Sodium lauryl ether sulphate, or SLES, is an anionic surfactant widely used in rinse-off products as a primary surfactant. It's excellent at detergency, emulsification, and foamability.

SLES is a very effective foaming agent and an anionic detergent and surfactant found in many personal care products, such as soaps, shampoos, and toothpaste. This makes it a popular choice for its cleansing and emulsifying properties.

SLES is also used in wetting agent formulations, liquid detergents, cleaners, shampoos, and laundry detergents. It's a surfactant that dissolves readily in hard and soft water and provides a consistent foam character.

SLES is an inexpensive and very effective foaming agent. It behaves similarly to soap and is widely used as a foaming agent and wetting agent.

Here are some key characteristics of SLES:

Sodium lauryl ether sulphate is a versatile ingredient with some impressive properties.

It's hygroscopic, meaning it absorbs moisture from the air, so it's best stored in a refrigerator under an inert atmosphere. This property also makes it slightly soluble in water.

The product has good solvency, which is essential for its ability to effectively clean and emulsify. Its favorable hard-water resistance ensures it works well in a variety of conditions.

Here are some key properties of sodium lauryl ether sulphate:

It's also worth noting that sodium lauryl ether sulphate has excellent solubility and compatibility with other surfactants, making it a great choice for formulating a wide range of products.

Sodium lauryl ether sulfate is a gel-like substance that's hygroscopic, meaning it absorbs moisture from the air. This property requires it to be stored in a refrigerator under an inert atmosphere to maintain its stability.

The substance is slightly soluble in water, but it can be dissolved in chloroform and methanol, albeit sparingly. This limited solubility might affect its use in certain applications.

In its gel form, sodium lauryl ether sulfate is colourless to off-white, which is a characteristic property that can be observed visually. The exact shade may vary depending on the specific formulation.

This substance is hygroscopic, which can affect its stability and performance. It's essential to consider this property when handling or storing sodium lauryl ether sulfate.

Here are some key physical properties of sodium lauryl ether sulfate at a glance:

One of the standout features of Sodium Lauryl Sulphate is its excellent solubility and compatibility with other surfactants, making it a great choice for formulating a wide range of products.

Its mild and low irritation properties make it perfect for formulating skin-touch products like Shampoo, Body Lotion, Facial Cleanser, and Hand Soap Liquid.

Sodium Lauryl Sulphate has significant foaming, emulsifying, and cleansing ability, making it a valuable ingredient in many personal care products.

It also has a good hard water resistant property, which is a major advantage in areas with hard water.

Here are some of the key benefits of Sodium Lauryl Sulphate:

It's also worth noting that Sodium Lauryl Sulphate is made from natural coconut extract and has an excellent degradation rate of up to 92%, making it an eco-friendly option.

Sodium lauryl ether sulphate is produced through a multi-step process involving sulfation and neutralization. The sulfation step occurs at a temperature of 25-30°C under a vacuum for about 2.5 hours.

The sulfation reaction is carried out in a glass-lined reactor with chlorosulfonic acid being gradually added to the lauryl ethoxylate. A by-product of the reaction is gaseous HCl.

The sulfation product is then fed to a neutralization vessel where it is contacted with a 50 wt% caustic soda solution to adjust its active component. This step is carried out below 45°C.

The resulting product is a 70 wt% sodium lauryl ether sulfate. Yeser Chemicals, a leading manufacturer of SLES, uses a state-of-the-art production process to produce this product.

The company has a production capacity of 10,000 MT per month and can supply top-quality SLES 70% at a competitive price. The 70% grade is the most commonly used globally due to its higher concentration and cost-effectiveness for transportation.

The production process involves multiple steps, including sulfation, neutralization, and scrubbing. The scrubbing step involves absorbing the HCl by-product in process water to generate a 33 wt% hydrochloric acid solution.

Yeser Chemicals offers three packaging options for SLES: 170 kg drum packing, 220 kg drum packing, and 1000KG IBC tank packing.

Sodium lauryl ether sulphate is a versatile ingredient with a wide range of uses.

It's perfect for formulating skin-touch products like shampoo, body lotion, facial cleanser, and hand soap liquid due to its mild and low irritation properties.

You can also use it to make effective lip balms that hydrate and moisturize dry, chapped lips.

Its significant foaming, emulsifying, and cleansing ability make it a great choice for bubble bath products that clean, degrease, and hydrate the skin.

Sodium lauryl ether sulphate is also suitable for all skin types, making it a great option for face cleansers that treat chapped, flaky, dry, and dehydrated skin.

It's worth noting that it's made from natural coconut extract, with an excellent degradation rate of up to 92%.

Here are some specific product ideas that utilize sodium lauryl ether sulphate:

Sodium lauryl ether sulfate can irritate eyes, skin, and lungs, especially with long-term use.

The International Agency for Research on Cancer has classified ethylene oxide, a contaminant of sodium lauryl ether sulfate, as a known human carcinogen.

Sodium lauryl ether sulfate may be contaminated with measurable amounts of ethylene oxide and 1,4-dioxane, which is a possible human carcinogen and can also harm the nervous system.

1,4-dioxane is a persistent substance that doesn't easily degrade and can remain in the environment long after it's rinsed down the shower drain.

It's worth noting that there is no easy way for consumers to know whether products containing sodium lauryl ether sulfate have undergone vacuum stripping, a process that can remove 1,4-dioxane from cosmetics during manufacturing.

Sodium lauryl ether sulfate (SLES) can irritate eyes, skin, and lungs, especially with long-term use.

It's worth noting that some people may be more sensitive to these irritations than others.

SLES may also be contaminated with a substance called 1,4-dioxane, which is known to cause cancer in laboratory animals.

This contamination occurs during the manufacturing process, and it's not always easy to tell if a product has been affected.

The International Agency for Research on Cancer has classified ethylene oxide, another potential contaminant of SLES, as a known human carcinogen.

This means that prolonged exposure to SLES may pose a risk to human health, particularly in people who use it regularly.

The recommended dosage of Sodium Lauryl Ether Sulfate in detergents, personal care products, and cosmetics is 5.0%-18.0%. This range is crucial to ensure the product's effectiveness while minimizing potential risks.

In general, following the recommended dosage guidelines is essential for safe usage.
