Frequently asked questions
What is organic castor oil commonly used for?
Organic castor oil is widely used in pharmaceuticals (e.g., laxatives), cosmetics (e.g., moisturizers, soaps), industrial lubricants, and biofuel production due to its non-toxic and renewable properties.
What is the chemical formula and molecular weight of organic castor oil?
Castor oil is a triglyceride blend, primarily composed of ricinoleic acid (C₁₈H₃₄O₃), but it does not have a single molecular formula or weight due to its complex natural composition.
How should organic castor oil be stored?
Store organic castor oil in a cool, dry place at ambient temperature, away from direct sunlight and contaminants, in tightly sealed containers to prevent oxidation.
