Citric Acid is found in a variety of fruits and vegetables, but it is most concentrated in lemons and limes, where it can comprise as much as 8% of the dry weight of the fruit.
Citric acid is also the most widely used organic acidulate, probably because it is classified as a weak acid. As with all manufacturing processes, we recommend lab scale trials in order to determine appropriate quantities. Normally the product is titrated with a dilute solution of Citric Acid (10 or 20% in water) until the desired pH is achieved.
Citric Acid is an Alpha-Hydroxy Acid and hence will have some exfoliant properties, although these are much weaker than Glycolic, Lactic and Malic Acids.
In biochemistry it is important as an intermediate in the citric acid cycle and, therefore, occurs in the metabolism of almost all living things. It also acts as an antioxidant.
Origin: Naturally derived through fermentation of corn.
Manufacturing Tips: To make a 20% Solution of Citric Acid measure out 80g of water and to that add 20g of citric acid and stir. The citric will dissolve in readily without heating and citric solutions require no preservative due to the low resting pH (less than 2).
