Oral care composition

Abstract

The invention discloses an oral care composition, which is composed of a chelating agent and an antibacterial agent. The chelating agent does not contain phosphorus, the 28-day biodegradation rate isgreater than 60%, and the calcium ion binding rate (pH is 5.5-10, 25 DEG C) is greater than 700mg / g; the iron ion binding rate (pH is 5.5-10, 100 DEG C) is greater than 700mg / g; wherein the chelatingagent is selected from one or more of citrate, L-GLDA, MGDA, IDS and EDDS, and preferably L-GLDA. The antibacterial agent does not contain chlorine and benzene, the 28-day biodegradation rate is larger than 90%, the minimum antibacterial concentration is achieved, and candida albicans (smaller than 50 ppm), streptococcus mutans (smaller than 50 ppm), porphyromonas gingivalis (smaller than 30 ppm)and fusobacterium nucleatum (smaller than 100 ppm) are included; wherein the antibacterial agent is selected from one or more of 1, 2-pentanediol, 1, 2-hexanediol, 1, 2-octanediol and 1, 2-decanediol,and preferably, the antibacterial agent is compounded according to a certain proportion. The chelating agent and the antibacterial agent are environmentally friendly and are compounded according to acertain proportion, the minimum inhibitory concentration of the antibacterial agent can be reduced, and meanwhile the effect of removing exogenous stains is achieved.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to an oral care composition composed of a phosphorus-free chelating agent and a chlorine-free and benzene-free antibacterial agent. [0002] technical background [0003] General oral whitening products are aimed at exogenous coloring. Exogenous stains on teeth are mainly caused by drinking pigmented beverages, eating pigmented foods and smoking. Whitening toothpaste can remove stains on the tooth surface and restore the original color of tooth enamel. There are three main mechanisms of tooth whitening: physical whitening, chemical whitening, and biological whitening. [0004] First, physical whitening is a kind of friction effect. During the brushing process, the abrasive rubs against the tooth surface back and forth under the pressure and driving force of the toothbrush to remove food residues and stains on the tooth surface. If you use an abrasive with too high fricti...
