SLS Sodium Lauryl Sulfate CAS 151-21-3

It is a white powder, or needle-like particles that are readily soluble in water. It has excellent foaming and emulsifying characteristics.

Description of SLS Sodium Lauryl Sulfate ：

Physical properties: Sodium lauryl sulfate is a white or light yellow powder with a slightly pungent odour. It has a high melting point, about 200°C, is easily soluble in water, and has good solubility.

Chemical properties:  Under acidic conditions, it is easy to undergo a hydrolysis reaction to produce lauryl alcohol and corresponding sulfate. Under alkaline conditions, it can form complexes with metal ions.

Solubilization and colloidal ability: Sodium lauryl sulfate has good solubilization and colloidal ability, which can bring other insoluble substances into the solution, thereby increasing its solubility.

Dispersion and stability: Sodium lauryl sulfate can be used as a dispersant and stabilizer to disperse solid particles in the liquid and maintain its stability.

Hard water resistance: Sodium lauryl sulfate has strong hard water resistance to calcium and magnesium ions in hard water and can be used in hard water without forming precipitation.

Technical Parameter SLS Sodium Lauryl Sulfate

Applications of SLS Sodium Lauryl Sulfate:

Personal care products: In personal care products, sodium lauryl sulfate is used as an emulsifier, foaming, and cleaning agent. It can produce a rich, stable foam and improve the product's cleaning ability. At the same time, sodium lauryl sulfate can also promote the removal of oil and dirt on the skin surface, making the skin more refreshing and smooth. Adding sodium lauryl sulfate can improve product performance and user comfort in shampoos, body washes, facial cleansers, and other personal care products.

Cosmetics: In cosmetics, sodium lauryl sulfate is mainly used to produce creams, lotions and facial masks. At the same time, sodium lauryl sulfate can also be used as a wetting agent to improve the moisturizing performance of the product and provide users with a more moisturizing experience. In lipstick, eyeshadow, and other makeup products, sodium lauryl sulfate also has an application that can improve the adhesion and durability of the product.

Laundry and detergent can effectively separate stains and oils from clothes, making clothes cleaner. At the same time, sodium lauryl sulfate can also promote the suspension and dispersion of stains, making it easier to be washed away with water. Adding sodium lauryl sulfate to laundry detergent and detergent can greatly improve clothing cleaning efficiency and washing effect.

Industrial cleaning agents: Sodium lauryl sulfate is also widely used in industrial cleaning agents. It can clean various equipment and surfaces, such as oil, dust and fingerprints. Because sodium lauryl sulfate has a strong penetration, emulsification and dispersion ability, it can effectively remove stubborn stains and impurities, so the equipment and surface restore the original lustre and cleanliness. 

Production Method of SLS Sodium Lauryl Sulfate:

Esterification reaction

Lauryl alcohol and sulfuric acid were esterified to produce lauryl alcohol sulfate. In this step, conditions such as reaction temperature, concentration and catalyst must be controlled to ensure a smooth reaction.

Hydrolysis reaction

Lauryl sulfate was hydrolyzed to produce sodium lauryl sulfate. In this step, conditions such as reaction temperature, concentration and hydrolysis agent must be controlled to obtain high-yield sodium lauryl sulfate.

Separation and purification

The sodium lauryl sulfate in the reaction solution was separated by centrifugation, filtration and drying. Further purification operations, such as recrystallization or ion exchange, are performed to obtain high-purity sodium lauryl sulfate.

Precautions

In producing sodium lauryl sulfate, paying attention to safety issues is necessary. For example, sulfuric acid is highly corrosive and irritating, requiring personal protective equipment such as clothing and goggles. In addition, operations such as centrifugation and filtration involve mechanical operation and require special attention to safe operating procedures.

In addition to the above methods, there are other production methods, such as direct synthesis, transesterification, etc. These methods can be selected and adjusted according to the actual situation when they are implemented.

Environmental Protection and safety

In production, we must pay attention to environmental protection and safety issues. It must comply strictly with national and local environmental regulations and standards to treat and dispose of waste gas, wastewater, and solid waste. At the same time, appropriate safety measures should be taken, such as fire prevention, explosion-proof, anti-poisoning, etc., to ensure the safety and control of the production process.

Quality control and inspection

To ensure product quality, it is necessary to establish a sound quality control and inspection system. Strict quality control and testing of raw materials, intermediates and final products to ensure product quality meets relevant standards and customer requirements.
