Chemical Structure
Basic Info
Sodium steam is an organic compound, a white oily powder with a smooth and fatty odor. Its aqueous solution is alkaline due to hydrolysis, while its alcohol solution is neutral. Prepared by the interaction of octadecanoic acid and sodium hydroxide.
The following is an introduction to the properties, uses, production methods, and safety information of Sodium steam:
Properties of Sodium Steam:
Sodium steam is a solid at room temperature and soluble in water and alcohol solvents.
Sodium steam has good surface activity properties and can be used as an emulsifier, stabilizer, and additive.
Sodium stearate has good lubricating properties and is used to prepare various types of lubricants.
It also has anti-static and anti-corrosion properties.
Sodium stearate is the sodium salt of stearic acid, also known as sodium octadecate, and is a commonly used anionic surfactant and the main component of soap.
The alkyl group in sodium stearate molecules is hydrophobic, while the carboxyl group is hydrophilic. In soapy water, sodium stearate exists in the form of micelles, which are spherical and composed of many molecules. The hydrophobic groups are inward and bound to each other by van der Waals forces, while the hydrophilic groups are outward and distributed on the surface of the micelles.
Micelles disperse in water and when encountering insoluble oil stains, they can disperse the oil into small oil droplets. The hydrophobic groups of sodium stearate dissolve into the oil, while the hydrophilic groups remain on the surface of the oil droplets, allowing them to suspend in water and have a cleaning effect.
In hard water, stearic acid ions combine with calcium and magnesium ions to form insoluble calcium and magnesium salts, reducing the ability to remove dirt.

Product Packaging
Sodium stearate (molecular formula: C ₁₈ H ∝₅ NaO ₂) has various uses and is widely used in industries, cosmetics, pharmaceuticals, and food. The following are its main uses:
1. Manufacturing of detergents and soap
Sodium stearate is the main component of soap and belongs to anionic surfactants with excellent cleaning and emulsifying properties.
During the washing process, the hydrophobic groups in sodium stearate molecules bind with oil stains, while the hydrophilic groups disperse the oil stains in water, thereby playing a cleaning role
2. Cosmetics and personal care products
Sodium stearate is commonly used as an emulsifier and thickener for:
*Transparent soap
*Shaving cream and shaving gel
*Skincare products (such as moisturizers)
*Deodorizer
Its excellent stability and safety make it an ideal additive in the cosmetics industry
3. Plastic and rubber industry
As a lubricant and stabilizer, sodium stearate improves the processability of polyvinyl chloride (PVC).
In the rubber industry, it can be used as an additive to enhance the transparency and stability of rubber products
4. Waterproof agent
Sodium stearate can be used as a waterproofing agent and is widely used in paper, textiles, and building materials, endowing them with good waterproof performance.
5. Pharmaceutical field
In tablet production, sodium stearate is used as an excipient and lubricant, which helps to shape the tablets and reduce friction during production.
6. Food industry
Sodium stearate is used as a base substance in gum based candies to meet the food industry’s demand for thickening and bonding properties
7. Other uses
Paint industry: Sodium stearate can be used as a transparent leveling agent to improve the appearance and performance of paints.
Metal processing: used as a heat treatment agent to improve the lubricity and corrosion resistance of metal surfaces.
Sodium stearate is a versatile compound that plays an important role in daily life and industrial production due to its emulsifying, thickening, stain removing, and stabilizing properties. It is particularly widely used in soap manufacturing, cosmetics, and plastic industries.
