We supply buffer solution pH 7, pH 9, pH 9.2 and pH 10, as well as ammonia buffer solution. In addition, all our products come with further options, including customised labelling and specific pack sizes.

What is a Buffering Agent?

A buffering agent, which can be either a weak acid or a weak base, can resist pH changes when bases or acids are added. These buffering agents are usually dissolved in water to make buffering solutions.

The way these buffering agents restrict pH changes can be demonstrated by comparing how buffered and non-buffered solutions react to the addition of acids or bases. In chemical terms, these solutions work by establishing an equilibrium between the acid and its respective conjugated base. The concentration of the acid and salt can vary, but their ratio (in log form) remains stable.

Examples of Buffering Agents

Monopotassium phosphate (MPK) is a buffering agent often used in the manufacture of fertiliser, it limits pH changes avoiding nitrogen losses and also works as a source of potassium

There are many buffering agents in the body to ensure that metabolic reactions occur within their preferred pH range. Examples include bicarbonate and ammonia, as well as some proteins and phosphate.

Many cosmetic and personal hygiene products are buffered to ensure they stay slightly acidic. If these products turn too acidic or too alkaline they could damage skin and hair.

About Buffer Solutions

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.
