Abstract

Oral and dental care and cleaning agents which, based on the weight thereof, contain 1 to 10% by weight sorbitol, 1 to 5% by weight glycerin and 0.1 to 1% by weight xanthan exhibit an optimal compromise between applicability and plaque reduction and fluoride deposition. In addition, these compositions are suitable in particular for cleaning by means of electric toothbrushes, since said compositions are gentle on the sensitive mechanism of the electrically operated brush heads.

Description

"Toothpaste with improved rheology"

The invention relates to a toothpaste having a rheology that promotes plaque reduction and fluoride deposition and also accommodates the particular requirements of using electric toothbrushes.

Dentifrices are available in various forms on the market and are primarily used to clean the tooth surface and to prevent tooth and gum disease. They usually contain a combination of polishes, humectants, surfactants, binders, flavorings and fluoride-containing and antimicrobial agents. In addition to toothpowder, which play a minor role because of their increased abrasiveness, dentifrices are mainly offered in paste, cream and translucent or transparent gel form. Liquid or liquid toothpastes and mouthwashes have also become increasingly important in recent years.

At the same time, developments have also been pursued on the equipment side. In addition to the conventional manual toothbrush, which is moved by the consumer with circular movements in the mouth, electric toothbrushes have become established in the market, which produce a part of the movement of the bristles on the tooth surface by a handpiece located in the - usually rechargeable bare - battery. Depending on the model, the consumer can thus replace the circular hand movement with a horizontal-linear movement.

Electrically moving brush heads are customary in various designs. Thus, there are round brush heads which are electrically rotated in rotation or partial rotation with rotations clockwise and counterclockwise. But there are also elongated, the conventional toothbrush modeled brush heads, which oscillate electrically.

All electric toothbrushes have the advantage in common that they relieve the consumer part of certain movements and have a reputation to clean the teeth more thoroughly. However, these advantages are also faced with disadvantages: An electric toothbrush usually leads to a more intensive load on the tooth surface than when brushing teeth by hand. If the type and content of the abrasive particles in the toothpaste are not adjusted to this, damage to the enamel can occur in conjunction with an electric toothbrush. Another problem is that the complex mechanism in the brush head can be glued and the toothbrush can then no longer perform the corresponding electrical movement. In addition, the rheology must be considered, because on the moving brush heads must be given a certain adhesion to avoid splashing the toothpaste.

Some of the above-mentioned requirements are contradictory, since abrasive particles are at least a part of consistency.

Even when using conventional toothbrushes, the rheology of the dentifrice plays an important role: The composition must be sufficiently viscous to be applied to the brush head, while brushing but they quickly give an application mixture in the oral cavity, the effective PIaquereduzierung and a high Fluoride deposition allows what is usually more effective to realize with low viscosity compositions.

Another area of responsibility is the provision of products that solve the tasks assigned to them with as little raw material as possible, in order to save resources and to provide ecologically compatible products. The reduction of synthetic ingredients is therefore another important task in the formulation of cosmetic products.

The present invention therefore an object of the invention to provide a mouth and Zahnpflege- and -reinigungsmittel that solves the above-mentioned tasks and is sufficiently viscous to be applied to brush heads conventional or electric toothbrushes, but it is sufficiently low viscosity to to allow effective reduction of PIaquer and high fluoride deposition. In addition, the formulations should contain as few synthetic ingredients as possible.

It has now been found that compositions with low humectant levels can be thickened with certain amounts of xanthan so as to achieve an optimum compromise between applicability and piquer reduction and fluoride deposition, respectively. In addition, these compositions are particularly suitable for cleaning by means of electric toothbrushes, as they protect the delicate mechanics of electrically operated brush heads. Preferably, the amounts of certain humectants are selected within narrow limits. The present invention is in a first embodiment, an oral and dental care and cleaning compositions containing - based on its weight - a) 1 to 10 wt .-% sorbitol

The compositions of the invention preferably contain at least one polishing agent. As a polishing agent are in principle all known for toothpastes friction body, in particular those that do not contain calcium ions. Preferably suitable polishing agent components are therefore silicic acids, aluminum hydroxide, aluminum oxide, sodium aluminum silicates, organic polymers or mixtures of such friction bodies.

Calcium containing polishing components such as e.g. However, chalk, calcium pyrophosphate, dicalcium phosphate dihydrate can be present in amounts of up to 5% by weight, based on the total composition.

The total content of polishing agents is preferably in the range of 5 to 50% by weight of the dentifrice. Agents preferred according to the invention contain polishing agents within narrower ranges. Here are preferred oral and Zahnpflege- and - cleaning agent according to the invention characterized in that they 1 to 25 wt .-%, preferably 2.5 to 20% by weight, more preferably 5 to 18 wt .-% and in particular 7.5 contain up to 16 wt .-% polish. Toothpastes and liquid dentifrices containing silicic acids as a polishing agent are particularly preferred. Suitable silicas are e.g. Gel silicas, hydrogel silicas and precipitated silicas. Gel silicas are prepared by reacting sodium silicate solutions with strong, aqueous mineral acids to form a hydrosol, aging to the hydrogel, washing and drying. If the drying takes place under mild conditions to water contents of 15 to 35 wt .-%, the so-called hydrogel silicas are obtained. Drying to water contents below 15% by weight results in an irreversible shrinkage of the previously loose structure of the hydrogel to the dense structure of the so-called xerogel.

A second, preferably suitable group of silica polishing agents are the precipitated silicas.

Plaque is a rough, sticky deposit on the teeth that consists of saliva, bacteria and food remnants. If mineral salts (for example calcium, phosphate) are released from the saliva in the dental plaque, hard, white or yellowish deposits on the tooth called tartar form. In the porous calculus, in turn, easily deposit plaque that attacks the gums.

The bacteria on the tooth surface reduce carbohydrates, especially sugars, from food to acid. This acid dissolves the tooth substance and it comes to tooth decay (tooth rot).
