Definitions

  • the invention relates to acidic disinfecting and cleaning compositions for hard surfaces, in particular for apparatuses and working surfaces in the food industry and in the hospital sector.
  • the invention further relates to the use of the compositions for removing fatty and calcareous fouling and for controlling listeriae and salmonellae.
  • Acidic disinfecting and cleaning compositions for apparatuses and working surfaces in the food industry and in the hospital sector are known.
  • a commercial product based on benzalconium chloride, phenoxypropanols and glyoxylic acid which exhibits good microbiological activity, but only a satisfactory cleaning capacity.

  • no disinfecting composition and cleaning composition concentrates are disclosed.
  • it relates particularly to the cleaning of toilet surfaces, which concerns neither the removal of fatty fouling, nor the activity against listeriae and salmonellae.
  • the aggressive volatile pungent formic acid which is corrosive via the gas phase and nonylphenolethoxylate which is poorly biodegradable are used which are no longer recommended for use owing to an undertaking by the industry.
  • It was an object of the present invention to provide an acidic composition which, as diluted ready-to-use solution, exhibits good cleaning activity and good disinfecting activity, may be formulated as a concentrate and, moreover, corresponds to the abovementioned requirements.
  • Inventively used quaternary ammonium salts are described by the formula [R 1 R 2 R 3 (CH 3 )N]+[X] - , where R 1 to R 3 can be identical or different and are selected from the group consisting of C 1 to C 30 alkyl, C 1 to C 30 alkenyl and mixed groups which can have one or more atoms selected from O, S, N and P, where R 1 to R 3 are, for example, C 8 to C 14 alkyl or methyl, preferably C 9 to C 12 alkyl or methyl, such as C 10 alkyl or methyl.
  • X is an anion (of an inorganic or organic acid). Not only anion but also cation of the quaternary ammonium salt can be polyvalent ions, which gives a stoichiometry [A ⁇ n+ ⁇ ] m [K (m+ ⁇ ] n .
  • Quaternary ammonium salts preferably used according to the invention are compounds of the formulae [R 1 N(CH 3 ) 3 ] + [X] - , [R 1 R 2 N(CH 3 ) 2 ] + [X] - and [R 1 R 2 R 3 (CH 3 )N] + [X] - , where R 1 to R 3 independently of one another are selected from C 8 to C 14 alkyl and -(CH 2 -CHR 4 O) n -R 5 , where n is a number from 1 to 20, preferably 1 to 5, and R 4 and R 5 , which can be identical or different, are H and/or C 1 to C 4 alkyl, preferably H.
  • Suitable quaternary ammonium salts are, according to the invention, all quaternary ammonium salts of the abovementioned formula which are known in the prior art as are disclosed, for example, in WO 00/63337, which is incorporated here by reference.
  • dialkyldimethylammonium salts are used, for example dialkyldimethylammonium chlorides, the alkyl chains of which independently of one another are selected from C 8 to C 14 alkyl, preferably C 9 to C 12 alkyl, such as C 10 alkyl.

  • the alcohol content of the inventive composition is set (increased) however to the preferred weight ratio mentioned hereinafter of quaternary ammonium salt to alcohol by additional addition of alcohol.
  • the inventive composition comprises in the form of a concentrate 2 to 30% by weight, preferably 5 to 25% by weight, in particular 10 to 20% by weight, for instance 15% by weight, of the quaternary ammonium salt (or of the two, three, four etc. quaternary ammonium salts).
  • the amount of quaternary ammonium salt here is recorded according to the invention as quaternary ammonium chloride.
  • compositions are free from benzalkonium compound (such as benzalkonium chloride).
  • the invention relates to an acidic disinfecting and cleaning composition which, as quaternary ammonium salt, comprises dialkyldimethylammonium salt (such as dialkyldimethylammonium chloride, in particular didecyldimethylammonium chloride) and which is free from benzalkonium chloride.

  • Preference is also given to compositions which, in addition to didecyldimethylammonium chloride (didecyl-dimonium chloride), comprise no further quaternary ammonium salt.
  • benzalkonium chloride in the system quaternary ammonium compound/acid, is significantly weaker with respect to the cleaning performance towards fatty dirt than the quaternary ammonium salts used according to the invention, correspondingly, the required amount of quaternary ammonium compound which is necessary to remove fatty dirt, is less when the composition is free from benzalkonium compound (in particular benzalkonium chloride) and, as quaternary ammonium compound, only comprises the abovementioned quaternary ammonium salts.

  • alcohol alkoxylates as nonionic surfactants. It was therefore surprising that the cleaning performance in the system quat/organic acid is inhibited by a comparatively high amount of alcohol alkoxylate, as is shown in the examples. It has further surprisingly been found that the alcohol alkoxylates, when they are present in the system in a large amount, impair the disinfecting action of the dilute ready-to-use solution.

  • Example 3 Bactericidal and fungicidal activity of comparative concentrate VII
  • Comparative concentrate VII comprises a higher total concentration of active compound (in total 30% by weight of benzalkonium chloride and glyoxylic acid), compared with the inventive concentrate II (15% by weight of didecyldimethylammonium chloride). It was therefore surprising that the fungicidal activity of the comparative concentrate VII, despite a higher total concentration of active compound, is poorer than that of the inventive concentrate II. The bactericidal activity of comparative concentrate VII was, for the same feed amount, equal to the bactericidal activity of the inventive concentrate II.
