Water; Sorbitol; Calcium Carbonate; PEG-6; Sodium Magnesium Silicate; Hydrated Silica; Sodium Lauryl Sulfate; Flavour; Cellulose Gum; Sodium Monofluorophosphate; Sodium Saccharin; Calcium Glycerophosphate; Sodium Hydroxide; Cl 77891; Cl 73360; Cl 42090.
Water
Water is present in toothpaste as a diluting agent.
Mr = 18 g.mol-1
Sorbitol
Sorbitol is essentially an emulsifying agent. It enhances foaming and imparts viscosity, giving good consistency and plasticity. Other functions are to prevent drying and to enhance the cooling effect of the paste.
Mr = 182 g.mol-1
Synonyms: Clucitol; Sorbite; D-Glucitol; D-Sorbitol; D-Sorbit; L-gulitol; Glucitol; Gulitol; D-galactitol.
Calcium Carbonate
Solid calcium carbonate acts as an abrasive and cleaning agent for removing stains and plaque.
Mr = 100 g.mol-1
PEG-6
PEG-6 is an abbreviation for a polyethylene glycol.
Like sorbitol, PEG-6 is employed as a emulsifying agent and a plasticiser.
The monomer is (C2H6O2)n and has a molecular weight of 62 g.mol-1.
Sodium Magnesium Silicate and Hydrated Silica
These are used as thickening and binding agents. The compounds have very complex structures based on the SiO42- tetrahedron.
Sodium Lauryl Sulfate
This is used as a strong detergent to help remove stains and foaming agent.
Mr = 265 g.mol-1.

Flavour
This is the favouring agent of the toothpaste. The exact compounds used are unknown.
Cellulose Gum

This is used in conjunction with the silicates as a thickening agent.
Synonyms: Cellulose, carboxy methyl ether; Almolose; Cm Cellulose; Carboxymethyl cellulose ether; CMC; Carmellose; Croscarmellose; Carboxymethyl Cellulose.
Sodium Monofluorophosphate

Sodium monofluorophosphate is a major active ingredient in the product. It acts as a source of fluorine, and hence as an anticaries agent.
Mr = 144 g.mol-1.
Synonyms: Disodium monofluorophosphate; Phosphorofluoridic acid, disodium salt; Sodium fluorophosphate.
Sodium Saccharin
Sodium saccharin is present as an artificial sweetener. This is used in place of sucrose, as it is less harmful to teeth.
Mr = 205 g.mol-1
Synonyms: Saccharin soluble; Sodium saccharin; 1,2-Benzisothiazol-3(2H)-one 1,1-dioxide, sodium salt; artificial sweetening substance gendorf 450; crystallose; dagutan; madhurin; Saxin; sodium 1,2-benzisothiasolin-3-one-1,1-dioxide; sodium o-benzosulfimide; sodium benzosulfimide; sodium saccharide; sodium saccharinate; soluble saccharin; soluble gluside; succaril; Sucra; o-sulfobenzoic acid imide sodium salt; sulfobenzoic imide, sodium salt; sweeta; sykose; willosetten; 1,2-benzisothiazolin-3-one, 1,1-dioxide, sodium salt; Sodium 1,2-benzothiazol-3-on-2-ide 1,1-dioxide; o-Benzoic sulfimide sodium salt dihydrate.
Calcium Glycerophosphate

Mr = 210
Synonyms: 1,2,3-Propanetriol, mono(dihydrogen phosphate), calcium salt (1:1).
Sodium Hydroxide
Sodium hydroxide acts as a base, to neutralise the low pH conditions produced by plaque bacteria and to enable their easy removal.
Mr = 40 g.mol-1
Synonyms: Caustic soda; Sodium hydrate; soda lye; Lye; White Caustic; lye, caustic; Augus Hot Rod.
Sodium Fluoride
Sodium fluoride is another active ingredient. Like sodium monofluorophosphate it acts as a source of fluorine, and hence as an anticaries agent.
Mr = 42 g.mol-1
Cl 77891, Cl 73360 and Cl 42090
These compounds have unknown structure, but are assumed to be colouring agents, to provide the distinctive stripy paste.
