Abstract
A disinfectant-containing hard surface cleaner composition having increased bacteria count-reducing efficacy is provided by adding thereto a mixture of an alkyl or alkenyl oligoglycoside and certain C.sub.8 -C.sub.18 alkyl ethers.
Claims4
The process of increasing the bacteria count-reducing efficacy of a hard surface disinfectant-cleaner composition containing from 0.01% to 5% by weight of a disinfectant comprising nitrogenous substances obtained by reacting
- .alpha.) -N-substituted propylene diamines corresponding to formula III
- R.sup.3 --N(R.sup.4)--CH.sub.2 --CH.sub.2 --CH.sub.2 --NH.sub.2 (III)
- in which R.sup.3 represents a linear alkyl group with 6 to 22 carbon atoms, and in which R.sup.4 represents H or CH.sub.2 --CH.sub.2 --CH.sub.2 --NH.sub.2 with compounds corresponding to formula IV ##STR5## in which R.sup.5 represents an alkyl group with 1 to 4 carbon atoms or hydrogen atom,
- .beta.) and optionally further reacting the products obtained according to .alpha.) with ethylene oxide or propylene oxide,
- .gamma.) and optionally, with salts of the products obtained according to .alpha.) or .beta.) with inorganic or organic acids,
- comprising adding to said composition a mixture of:
- a) from 0.2% to 10% by weight of an alkyl or alkenyl oligoglycoside corresponding to formula I
- R.sup.1 --O--G!.sub.p (I)
- in which R.sup.1 represents a linear or branched alkyl or alkenyl group with 8 to 22 carbon atoms, G! represents a glycose unit with 5 or 6 carbon atoms, and p represents a number from 1 to 10, and
- (b) from 0.1% to 10% by weight of an alkyl ether corresponding to formula II ##STR6## in which R.sup.2 represents a linear or branched aliphatic alkyl or alkenyl group with 8 to 18 carbon atoms, x represents 0 or a number of up to 3, and y represents a number from 1 to 15, all weights being based on the weight of said composition.
The process of cleaning and disinfecting a hard surface comprising contacting said surface with a disinfectant-cleaner composition containing from 0.01% to 5% by weight of a disinfectant comprising nitrogenous substances obtained by reacting
- .alpha.) -N-substituted propylene diamines corresponding to formula III
- R.sup.3 --N(R.sup.4)--CH.sub.2 --CH.sub.2 --CH.sub.2 --NH.sub.2 (III)
- in which R.sup.3 represents a linear alkyl group with 6 to 22 carbon atoms, and in which R.sup.4 represents H or CH.sub.2 --CH.sub.2 --CH.sub.2 --NH.sub.2 with compounds corresponding to formula IV ##STR8## in which R.sup.5 represents an alkyl group with 1 to 4 carbon atoms or hydrogen atom,
- .beta.) and optionally further reacting the products obtained according to .alpha.) with ethylene oxide or propylene oxide,
- .gamma.) and optionally with salts of the products obtained according to .alpha.) or .beta.) with inorganic or organic acids,
- and a mixture of
- a) from 0.2% to 10% by weight of an alkyl or alkenyl oligoglycoside corresponding to formula I
- R.sup.1 --O--G!.sub.p (I)
- in which R.sup.1 represents a linear or branched alkyl or alkenyl group with 8 to 22 carbon atoms, G! represents a glycose unit with 5 or 6 carbon atoms, and p represents a number from 1 to 10, and
- b) from 0.1% to 10% by weight of an alkyl ether corresponding to formula II ##STR9## in which R.sup.2 represents a linear or branched aliphatic alkyl or alkenyl group with 8 to 18 carbon atoms, x represents 0 or a number of up to 3, and y represents a number from 1 to 15, all weights being based on the weight of said composition.
