Abstract
Tooth-imparting whiteness to fluids comprising a particulate whiteness-imparting particles such as hydroxyapatite and an organosiloxane polymer are disclosed. Methods of use of the fluids are also disclosed.
Claims2
The method of imparting whiteness to a tooth, comprising applying to the tooth a whiteness-imparting amount of a fluid comprising hydroxyapatite particles and at least one organosiloxane polymer wherein the polymer has a Chemical Abstracts Service Registry Number of 248935-80-0.
The method of imparting whiteness to a tooth, comprising applying to the tooth a whiteness-imparting amount of a fluid comprising hydroxyapatite particles and at least one organosiloxane polymer wherein the polymer is of the formula
- X—[SiR1R2—O—]n-Z
- wherein
- R1 and R2 is each independently an alkyl, aryl, or alkoxy group comprising from 1 to about 40 carbons;
- n is an integer of 1 to 200;
- and
- X and Z are each an organic substituent, one or both of which confers hydrophilicity to the polymer.
