example

[0151] The following examples and descriptions further illustrate embodiments within the scope of the present invention. These examples are given for illustrative purposes only and should not be construed as limitations of the invention, as many changes may be made therein without departing from the spirit and scope of the invention.

example 1

[0153] Examples 1A-1E are dentifrice compositions that may be suitable for preparation by conventional methods selected by the formulator, and illustrate dentifrice compositions comprising polymethylsilsesquioxane particles according to the present invention and fluoride. PCR and RDA values ​​for each formulation were determined using the methods disclosed herein and are reported in Table 2 for each formulation as follows.

[0154] All of these compositions exhibited good cleaning efficacy.

[0157]

[0158] LANNETTEW is a mixture of cetyl alcohol and stearyl alcohol (50:50) and sodium lauryl sulfate (ratio of about 90:10), commercially available from Cognis / BASF, Germany.

[0159] TOSPEARL materials are commercially available from Momentive (New Jersey, USA).

example 2

[0161] Examples 2F-2K are dentifrice compositions that can be suitably prepared by conventional methods selected by the formulator. Examples 2G to 2J show dentifrice compositions comprising polymethylsilsesquioxane particles according to the present invention. Example 2F is a comparative example that does not contain an abrasive. Example 2K is a comparative example comprising a precipitated silica abrasive commercially available from Huber.

[0162] Table 3 below shows the particle size of the TOSPEARL materials used, as determined using a Malvern 2000 (PS-3 Hydro2000SN; model APA2000) using the method as shown herein.

[0163] PCR values ​​for each formulation were determined using the methods disclosed herein and are reported in Table 4 for each formulation as follows. figure 2 Plots of PCR values ​​for formulations 2F-2K.

[0164] As can be seen from the data below, compositions comprising polymethylsilsesquioxane particles with an average particle size of about 4.2 and...

Abstract

Oral compositions containing a polyorganosilsesquioxane particle, preferably polymethylsilsesquioxane particles and an orally-acceptable carrier. Method of using such compositions for the cleaning and polishing of dental enamel, such methods including the step of applying such oral care compositions to the teeth of a user.

Description

technical field [0001] The present invention relates to oral care compositions comprising abrasives, and methods of using these compositions for cleaning and polishing teeth. Background technique [0002] Effective oral compositions can maintain and protect the appearance of teeth by removing stains and polishing teeth. It also cleans and removes external debris, which can help prevent cavities and promote healthy gums. [0003] Abrasives in oral compositions aid in the removal of the strongly adhering film to which tooth stains adhere. The film typically contains a thin acellular glycoprotein-mucin coating that adheres to the enamel within minutes of tooth cleaning. The presence of various food pigments within the film is responsible for most various tooth discoloration conditions. Effective abrasives remove thin films while minimizing abrasion to oral tissues such as dentin and enamel. [0004] In addition to cleaning, abrasive systems are also expected to provide poli...
