It is almost colorless or slightly yellow, clear and viscous liquid; has a slight odor; has a light taste and then is slightly pungent, and is easily soluble in ethanol. , can be mixed with absolute ethanol, chloroform, ether or glacial acetic acid at will, and should be widely used in coatings.
There are many derivatives of castor oil. The following suppliers of castor oil will help you understand them. Sulfonated castor oil:
Sulfonated castor oil is also called ancient oil or Turkish red oil. It is produced by neutralizing castor oil and sulfuric acid.
Sulfonated castor oil anionic surfactant. Yellow to brown thick oily transparent liquid. Castor oil low sulfonated oil. The composition is very complex. Fatty acid content 44.2%, organically bound sulfur 2.16%, sulfonation degree 22% , easily soluble in water, has stronger acid resistance, hard water resistance and emulsification than ordinary soap; strong wetting and penetrating power.
Sulfonated castor oil has the functions of dispersing, lubricating and emulsifying, Mainly used as oil agent, dyeing auxiliary, fiber treatment agent, smoothing agent for fiber fabrics, and also used as pesticide emulsifier and emulsifier for metal processing. Sulfonated castor oil used in papermaking coatings is required to give the coating good fluidity, Coatability, improve the water retention of the coating, control the migration and penetration of the coating liquid to the surface of the base paper, so as to enhance the bonding strength between the coating and the base paper.
