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
