In α olefin sulfonated products after adding water, the formation of emulsion mixture, the mixture slowly heated to 50℃ above, to the demulsification layer, take the lower solution; 2) the lower layer solution is standing at room temperature until the solution becomes gray suspension, remove the water in the gray suspension, obtain α olefin sulfonic acid; 3) the α-olefin sulfonate salt reaction, after drying to obtain α-olefin sulfonate.
Frequently Asked Questions
AOS Properties and Applications
Sodium Alpha Olefin Sulfonate (AOS) is a surfactant that is commonly used in various personal care and cleaning products. It is derived from alpha olefins, which are a type of hydrocarbon with a double bond at the alpha position. AOS is produced by sulfonation of alpha olefins followed by neutralization with sodium hydroxide.
AOS is known for its excellent detergency and foaming properties. It is often used as a primary surfactant in shampoos, shower gels, hand soaps, and other personal care products. It helps to cleanse the skin and hair by reducing the surface tension of water, allowing the product to spread more easily and remove dirt and oils.
In addition to personal care products, AOS is also used in household cleaning products such as dishwashing liquids, laundry detergents, and multi-purpose cleaners. Its ability to create stable and abundant foam makes it effective in removing grease, stains, and other types of dirt.
AOS is considered to be mild and gentle on the skin, making it suitable for use in various formulations. It is often used in combination with other surfactants and ingredients to enhance its performance and tailor it to specific applications.
