Abstract
A food additive microbicidal composition consisting essentially of a major portion of carrier and an effective sanitizing amount of octanoic acid. Optionally, the invention may also consist essentially of any variety of formulatory ingredient options or application adjuvants. The invention comprises concentrate compositions and methods of sanitizing and disinfecting using the antimicrobial composition of the invention.
Claims48
An antimicrobial food grade composition consisting essentially of a major portion of carrier and a sanitizer, said sanitizer consisting of a C.sub.8 carboxylic acid or derivatives thereof wherein there is about 0.02 wt-% to 0.5 wt-% octanoic acid or derivatives thereof wherein said composition has a pH ranging from about 2.2 to 3.3.
An antimicrobial food grade composition consisting essentially of:
- (a) a sanitizer, said sanitizer consisting of from about 0.02 wt-% to 0.5 wt-% octanoic acid or derivatives thereof;
- (b) from about 0.01 wt-% to 10 wt-% of a nonionic surfactant;
- (c) an effective amount of acidulant comprising lactic acid to provide a pH from about 2.2 to 3.3 upon dilution;
- and
- (d) a major portion of carrier comprising water and up to about 20 wt-% ethanol.
An aerosol antimicrobial food grade composition consisting essentially of:
- (a) a sanitizer, said sanitizer consisting of from about 0.02 wt-% to 0.35 wt-% octanoic acid or derivatives thereof;
- (b) from about 0.01 wt-% to 1 wt-% of nonionic surfactant;
- (c) an effective amount of acidulant comprising lactic acid to provide a pH from about 2.2 to 3.3 upon dilution;
- and
- (d) a carrier comprising from about 10 wt-% to 26 wt-% ethanol, up to about 10 wt-% propylene glycol or glycerol, from about 4 wt-% to 10 wt-% isobutane and the balance water.
An antimicrobial food grade concentrate composition consisting essentially of a major portion of carrier and from about 1 wt-% to 45 wt-% of a sanitizer, said sanitizer consisting of octanoic acid or derivatives thereof wherein there is at least about 1 wt-% octanoic acid or derivatives, or mixtures thereof and upon dilution said concentrate results in a composition having a pH ranging from about 2.2 to 3.3.
A liquid antimicrobial food grade concentrate composition consisting essentially of:
- (a) of a sanitizer, said sanitizer consisting of from about 1 wt-% to 45 wt-% octanoic acid or derivatives thereof;
- (b) from about 1.5 wt-% to 45 wt-% of a nonionic surfactant;
- (c) an effective amount of acidulant comprising lacetic acid to provide a pH from about 2.2 to 3.3 upon dilution;
- and
- (d) a carrier comprising water and up to about 25 wt-% propylene glycol.
A solid antimicrobial food grade concentrate composition consisting essentially of:
- (a) of a sanitizer, said sanitizer consisting of from about 1 wt-% to 30 wt-% octanoic acid or derivatives thereof;
- (b) from about 0.1 wt-% to 50 wt-% of a nonionic surfactant having the formula:
- HO(CH.sub.2 CH.sub.2 O).sub.x (CH(CH.sub.3)CH.sub.2 O).sub.y (CH.sub.2 CH.sub.2 O).sub.z H
- wherein x and z range from about 120 to 140 and y ranges from about 50 to 60;
- (c) an effective amount of acidulant comprising latic acid to provide a pH of 2.2 to 3.3 upon dilution;
- and
- (d) a carrier comprising from about 50 wt-% to 75 wt-% urea, up to about 12 wt-% water, and up to about 12 wt-% propylene glycol.
An antimicrobial food grade gel consisting essential of:
- (a) from about 1 wt-% to about 25 wt-% of a sanitizer, said sanitizer consisting of octanoic acid or derivatives thereof;
- (b) from about 5 wt-% to 40 wt-% of a nonionic surfactant;
- (c) an effective amount of acidulant comprising lactic acid to provide a pH from about 2.2 to 3.3 upon dilution;
- and
- (d) a carrier comprising water.
A method of using an antibacterial composition, said method comprising the steps of:
- (a) providing an antimicrobial food grade composition consisting essentially of a major portion of carrier and from about 0.02 wt-% to 0.5 wt-% of a sanitizer, said sanitizer consisting of octanoic acid or derivatives thereof wherein said composition has a pH ranging from about 2.2 to 3.3;
- and
- (b) applying said composition to the intended surface.
