Product Overview
100% USP Grade Pure Castor Oil (CAS 8001-79-4) is undiluted castor oil pressed from the seeds of Ricinus communis, offered with the USP Grade designation that pharma, cosmetic, and personal-care formulators commonly specify when sourcing raw materials. It is the same viscous, ricinoleic-acid-rich oil that industrial buyers run as a lubricant base and plasticizer feedstock — listed here in pack sizes from 1 quart bottles to 330 gallon totes, available to order from our Taylor, Texas warehouse. If your purchasing spec calls out castor oil by CAS number and a USP Grade descriptor, this is the listing to quote against.
Why This Concentration
At 100%, you are buying the neat oil — no carrier, no dilution, no added surfactant package. That matters in two ways. First, formulators keep full control: you meter the oil into your own emulsion, lubricant blend, or cosmetic base at whatever loading your process requires. Second, procurement stays clean: one CAS number on the PO, one material on the SDS, no co-ingredient to qualify.
The grade descriptor is the real decision point in this family. Buyers in cosmetic and pharmaceutical formulation workflows typically request the USP Grade designation and then verify the lot against its certificate of analysis. If your workflow instead calls for a laboratory-style grade descriptor, see our 100% Pure Castor Oil ACS Grade. For general industrial uses — lubricant blending, mold release, plasticizer work — where no grade designation is specified, the standard 100% Pure Castor Oil is usually the economical pick. A grade label on its own is a procurement designation, not a certification; confirm the lot documentation covers whatever your quality system requires.
Chemical Profile
This product is identified by CAS number 8001-79-4, the registry number for castor oil (also listed under the synonyms Ricinus Communis Oil and Castor Bean Oil). As a natural triglyceride rather than a single defined molecule, it carries no single molecular formula or molecular weight; buyers specify it by CAS number, grade descriptor, and lot documentation. Its working character is what castor oil is known for across industrial use: a notably viscous vegetable-derived oil whose fatty-acid profile is dominated by ricinoleic acid — the structural feature that gives it lubricity and compatibility in ester and polymer chemistry. Lot-specific measured values are reported on the certificate of analysis rather than baked into this page.
Industrial Applications
-
Lubricant base stocks: castor oil's high viscosity and polar ricinoleic backbone make it a long-standing base for industrial lubricant applications where mineral oils fall short on film strength or material compatibility.
-
Plasticizer feedstock: in flexible plastics manufacturing, castor oil and its derivatives soften polymer matrices, improving flexibility in the finished part.
-
Cosmetic emollient: personal-care formulators use castor oil as an emollient in skin- and hair-care bases; the USP Grade descriptor is the designation those buyers most often request on the PO.
-
Surfactant and emulsion work: in chemical processing, castor oil serves as a raw material for surfactants and as a component in emulsion formulations.
-
Pharmaceutical formulation: castor oil appears as a raw material in pharma manufacturing workflows; formulators evaluate each lot against their own quality requirements using the supplied documentation.
Handling & Storage
This product is not classified as hazardous under GHS based on available data (per the product's GHS classification), and no signal word applies. That makes it one of the simpler materials our warehouse team handles — but standard industrial practice still applies. Wear gloves and goggles when transferring, and keep ventilation adequate around open containers. Store the oil cool, dry, and out of direct sunlight in HDPE or glass containers to prevent contamination, and avoid sustained high temperatures, which degrade the oil over time. Bung drums and totes tightly between draws; like any vegetable oil, castor oil picks up contamination and oxidizes faster in a half-open container.
Hazmat & Shipping
Castor oil carries no UN number, hazard class, packing group, or proper shipping name — it is not regulated as a hazardous material for ground transport (per 49 CFR 172.101). For receiving teams, that means this material moves as ordinary freight under DOT rules; it does not trigger hazmat placarding requirements. Note that transport classification governs only the regulatory status of the material itself — individual carrier services and fees are set by the carrier. Our team packs quarts and gallons case-style, palletizes 5 and 15 gallon containers, and ships 55 gallon drums through 330 gallon totes as standard bulk freight from Taylor, TX.
Documentation
A Safety Data Sheet ships with every order and is available in English, Spanish, French, and Japanese — useful when your EHS binder or an overseas affiliate needs a non-English copy. A lot-specific certificate of analysis is available with your shipment, which is the document cosmetic and pharma buyers should file against their incoming-QC record. A technical data sheet is also available for engineering review before you commit to a drum or tote quantity.
