Abstract
Cleaning agent for dentine surfaces, particularly when mending teeth, the active constituents of which are invert soap (quaternary ammonium compounds), and ampholytic tenside and a complex forming agent being of aminocarboxylic acid type; the ampholytic tenside is preferably of dicarboxylated imidazoline type.
Claims7
A cleaning agent for dentine surfaces, comprising
- 10 to 90 parts by weight of (1) benzalkonium chloride, and
- 90 to 10 parts by weight of (2) an ampholytic tenside having the formula ##STR13## wherein R is the radical of a fatty acid having on an average of 11 to 19 carbon atoms, R.sub.1 is --CH.sub.2.COOM or M, Z is --COOM or --CH.sub.2.COOM and M is an alkali metal or hydrogen, together with
- (3) an aminocarboxylic acid sequestering agent, wherein the ratio between the amount of benzalkonium chloride and ampholytic tenside to sequestering agent is from 100:1 to 1:100.
A cleaning agent for dentine surfaces, comprising
- 10 to 90 parts by weight of (1) benzalkonium chloride, and
- 90 to 10 parts by weight of (1) an ampholytic tenside comprising a compound having the formula:
- ##STR14## wherein R is the radical of a fatty acid having on an average of 11-19 carbon atoms, R.sub.1 is --CH.sub.2.COOM or M, Z is --COOM, --CH.sub.2.COOM or ##STR15## and M is an alkali metal, hydrogen or the residue of an organic base, or comprising a compound having the formula:
- ##STR16## wherein R.sub.2 is an alkylamino ethyl or propyl group, the alkyl group having 8 to 18 carbon atoms, or an acylamino ethyl or acylamino propyl group, the acyl group of which has 12 to 18 carbon atoms on an average and wherein R.sub.4 and R.sub.5 both are methyl groups or R.sub.4 is hydrogen and R.sub.5 is an electron pair, and
- (3) an aminocarboxylic acid sequestering agent wherein the ratio between the amount of benzalkonium chloride and ampholytic tenside to sequestering agent is 100:1 to 100:1.
