SunSirs: Cost Reduction and Weak Demand, the Price of Isooctanol Fluctuated and Fell
October 29 2025 14:22:33SunSirs(John)

The price of isooctanol fluctuated and fell

According to the SunSirs commodity market analysis system, as of October 27, the price of isooctanol was 5,883.33 RMB/ton, a 6.37% decrease from the previous week's price of 6,283.33 RMB/ton on October 20. Due to maintenance on some companies' isooctanol equipment, the operating rate of isooctanol plants had slightly decreased, with the utilization rate below 90%, resulting in a decrease in isooctanol supply. Propylene prices had fallen, reducing isooctanol costs. This cycle, weak supply and demand for isooctanol, coupled with falling costs, had led to a volatile decline in isooctanol prices.

The cost of raw material propylene decreased

According to the SunSirs commodity market analysis system, as of October 27, the price of propylene was 6,158.25 RMB/ton, a 0.61% decrease from 6,195.75 RMB/ton on October 20. This cycle's propylene price saw a volatile decline, driven by falling raw material prices and lower isooctanol costs, which intensified downward pressure on isooctanol prices.

Downstream plasticizer DOP prices fluctuated and fell

According to the SunSirs Commodity Market Analysis System, as of October 27, the price of DOP was 7,109.16 RMB/ton, a 1.39% decrease from the price of 7,209.17 RMB/ton on October 20. DOP prices fluctuated downward this cycle, with DOP companies operating at less than 60% capacity, a slight decline in operating rates. This decline in DOP production, coupled with declining demand for isooctanol, puts significant downward pressure on isooctanol prices.

Market outlook

Octanol product data analysts at SunSirs believe that falling propylene and raw material prices were increasing downward pressure on isooctanol prices. On the supply side, the operating rate of isooctanol plants was less than 90%, and this decline was leading to a decrease in isooctanol supply. On the demand side, DOP prices were fluctuating downward, DOP plant operating rates were slightly down, and DOP production was declining, reducing demand support for isooctanol. In the future market, the cost of isooctanol will drop, and coupled with weak supply and demand, the downward pressure on isooctanol will increase. It is expected that the price of isooctanol will fluctuate and fall in the future market.
