Abstract
Antimicrobial compositions that provide enhanced immediate and residual anti-viral and antibacterial efficacy against rhinovirus, rotavirus, coronovirus, respiratory syncytial virus, Gram-positive bacteria, Gram-negative bacteria and combinations thereof. More specifically, antimicrobial compositions comprising an organic acid or organic acid mixture and a short-chain anionic surfactant having at least one of a large head group; a branched alkyl chain and an unsaturated alkyl chain. Further, products incorporating the antimicrobial compositions of the present invention and methods of using the antimicrobial compositions and products are disclosed herein.
Claims35
An antimicrobial composition capable of inactivating viruses comprising:
- a. from about 0.2% to about 70% of an organic acid, which is pyroglutamic acid or gluconic acid;
- b. from about 0.1% to about 40% of an anionic surfactant mixture having a characteristic selected from the group consisting of:
- i. a linear alkyl chain having a chain length of from about C4 to about C12 and a total hydrophilic head group size of at least about 4 Angstroms;
- ii. an unsaturated alkyl chain having a chain length of from about C4 to about C12;
- iii. a branched alkyl chain having a chain length of from about C4 to about C12;
- and
- iv. combinations thereof;
- and
- c. a calcium ion scavenger, which is citric acid, malic acid, succinic acid, or polyacrylic acid;
- wherein said composition is characterized by a pH of from about 2.0 to about 4.5;
- and
- wherein said viruses include one of at least rotavirus, coronavirus, respiratory syncytial virus, and combinations thereof.
