What is Sodium Stearate?
Sodium stearate is likewise referred to as sodium octadecanoate. It is a white oily powder with an oily feel and a fatty smell. It is absorptive in air.
Slightly soluble in cold water, quickly soluble in hot water or hot alcohol, very thick hot soap liquid will not crystallize after cooling. The liquid solution is alkaline due to hydrolysis, while the alcoholic solution is neutral.
The product has excellent emulsification, penetration and detergency. For that reason, it is usually used in the manufacture of tooth paste, and also is additionally utilized as a waterproofing representative and a plastic stabilizer.

Physicochemical Properties of Sodium Stearate
The hydrocarbyl moiety in the sodium stearate molecule is a hydrophobic group, and the carboxyl moiety is a hydrophilic group.
In soapy water, sodium stearate exists as micelles. The micelles are spherical and consist of many molecules. The hydrophobic groups are inwards, which are combined with each other by van der Waals forces, and the hydrophilic groups are outwards, which are distributed on the surface of the micelles.
The micelles are dispersed in water, and when encountering water-insoluble oil stains, the oil can be dispersed into fine oil droplets. The hydrophobic group of sodium stearate dissolves into the oil, while the hydrophilic group remains on the surface of the oil bead, so that the oil bead can be suspended in water and has a decontamination effect.
In hard water, stearate ions integrate with calcium as well as magnesium ions to create water-insoluble calcium and also magnesium salts, lowering the detergency.
Application
Main uses of sodium stearate: thickener; emulsifier; dispersant; adhesive; corrosion inhibitor, etc.
1. Detergent: It is used to make soap detergent and control the foam in the rinsing process.
2. Emulsifier or dispersant: Sodium stearate is used as an emulsifier in cosmetics, for polymer emulsification and also antioxidant.
3. Deterioration inhibitor: It has protective buildings in the collection product packaging film.
4. It is made use of in the manufacture of tooth paste as well as additionally as a waterproofing agent.
5. Adhesive: made use of as natural adhesive to paste paper.
6. It can also be used as metal warm therapy as well as plastic stabilizer.
7. Polyvinyl chloride warmth stabilizer, and also resources for cosmetic flour, emollient ointment and also pharmaceutical tablet computers.
