Lactic Acid 90% is natural L(+)-Lactic acid, produced by fermentation from carbohydrates. It can be used to adjust the pH of cosmetic formulations and is particularly suitable for use in rinse-off feminine hygiene products for which the optimal pH is around 4-4.5. L-Lactic Acid can be considered ‘the body's own' Alfa-hydroxy acid (AHA), as it is naturally produced by the body.

By stimulating exfoliation and cell renewal as well as providing moisturization, it provides anti-aging benefits and helps to obtain smoother, younger and brighter looking skin. Compared to other AHAs, L-Lactic Acid has the best therapeutic index (skin renewal versus possible irritation), which makes it the AHA of choice for anti-aging. It is a highly concentrated, purified grade of natural L-Lactic Acid. It is most suitable for skin care products with a high concentration of lactic acid and a pH between 3.5-4.0, necessary to achieve the most potent anti-aging effects.

Please note, active percentage of Lactic Acid is now 90%, and no longer 88%. Please contact Trulux for further information.
