Sodium lauroyl lactylate is a multifunctional ingredient that has gained popularity in the skincare industry due to its versatile properties. As an anionic surfactant, it possesses both hydrophilic and lipophilic components, allowing it to effectively bridge the gap between oil and water-based ingredients in formulations [1]. This property makes it an excellent emulsifier, helping to create stable and homogeneous products.

One of the key benefits of sodium lauroyl lactylate is its ability to enhance skin hydration. Studies have shown that it can increase the moisture content of the stratum corneum, the outermost layer of the skin, by up to 40% [2]. This moisturizing effect is attributed to its ability to form a protective film on the skin surface, reducing transepidermal water loss (TEWL) and helping to maintain skin hydration levels.

Furthermore, sodium lauroyl lactylate has been found to have mild antimicrobial properties, which can be beneficial in maintaining the skin's natural microbiome balance [3]. Its gentle cleansing action helps remove impurities without stripping the skin of its natural oils, making it suitable for use in a wide range of skincare products, including those formulated for sensitive skin types.
