Uses2

  • For Castor oil (USEPA/OPP Pesticide Code: 031608) ACTIVE products with label matches. /SRP: Registered for use in the U.S. but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses./
  • CASTOR OIL HAS BEEN REPORTED USED IN FOLLOWING: NON-ALCOHOLIC BEVERAGES: 1.5-140 PPM, ICE CREAM, ICES, ETC: 3.0-540 PPM; CANDY: 3.0-410 PPM; BAKED GOODS: 210 PPM
  • MEDICATION **PEER REVIEWED**
  • MEDICATION (VET) **PEER REVIEWED**
  • As an industrial raw material for the prepn of chemical derivs used in coatings, urethane derivs, surfactants and dispersants, cosmetics, lubricants; chief raw material for the production of sebacic acid, a basic ingredient in the production of synthetic resins and fibers; as lubricant in metal drawing, machine lubrication and 2-cycle engine fuels, in hydraulic fluids, rubber preservative and mold lubricants; constituent of embalming fluids; in soap manuf; to impart emollient and lubricant properties to cosmetic prepns; as Turkey-red oil (sulfated castor oil) for dyeing and finishing textiles; as dehydrated castor oil in alkyds, resinous copolymers, varnishes, oil-based paints, enamels, caulks and putties; as blown oil (oxidized oil) for plasticizing oilcloth, artificial leather, coated fabrics, and lacquers, to plasticize rosin in the manuf of sticky fly-paper, for nitrocellulose and similar coating systems, hot melts, duplicating and stencil inks, adhesives and laminants; as release and anti-sticking agent in hard candy manuf.
  • Prodn of elastomers, fatty acids, electrical insulating compd
  • IN MFR OF FUNGICIDES /DEHYDRATED CASTOR OIL/
  • PLASTICIZER IN NITROCELLULOSE LACQUER; CHEM INT FOR HEPTALDEHYDE, UNDECYLENIC ACID & 2-OCTYL ALCOHOL **PEER REVIEWED**
  • Used as a chemical intermediate for the synthesis of: alkyd resins, non-drying; castor oil, blown; castor oil, dehydrated; castor oil, hydrogenated; castor oil, sulfated; castor oil ethoxylates; factice; glycerol monoricinoleate; methyl ricinoleate; polyurethane, low-resilience elastomers; ricinoleic acid
  • Air-blown castor oil is used as a plasticizer for varnishes and polymers. The oil is used in the production of transparent soap, textile processing aids, special lubricants, and toiletries.
  • Another cosmetic application of aluminum compounds is as lakes for lipstick manufacture...These lakes are mixed with castor oil, finely ground, and used as lipstick ingredients.
  • Castor oil is used as a defoamer in industrial processes.
