616 results about "Dentifrice" patented technology

Dentifrices, including toothpowder and toothpaste, are agents used along with a toothbrush to clean and polish natural teeth. They are supplied in paste, powder, gel or liquid form. Many dentifrices have been produced over the years, some focusing on marketing strategies to sell products, such as offering whitening capabilities. The most essential dentifrice recommended by dentists is toothpaste which is used in conjunction with a toothbrush to help remove food debris and dental plaque. Dentifrice is also the French word for toothpaste.

Electromagnetic radiation emitting toothbrush and dentifrice system

A cleaning and whitening system for teeth having an electromagnetic radiation emitting toothbrush and a dentifrice with a photosensitive agent is disclosed. The toothbrush has a cleaning surface, such as bristles. The toothbrush is also adapted to direct electromagnetic radiation toward the cleaning surface. The electromagnetic radiation may be monochromatic or polychromatic. Further, the electromagnetic radiation may be substantially free of ultraviolet radiation. Additionally, the electromagnetic radiation may consist essentially of wavelengths within a range of 300 to 750 nanometers. The photosensitive agent is dispersed throughout the dentifrice. The dentifrice transmits the electromagnetic radiation through a varying thickness disposed over a target surface during use of the system. As a result, a significant portion of the photosensitive agent reacts, resulting in whitening stains, removing and / or disclosing undesired substances, and / or foaming. The dentifrice may be clear and may have clear abrasive particles. A method for tuning the cleaning and whitening system for teeth includes formulating the dentifrice with photosensitive agents that react to a range of electromagnetic radiation and providing a toothbrush that emits that electromagnetic radiation range. Another method of tuning the cleaning and whitening system includes designing a toothbrush that emits a range of electromagnetic radiation and formulating a dentifrice with photosensitive agents that react to the electromagnetic radiation range.

Toothbrush for massaging and protecting gums

This invention relates to a toothbrush that utilizes a replaceable brush head having rubber gum guard on its top surface and a triangular shaped rubber pad on its bottom surface. The rubber gum guard is shorter than the height of the bristles and is positioned on the peripheral edge of a brush head for functioning as a sensor for providing feedback to prevent brushing at excessive pressures and improper angles as well as for massaging the gumlines without the risk of gum damages. The triangular shaped rubber pad is for conforming to and massaging gumlines at the back of teeth. The replaceable brush head having the rubber gum guard and massaging pad features is economically used in conjunction with a permanent handle that dispenses dentifrice material to the top of bristles. The handle has a resilient contractible connector for secure mounting of the replaceable brush head.

Oral Care Compositions

Disclosed are oral care compositions, particularly thickened dentifrices in liquid, paste or gel form comprising a binding / thickening system that also function effectively as humectant agent thereby replacing a significant portion or all of traditional humectant components such as glycerin, sorbitol and other polyols. The binding / thickening system comprise select carrageenans that provide a water viscosity of at least about 20 mPa·s in a 1.5% solution at 25° C. and effective water-binding capacity to prevent significant water loss from the composition when exposed to air to cause unacceptable drying out. For example, the water-binding capacity of the carrageenan must be effective such that there is no more than about 0.75% water loss from a dentifrice composition when exposed to air for 30 minutes at room temperature conditions and 50% relative humidity. The present dentifrice compositions exhibit increased dispersibility in saliva during use, which provides for increased contact time of the composition with the user's teeth and oral cavity tissues such that the active dental agents contained therein are more rapidly available to effect their beneficial activity.

Classified silica for improved cleaning and abrasion in dentifrices

A method of making precipitated silica abrasive compositions having excellent cleaning performance and lower abrasiveness with post-reactor sizing of the abrasive particles being performed via air classification techniques is provided. By targeting a specific particle size range, it has been determined that higher pellicle film cleaning levels may be achieved without also increasing the dentin abrasion properties of the silica products themselves. As a result, dentifrices including such classified abrasive silica products, and exhibiting particularly desirable cleaning benefits, can be provided for improved tooth polishing, whitening, and the like, without deleteriously affecting the hard tooth surfaces. Also encompassed within this invention also are products of this selective process scheme and dentifrices containing such classified silica products.

Delivery system for dental agents

InactiveUS6139820AIncreased volume-to-mass ratioLimiting and dangerousCosmetic preparationsToilet preparationsToothpasteBULK ACTIVE INGREDIENT
Toothpaste and other dentifrices formulated to include a volume increasing agent (density reducing agent) in order to significantly increase the volume of the toothpaste at the time it is dispensed onto a toothbrush. The inventive dental compositions preferably include a substantial quantity of entrained or trapped air or other gas in order to reduce the density, and hence the weight, of toothpaste actually placed within a person's mouth. The result is a reduction in the amount of active ingredients introduced into a person's mouth that might be ingested. The entrained air or other gas can also increase the availability of the active ingredient since the foamed composition increases the dispersibility of the active ingredients within saliva. The net effect is that a person decreases the actual amount of toothpaste without decreasing the volume, or visual amount, of toothpaste dispensed on the toothbrush. The density-reduction effect can alternatively be provided by means of a lower density filler in addition to, or instead of, the entrained gas. Such fillers typically include trapped air or voids.
