Embodiment 1

[0020] Ingredient Weight % Functional Ingredient

[0021] Ethanol 79.10 Solvent / preservative

[0022] Eudragit RS 100 10.00 Film former / rheology modifier

[0023] Klucel HF Pharm 00.60 Rheology modifier / film former

[0027] preparation:

[0028] 1. (Optional) Freeze ground Eudragit into powder form to facilitate its dissolution.

[0029] 2. Dissolve Eudragit in ethanol.

[0030] 3. Add Tween 20 to Eudragit solution and disperse TiO in Eudragit solution under high shear conditions (rotor-stator, colloid mill, ball mill) 2 . This can be done before step 1 where the shearing required is detrimental to film formation.

[0031] 4. Disperse the Klucel into the Eudragit solution and mix under moderate shear (marine impeller, etc.). To completely dissolve and expand Klucel.

Abstract

A film forming composition for coating teeth which is a mixture of about 0.5 % to about 30 % by weight of a film forming polymer; about 10 % to about 99.5 % by weight of solvent; about 0.05 % to about 40 % by weight of a rheology modifier; about 0.01 % to about 5 % by weight of a dispersant or plasticizer, if necessary; and optionally up to about 30 % by weight of an opacifier or colorant.

Description

Background of the invention [0001] The present invention relates to a film-forming coating for coating teeth. This is a temporary coating that will eventually wear away or be easily removed when convenient or desired. [0002] Temporary protective coatings or removable protective coatings are known. For example, US Patent No. 5,191,014 to Roberts et al. teaches a temporary protective aqueous coating composition that can be applied to newly finished automotive hydrophobic paintwork and is also easily removed. The composition is a copolymer of (meth)acrylic acid, and a main monomer, which yields a copolymer coating soluble under alkaline conditions with a molecular weight of 10,000-200,000. U.S. Patent No. 5,330,788 to Roberts teaches a temporary coating to protect the surface of an article, which is weather-resistant but soluble under alkaline conditions, and which is a film-forming acrylic class of polymers. US Patent No. 5,916,674 to Skelly et al. discloses an article hav...
