  • Does super refined castor oil have superior oxidative stability?
  • To demonstrate superior oxidative stability, five lots of Super Refined Castor Oil were compared against five lots of standard compendial grade castor oil over a period of 8 weeks at 50 oC 1. Both peroxide and iodine value were analysed according to the USP test method.
  • Does super refined castor oil have a high peroxide and iodine value?
  • Both peroxide and iodine value were analysed according to the USP test method. It was noted that the Super Refined Castor Oil maintained a low peroxide (<2ppm) for the duration of the study while the standard grade exhibited a significantly higher initial peroxide value with an 83% increase after 8 weeks (Figure 5).
  • What is castor oil?
  • As the pioneer of castor oil manufacturer in Japan, we have been engaged to improving the quality and stable supply of castor oil, which is used for a wide variety of application since the establishment. ● Castor Oil is extracted from castor seeds. This oil is an ester consisting of glycerin and fatty acid.
  • Why is castor oil a nondrying oil?
  • Because ricinoleic acid occupies fatty acids at 90%, castor oil displays unique characteristics which is different from other plant oils. This light yellow viscous nondrying oil, castor oil is compatible in most organic solvents (except for aliphatic hydrocarbon solvent) and even in ethyl alcohol.
