WebBuffers do so by being composed of certain pairs of solutes: either a weak acid plus a salt derived from that weak acid or a weak base plus a salt of that weak base. For example, a buffer can be composed of dissolved acetic acid (HC 2 H 3 O 2, a weak acid) and sodium acetate (NaC 2 H 3 O 2, a salt derived from that acid). WebIn shampoos. Many shampoos use a citric acid/sodium citrate shampoo to maintain a slightly acidic "pH balance". This counteracts the basicity of the detergents present in the shampoo. In baby lotions. Baby lotions are buffered to a pH of about 6. This hinders the growth of bacteria within the diaper and helps prevent diaper rash.
