Hydrogenated castor oil is produced through a hydrogenation process where castor oil is treated with hydrogen in the presence of a nickel catalyst. This process saturates the ricinoleic acid in castor oil and forms a wax-like product with a high melting point of 86°C. Hydrogenated castor oil has various applications and is used to manufacture greases, soaps, cosmetics, and specialty chemicals for industries like metalworking, plastics, and textiles. It also acts as a rheological agent in products like paints, coatings, inks, and adhesives.

DATA BASES

5. Hydrogenated castor oil - Applications
• Hydrogenated castor oil used in the manufacture of multipurpose
Lithium/Calcium grease and high performance aviation grease.
• Hydrogenated castor oil used for the manufacture of soaps &
cosmetics
– It is used in the manufacture of specialty chemicals for applications such as
metal working, plasticizers and textile auxiliaries in the form of derivatives
such as esters, ethoxylates, sulfates .
– It is also used as a Rheological agent that provides thixotropy in paints,
coatings, inks, adhesives, sealants and numerous industrial composition.

6. Hydrogenated castor oil
Production Process
• It is produced by adding hydrogen in the presence of a nickel catalyst.
• In the hydrogenation process, the ricinoleic acid becomes fully
saturated and forms a viscous wax-like product with a high melting
point of 86°C, which makes HCO valuable in resin and polymer
mixtures.

8. PRODUCTSTOMANUFACTURE

10. The raw material, bleached castor oil (BBS grade) is processed
under vacuum condition at a temperature of around 160 degree
Celsius in presence of nickel catalyst
As soon as the raw material reaches its required temperature, the
vacuum is stopped and hydrogen is fed, while the stirrer is still
operating
The hydrogen feed is closed as the required degree of
hydrogenation is achieved and after this, hydrogenated product is
started cooling
As the product temperate reaches around 100°C, the final product
gets filtered, cooled and then conveyed to flaking unit for flaking
and bagged
Process Description For Hydrogenated Castor Oil [HCO]

11. Project Description
• The Project envisages setting up of a manufacturing unit for
producing the various derivatives of Castor.
• The project will involve the purification of Castor oil and
subjecting it to various treatments such as dehydration,
hydrogenation, saponification, acidification etc. to extract various
derivatives such as dehydrated castor oil, hydrogenated castor oil,
12-hydroxy stearic acid etc.
• There are about 200 castor oil derivatives, however the project will
involve the production of only selected few that are commercially
important and find applications in industrial products.
