Mineral Oil Defoamer Market Intelligence Report (May 2026)

I. Price Dynamics
1. Domestic Market Quotations
– Henan Kaijie Water Treatment Co., Ltd.:
100% active content mineral oil defoamer: RMB 17,500 per metric ton
80% active content mineral oil defoamer: Not explicitly quoted; however, reference can be drawn from comparable products—e.g., esterified polyether defoamer (80% active content) priced at RMB 16,800 per metric ton
– Quotation range from other manufacturers:
Low-concentration products (6–20% active content): RMB 3,200–5,300 per metric ton
High-concentration products (≥90% active content): RMB 2,600–17,500 per metric ton

2. Key Price Volatility Drivers
– Raw Material Costs: Base mineral oil prices are influenced by international crude oil market fluctuations; however, the domestic self-sufficiency rate of low-aromatic, high-flash-point base oils has risen to 63.8%, partially alleviating cost pressure.
– Environmental Regulations: The newly implemented national standard GB/T 43286-2025 tightens VOC limits from 350 g/L to 150 g/L, prompting formulation upgrades across the industry and potentially increasing short-term production costs.
– Supply–Demand Balance: Industry capacity utilization reached 86.7% in 2025, supported by steady, inelastic downstream demand (e.g., in papermaking and coatings), contributing to price stability.

II. Supply–Demand Analysis
1. Supply Side
– Production Capacity & Output: China’s actual output of mineral oil defoamers reached 32,800 metric tons in 2025, up 14.3% year-on-year, with capacity utilization significantly exceeding the industry average.
– Market Structure:
CR5 (top five enterprises) market share increased to 46.8%; leading players—including CNOOC Energy Development and Jiangsu Flying Chemical—have consolidated their advantages through technological iteration and supply chain integration.
SMEs face mounting margin pressure (industry average gross margin: 27.9%), and some price-driven manufacturers are gradually exiting the market.

2. Demand Side
– Downstream Applications:
Core application segments: metalworking fluids (38%), coatings & inks (29%), and papermaking (15%).
Emerging applications—including lithium-ion battery separator coating and biopharmaceutical fermentation—now account for 6% of total demand, exhibiting notably higher growth rates.
– Regional Markets:
Domestic demand remains steadily robust: the 2025 market size reached RMB 1.932 billion, growing 6.8% year-on-year.
Export markets have emerged as a new growth driver: export value totaled RMB 217 million in 2025, up 11.3% YoY, primarily directed toward Southeast Asia and the Middle East.

III. Technological Trends & Product Upgrades
1. Eco-Friendly Products:
– Low-VOC and high-biodegradability formulations have become mainstream; the biodegradation rate of leading commercial products reached 73.2% in 2025—exceeding the regulatory minimum threshold (≥60%).
– Leading enterprises have launched composite mineral oil defoamers (e.g., incorporating modified silica aerogel dispersions), extending foam suppression duration by 40% to meet high-end customer requirements.

2. Customization Services:
– Companies are building proprietary emulsion stability databases and offering dedicated technical support teams to enable rapid product iteration (e.g., formulation adjustments completed within 72 hours).
– Case Study: Dongguan Antai Fine Chemical Co., Ltd. developed a low-odor mineral oil defoamer for Kezhijie Group, resolving phase separation issues under high-humidity summer conditions, with VOC content <1,000 mg/kg.

IV. Outlook (2026–2028)
1. Price Trend Forecast:
– Short Term (6–12 months): Prices are expected to remain elevated and volatile due to environmental compliance costs and raw material price fluctuations; however, top-tier enterprises—leveraging economies of scale and integrated supply chains—are projected to maintain gross margins above 32%.
– Long Term (2–3 years): As domestic substitution advances (e.g., low-aromatic base oil self-sufficiency projected to exceed 70%), cost pressures will ease, allowing prices to gradually return to rational levels.

2. Key Growth Drivers:
– Papermaking Industry: Bamboo-for-wood technology upgrade initiatives are driving demand for highly compatible defoamers, expected to generate ~RMB 120 million in incremental market value in 2026.
– Textile Printing & Dyeing: Green standard enhancements are accelerating replacement demand for low-VOC formulations; penetration of composite mineral oil defoamers is expected to rise to 35%.
– Export Markets: Deepening RCEP origin rules and enhanced localized technical service capabilities are projected to lift the export contribution ratio to 12.4% in 2026.

3. Competitive Landscape Evolution:
– Industry concentration will continue rising, with CR5 market share likely surpassing 50%; SMEs are accelerating their strategic shift toward niche segments (e.g., food-grade or high-temperature long-lasting formulations).
– Technical barriers are becoming the core competitive differentiator; enterprises holding dual ISO 9001/ISO 14001 certification and possessing independent R&D capabilities will dominate the market.
