The present invention relates to a buffer composition comprising a first and a second buffer component, an article comprising the buffer composition being an aqueous preparation and/or a solid article, a process for buffering an aqueous preparation and a solid article as well as the use of said buffer composition for maintaining the pH of article, preferably an aqueous preparation or a solid article, equal to or below 12.
Claims19
Buffer composition comprising a first and a second buffer component, wherein
- a) the first buffer component is at least one water soluble or water dispersible source of magnesium ions and/or zinc ions, and
- b) the second buffer component is at least one alkali carbonate and/or at least one alkali bicarbonate,
- wherein the molar ratio of the first buffer component to the second buffer component [Mg and/or Zn ions/carbonate and/or bicarbonate ions] is from 10 000:1 to 1:10 000.
