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.

Application

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
