Sodium dodecyl ether sulfate (SLES) is an excellent anionic surfactant with multiple functions such as decontamination, emulsification, and foaming. The ether bond and sulfuric acid group in its molecular structure endow it with excellent hydrophilicity and lipophilicity balance, which can effectively reduce the liquid surface tension and form a stable and delicate foam. Compared to traditional surfactants, SLES has lower irritation to the skin and eyes, but it is still important to note that high concentrations or prolonged exposure may cause discomfort.
Widely applicable scenarios
In the field of daily chemical cleaning: As the core ingredient of facial cleansers, shampoos, shower gels, and other products, SLES uses its powerful cleaning ability to remove oil and dirt from the skin and hair, while stabilizing its milky structure to enhance the texture of use. In products such as toothpaste and hand sanitizer, their foaming performance significantly enhances the cleaning experience.
Industrial and Manufacturing Fields
Textile printing and dyeing: As a dyeing aid and lubricant, it enhances dye penetration and dyeing uniformity.
Petroleum and leather: used for oil pollution cleaning, degreasing, and industrial lubrication, helping to streamline production processes.
Pharmaceutical preparations: Recently, Hubei Gedian Renfu Pharmaceutical Excipients Company completed the registration of SLES pharmaceutical excipients (registration number F20170000137), and its solubilization and emulsification properties play a key role in tablet disintegration and transdermal administration.
SLES is a flammable chemical, and transportation should avoid high temperatures, open flames, and severe vibrations to ensure complete packaging sealing and prevent dust leakage. The storage environment should be kept dry and ventilated, isolated from oxidants and strong acids and bases.
Precautions for safe use
Personal protection: Wear protective gloves, goggles, and masks during operation to reduce the risk of direct contact.
Emergency response:
Skin contact: Immediately rinse with clean water, remove contaminated clothing, and thoroughly wash.
Eye contact: Rinse continuously for at least 15 minutes and seek medical attention if necessary.
Ingestion: Do not induce vomiting, immediately drink plenty of water and seek medical assistance.
Special populations: Children and pets should avoid contact with concentrated ingredients containing SLES, and household cleaning agents should be stored properly.
Sodium dodecyl ether sulfate has become an indispensable raw material in the fields of daily chemical, pharmaceutical, and industrial industries due to its multifunctional properties. With the expansion of application scenarios, standardizing transportation and strengthening security protection will become the core issues for the sustainable development of the industry.
