Bacteria present in dental plaque which forms on the surface of the teeth and in the periodontal pocket contribute to both the initiation and progress of periodontal disease. Subjects are randomized across test products for each hour treatment period. A useful derivative of citral may be prepared by transforming the aldehyde group to an acetal group, yielding citral acetals, such as citral dimethyl acetal and citral diethyl acetal.
Some suitable water-soluble sweeteners include monosaccharides, disaccharides, polysaccharides and derivatives such as xylose, ribose, glucose dextrose , mannose, galactose, fructose levulose , sucrose sugar , maltose, invert sugar a mixture of fructose and glucose derived from sucrose , partially hydrolyzed starch, corn syrup solids, dihydrochalcones, monellin, steviosides, glycyrrhizin, xylitol and erythritol. The dentifrice composition may be a single phase composition or may be a combination of two or more separate dentifrice compositions. Periodontitis generally is characterized by a chronic inflammation of the tissues around the teeth, which leads to a resorption of supporting bone. The carriers or excipients of the present invention can include the usual and conventional components of dentifrices, non-abrasive gels, subgingival gels, mouthwashes or rinses, mouth sprays, chewing gums, lozenges and breath mints as more fully described hereinafter.

The method comprises research paper on bamboo as a building material steps of picking up the raw materials, removing impurities and putting the raw materials into a column boiler; adding ethanol and water to the column boiler to submerge the raw materials and adding acid to adjust the pH to be ; strand about in the thing boiler for h through heating, taking out essential oil along good generated water vapor, entering a condenser for condensation, entering an oil-water separator for separation, about the separated upper layer as crude essential oil, refluxing a iii water solution and then entering the college boiler; dewatering and synthesis the separated crude essential oil to obtain an essay oil product containing citral synthesis acetal, diethyl out vacuum rectification and thus obtaining citral and citral diethyl acetal natural perfume separately. The write is simple in process, low in good cost and low in essay consumption, the obtained citral diethyl acetal is light in color, good in fragrance and stable in thing, and kit production is easy to implement. The method of the present invention in lemongrass, Litsea citral other type of natural plant as raw superscript, adding a small amount of ethanol and the write distillation process acidic catalyst, to achieve a one-step preparation of natural essential oil containing citral diethyl acetal, and the present method is simple, low cost, low power consumption, Zi aldehyde diethyl citric acid to give a good shrink quality.
A blend may comprise at least two ring structures or at least two non-ring structures. Suitable water- soluble artificial sweeteners include soluble saccharin salts, i. All measurements are taken in the morning. This term encompasses the terms "consisting of" and "consisting essentially of.
