Methyl 12-Hydroxy Stearate (Methyl 12HSA) Product Overview
Methyl 12-Hydroxy Stearate (Methyl 12HSA) is a castor oil–derived fatty acid ester produced by esterification of 12-Hydroxy Stearic Acid with methanol. It is valued for its controlled melting behavior, lubricity, and compatibility with a wide range of organic systems.
This product is commonly used as a functional intermediate where smooth processing, predictable rheology, and consistent ester performance are required.
Manufacturing / Processing (High-Level)
Methyl 12HSA is manufactured through controlled esterification, followed by purification and solidification. The process is designed to:
- Achieve consistent ester conversion
- Minimize residual free acid content
- Ensure uniform melting and crystallization behavior
The finished material is typically supplied in solid or flake form for ease of handling and dosing.
Raw Material Origin
The product is derived from castor oil sourced from Indian castor seeds, processed through 12-Hydroxy Stearic Acid as an intermediate. Raw material consistency is critical for uniform ester properties and downstream performance.
In-House Quality Control & Consistency
Quality control focuses on parameters influencing ester purity, melting behavior, and stability. Each batch is monitored to ensure repeatable performance in formulation and processing applications.
Batch records and internal controls support traceability and long-term supply assurance.
