Refined Castor Oil (First Special Grade – F.S.G/British Standard Specifications-B.S.S)

   
 

It is a castor oil bleached to British Standard Specifications (BSS). It is a yellow viscous liquid free from suspended matter and insoluble in water.

 
 

APPLICATIONS:

 
 

FSG/BSS Castor oil finds application in a wide variety of uses and is the starting material for most other derivatives of castor oil.

 
   
     As an ingredient in pharmaceutical and cosmetic applications
     In combinations with styrene and diisocynates for a film forming Varnish or a substantially  insoluble infusible polymer
     As lubricant component of coatings for vitamin and mineral Tablets.
      As an ingredient for petroleum oil-field de-emulsification
     As capacitor impregnate
     As a sonar transducer fluid
     As a dielectric material for electrical condensers
     In manufacture of polyurethane casting resins
     In hydraulic fluids for automobiles, trucks and machinery
     As a starting material for most other derivatives of Castor Oil
