Sodium lauroyl lactylate is a naturally-derived ingredient used in skincare products as a surfactant, moisturizer, and emulsifier. It helps improve the functioning of other ingredients, reduces surface tension between liquids, and provides a light foam to products. It also helps remove dirt and oil from the skin, moisturizes, and has antimicrobial properties.
Moisturizes: Sodium lauroyl lactylate helps to moisturize the skin and strengthen the skin barrier, which helps skin to retain water. Antimicrobial: It has antimicrobial effects due to the presence of lauric acid, which is effective for acne-prone skin. Emulsifies: It helps keep oils and waters blended in cosmetic products, improving formulation consistency.
Generally safe for all skin types, unless allergic to lactic acid.
Unlikely to cause significant skin or other issues except in those with a specific allergy to it.
Patch test a new product on a small area of skin first to see how your skin reacts before applying it more broadly.
Sodium lauroyl lactylate is a sodium salt of the reaction of lauric acid and lactic acid. Lauric acid is a saturated fatty acid with a 12-carbon atom chain, which makes it a medium-chain fatty acid. Lactic acid, the other half of the equation, is an alpha-hydroxy acid that is obtained from milk.
Rated as a very low-risk ingredient by the Cosmetic Ingredient Review (CIR).
Rated as a low-risk ingredient by the Environmental Working Group (EWG).
Sodium lauroyl lactylate is a gentler alternative to many other surfactants, making it suitable for sensitive skin. It is also used in products for babies as young as six months. Sodium lauroyl lactylate is also used as a texture enhancer in skincare products. It helps to improve the texture of products, making them feel smoother and more luxurious.
