Sodium Caproyl Lactylate
What is Sodium Caproyl Lactylate?
Sodium caproyl lactylate is the sodium salt of caproyl lactylic acid, an ester formed from lactic acid and caproic acid, a medium-chain fatty acid. This anionic compound serves as a versatile ingredient in rinse-off cleansers like facial washes, shampoos, and body washes, as well as leave-on products such as lotions and creams. It functions by reducing surface tension at the interface between water and oils, enabling effective removal of dirt, sebum, and makeup without stripping the skin's natural moisture barrier. As an emulsifying agent, it forms a protective film around oil droplets dispersed in water, promoting uniform texture and preventing phase separation for long-lasting product stability. Its biodegradable nature and mild profile make it a preferred choice in modern, gentle formulations targeting everyday cleansing and moisturizing needs.
