Hydrogenated Castor Oil (HCO) – Flakes is a solid, wax-like castor oil derivative produced by hydrogenating refined castor oil. This process converts unsaturated bonds into saturated ones, resulting in a chemically stable, high-melting, and insoluble material widely used in industrial formulations where structure, consistency, and thermal stability are required.
Globally, HCO flakes are valued as a functional structuring agent and intermediate rather than a consumer ingredient.
Product Overview
Hydrogenated Castor Oil is derived from castor oil extracted from Ricinus communis seeds. After hydrogenation, the oil transitions from a viscous liquid into a hard, brittle solid, commonly supplied in flake form for ease of handling and dosing.
Common industrial forms:
-
Flakes
-
Pastilles / pellets (depending on supplier capability)
At a high level, HCO is produced through controlled hydrogenation followed by purification and solidification. Compared with non-hydrogenated castor oil and other castor derivatives, Hydrogenated Castor Oil offers higher oxidative stability and structural rigidity, making it suitable for applications requiring heat resistance and non-reactivity.
Manufacturing Process (High Level)
The manufacturing of Hydrogenated Castor Oil – Flakes follows a standardized, non-proprietary process framework.
1. Raw Material Sourcing
Refined castor oil derived from castor seeds is used as the primary feedstock.
2. Hydrogenation Reaction
Unsaturated bonds in the oil are saturated through hydrogenation, improving thermal and oxidative stability.
3. Refining & Purification
Post-reaction processing removes residual impurities and ensures uniformity.
4. Solidification & Flaking
The hydrogenated oil is cooled, solidified, and converted into flakes for industrial handling.
5. Quality Control Stages
-
Incoming raw material checks
-
In-process monitoring
-
Final batch testing prior to packing
No proprietary temperatures, catalysts, or confidential processing details are disclosed.
