What does Pharmaceutical Grade Castor Oil (USP/BP) mean?

It means the castor oil complies with both United States Pharmacopeia (USP) and British Pharmacopoeia (BP) quality standards for pharmaceutical use, including strict limits on purity, contaminants and performance tests.

Is CanCastor Pharmaceutical Grade Castor Oil suitable for oral use?

Yes, pharma‑grade castor oil that meets USP/BP standards is widely used in oral laxatives and capsule formulations, provided it is used according to applicable regulations and medical guidance.

Can this grade be used in topical and ophthalmic products?

Pharmaceutical grade castor oil is commonly used as an emollient and solubilizer in ointments, creams, ophthalmic preparations and medicated lotions because of its high purity and good skin and eye tolerance.

What is the difference between USP and BP grades in this product?

Both refer to pharmacopeial monographs with very similar quality requirements; a USP/BP grade is refined to meet the critical test limits of each, so buyers can use the same oil for markets governed by either pharmacopeia.

How is Pharmaceutical Grade Castor Oil typically packaged?

Pharma‑grade castor oil is usually supplied in well‑sealed, inert‑lined steel or HDPE drums (around 180–200 kg) and, for smaller volumes, in certified pharma containers such as cans or bottles, sometimes under nitrogen for extra stability.

How should this product be stored to maintain quality?

Store in tightly closed containers in a cool, dry place away from direct sunlight and strong oxidizers; under good storage conditions, pharmaceutical grade castor oil remains stable for extended periods without significant oxidation.

Is Pharmaceutical Grade Castor Oil bio‑based and sustainable?

Yes, castor oil is derived from castor seeds, a renewable, non‑edible oil crop, and is considered a bio‑based raw material widely used in sustainable pharmaceutical and personal‑care formulations.
