Chemistry investigatory project XII on toothpaste analysis. Identification of cations and anions present in toothpaste and determine it's quality. Under The Guidance Of: MRS. JANAHI VIJAYAKUMAR. issued by the central board of secondary education (CBSE). This project is absolutely genuine and does not indulge in plagiarism of any kind.
Types of Toothpastes Fluoride Toothpaste They contain Sodium Fluoride (NaF), Stannous Fluoride (SnF2), or Monofluorophosphate (MFP2). The fluoride content is about 1,000 parts per million (ppm). They are all effective in preventing dental caries.
This document summarizes experiments performed to identify ions present in different toothpaste brands. Tests were conducted using Oral-B, Colgate, and Close-Up toothpastes. Reactions with added compounds revealed the presence of ions like CO3, Ca, PO4, I, and CH3COO in the toothpastes.
In this paper we have presented the main components of toothpastes and mouthwashes. For the active ingredients, their supposed effect as therapeutic agents is also ex-plained. The most effective way of preventing the development of dental disease is in controlling the production of dental plaque.
neutralisation with a solution of sodium hydroxide and evaporation to dryness [15, 16]. The separation, identification and determination of anionic surfactants in toothpastes can also be done by HPLC [17] which is surely the quickest method. About 1 g of the toothpaste is dissolved in a mixture of methanol/water
Some commercial toothpastes contain either stannous or sodium fluoride as anticaries agents. Stannous fluoride is described in the National Formulary, XII (1) and sodium fluoride in the U.S. Pharmacopoeia XVII (2). Qualitative and quantitative tests for stannous fluoride as well as other data on its reactions and stability
In this application note, we describe the use of electrolytic eluent generation combined with a high-capacity, hydroxide-selective, anion-exchange column—the IonPac AS18— for the determination of fluoride, MFP, and other inactive anionic ingredients in different toothpastes.
