Toothpastes other ingredients

In the United States more teeth are now lost as a result of gum disease than from decay. Gum disease results from the lack of proper massage, from irritating deposits below the gum line, from bacterial infection, and from poor nutrition.

Others (like glycerin, propylene glycol, or salt) are generally recognized as safe and are reasonable household ingredients. 

By the same token, the inclusion of diagrams could negatively affect students interpretation. Crisp and Sweiry (2006) studied students performance in examination questions. They found that on some occasions the inclusion of a diagram supplemented the verbal information provided in the examination questions whilst on other occasions the use of different diagrams associated with the same verbal questions did not significantly affect students performance. However, when students were provided with Fig. 3.5 and asked for the products of the reaction between hydrochloric acid and sodium carbonate, which is an ingredient of toothpaste, 9% of students gave answers such as shampoo and soap . 

Derivatives of fatty acid from coconut oil are feedstock for a number of diverse nonfood products. Coconut oU fatty acids and glycerol are released by hydrolysis or alcoholysis of the fat. The fatty acids or their methyl esters, which are subsequently fractionated, constimte the starting materials for the oleochemical industry. The byproduct, glycerol, is purified by vacuum distillation. The purified product is, among others, a component of pharmaceutical preparations, an important ingredient in toothpastes, a raw material in the manufacture of nitroglycerol, and the fluid in hydraulic jacks and shock absorbers.

Humectant System The humectant system comprises one or more liquids in which the other toothpaste ingredients are dispersed to provide a stable paste. The liquids are usually glycerol and 70% aqueous sorbitol. Propylene glycol [57-55-6] and polyethylene glycols are used occasionally. The liquids are used alone or in combination. Their water activity is such that they do not support bacteriological growth. The humectant system does not crystallize, and thus the final formulation does not dry out or cause the tube cap to lock to the nozzle. 

Moreover, as mentioned in Section 1.1, different products considered as cosmetics in the EU are considered as OTC drugs in US. These include anti-perspirants, sunscreens, anti-caries toothpastes, anti-dandruff and anti-seborrheic products among others. For each of these product types, FDA has published in 21 CFR parts from 350 to 360 a monograph containing positive lists of the active ingredients that can be employed.
