Our buffer solutions are available in a range of pH readings, including pH 4, 7 and 9.2
Buffer solutions are simply aqueous solutions of a weak acid or base with the ability to maintain a stable pH, even when large amounts of a strong base or acid are added. Buffering agents are commonly used in household products, such as dish detergent and washing up liquid, as well as soap and shampoo. Examples of buffering agents include fatty acids, borate, citric acid, sodium triphosphate and silicate. Most cosmetic and personal hygiene products are buffered to maintain a neutral or slightly alkaline pH. This is to eliminate the soap's naturally high pH. The buffer solution prevents the products becoming too acidic or alkaline which could become irritating for the skin.
How Does it Work?
In any solution, acids increase the concentration of H+ while alkalis generate OH- ions. The pH reflects the ratio between these two ions. A buffering solution can absorb the addition of extra H+ or OH- after the addition of an acid or base. This means the relative concentration of H+ and OH- remains stable and the pH does not change. Typically, acidic buffering solutions - such as to maintain pH4 - contain a weak acid and its respective conjugated base. Strong acids are not good buffering agents as these solutions need large amounts of the acid to be present in a non-ionised form. In a similar manner, an alkaline buffering solution is made up with a weak alkali and its respective salt.
