Sodium Oleate Overview

One of the most important components of soap made of olive oil is sodium oleate. This can also make up a significant part of tallow soap. It is a mixture of hydrophilic and hydrophobic elements. It has high emulsifying powers, penetrating strength, and detergency. Also, it is well-soluble in hotwater. It serves as an anionic solvent and fabric waterproofing agents.

The nature and uses of sodium Oleate

1. Oxidation The color can also be gradually oxidized, and then colored in the open air. This will darken it and cause rancidity. Oleic acid, which is also known as oleic acid, is destroyed by oxidation. Additionally, double bonds can be broken to make dangerous substances such as furfural. Corruption is encouraged by the mixing of high unsaturated acids.

2, Solubility

This solution dissolves in 10x more water. The foaming results in a viscous, clear liquid. The alkaline aqueous solution makes the liquid turbid because of partial reaction to insoluble acidic detergent and sodium hydroxide. It is insoluble when ethanol is used and neutral. About 20 times more ethanol will dissolve. Do not mix with ether, petroleum alcohol or other organic solvents. 3. Chemische Reaktion

When it is mixed with another metal ion, it forms a metal salt precipitate.

4, additional properties

In general, salt has no volatile nature. It can be dissociated completely into ions by adding water. Add inorganic acid to the soap liquid and it can become hydroxy acid. If the hot soap liquid cools, it will not crystallize. Instead, precipitates are formed of insoluble calcium/magnesium soap with calcium or magnesium salts. Property and appearance: A white powder with a melting point of between 232 and 235°C. ); boiling points: 359.999oC @ 760mmHg; flashpoint = 270.099oC. This product is not compatible with strong-oxidizing agents. Storage Conditions: At -20°C

Preparation sodium oleate

It can be obtained by neutralizing either sodium hydroxide, or sodium carbonate within an oleic acid-ethanol solution.

10g of oleic Acid can be mixed in 100 mL (95% ethanol) and then titrated using sodium hydroxide, which has a concentration at 0.5mol/L. After reaching the equivalence points, the precipitated sodium oil soap was filtered. It is possible to distill ethanol from water to remove the precipitate.

Use of sodium Oleate

1. It is also the main ingredient in soap made from olive oils, etc.

2, which can be used in food films like fruit, vegetable skin film, can use ethylene oxide and high boron alcohol.

3. The waterproofing and processing of mineral materials in fabrics 4 may be used as an anti-corrosion agent for aluminum alloys, copper and iron. 5. This is an anionic surfactant that can be used to waterproof fabric.

Safety in sodium oleate

Acute toxicities: LD50, half-lethal dose in mice, 152 mg/kg for rabbits; LD50, 150 mg/kg for humans. Avoid taking it internally. Use it on the skin or mucous membranes. The anionic surfactant sodium oleate, is also known as sodium oleate. Food Safety Law stipulates that this ingredient cannot appear in food safety standard food additive standards GB2760 –2011. Sodium oleate, therefore, is not a permitted food additive. It is safe to use in drinking water. But, sodium oleate cannot be dispersed into the environment without approval from the government.
