In 2025, the 11-Aminoundecanoic Acid market showed a mixed and slightly weak price trend, mainly influenced by changes in its key feedstock, castor oil. In the first quarter, the market remained relatively stable as firm castor seed costs and steady domestic demand supported production costs. Processing activity stayed consistent, and manageable inventories helped maintain balanced supply conditions. However, toward the end of the quarter, rising stock availability and softer export demand created downward pressure, leading to a gradual weakening in prices.
During the middle of the year, increased castor seed sowing and sufficient supply supported feedstock availability, which reduced production pressure and kept the market on a softer path. Export demand slowed, and industrial consumption from downstream sectors such as nylon and specialty chemicals remained moderate, limiting price growth. In the third quarter, steady seed inflows and adequate inventories continued to keep the market under pressure, although some stability was seen as supply and demand approached balance.
In the fourth quarter, prices showed mild recovery due to lower carry-forward stocks and weather-related crop concerns, but weak industrial demand and the end of the harvesting season kept the market stable overall.
Analyst Insight
According to Procurement Resource, the 11-Aminoundecanoic Acid market is expected to remain steady, with small fluctuations depending on the overall supply-demand dynamics and related fundamentals.

In 2024, the 11-Aminoundecanoic Acid market showed a fluctuating price trend, mainly driven by changes in its key feedstock, castor oil. Since 11-Aminoundecanoic Acid is produced from castor oil and castor seed derivatives, the availability and pricing of castor oil played an important role in shaping the overall market. During the first quarter, stable to slightly weak castor oil prices in India, supported by higher castor seed production and low international demand, kept the cost of production steady and limited strong price movement for 11-Aminoundecanoic Acid. The market remained calm with balanced supply and demand conditions.
In the second quarter of 2024, the prices reflected a volatile pattern. Castor seed acreage increased in the second quarter, which led to improved supply. This caused prices to dip in the short term. However, farmers started to regulate the supply to ensure prices remained stable. International castor oil supply also remained stable in the second quarter. This led to a slightly unstable pattern in the prices of 11-Aminoundecanoic Acid.
During the third quarter, reduced castor seed production in key Indian regions and supply chain issues led to tighter supply, which helped to support prices. Demand from industries like nylon, lubricants, and specialty chemicals helped to keep the market active.
During the fourth quarter, prices declined slightly, with stable demand from industries like cosmetics and pharmaceuticals, which did not increase prices. Weather-related damage to the crop, reduced seed availability, and supply issues caused some fluctuation in prices, but the overall trend remained stable.
Analyst Insight
According to Procurement Resource, the 11-Aminoundecanoic Acid market is expected to remain stable with mild fluctuations, depending on castor oil supply and demand from nylon and specialty chemical industries.
11-Aminoundecanoic acid is a white crystalline solid with low solubility in water. It belongs to the amines and fatty acids class and is an essential precursor of Nylon-11. On further treatment, the acid constitutes an important class of polyamides and fungicides. 11-aminoundecanoic acid is prepared from undecylenic acid derived from castor oil.

11-Aminoundecanoic acid is obtained through the pyrolysis of castor oil (ricinoleic acid) with water vapour at elevated temperatures and in the absence of air. Usually, the trans esterified product of ricinoleic acid, i.e., methyl ricinoleate, is made to undergo pyrolysis.
Methyl undecenoate and heptaldehyde thus obtained are subjected to further treatment. Methyl undecenoate is hydrolyzed to obtain undecanoic acid and then reacts with HBr forming bromoundecanoic acid. In the last step, the intermediate is treated with ammonia to get 11-aminoundecanoic acid.
