Sodium Lauryl Polyoxyethylene Ether Sulfate CAS 9004-82-4

SLES is a core component in detergent formulations, responsible for the primary cleaning and decontamination duties. The polyoxyethylene ether chain segment and sodium sulfate group in its molecule make it have good water solubility and surface activity, which can significantly reduce the surface tension of water, so that dirt such as oil stains can be more easily dispersed in water to form lotion, which can be cleaned and removed.

In household detergents such as laundry detergent and laundry powder, the addition of SLES not only improves the cleaning ability, but also enhances the product's resistance to hard water, allowing the detergent to maintain good cleaning effect under hard water conditions. In addition, SLES has a high viscosity and can also play a thickening role in the formula, improving the product's user experience.

Shampoo: SLES is a key ingredient in shampoo, with strong stain removal ability that can effectively remove oil, dirt, and residual styling products from the scalp and hair. At the same time, SLES can produce rich and delicate foam, improving the cleaning experience during use. In shampoo, the concentration of SLES is usually carefully formulated to ensure that natural oils are not excessively removed from hair while cleaning it, making hair smoother and easier to comb after washing.
Body wash: SLES also plays an important role in body wash. It can gently clean the skin, remove dirt and excess oil from the surface of the skin, while leaving a certain moisturizing sensation on the skin.

SLES foam is rich and delicate, and the skin feels fresh and relaxed after use. It is suitable for people with various skin types.

Hand sanitizer: Adding SLES to hand sanitizer can enhance its ability to remove dirt and kill bacteria. In public places or homes, using hand sanitizer containing SLES can effectively remove bacteria and viruses from hands and prevent the spread of diseases. At the same time, SLES has rich foam and is easy to use, which is deeply loved by consumers.

In addition to the aforementioned cleaning products, SLES is also used as an emulsifier or thickener in certain cosmetics. For example, in some cream based cosmetics, SLES can help better mix the oil and water phases to form a stable emulsion, improving the stability and effectiveness of the product. However, due to the irritant nature of SLES, caution should be exercised when using cosmetics containing SLES for individuals with sensitive skin, and it is best to undergo skin testing first.

In the textile industry, SLES is widely used as a textile additive in various processes such as pre-treatment, dyeing, and finishing of fabrics.

Pre treatment: During the fabric pre-treatment process, SLES can help remove grease, impurities, etc. from the fabric, improve its whiteness and water absorption, and lay a good foundation for subsequent dyeing and finishing processes.

Dyeing: During the dyeing process, SLES is used as a leveling agent and dyeing aid to ensure that the dye is evenly dispersed and adheres to the fabric, improving the uniformity and fastness of dyeing. Meanwhile, SLES can also reduce static electricity during the dyeing process and improve production efficiency.
Post finishing: During the post finishing process of fabrics, SLES can be used as a softener to make the fabric softer, smoother, and improve wearing comfort.

In the paint industry, SLES is used as a pigment dispersant to evenly disperse pigments in the paint system, prevent pigment precipitation and agglomeration, and ensure the quality and effectiveness of the paint. Meanwhile, SLES can also improve the flowability and coating properties of coatings, making them easier to apply and dry.

In the paper industry, SLES has applications in paper de ink and enhancing paper strength. During the process of paper de ink, SLES can break the adhesion between ink and paper, making it easier for ink to separate from the paper and improving de ink efficiency. In addition, SLES can also be used as a paper reinforcement agent to enhance the strength and durability of paper by binding with cellulose molecules in the paper.

In the process of oil extraction, SLES is used as a drilling fluid additive to reduce the surface tension of the drilling fluid, improve its lubricity and sand carrying capacity, reduce friction and wear during drilling, and protect the drill bit and drill pipe. Meanwhile, SLES can also be used as an oil displacement agent to improve oil recovery by altering the properties of the oil-water interface.

During leather processing, SLES is used as a degreaser and cleaner to remove oil and dirt from the surface of leather, improving its cleanliness and softness. At the same time, SLES can also be used as an emulsifier for leather fatliquoring agents, helping the fatliquoring agents penetrate better into the interior of the leather, improving its moisture and durability.

In the field of mechanical cleaning, SLES is used as a cleaning agent to remove oil and impurities from the surface of mechanical parts, improving their cleanliness and service life. At the same time, SLES foam is rich and delicate, which can penetrate into the gaps of mechanical parts to completely remove dirt.

With the increasing awareness of environmental protection, the application of SLES in the field of environmental protection is gradually increasing. Due to its good biodegradability, SLES can partially replace traditional surfactants, reduce the use of phosphates in detergents, and lower environmental pollution. At the same time, SLES can also be used as a sewage treatment agent, which destroys the binding force between oil stains and suspended solids in sewage, making it easier to separate and remove pollutants, and improving sewage treatment efficiency.
