Basic Information
sodium lauryl ether sulfate (AES), chemically known as sodium lauryl ethoxylate sulfate, is a common anionic surfactant. It has excellent detergency, emulsification, foaming properties and hard water resistance, and its mild washing nature will not damage the skin.
Daily Use Field
AES is widely used in the production of daily-use products such as soaps, shower gels, shampoos, facial cleansers, cosmetics and skin care products due to its low production cost and high emulsifying and foaming properties.
Industrial field
In the industrial field, AES can be used for metal cleaning, textile processing and lawn maintenance.
Safety and possible side effects
Despite the many excellent properties of sodium dodecyl ether sulfate, there are concerns about its safety. Studies have shown that high concentrations of SLS may be irritating to the skin and eyes, and prolonged exposure may lead to dryness and sensitization of the skin. Therefore, SLS-containing products should be used in moderation and care should be taken to avoid contact with the eyes.
Preparation Methods
Preparation of AES is generally obtained by etherification reaction. Dodecanol reacts with ethylene oxide to form dodecyl ether; then, dodecyl ether reacts with sulfur trioxide to produce AES.
Precautions for use
Individuals may be allergic to AES and its use may cause skin irritation and discomfort. If discomfort occurs, discontinue use immediately. When preparing and using AES, it is necessary to observe the relevant safety operating procedures and avoid direct contact with skin and eyes.
Environmental and ecological effects
AES is biodegradable in the environment, but its impact on the environment needs to be further studied and evaluated. The potential effects on aquatic ecosystems and soil microorganisms should be considered when using products containing AES.
In summary, sodium dodecyl ether sulfate (AES) is an important surfactant widely used in many fields. However, its use is also accompanied by certain risks, so it needs to be handled carefully in practical applications.
