Sodium stearate has a wide range of uses.
Applications of Sodium Stearate:
emulsifier and dispersant in latex paints;
ink thickener;
stabilizer, viscosity enhancer, and dispersant for liquid makeup;
FDA-approved flavor additive;
viscosity modifier in gelled fragrances;
lubricant in polycarbonates and nylons, and
lubricant and de-dusting agent in rubber production.
Sodium stearate is a sodium salt commonly used as a surfactant and emulsifying agent in the food industry.
The drug interactions with sodium stearate are not well known, but it has been shown to affect fetal bovine serum (FBS) cell viability at concentrations above 10%.
Sodium stearate typically shows a 5–6% thermal expansion per degree Celsius.
It is also used with CO2 flow to produce anhydrous sodium carbonate and sodium bicarbonate.
Sodium stearate can be found in foods such as margarine, shortening, and baking powder.
It also has metabolic effects, such as promoting insulin production and reducing blood sugar levels.
Application in Cosmetics:
Sodium Stearate is a viscosity controller and a texture enhancer widely used in the cosmetic industry.
Sodium Stearate also works as an acceptable cleansing agent in skin care, mixing well with water to wash away dirt residue.
Sodium Stearate can be produced synthetically or derived from animal sources - typically appearing as a smooth white powder in its raw form.
Further, Sodium Stearate has excellent waterproofing qualities and is often added to solid products like stick sunscreens, chapsticks, and bar soaps.
The drawback to sodium stearate is that it can dry extremely on the skin if not formulated properly.
Sodium Stearate is a valuable ingredient in the cosmetic and personal care industry.
It primarily works as a texture enhancer to help formulate quality products.
Decorative cosmetics: Sodium Stearate controls the viscosity and acts as a binder in cosmetic products like foundations, lipsticks, and eyeshadows.
It stabilizes and gives structure to these products, ensuring they maintain their desired consistency and adhere effectively to the skin for long-lasting wear.
Skincare: In skincare, sodium stearate functions as a surfactant and emulsifier.
Sodium Stearate enables the creation of stable emulsions in creams, lotions, and moisturizers, effectively blending water- and oil-based ingredients.
Additionally, its cleansing properties make it a key component in facial cleansers and soaps, helping to remove dirt, oil, and impurities from the skin.
Sodium Stearate is a vegetable-based aqueous thickener and gelling agent, emulsifying agent(o/w), and cleansing agent.
Consists primarily of the sodium salts of saturated C16 & C18 fatty acids.
Multi-functional ingredient with thickening, gelling, and emulsifying properties.
Widely used as a thickener in stick products (e.g., deodorants) and co-emulsifier in creams and lotions.
Sodium stearate is a stabilizer and thickener that helps harden soaps and naked deodorants, allowing a wide variety of shapes and sizes and removing the need for unnecessary packaging and synthetic preservatives.
Sodium Stearate also has opacifying properties that give the foam a creamy white appearance.
Use
Sodium stearate has the characteristics of soaps: hydrophilic and hydrophobic parts, carboxylate, and long hydrocarbon chains.
These two chemically different components induce the formation of micelles, which present the hydrophilic heads outwards and their hydrophobic (hydrocarbon) tails inwards, providing a lipophilic environment for hydrophobic compounds.
The tail part dissolves the grease or dirt and forms the micelle.
It is also used in the pharmaceutical industry as a surfactant to aid the solubility of hydrophobic compounds in producing various mouth foams.
Production of Sodium Stearate:
Sodium stearate is a significant soap component used to saponify oils and fats.
The percentage of sodium stearate depends on the fats in the ingredients.
Tallow is exceptionally high in stearic acid content (as in triglyceride), whereas most fats only contain a small percentage.
The idealized equation for the formation of sodium stearate from stearin (the triglyceride of stearic acid) follows:
(C18H35O2)3C3H5 + 3 NaOH → C3H5(OH)3 + 3 C18H35O2Na
Purified sodium stearate can be made by neutralizing stearic acid with sodium hydroxide.
C17H35COOH+NaOH→C17H35COONa+H2O
