Embodiment Construction

[0024] The toothpaste in the following examples can be produced by heating method or room temperature method. The heating method is produced according to the following steps: (1) Stir with a high-speed stirrer for 10 minutes, and disperse the adhesive in the wetting agent to form a gel. (2) Water was heated to 80°C, added to the wetting agent, and stirred for 15 minutes while maintaining the temperature at 65-70°C. (3) Dry blend sodium saccharin and sodium benzoate. This dry mixture was stirred into the binder slurry and stirred for 15 minutes while maintaining the temperature at 65-70°C. (4) Vacuum the gel (Amaranth) into a low speed Ross mixer. Ross TM The mixer is a well-known double planetary gear, double paddle mixer, the speed of operation is 20-100 rpm, and it can be operated under vacuum. (5) Chalk and optionally some kind of silica are added to the sweet liquor and mixed under vacuum (at least 720mmHg) for 15 minutes. (6) Add fragrance to the balsamic liquor and ...

Abstract

A stable, high moisture boothpaste has now been developed that comprises a carrageenan binder that is at least 70 % iota carrageenan, a calcium based-polish agent, humectant, surfactant, water and optional additives and therapeutic actives used in dentifrice compositions. The calcium-based agent is present at a weight percent concentration in the range of about 35 to 50, the water is about 35 to 50%, the humectant is about 5 to 15 %, the carrageenan is about 0.5 to 0.85 %, and the surfactant is about 0.5 to 5 %. The high moisture, low cost toothpaste that is provided has favorable physical properties such as good viscosity and stability without the need for additional binder which is optional.

Description

[0001] The present invention relates to a stable high moisture content toothpaste composition comprising a carrageenan binder, a calcium-based polish, a humectant, a surfactant, water and an optional additives and therapeutic actives. More particularly, the present invention relates to a stable high moisture content toothpaste in which the polishing agent is 35-50% by weight, the water is 35-50% by weight, and the humectant is 5-15% ( weight), carrageenan is 0.5-0.85% (weight), and at least 70% of the carrageenan content is iota carrageenan. Background of the invention [0002] Toothpaste typically contains the following general ingredients: polishing or abrasive agents, humectants, binders or thickeners, surfactants, and water. Wetting agents and hydrators are combined under excipients. Additionally, substances that provide therapeutic or cosmetic benefits, such as antiseptics, fluoride, flavoring agents, sweetening agents, and tartar inhibitors, may be added. In toothpast...
