Opinions

How does China's propylene glycol supply structure differ from global producers, and what are the implications?

This rally is not purely cost-push. The data center liquid cooling narrative—especially Nvidia's shift to full liquid cooling using PG-based coolants—is adding a demand premium. Producers like Shida Shenghua and Haike Xinyuan are reportedly running at full capacity with minimal inventory, suggesting tightness may persist through 2026.

What is the current price trend for propylene glycol versus glycerin, and what factors are driving the divergence?

For buyers, route matters less than who owns the upstream. Integrated producers with captive PO or EO—like Weiyuan's propane-to-PO chain—can weather feedstock spikes better than merchant PG makers. When PO prices jump, non-integrated transesterification plants either pass through costs or cut runs, tightening supply further.

What is the outlook for China's 1,3-propanediol (PDO) market, and how does it differ from 1,2-PG?

The byproduct dependency cuts both ways. When PO-based DMC units idle due to poor DMC margins, PG supply falls even if PG demand is healthy. That structural mismatch explains why China swings between oversupply and acute tightness—and why the 2026 rally has been so violent.

How is the shift to Nvidia liquid cooling affecting demand for propylene glycol in China?

PDO and 1,2-PG should not be conflated in procurement. PDO's growth is tied to PTT fiber—carpets, textiles, automotive—while 1,2-PG follows unsaturated polyester resin, food/pharma, and now liquid cooling. The price trajectories are diverging: PDO is heading down on import substitution, while 1,2-PG is spiking on supply tightness.

Overview

Propylene glycol (1,2-propanediol, CAS 57-55-6) is a colourless, viscous, nearly odourless liquid miscible with water and many organic solvents. It is a low-toxicity, versatile chemical used across food, cosmetics, and industrial application.

Food: acts as a stabiliser, humectant, emulsifier, anti-caking agent, and thickener in products like pastries and wet noodles.
Cosmetics & personal care: a moisturiser in toothpaste, soaps, and skincare products.
Industrial: raw material for unsaturated polyester resins, polyethers, and antifreeze; also used as a coolant in data-centre liquid cooling systems.
Pharmaceuticals: used as a solvent and excipient.

China's production is mainly industrial-grade, with a surplus historically balanced by exports; high-purity food and pharmaceutical grades are also produced domestically. Manufacturing routes are based on propylene oxide, with some carbonate units being converted to produce propylene glycol. Domestic supply has tightened recently due to strong export demand.

Key domestic producers:
Shida Shenghua – food and pharmaceutical grade.
Haike Xinyuan – pharmaceutical excipient grade.
Wanhua Chemical (Penglai) – planning to convert a DMC unit to produce propylene glycol.
Weiyuan Co. – active in new materials and energy-related operations.
