Description

Chemical Name:Sodium stearate
Molecular Formula: C18H35NaO2
Molecular Weight: 306.45907
Structural Formula:

Sodium stearate has emulsifying properties, reducing the interfacial tension between oil and water, enabling immiscible liquids to form a stable emulsion.
Sodium stearate in powder or granular form has a low friction coefficient, reducing friction between solid surfaces.
In liquid systems, sodium stearate increases system viscosity, enhancing product stability.
As a surfactant, sodium stearate can emulsify and disperse oil stains in water, achieving a cleaning effect.
Under certain conditions, sodium stearate can form a uniform film or react with other substances to form a solid structure, serving a shaping or curing function.

Sodium stearate is a primary component of soap and detergents and is also used in toothpaste manufacturing.
Sodium octadecanoate serves as an emulsifier and thickener in creams and lotions.
Sodium stearate is used as a thermal stabiliser and lubricant in plastics such as polyvinyl chloride (PVC), and as a release agent in rubber products.
In metal processing, Sodium octadecanoate is used as a lubricant and rust inhibitor.
Sodium stearate can be used in concrete or mortar in construction and building materials to improve their plasticity and lubricity; it is also used in the production of waterproofing membranes to enhance the material’s water resistance.
In pharmaceutical formulations, sodium stearate serves as a base component for medicinal ointments and suppositories.
In certain food processing applications, it functions as an emulsifier or release agent.
As a thickener and dispersant, stearic acid sodium salt improves the flow properties and stability of coatings, preventing pigment settling.
It is used in fabric softening treatments to make fibre surfaces smoother and enhance tactile feel.
