Properties of Sodium Laurate: 
Sodium laurate (CAS 629-25-4) is a fine white powder; soluble in hot water and hot ethyl alcohol; lightly soluble in cold ethyl alcohol, ether and another organic solvent.


How is Sodium Laurate Produced?
1. The coconut oil or palm oil is added to the saponification kettle and heated directly with steam to melt.
2. Add NaOH aqueous solution three times, and saponify at reflux temperature for about 6h to get the crude soap.
3. Add saltwater into the crude soap solution, stand and separate impurities and by-product glycerin to get soap glue.
4. The sodium laurate product can be obtained by adjusting the pH value to about 8.5 with lye.
 
Applications of Sodium Laurate:
Sodium laurate can be used as soap, cleaning agent, and insecticide.
Sodium laurate is also used in organic synthesis
Sodium laurate is an important raw material for making soaps and shampoos for textiles and an indispensable component in soaps.
Sodium laurate can be used as a cosmetic excellent surfactant, emulsifier, lubricant, detergent.

Industrial sector
In the industrial field, the main application of sodium laurate is as a surfactant and emulsifier. In the petroleum industry, sodium laurate can be used to reduce the surface tension of water, thereby improving oil recovery. In addition, sodium laurate can produce detergents, wetting agents, penetrating agents, etc.

Food sector
In the food industry, sodium laurate is widely added as a preservative and antioxidant to various foods. It can effectively inhibit the growth and reproduction of microorganisms and extend the shelf life of food. In addition, sodium laurate can be used as a spice to prepare various food essences.

Daily chemical industry
In daily chemicals, sodium laurate is mainly used as an additive in detergents and cosmetics. It can improve the product's foaming performance, washing effect, and skin touch. However, adding sodium laurate may also cause skin dryness and allergies, so appropriate control should be exercised.

Medical field
In medicine, sodium laurate has pharmacological effects such as anti-inflammatory, anti-tumor, and antibacterial. It is often used as a pharmaceutical intermediate or active ingredient, such as in preparing antibiotics and other drugs. However, the toxicity of sodium laurate limits its application in the pharmaceutical field.

FAQs of Sodium Laurate CAS 629-25-4

Q: What is sodium laurate used for?

A: Sodium laurate, identified by the CAS number 629-25-4, serves a variety of purposes across different industries due to its versatile properties. In cosmetics and personal care products, it functions as an emulsifying agent, surfactant, and foaming agent, enhancing the cleansing and textural qualities of soaps, shampoos, and body washes. Within the food industry, sodium laurate can be utilized as a flavor enhancer or stabilizer in certain applications. Additionally, this compound finds use in the production of detergents and cleaning agents, where it contributes to effective stain removal and soil suspension. It also has applications in pharmaceuticals, aiding in the formulation of tablets and other dosage forms by improving the flowability and compressibility of powders.
 

Q: Is sodium laurate safe for humans?

A: Sodium laurate is generally recognized as safe (GRAS) for use in both cosmetic and food applications when used within recommended concentration limits and following good manufacturing practices. Studies have indicated that this compound exhibits low toxicity and does not typically cause significant irritation or sensitization when applied topically or ingested within typical usage levels. However, during handling, precautions should be taken to avoid inhalation of dust particles and contact with eyes. The use of appropriate personal protective equipment (PPE), including gloves, safety glasses, and respiratory protection, can ensure safe handling. For specific applications, especially those involving ingestion or prolonged skin contact, consulting relevant safety data sheets and regulatory guidelines is advisable.
 

Q: What is the chemical composition of sodium laurate?

A: Sodium laurate is a metal soap derived from the reaction between sodium hydroxide (NaOH) and lauric acid, a medium-chain fatty acid typically found in coconut oil. Chemically, it consists of sodium ions (Na⁺) and laurate ions, which are long-chain fatty acids composed of twelve carbon atoms. This combination results in a material that possesses amphiphilic properties, meaning it has both hydrophilic (water-attracting) and hydrophobic (water-repelling) characteristics. These properties make sodium laurate effective as an emulsifier and surfactant, capable of stabilizing mixtures of oil and water and lowering the surface tension between substances. The exact ratio of components may vary depending on the manufacturing process and intended application, allowing for customization of physical and chemical properties to meet specific requirements.
 

Q: How does sodium laurate perform in skincare products?

A: Sodium laurate performs effectively in skincare products, offering multiple benefits. As an emulsifying agent, it helps create stable formulations by keeping oil and water phases from separating, ensuring product consistency over time. Its surfactant properties contribute to the cleansing action of products like soaps and cleansers, helping to remove dirt and oils from the skin without causing excessive dryness. Sodium laurate can also enhance the foaming quality of products, providing a rich lather that improves the sensory experience of using the product. Importantly, sodium laurate is non-toxic, non-irritating, and non-sensitizing, aligning well with the safety standards expected in skincare formulations. Additionally, its ability to improve the spreadability and wash-off characteristics of products makes it a valuable ingredient in formulations designed for ease of use and effectiveness.
