Principle: Tooth powder is the simplest and cheapest form of dentifrices compare to toothpaste. Tooth powder has less solubility problem in formulation because interaction between components is less in absence of water. Oxidizing agent and fluorides retain their effective concentration longer in tooth powder than in toothpaste. It contains abrasive such as precipitated chalk, i.e. calcium carbonate. It is used in small proportion and mixed with larger quantities of other abrasive.It contain dry calcium phosphate which usually provides the toothpaste the pH ranging from 6-8.
It also contain detergent like sodium lauryl sulphate which is necessary to reduce interfacial tension between adherent matter and surface of teeth thereby during cleaning, it help in contains sodium per borate that acts as bleaching agent, which penetration and removed matter in the foam produced. If ale is added to improve the whitening action of tooth powder. They are basically oxidizing agents. Artificial sweeteners such as sodium Saccharin is used to an extent of 0.05-0.25%. Flavour such as peppermint oil is used which improves the characte ristic taste & sensation of freshness in mouth.
- Procedure:
- All solid ingredients are requiring being in fine powder.
- 1. Mix the weighed quantity of sodium saccharine and peppermint oil together with small amount of preci pitated chalk in mortar until uniform mix is obtained.
- 2. In another clean mortar mix sodium lauryl sulphate with sodium per borate lightly by trituration.
- 3. Add flavour solution to this mix and mix by light tritu ration.
- 4. Add Tri calcium phosphate.
- 5. Mix lightly and then gradually incorporate the precipi tated chalk. Mix by light trituration until uniform mass is produced.
- 6. Weigh about 5 gm of tooth powder and fill in container with perforated top.
