Why 100% USP Grade Pure Castor Oil

100% USP Grade Pure Castor Oil delivers the stringent purity standards and precise chemical consistency demanded by regulatory-driven manufacturing sectors. Formulators choose this exact United States Pharmacopeia certified grade because it guarantees strict compliance for pharmaceutical, cosmetic, and personal care formulations. As a 100% concentration of C18H34O2 (CAS 8001-79-4), this pale yellow viscous liquid provides a reliable, translucent, and smooth base material without introducing unverified impurities. The exact chemical profile ensures predictable behavior during compounding, while its water insoluble nature and high flash point of 246 establish stability under thermal stress. Buyers responsible for passing strict regulatory audits depend on this USP verification to establish a documented baseline of purity, ensuring the oil meets exact pharmacopeial requirements before it ever enters a sensitive production run.

Best Applications for This Grade

  • Commonly applied in pharmaceutical manufacturing as an excipient and trusted delivery vehicle, where strict USP certification validates the baseline purity required for both topical ointments and internal formulations.
  • Commonly applied in the formulation of cosmetics and personal care items, functioning as an effective emollient that leverages the translucent smooth texture of the oil to provide thick, stable viscosity to lip balms, skin creams, and specialty soaps.
  • Commonly applied in the production of bio-based polyurethanes and advanced polymer resins, where the 100% concentration ensures strict moisture control and predictable hydroxyl functionality, preventing unwanted side reactions during polymerization.
  • Commonly applied in specialized industrial coatings and lubricants that demand an organic solvent soluble additive, utilizing the high flash point of 246 to maintain stability in high-temperature environments while remaining completely water insoluble.

When to Choose a Different Grade

  • If the manufacturing process requires a raw material that dissolves readily in aqueous systems, as this unmodified C18H34O2 formula is strictly water insoluble and only organic solvent soluble.
  • If the specific formulation requires a solid or semi-solid structural component at room temperature, requiring a chemically modified hydrogenated castor oil rather than a translucent smooth liquid.
  • If the end product necessitates an emulsifier or surfactant capable of mixing oil and water phases together, necessitating an ethoxylated castor oil rather than this 100% pure base oil.
