Pharmaceutical Grade Castor Oil Ricinoleic Acid Content Surfactant Lubricant

Medicinal grade castor oil Ricinus acid content Surfactant lubricant Castor oil Bima YouCASTOR OIL Castor oil is a fatty oil obtained by extracting and refining the mature seeds of Ricinus communis L.
, a plant of Euphorbiaceae
.

Castor oil is a clear, viscous liquid that is almost colorless or slightly yellow; the gas is slightly; the taste is light and then slightly acrid
.

　Castor oil is easily soluble in ethanol and can be freely mixed with absolute ethanol and glacial acetic acid
.

The relative density should be 0.
956~0.
969 at 25°C (general rule 0601)
.

The refractive index should be 1.
478~1.
480 (general rule 0622)
.

[Identification] Take the supernatant after dehydration of anhydrous sodium sulfate under the item [Determination of Content] as the test solution
.

Take methyl ricinoleate reference substance, add n-hexane to make a solution containing 2mg per 1ml, as the reference substance solution
.

According to the thin-layer chromatography (general rule 0502) test, draw 5 μl of each of the two solutions, respectively point them on the same silica gel G thin-layer plate, and use petroleum ether (60~90℃)-
.
.
.

- Formic acid (11:4.
5:0.
5) as the developing agent, unfold, take out, air dry, and smoke in iodine vapor until the spots become clear
.

In the chromatogram of the test substance, the same yellow spot was displayed on the corresponding position of the chromatogram of the reference substance
.

　　[Check] The acid value should not be greater than 2.
0 (general rule 0713)
.

Castor oil is used in the manufacture of plasticizers, dibasic acids, polyurethane coatings, rubber, adhesives, fatty acids, surfactants, insulating oils, hydraulic oils, lubricating oils, polyamide-11 fibers, and more
.

Castor oil is dehydrated to obtain a dry oil with conjugated double bonds
.

A variety of products can be obtained by hydrogenation under different conditions
.

Castor oil is used as the main base for lip balms, but also in creams, lotions and hair care products
.

Castor oil is used in the manufacture of Turkish red oil, as a textile industry auxiliaries and oils; in the production of transparent soaps, liquid potassium soaps, cosmetics,
etc.

Castor oil and castor oil derivatives are widely used in pharmaceuticals, cosmetics, lubricating oils, lubricants, metalworking oils, fiber oils, coatings, plastics, adhesives, plasticizers, and the like
.

Castor oil has good compatibility with nitrocellulose, ethyl cellulose, cellulose acetate butyrate, polyamide, butylated melamine (or urea) formaldehyde resin, rosin, shellac, etc.
, and can be used as a plasticizer
.

In addition, it also has good compatibility with polyvinyl butyral, polyvinyl chloride-polyvinyl acetate-vinyl alcohol copolymer, and chlorinated rubber
.

Castor oil has good stability, color retention, flexibility, pigment dispersion, wetting, lubricity, low temperature properties, electrical properties and biological properties, so it can be used in varnish coatings, artificial leather, inks, Sealants, lubricants, stationery, cosmetics, electrical insulating materials, medicine,
etc.
