Lauryl sulfate

Description:
Lauryl sulfate, also known as dodecyl sulfate, is an anionic surfactant commonly used in various personal care and cleaning products. It is characterized by its long hydrophobic hydrocarbon chain, typically consisting of 12 carbon atoms, which contributes to its surfactant properties. The sulfate group imparts a negative charge, enhancing its ability to interact with water and oils, making it effective in emulsifying and foaming applications. Lauryl sulfate is soluble in water and exhibits good detergency, making it a popular ingredient in shampoos, body washes, and household cleaners. However, it can be irritating to the skin and eyes, leading to concerns about its use in some formulations. Its effectiveness as a surfactant is often balanced with considerations of skin compatibility, prompting manufacturers to explore milder alternatives in sensitive formulations. Overall, lauryl sulfate plays a significant role in the formulation of various consumer products due to its surfactant properties, though its safety profile is an important factor in product development.
