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.
