Undecylenic Acid Market Summary
Introduction
The undecylenic acid market centers on the production and application of undecylenic acid, also known as 10-undecenoic acid or undecylenic acid, with CAS number 112-38-9. This versatile eleven-carbon unsaturated fatty acid is characterized by its unique antifungal properties and serves as a crucial intermediate in the synthesis of various high-value chemicals. Undecylenic acid is primarily recognized as an important raw material for synthetic fragrances, used in the production of γ-undecalactone (peach aldehyde), polycyclopentadecanolide, muscone, nonaldehyde, and nonanol. Its inherent ability to inhibit fungal reproduction makes it valuable as a disinfectant and antiseptic agent, particularly effective in treating athlete's foot, ringworm, jock itch, and fungal vaginitis, with athlete's foot treatment showing the highest efficacy. As a pharmaceutical antifungal agent, it is typically used in concentrations ranging from 2% to 15% by weight, while in cosmetics applications, the maximum allowable concentration is 0.2% by weight, remaining stable within a pH range of 5.0 to 6.5. The compound also finds applications in plasticizer production and other industrial processes. The market has witnessed significant capacity expansion, notably with Arkema's completion of a large-scale bio-based facility in Jurong Island, Singapore in 2022, increasing its Oleris high-performance bio-based oleochemicals global capacity by 50%. The Oleris product line encompasses C7, C11, and C18 series, including n-heptanoic acid, n-heptanal, undecylenic acid, and Esterol A products.
