Product Description
Ingredients: L-Lactic Acid, Purified Water
Origin: Our lactic acid is produced via the fermentation of a cultured bacteria via biotechnology.
Solubility: Water. 88% strength.
Lactic Acid is a strong Alpha-Hydroxy Acid and hence will have excellent exfoliant properties, although these are weaker than, but second only to, Glycolic Acid. AHA products can be used as a stand-alone treatment. While AHA can be included in other products there are certain incompatibilities that may arise with AHAs due to their requirement for a low pH.
Lactic Acid products should have a pH of 3.3 to 4.0 for safety while maintaining effectiveness (Note at pH 5.5 AHAs are totally ineffective).
Lactic Acid has a pKa of 3.86 which means at pH 3.86 the solution will contain 50% Lactic Acid and 50% Lactate salt. Reducing the pH by 0.5 pH units to pH 3.36 is enough to shift that equilibrium in favour of the acid and a pH of 2.86 over 90% of the ingredient will exist in acid form.
If you want to use a concentrated AHA then you will find most references suggest Glycolic Acid. However, while this is cheap and obtained in 70% liquid form, because of its apparent activity it has its dangers in that it will quickly burn skin with disastrous consequences. The TGA and the SUSDP (Poisons Committee) have legislated that Glycolic acid at should be used at a maximum of 30% (and preferably no more than 20%) and a pH of greater than 3.5. Otherwise they would be considered therapeutic goods and have various poisons warnings on the label.
In terms of Lactic Acid in-use concentration we suggest working between 5 - 20%.
