Abstract
A flavored toothpaste composition is bonded to the bristles of a disposable toothbrush by a process which involves the chemical grafting and polymerizing of selected monomers and prepolymers to the bristles via a free radical mechanism. This process locks in the flavor until the product can be utilized. When the toothpaste is brought into contact with an aqueous medium, such as saliva in the oral cavity, the toothpaste dissolves thereby releasing the desired flavor to the teeth and oral cavity.
Claims32
A method of bonding a flavored toothpaste composition to a substrate, comprising the steps of:
- (a) providing a toothbrush having bristles comprising said substrate;
- (b) activating the substrate with a graft initiator;
- (c) bonding a monomer/prepolymer to the activated substrate;
- (d) polymerizing the monomer/prepolymer to form a graft polymer chain;
- (e) chemically bonding a flavoring to the polymer chain, steps (b) through (e) being performed in the presence of a catalyst;
- and
- (f) drying the toothbrush containing the flavored toothpaste composition to complete the graft polymerization whereby the flavoring is preserved until the toothbrush and flavored toothpaste composition is utilized.
A method of bonding a flavored toothpaste composition to a substrate, the substrate being the bristles of a toothbrush, comprising the steps of:
- (a) applying a single coat of the toothpaste composition to the bristles of the toothbrush, the single coat including a monomer/prepolymer, a catalyst, a graft initiator, flavoring and other auxiliary excipients;
- and
- (b) air drying the toothbrush containing the flavored toothpaste composition.
