Castor Oil C-11 Derivatives

Manufactured by Nova Industries

Nova Industries specializes in the high-temperature Pyrolysis (Cracking) of Castor Oil to produce the C-11 Series of oleochemicals.

When Ricinoleic Acid (or its Methyl Ester) is subjected to thermal decomposition at $>450^\circ C$, it cleaves into two primary fragments: the volatile C-7 aldehyde (Heptaldehyde) and the long-chain C-11 unsaturated fragment. This C-11 chain is the foundation for high-performance biopolymers (Nylon-11) and FDA-approved antifungals.

1. Undecylenic Acid

The Biopolymer & Pharma Precursor

Undecylenic Acid is an unsaturated fatty acid (10-undecenoic acid) produced via the hydrolysis of Methyl Undecylenate or direct pyrolysis.1

• Polyamide-11 (Nylon-11): This is the single largest industrial application. Undecylenic Acid is chemically modified (via hydrobromination and amination) to produce 11-Aminoundecanoic Acid, the monomer for Nylon-11.² This high-performance polymer is used in automotive fuel lines, pneumatic tubing, and offshore oil pipes due to its exceptional toughness and chemical resistance.³
• Pharmaceuticals: FDA-approved as a topical antifungal agent.⁴ It is used to treat dermatomycoses (Athlete’s Foot, Ringworm) due to its ability to disrupt fungal cell membrane formation.⁵
• Perfumery: Used as a precursor for synthetic musks and antibacterial deodorizers.⁶

2. Methyl Undecylenate

The Primary Intermediate

Methyl Undecylenate is the methyl ester of Undecylenic Acid, typically produced directly by the pyrolysis of Methyl Ricinoleate.

• Purity Advantage: Cracking the methyl ester (rather than the oil) yields a cleaner product profile.
• Applications:
  • Chemical Intermediate: The starting material for manufacturing Undecylenic Acid (via hydrolysis) and Nylon-11 monomers.
  • Fragrance & Flavors: Used in perfumery for its honey-like, waxy odor profile.
  • Formulations: Acts as a chemical intermediate in cosmetic formulations requiring anti-odor properties.⁷

3. Undecanoic Acid

The Saturated C-11

Undecanoic Acid (Undecylic Acid) is the saturated derivative produced by the hydrogenation of Undecylenic Acid.

• Applications:
  • Nylon Precursor: Products like Amino-Undecanoic Acid serve as precursors for Nylon-11 via self-polycondensation.⁸
  • Fragrance: Used as a chemical intermediate for the manufacture of esters used in flavors and perfumes.⁹
  • Dermatology: Used as an active principle in ointments with dermatophilic activity.

4. Zinc Undecylenate

The Antifungal Salt

Zinc Undecylenate is the Zinc salt of Undecylenic Acid.10

• Synergistic Action: It is often combined with free Undecylenic Acid in pharmaceutical preparations. The Zinc salt provides astringent properties (drying out the skin) while the acid attacks the fungus.
• Stability: Reports indicate it is highly stable and provides sustained release of the active fatty acid.
• Uses: The primary active ingredient in antifungal powders, creams, and ointments for relieving itching, burning, and superficial fungal infections.¹¹
