Sodium lactate is the sodium salt of lactic acid, and has keratolitic properties. It is produced by fermentation of a sugar source, such as corn or beets, and then, by neutralising the resulting lactic acid.
Sodium Lactate is one of the Natural Moisturising Factors (NMF) constituent of skin, required in the maintenance of natural hydration. Sodium Lactate is a superior moisturiser, increasing the moisture content of skin by up to 84%. When compared to other commonly used moisturisers, it’s water holding capacity is second only to Hyaluronic Acid. Sodium Lactate effectively forces cells to hold water.
We incorporated sodium lactate in the formula for its buffering properties. It works in synergy to our cleansers that contain acids. The sodium lactate neutralises eventual free acids left on the skin surface after using all-in-one cleanser or micellar water.
A slightly alkaline pH in toning lotions is also interesting because it produces the swelling of corneocytes. The penetration of products and treatments applied subsequently is highly enhanced.
