High Purity Sodium Laurate CAS 629-25-4

Description of Sodium Laurate:

Physical property

Sodium laurate is a white or yellowish crystalline powder with hygroscopic properties. Its melting point is relatively high, about 280-300°C. Sodium laurate is not readily soluble in water but can form a stable solution with water. At room temperature, its solubility is about 30-50g/100g water. Sodium laurate has a higher density than water, about 1.06g/cm³.

Chemical property

Sodium laurate is a strong base and weak acid salt with significant alkalinity. In water, it can be hydrolyzed to produce sodium hydroxide and laurate ions. Sodium laurate reacts with acid to form salt and water, exhibiting typical ionic reaction characteristics.

Surface activity

Sodium laurate is surface active and can reduce the surface tension of the liquid. This characteristic enables it to exhibit excellent emulsification, wetting, and dispersion properties in many applications. For example, in cosmetics, detergents, and coatings, sodium laurate is used as an additive such as emulsifier, wetting agent, and dispersant.


Sodium laurate has good compatibility in the biological field. It is less irritating to human skin and mucous membranes and is widely used as an ingredient in personal care products and cosmetics. In addition, sodium laurate has antibacterial, anti-inflammatory, and other biological activities and can prepare antibacterial agents, anti-inflammatory agents, and other pharmaceutical products.


Sodium laurate is stable at room temperature but may be decomposed or hydrolyzed under high temperatures and strong acid conditions. Under alkaline conditions, sodium laurate can react with some metal ions to form complexes. In addition, sodium laurate also has good oxidation resistance and can resist oxidation reactions to a certain extent.


Sodium laurate is relatively safe for humans and the environment under normal conditions of use. However, overuse or improper use may harm the human body and the environment. Therefore, the use of sodium laurate should follow the relevant regulations and guidelines to ensure its safe use.

Production Method of Sodium Laurate:

Raw material preparation

The raw materials to be prepared for the production of sodium lauric acid include lauric acid and sodium hydroxide or sodium carbonate. Lauric acid can be obtained by hydrogenation of natural oils or by chemical synthesis. Sodium hydroxide or sodium carbonate are usually commercially available reagent-grade products.

Reaction process

In the mixing process, an appropriate amount of water and additives such as catalysts can be added to promote the reaction.

Under heating conditions, lauric acid reacts chemically with sodium hydroxide to form sodium laurate and water or carbon dioxide. The reaction equation is: RCOOH + NaOH → RCOONa + H₂O or RCOOH + Na₂CO₃ → RCOONa + CO₂↑+ H₂O.

Separation and drying

The reaction product is separated to remove unreacted lauric acid and other impurities. It can be separated by precipitation, filtration, centrifugal separation, and other methods. After separation, the sodium laurate precipitate is dried to remove the water or carbon dioxide to obtain a dry sodium laurate product.

Grinding and packing

The dried sodium laurate was ground to make its particle size finer and distribution more uniform. Finally, it is packed for use.

It should be noted that the specific production methods and process parameters may vary according to different manufacturers and product requirements. In the actual production process, it is necessary to adjust and optimize according to the specific situation and pay attention to the control of raw material quality, reaction conditions, product quality, etc., to ensure that the production of sodium laurate meets the requirements and meets the market demand. At the same time, it is also necessary to pay attention to safety issues and environmental protection to ensure the safety and environmental security of the production process.

Applications of Sodium Laurate:

Personal care products

Sodium laurate is widely used in personal care products, such as shampoo, body wash, skincare products, etc. In these products, sodium laurate can be used as an additive such as an emulsifier, wetting agent, and dispersant to help improve the texture and stability of the product while having antibacterial, anti-inflammatory, and other biological activities to help protect skin health.


Sodium laurate is used in cosmetics as an additive such as emulsifier, wetting agent, and dispersant, which can significantly improve the texture and stability of products. At the same time, sodium laurate has antibacterial, anti-inflammatory, and other biological activities that can be used to prepare antibacterial agents, anti-inflammatory agents, and other pharmaceutical products. In addition, sodium laurate can be used to prepare soap, soap, and other cosmetic raw materials.

Oral cleaning product

Sodium laurate can prepare oral cleaning products, such as toothpaste, mouthwash, etc. In these products, sodium laurate can be used as an additive such as an emulsifier, wetting agent, and antibacterial agent to help improve the cleaning effect and antibacterial ability of the product.

Textile and printing

Sodium laurate is also used in the textile and printing industry. It can be used as a softener, antistatic agent, emulsifier, and other additives to help improve the quality and processing performance of textiles. In addition, sodium laurate can also be used to prepare fine chemicals such as dyeing auxiliaries and printing and dyeing auxiliaries.

Petroleum industry

Sodium laurate can be used in the petroleum industry as an additive, emulsifier, wetting agent, and other applications in petroleum, chemical industry, textile, and other fields. It can be used to prepare other laurate compounds, surfactants, and other fine chemicals to help improve the efficiency of oil extraction and processing.

Pesticides and fertilizers

Sodium laurate can prepare additives in pesticides and fertilizers, such as wetting agents, dispersants, stabilizers, etc. It can improve the distribution and absorption effect of pesticides and fertilizers and help improve the yield and quality of crops.
