Oral care composition

A method for altering the bacterial composition of an oral biofilm such that the proportion of microorganisms detrimental to oral health is reduced while the proportion of health-promoting microorganisms is increased, the method comprising:

• treating an oral biofilm with an oral composition comprising:
• i) a compound in accordance with formula 1 or salt thereof
• wherein the compound in accordance with formula 1 satisfies the following parameters:
• m=0, 1, 2, or 3,
• p=0, 1 or 2,
• n=0, 1, or 2, and
• wherein if n=1 or 2 then R1 and R2 each denote H or together form a further chemical bond,
• if m=1, 2, or 3 then each X, independently of the other, denotes OH, Oalkyl, or Oacyl,
• if p=1 or 2 then each Y, independently of the other, denotes OH, Oalkyl or Oacyl,
• E=H or denotes a radical —COOR3,
• R3═H or alkyl, in which R3═H also for the corresponding salts, and
• ii) a suitable carrier.
