Anti-plaque toothpaste

Preparation for dental and oral hygiene containing polysaccharide

Oral and dental hygiene preparations containing quaternary ammonium compounds of the formula ##STR1## wherein R.sup.1 is an n-alkyl group, preferably containing from 8 to 12 carbon atoms, R.sup.2 is hydrogen, a CH.sub.3 -group or a CH.sub.2 OH-group and R.sup.3 is a CH.sub.3 -group or a group of the formula --CH.sub.2 --CH(OH)--R.sup.2, A is an inorganic or organic acid anion and n is the basicity of the anion. The quaternary ammonium compounds of formula I can have a plaque inhibiting effect and show only slight antimicrobial activity. R.sup.1 is preferably an n-decyl group, R.sup.2 is hydrogen and R.sup.3 is a CH.sub.3 -group or a 2-hydroxyethyl group. The oral and dent al hygiene preparations also preferably contain fluorides and/or organophosphonates as the anion A.

Oral and dental hygiene preparations

N-octyl salicylic acid amide and N-decyl salicylic acid amide, a process for their production from salicylic acid methyl ester and a primary amine, and use of the amides in antimicrobial compositions.

Alkyl glycosides are used to greatly increase the microbicidal activity of biguanide compounds, such as chlorhexidine salts. The alkyl glycoside/biguanide agents have a particular utility in teeth cleaning preparations due to their improved microbicidal activity against gram-positive bacteria.

Alkyl glycosides as potentiating agents in antiseptic, disinfecting and

Oral and dental preparations containing as an active ingredient an anti-caries effective amount of a C.sub.2-4 alkoxylated trihydric to hexahydric C.sub.3-12 aliphatic polyol wherein at least one hydroxyl moiety is esterified with phosphoric acid, or a physiologically compatible water soluble salt thereof.
