pH Corrector – Liquid Lactic Acid

Use as an ingredient in your preparations:

• To acidify hair care products, particularly conditioning formulas containing Conditioner Emulsifier

• To acidify foaming products, especially those based on Sugar Foam and/or Foaming Base Consistency, surfactants which tend to increase pH

• To correct the pH of cosmetic products that are too alkaline, particularly those containing stabilised vitamin C (which can raise the pH of formulations)

The necessary pH adjustment will generally be minimal (little difference between the pH measured at the end of the formulation and the target pH), so it is essential to add lactic acid in very small doses to avoid ending up with a pH that is too low.

• For a large quantity of product (≥ 100 g), you can add pure lactic acid drop by drop, carefully checking the pH after each addition.

• For smaller quantities of product, we recommend pre-diluting the lactic acid to 50% in order to measure it more accurately:

  • In a clean bottle equipped with a dropper, mix equal quantities of mineral water and lactic acid (for example, 1 ml of lactic acid + 1 ml of water). Shake to mix.

  • Use this dilution to acidify your preparation, adding it drop by drop and checking the pH after each addition.

Lactic acid can be used to lower the pH of all your water-based formulas: shampoos, conditioners, creams, milks, lotions, gels, etc.
