A common oral bacteria growth promoter containing (A) a compound represented by structural formula (1) or a salt thereof and (B) a compound represented by structural formula (2) or a salt thereof, wherein the (A)/(B) ratio is preferably 0.1 to 10 by mass; and an oral composition containing the common oral bacteria growth promoter. (In formula (1), one of R 1 and R 2 represents -OH and the other represents -OCOR (wherein R represents a C11-23 hydrocarbon group); and X 1 represents -H, -C 2 H 4 N + (CH 3 ) 3 , -C 2 H 3 (N + H 3 )COOH, -C 2 H 4 N + H 3 , -C 6 H 6 (OH) 5 or -C 2 H 3 (OH)CH 2 (OH).) (In formula (2), R 3 and R 4 independently represent -OCOR 5 (wherein R 5 represents a C11-23 hydrocarbon group); and X 2 represents -H, -C 2 H 4 N + (CH 3 ) 3 , -C 2 H 3 (N + H 3 )COOH, -C 2 H 4 N + H 3 or -C 6 H 6 (OH) 5 .) |
