Definitions
- R 1 and R 2 independently of one another are C1-4 (OCaHUjx (OCsHejy, the (OC2H4) groups and the (OC3H6) groups are arranged block-wise
- Oral care composition for the purposes of the present invention means a paste, powder, liquid, gum, serum or other preparation for cleaning the teeth or other surfaces in the oral cavity.
- composition of the invention preferably includes a phosphate compound.
- Phosphate compounds which may be included in the composition are one of more of
- the phosphate compound is preferably included in 0.1 to 5%, more preferably 0.1 to 3% by weight of the composition.
- the weight ratio of the polymer to the phosphate compound is preferably in the range of 1 : 1 to 5: 1 , more preferably in the range of 2: 1 to 4:1.
- phosphate compound e.g. hexametaphosphate
- HAP hydroxyapatite
- the polymer on the other hand adsorbs on the surface of the HAP and reduces the surface energy by way of the hydrophobic segments of the polymer sitting on the HAP surface while the hydrophilic segments (PEG) protrude out like a brush repelling any stain (e..g. polyphenol molecules) that approach the HAP surface.
- the two actives viz. the phosphate compound and the polymer when used in combination complement each other and thus provide enhanced stain prevention.
- the oral care composition of the present invention may be delivered in the form of an ointment, a gel, a dentifrice or a mouthwash.
- Dentifrices include forms like toothpaste and toothpowder.
- a composition is most preferably presented in the form of a toothpaste, a toothpowder or a mouthwash.
- the low refractive index silicas used as abrasives in the present invention are preferably silicas with an apparent refractive index (Rl) in the range of 1.41 to 1.47, preferably 1.435 to 1.445 , preferably having a weight mean particle size of between 5 and 15 m , a BET (nitrogen) surface area of between 10 and 100 m 2 /g and an oil absorption of about 70 - 150 cm 3 /100 g, but abrasive silicas with a lower apparent refractive index may also be used .
- Rl apparent refractive index
- BET nitrogen
- the composition comprises a thickener.
- Thickeners that may be used in this invention include, sodium carboxymethyl cellulose (SCMC), hydroxyl ethyl cellulose, methyl cellulose, ethyl cellulose, gum tragacanth, gum arabic, gum karaya, xanthan gum, sodium alginate, carrageenan gum, guar gum, Irish moss, starch, modified starch, silica based thickeners including silica aerogels, magnesium aluminum silicate (e.g., Veegum), Carbomers (cross-linked acrylates) and mixtures thereof.
