Sodium Lactate 60% is a liquid salt derived from lactic acid, commonly used in personal care formulations as a humectant and skin-conditioning agent. It is a by-product of natural fermentation processes and is often used to hydrate the skin by drawing moisture from the environment into the skin, improving moisture retention and overall skin texture.
In addition to its hydrating benefits, Sodium Lactate 60% also helps to stabilize formulations, enhance product spreadability, and reduce irritation. It is compatible with most types of emulsions and can be used in both skin and hair care products. It also helps to boost the effectiveness of preservatives, making it a valuable ingredient for formulation stability.
It is particularly useful in products designed for dry skin, sensitive skin, or those requiring additional moisture, as it helps maintain skin’s hydration levels and promotes a smooth, soft feel.
