Buffer solutions
The buffer solution prevents the products becoming too acidic or too alkaline, as this could cause skin irritations. For example, soap has a naturally high pH so are typically buffered to a pH of around 5.5, which is the skin’s natural pH. Another example is shampoo.

Overview. A buffering agent can be either a weak acid or weak base. Buffering agents are usually added to water to form a buffer solution, which only slightly changes its pH in response to other acids and bases being combined with it, particularly a strong acid or a strong base.Another example is buffered aspirin which has a buffering agent, such as MgO or CaCO 3, that will help maintain the
Buffer | chemistry | Britannica …a solution is called a buffered solution or, somewhat more colloquially, a buffer. A buffered solution containing various concentrations of acetic acid and acetate ion, for example, can be prepared by mixing solutions of acetic acid and sodium acetate, by partially neutralizing a solution of … ChemTeam: Buffers and the Henderson-Hasselbalch Equation Example #8: Determine the pH of a solution prepared by dissolving 0.35 mole of ammonium chloride in 1.0 L of 0.25 M aqueous ammonia. K b for ammonia equals 1.77 x 10-5. Solution: 1) This is a buffer solution, with a weak base (the ammonia) and the salt of the weak base (the ammonium chloride) in solution at the same time.
