SunSirs: With Increased Production and Rising Costs, the Price of Isooctanol Fluctuated Upwards in January

January 20 2026 08:58:47     SunSirs (John)

In January, the price of isooctanol fluctuated and rose

According to SunSirs' commodity price analysis system, as of January 16th, the price of isooctanol was 7,033.33 RMB/ton, a fluctuating increase of 1.69% compared to the price of 6,916.67 RMB/ton on January 1st. Isooctanol manufacturers had completed equipment maintenance, leading to increased operating rates and ample supply of isooctanol (operating rate at 95%). The strong increase in propylene prices provided greater cost support for isooctanol. The fluctuating increase in plasticizer prices had also provided greater downstream demand support for isooctanol. Despite increased costs and supply, and relatively weak downstream support, the price of isooctanol had shown a fluctuating upward trend.

Isooctanol manufacturers were increasing production

Isopropanol manufacturers increased production, with domestic isopropanol manufacturers operating at around 95% capacity. Domestic weekly production of isopropanol was 76,000 tons. The increase in isopropanol production and supply had weakened the upward momentum of isopropanol prices.

The cost of the raw material, propylene, increased significantly

According to the business data analysis system of SunSirs, as of January 16th, the price of propylene was 6,147.67 RMB/ton, a significant increase from the price of 5,717.67 RMB/ton on January 1st, representing a 7.52% increase. The significant increase in propylene prices in January was driven by rising raw material costs, leading to increased production costs for isooctanol and providing strong support for higher isooctanol prices.

Downstream plasticizer DOP prices fluctuated upwards

According to the business data analysis system of SunSirs, as of January 16th, the price of DOP was 7,492.50 RMB/ton, a fluctuating increase compared to the price of 7,325.84 RMB/ton on January 1st, with a rise of 2.27%. The cost of DOP had increased, and the operating rate of DOP manufacturers remained stable at around 63%, resulting in stable DOP production. The demand for isooctanol remained strong, providing significant support for the price increase of isooctanol.

Market Forecast:

According to the data analyst for octanol products at SunSirs, in terms of costs, the significant increase in the price of propylene, a raw material, boosted the upward momentum of isooctanol prices. Regarding supply, the operating rate of isooctanol enterprises had increased, leading to an increase in isooctanol supply. In terms of demand, the operating rate of DOP (dioctyl phthalate) enterprises remained stable, resulting in stable DOP production, thus maintaining support for isooctanol demand. Looking ahead, while increased cost support and increased supply coupled with limited demand support created downward pressure on isooctanol prices, upward support still existed.  Therefore, the market is expected to see isooctanol prices fluctuate and stabilize.
