Castor Oil
Castor oil is unusual among vegetable oils because its dominant fatty acid, ricinoleic acid, carries a hydroxyl group on the chain. That single structural feature gives the oil its high viscosity, its solubility behaviour in polar solvents and, more commercially important, a reactive site that oleochemical producers use to build polyols, sulphated oils, sebacic acid and a long list of derivatives. Buyers purchase it either as a functional oil in its own right or as a chemical feedstock. Allzone quotes this material per enquiry: grade, packing, origin, documentation and Incoterm are decided in your quotation, not fixed by this page.

Technical & procurement detail
What castor oil does in a formulation+
It provides high viscosity and lubricity in oil formulations, acts as a plasticiser and wetting oil in coatings and inks, serves as an emollient and pigment-wetting agent in personal care, and supplies the hydroxyl functionality that polyurethane and oleochemical chemistry is built on. Suitability for a specific claim or reaction is confirmed against producer documentation for the grade offered.
What decides the grade you actually need+
Whether you are using it as a functional oil or as a feedstock decides the grade: refining level, colour, acid value convention and moisture matter differently in a cosmetic product, a lubricant and a polyol reaction. State the application, the property window your specification calls for, the documentation your sector requires, the packaging your intake can receive and the annual volume.
Castor oil and its derivative family+
Hydrogenated castor oil, castor wax, dehydrated castor oil, sulphated (Turkey Red) oil and castor-based polyols are chemically modified derivatives with their own commercial identities and are not grades of this page's material; they are reviewed per enquiry. Ricinus oil and castor seed oil are alternative names for this same product. Refining levels, colour grades and packaging formats are handled inside this record and never published as separate pages.
Specification conventions and how to state yours+
Suppliers report active content, solution strength, particle presentation and impurity limits in different conventions, and the numbers are not interchangeable between them. State the convention your specification uses along with the property window you actually need, and comparison is made like for like against producer data for the grade offered.
What this page does not state+
This page asserts no purity, assay, active content, concentration, moisture, pH, density, dosage rate, performance figure, approval, registration, certification, origin, packing, minimum quantity, availability, lead time or price. Every commercially meaningful value is taken from producer documentation for the exact grade offered and confirmed in writing before order.
Sourcing and origin+
Allzone sources this material through producer channels and quotes it per enquiry. Origin, production route and shipping point are selected against your technical requirement, quantity, documentation need and destination, and are stated in the offer rather than fixed by this page. Freight, discharge point and packaging format move landed cost, so quotations are compared delivered to your plant.
Documentation supplied with an offer+
Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Handling, storage, incompatibility and personal-protection requirements are treated as SDS questions for the specific grade rather than figures published here. Where a declaration matters to your application — food contact, cosmetic, potable water, feed or regulatory — it is confirmed for that grade and intended use rather than assumed from this page.
How Allzone quotes this+
Send the process it goes into, the function you need it to perform, the property window your specification calls for in your own convention, the annual and per-shipment quantity, the packaging format your intake can receive, the documentation required per shipment and the delivery province or port. Several materials can be listed in one enquiry and reviewed together rather than split into separate requests.
Frequently asked questions
Does Allzone publish a price for castor oil?+
No. Price, minimum quantity, origin, packing and lead time depend on the grade, the volume and the destination, and are confirmed at quotation. Nothing on this page is an offer.
Which grades or presentations can be quoted?+
Industrial and technical grades, Refined and pharmaceutical presentations, Feedstock presentations for derivative chemistry, Drum, IBC and bulk formats are handled inside this single product record. Grades, concentrations and applications of one material are not published as separate pages; the grade offered and its published data are confirmed in the quotation.
What documentation is available for castor oil?+
Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Handling, storage, incompatibility and personal-protection requirements are treated as SDS questions for the specific grade rather than figures published here. Where a declaration matters to your application — food contact, cosmetic, potable water, feed or regulatory — it is confirmed for that grade and intended use rather than assumed from this page.
Can castor oil be supplied into Ontario and the GTA?+
Delivery and logistics into Ontario, Quebec and the rest of Canada are reviewed per enquiry alongside the rest of the offer. We publish no stock, inventory or delivery-window guarantee on this page.
