Abstract: Compositions having improved anti-plaque and anti-gingivitis activity comprise a synergistic combination of a) a morpholinoamino alcohol or salt thereof, such as 3-(4- propylheptyl)-4-(2-hydroxyethyl) morpholine, and b) a metal salt, such as the salts of divalent zinc, copper and magnesium.

Abstract: The combination of pepper-like constituents, such as piperine, and volatile formate esters, such as ethyl formate, is useful as a substitute for chloroform in pharmaceutical, oral hygiene and confectionery compositions.

Abstract: The invention provides plaque-inhibitory agents useful in oral compositions such as mouthwashes, toothpastes, mouthrinses, dental creams, toothpowders etc. comprising polysaccharides such as xanthan gum, gum tragacanth (pectin), guar gum, gum karaya, chondroitin sulfate, polygalacturonic acid, sodium alginate and carrageenans of the kappa/lambda configuration. The agents are effective in plaque-inhibiting at concentrations between about 0.0025% and 2.000% on a weight/volume basis.

Abstract: The invention provides an oral preparation or composition such as a mouthwash, mouthrinse, toothpaste and the like containing certain classes of surfactants which act to inhibit plaque formation by inhibiting the initial adherence of bacteria to the dentin surfaces and in the case of one class of surfactants additionally inhibiting the glucosyl transferase catalysis to prevent the synthesis of extracellular polysaccharides from sucrose.The surfactants comprise substituted taurines, substituted isethionates and substituted hydroxy sultaines in which the substituents are long chain hydrocarbon radicals. The surfactants are employed in the aqueous-based oral compositions at concentrations between about 0.00001M to 0.1M to effect inhibition.

Abstract: Higher alcohols the logarithm of whose partition coefficient between n-octanol and water is at least 0.61 have been found to exhibit pediculicidal and/or ovicidal activity.

Abstract: Lower alkanol N-substituted fatty acid amides have been found to exhibit pediculicidal and/or ovicidal activity.

Abstract: Certain imidazolines and imidazolium derivatives have been found to exhibit toxicant activity with regard to ectoparasites or their ova, and to other insect species. The insecticidal (including ovicidal, miticidal or aphicidal) activity can in some instances be amplified by the cojoint use of a lower alkanol.

Abstract: Certain propoxylate ethers, block copolymers and one ester has been found to be miticidal. Some members of this group also exhibit pediculicidal and/or ovicidal activity.

Abstract: Alkyl amine oxides have been found to exhibit valuable insecticidal and/or ovicidal activity.

Abstract: An admixture of an aliphatic or aryl aliphatic alcohol and an aliphatic ester has been found pediculicidal.

Abstract: Linear siloxane polymers have been found to exhibit pediculicidal and/or ovicidal activity.

Abstract: Certain substituted glycine compounds have been found to exhibit strong ovicidal activity, with a good degree of insecticidal activity.

Abstract: Certain aminopropionic acids have been found to exhibit ectoparacitisidal activity.
