Citric acid is a naturally occurring acid which is found in large quantities in fruits – notably citrus fruits such as oranges, lemons and certain berries. It is a relatively weak acid and has a distinct, sour taste. It is an integral part of the Krebs cycle and therefore plays an essential role in the metabolism of all living things. The acid was first produced from citrus fruits but this technique was inefficient and only produced small quantities. Today, specific strains of the mold. Aspergillus niger are used in the industrial production of the citric acid via a fermentation process. The acid can be found in both liquid and powder (anhydrous) form.
Citric acid: It’s one of the most common food additives found in our food supply today, yet for many of us it remains a mysterious ingredient. In some countries, citric acid has been used as an additive in foods, cosmetics and many other products for more than 100 years, mostly as a preservative and flavor enhancer.
Citric acid is commonly used in food and beverages, detergents, pharmaceuticals, cosmetics, toiletries and other industries.
Uses in cosmetics
Citric Acid helps with pH adjustment
The pH level of skincare formulations is an extremely vital factor deciding both quality and safety. An ideal pH enables products to become more safe, pleasant, and less irritating to use. In addition, the performance of some actives, colorants, thickeners, and other ingredients can also be dependent on the pH level deviations can result in undesired outcomes such as discoloration, changes in viscosity, and poor product performance. If the formula ends up becoming too alkaline, Citric Acid can be added to lower the pH to a desired level.
