| abstract |
Aqueous, homogeneous preparations with a content of 0.0025 to 0.1% by weight of antimicrobial biguanide compounds, 0.005 to 0.2% by weight of an alkyl glycoside, 0.01 to 0.3% by weight of a water-insoluble aromatic oil, 0.01 to 0.3% by weight of a solubilizer from the group of the ethoxylated fatty acid glycerides, the ethoxylated fatty acid sorbitan partial esters or the fatty acid partial esters of glycerol or sorbitan oxethylates are highly effective despite the low concentration of antimicrobial biguanide compounds. The clear solubility is achieved without or with very low contents of up to 15% by weight of ethanol. The preparations are preferably suitable as a mouthwash. |
