphatic, short chain fatty acid (i.e., C.sub.6 -C.sub.14 fatty acid), hydrotrope or solubilizer for the fatty acid, hydrotrope-compatible acid so that the concentrate, when diluted with a major amount of water provides a use solution having a pH in the range of 2.0 to 5.0. Sanitizing of substantially fixed, "in-place" processing lines in dairies, breweries and other food processing operations is a particular utility of this invention.
Claims26
A concentrate composition which is capable of being diluted with a major amount of water to form an antimicrobial sanitizing use solution, the concentrate composition comprising:
- (a) an aliphatic, short chain fatty acid;
- (b) an effective amount of an ionic hydrotrope-solubilizer which is capable of solubilizing the aliphatic, short chain fatty acid when the concentrate is diluted with water;
- and
- (c) sufficient hydrotrope-solubilizer-compatible acid so that the antimicrobial sanitizing use solution has a pH in the range of about 2.0 to 5.0.
The concentrate which is capable of being diluted with a major amount of water to form a low-foaming, antimicrobial sanitizing solution, the concentrate comprising:
- (a) a fatty acid of the structure R.sub.1 -COOH R.sub.1 being a linear, saturated, branched or unbranched hydrocarbon chain having about 7 to 13 carbon atoms;
- (b) an effective amount of an ionic hydrotrope-stabilizer which is capable of solubilizing the fatty acid when the concentrate is diluted with water;
- and
- (c) sufficient hydrotrope-sanitizer compatible acid so that the antimicrobial sanitizer use solution has a pH in the range of about 2.0 to 5.0.
A low foaming, aqueous, antimicrobial, sanitizing composition which comprises:
- (a) at least about 50 parts per million (ppm) short chain aliphatic fatty acid having about 6 to 14 carbon atoms;
- (b) at least about 100 ppm of a hydrotrope-solubilizer for the fatty acid;
- and
- (c) sufficient hydrotrope-solubilizer-compatible acid so that the composition has a pH in the range of 2.0 to 5.0.
