10. ABRASIVE
 Also called as polishing agents
 Cleaning and polishing (function)
 Solid, insoluble particles
 Potential for fluoride interaction
 Causing abrasion.
 Used in dentistry for abrading, grinding, polishing
 Remove debris & residual strain from teeth

11. Types and examples of Abrasives
 Phosphates
 help the product to leave the teeth looking white and feeling clean
 Dicalcium phosphate dihydrate
 Calcium pyrophosphate
 Carbonates
 have been used for nearly 100 years to make a variety of
products and environments fresh-smelling, in addition to their
abrasive properties.
 Sodium bicarbonate: baking soda.
 Calcium carbonate: chalk
 Silicas
 are one of many products in the hydrated silica family, available in
many particle sizes & characteristics

12. BINDERS
 To provide consistency and shape.
 Binders keep the solid phase properly suspended
in the liquid phase to prevent separation of the
liquid phase out of the toothpaste.
 They also provide body to the dentifrice, especially
after extrusion from the tube onto the toothbrush.
 A binder or thickener can prevent the toothpaste
from drying out.
 They control the viscosity and contribute to give the
toothpaste a creamy consistency.

13. Types and examples of Binders

21. SOLVENTS
 Water is the most common solvent used
in toothpaste.
 It dissolves the ingredients and allows
them to be mixed.
 Alcohol is used in mouth rinses as a
solvent and taste enhancer.

22. THERAPEUTIC AGENTS
 One or more therapeutic agents are usually added to
toothpastes.
 Most toothpaste today contain fluorides to prevent
caries.
 Recently there has been a development of 8
different toothpastes with additional purposes, such
as stain and calculus removal, and prevention of
gingivitis, sensitive teeth and gum problems.
