Aim: To prepare, evaluate and submit herbal toothpaste.
Requirements: Soxhlet apparatus, Heating metal, Beaker, Mortar pestle, Guava leaves, and tubes.
Chemicals: Ethanol, Papain Extract, Calcium carbonate, Sodium lauryl sulfate, Glycerin, Methylcellulose, Sodium saccharine, Methylparaben, Propylparaben, Titanium dioxide, Menthol, and Purified water.
Formulation Consideration: Modern toothpaste formulations were developed in the 19th century. Later on, chalk and soap were incorporated into those formulations. After 1945, several formulation advancements of different detergents had begun; sodium lauryl sulfate had been used as an emulsifying agent. In recent years, the focus has shifted towards the release of active ingredients during formulation developments to prevent and/or treat oral illness.
Toothpaste is a dentifrice used to clean, maintain and improve the health of teeth. Toothpaste is mainly used to promote oral cleanliness and also acts as an abrasive that helps to prevent dental plaque and food particles from the teeth, aids in the removing and/or veiling of halitosis, and releases active ingredients such as fluoride to aid in preventing tooth and gum disease (e.g. Gingivitis).
