Abstract
Toothpastes containing 10 to 60% by weight of a polishing agent, 2 to 20% by weight of a humectant, 0.5 to 5% by weight water-soluble consistency regulators, 0.02 to 0.5% by weight antibacterial biguanides and 1 to 5% by weight other additives from the group consisting of surfactants, flavoring oils and sweeteners show particularly high biguanide availability if they contain predominantly .alpha.-aluminium oxide trihydrate as the polishing agent, nonionic polysaccharide derivatives as the consistency regulators, an alkyl glycoside and, optionally, a nonionic solubilizer for the flavoring oil as surfactants and L-aspartyl-L-phenyl alanine methyl ester as sweetener.
Claims16
A toothpaste in the form of an aqueous dispersion comprising:
- 10 to 60% by weight polishing agents,
- 2 to 20% by weight humectants
- 0.5 to 5% by weight of water-soluble consistency regulators,
- 0.02 to 0.5% by weight of antimicrobial biguanides selected from the group consisting of water-soluble, physiologically compatible salts of chlorhexidine,
- 1 to 5% by weight of other additives from the group consisting of surfactants, flavoring oils, and sweeteners,
- wherein the improvement comprises the presence in the toothpaste of:
- predominantly .alpha.-aluminium oxide trihydrate, said .alpha.-aluminum oxide trihydrate having particles predominantly smaller than 50 micrometers in size with an average of approximately 1 to 50 micrometers, as polishing agent,
- nonionic polysaccharide derivatives as consistency regulators,
- an alkyl glycoside and, optionally, a nonionic solubilizer for the flavouring oil as surfactants, and
- L-aspartyl-L-phenyl alanine methyl ester as sweetener.
