Abstract

The invention concerns a cleaning agent for dental use in the form of a pasty or liquid dispersion, containing between 10 and 30 wt. % of a combination of polishing agents comprising polishing agents based on silicic acid and aluminium oxide in a weight ratio of 10 : (0.2 - 2) and between 20 and 50 wt. % of a moistening agent from the group containing sorbitol, glycerin, propyleneglycol-1,2, polyethyleneglycol and their mixtures, comprising, for reinforcing the cleaning effect, between 2 and 12 wt. % of condensed phosphate from the group comprising tripolyphosphate, pyrophosphate or trimetaphosphate in the form of alkaline salt or ammonium salt. In spite of their low abrasive values, the present inventive cleaning agents have an excellent polishing effect and a high cleaning power.

Description

technical field [0001] The present invention relates to a tooth cleaner in the form of an ointment or fluid aqueous cream containing 10-30% by weight of a polishing composition and 20-50% by weight of a humectant, which is obtained by adding Condensed phosphate further improves its cleaning effectiveness. Background technique [0002] Use a toothbrush and clean your teeth with toothpaste every day. Toothpaste should firstly provide a cleansing of the tooth surface to remove food residues, tooth staining due to, for example, cigarettes or tea, and permanently adherent bacterial-type tooth deposits, known as plaque. This object is mainly achieved by the polishing agents and, to a lesser extent, the surfactants contained in the toothpaste. In order to exhibit its cleaning-and-polishing action, the polish must have a certain abrasive action on the tooth surface. More importantly, the abrasiveness to the enamel and dentin is kept low in order to avoid damage to the tooth surfa...
