Definitions
- the present invention relates to aqueous cleaning compositions comprising anionic surfactant, nonionic surfactant and organic acid and a method and use thereof to cleaning and disinfect surfaces.
- Cleaning products are well-known and play an important role in everyday life. Such products will contain surfactant and, if disinfection is desired, usually also a disinfecting agent like for example chlorine bleach, quaternary ammonium compound, e.g., benzalkonium chloride, or chloroxylenol.
- a disinfecting agent like for example chlorine bleach, quaternary ammonium compound, e.g., benzalkonium chloride, or chloroxylenol.
- Such conventional disinfecting agents seems to be effective on wide range of microbes, however, it is reported that such agents may affect one’s health.
- Organic acids like citric acid and lactic acid are natural alternatives for synthetic disinfectants like chlorine bleach, benzalkonium chloride and chloroxylenol. These organic acids show antibacterial action, but on their own may not display a broad-spectrum antibacterial action, i.e. act against both gram-negative bacteria (e.g. E. coli and P. aeruginosa) and gram-positive bacteria (e.g. S. aureus and E. hirae). Bacteria like E. hirae are known to be more difficult to combat. Also, antiviral action may be limited in efficacy and/or breadth, e.g. only against enveloped virus and not against non-enveloped virus. Non-enveloped viruses are known to be more difficult to combat.
- WO 2004/18599 discloses an acidic hard surface composition which provides cleaning and disinfecting benefit comprising an acidic constituent, which comprises water soluble organic acid, at least one anionic surfactant constituent, at least one non-ionic surfactant, at least one organic solvent constituent, optionally one or more further constituents and balance water.
- the composition exhibits surprising efficacy against various gram positive and gram-negative type pathogenic bacteria, as well as against fungi in the absence of known cationic quaternary ammonium compounds known to be effective against pathogenic bacteria, as well as other known-art antimicrobial constituents and bleach are excluded.

- compositions were tested neat (i.e., undiluted) or diluted. Dilution is indicated by times of dilution. For example, 200x dilution means that to 10 ml of cleaning composition water is added to a total volume of 2000 ml. Determination of antimicrobial efficacy:
- Dilution neutralization method a. At the end of contact time, 1 mL of test mixture is transferred to 9 mL of neutralizing broth (this is minus 1 (-1) dilution), b. Serial dilutions were prepared to determine the actual survivor counts; and c. Neutralization validation method is described at the end.
- Dilution neutralization method used was as follows: a. To 8 ml of highest test concentration of test product dilution, 1 ml of saline + 1 ml of BSA (clean or dirty) is added, b. After 5 minutes, transfer 1 ml of above mixture to tube containing 8 ml of neutralizing broth to be validated, c. Add 1 ml of 10' 5 dilution i. e 10 3 cells of test organism suspension (diluted from 10 8 cells/ ml test culture suspension in sterile saline) to the above tube and wait for 30 minutes. Consider this tube as undiluted test system; and d. After 30 minutes, plate out undiluted test system and -1 dilution.
