Ethylene Oxide Market Global Report 2026

The ethylene oxide market size has grown strongly in recent years. It will grow from $29.8 billion in 2025 to $32.55 billion in 2026 at a compound annual growth rate (CAGR) of 9.2%. The growth during the historic period can be attributed to increasing production of ethylene glycol and chemical derivatives, rising demand for medical device sterilization, growing healthcare and pharmaceutical manufacturing, expanding use of surfactants and specialty chemicals, and increasing consumption of industrial chemical intermediates.

The ethylene oxide market size is expected to see strong growth in the next few years. It will grow to $45.57 billion in 2030 at a compound annual growth rate (CAGR) of 8.8%. The growth during the forecast period can be attributed to increasing demand for sterilization of heat-sensitive medical products, rising need for high-purity ethylene oxide, growing production of ethylene oxide-based polymers and surfactants, expanding pharmaceutical and healthcare manufacturing capacity, and increasing demand for specialty chemical derivatives. Major trends during the forecast period include increasing demand for ethylene oxide as a chemical intermediate, rising demand for ethylene oxide-based chemical derivatives, growing adoption of ethylene oxide sterilization for heat-sensitive products, increasing need for high-purity ethylene oxide in industrial applications, and expanding use of ethylene oxide in surfactant and polymer production.

The growing demand for polyester fibers is expected to propel the growth of the ethylene oxide market going forward. Polyester fibers are synthetic fibers widely used in textiles, apparel, home furnishings, and industrial applications because of their durability, affordability, and resistance to shrinking and wrinkling. Demand for polyester fibers is increasing due to the expansion of the fast-fashion industry, where brands manufacture large volumes of low-cost and frequently changing clothing collections, with polyester being preferred because it is inexpensive, durable, easy to manufacture at scale, and suitable for rapid mass production. Polyester fibers depend on high-purity ethylene oxide (EO) as an important upstream raw material because EO is converted into monoethylene glycol (MEG), which is subsequently polymerized with purified terephthalic acid (PTA) to produce polyethylene terephthalate (PET). For instance, in September 2025, according to Textile Exchange, a US-based non-profit organization, global polyester fiber production increased by volume from approximately 71 million tonnes in 2023 to around 78 million tonnes in 2024. Therefore, the growing demand for polyester fibers is driving the growth of the ethylene oxide market.

Major companies operating in the ethylene oxide market are concentrating on developing innovative products, such as ethylene oxide (EtO) emission control systems, to improve environmental safety, regulatory compliance, and worker protection in sterilization facilities. Ethylene oxide emission control systems are advanced air purification technologies designed to capture and destroy fugitive EtO emissions from industrial environments, helping reduce hazardous air pollutants, improve workplace safety, and achieve higher removal efficiency compared with conventional ventilation or filtration technologies. For instance, in June 2025, Sonata Scientific Inc., a US-based industrial air purification company, launched the Helios MP500, an innovative ethylene oxide emission control system for medical device sterilization facilities. The standalone, ductless system operates at 500 cubic feet per minute (cfm) and provides destruction and removal efficiency (DRE) of more than 99%, effectively eliminating fugitive EtO emissions, including concentrations at parts-per-billion levels. Validated in real-world environments, the Helios MP500 is designed for scalable deployment and supports safer operations by reducing worker and community exposure while helping facilities meet stringent environmental requirements.

In December 2023, INEOS Group Holdings S.A., a UK-based petrochemicals and specialty chemicals manufacturer, agreed to acquire LyondellBasell Industries N.V.’s Ethylene Oxide and Derivatives business and Bayport production facility for $700 million.
