Description

Detergent preparations containing dimethicones with polyether chains

Technical field

The present invention relates to detergent compositions, and in particular to those compositions used for cleaning dentures and the like. In particular, the present invention relates to improved actions against which at the same time are further characterized by excellent solubility properties, efficiency in use.

detergent compositions with dental coating, cleansing properties, and physical properties, antibacterial efficacy and

BACKGROUND OF THE INVENTION

Effervescent tablets and powders are well known dentifrice cleansing compositions. The purpose of dentifrice cleaning compositions is to clean the dentures as best and as quickly as possible and, in particular, to remove the coating on the teeth which is formed by deposits of slime and bacteria residues that have formed while the dentures have been worn. Wearing dental prostheses that are not perfectly cleaned of coatings and bacteria is not only unhygienic, but can also have a significant adverse effect on the mucosa over a short period of time, resulting in a corresponding discoloration and odor formation.

Silicones are used in dental care compositions, in particular to form a film on the surface, prevent tooth decay and color the teeth. For example, GB-A-689,679 discloses dental water which contains organopolysiloxane to aid in the removal of dirt, discoloration, tartar and food debris from the teeth.

US-A-2 806 814 discloses dental care compositions comprising a combination of a higher aliphatic amino acid amide as active ingredient and a silicone compound. The patent discloses that silicone compounds are present to accelerate the removal of dirt, stains, tartar, and the like from teeth.

According to the patent, the silicone compound is intended to have synergistic effects promoting the enhancement of antimicrobial activity and the ability to reduce the acidity of the active ingredient. Dimethyl polysiloxanes are particularly effective.

US-A-3624120 discloses quaternary ammonium salts of cyclic siloxane polymers as compounds which are used as cationic surfactants, bactericides and as anticariogenic agents.

However, dental prostheses are made of plastics such as acrylates, and the problem of preventing the formation of coatings from these dental prostheses is therefore fundamentally different from the problem of coating and removing them from enamel.

Accordingly, the present invention provides a dentifrice composition which is characterized by considerable activity in protecting against the formation of coatings, slime and bacterial deposits, and at the same time having excellent cleaning performance, excellent appearance, physical and dissolution properties, antibacterial and in-use performance .

SUMMARY OF THE INVENTION
