Polyethyleneimine Market Analysis & Forecast: 2025-2032

Polyethyleneimine Market is estimated to be valued at USD 459.2 Mn in 2025 and is expected to reach USD 568.6 Mn in 2032, exhibiting a compound annual growth rate (CAGR) of 3.1% from 2025 to 2032. The term polyethyleneimine is also known as polyaziridine. Polyethyleneimines consist of a repeating unit with a cyclic amine group and two aliphatic carbon CHâ‚‚CHâ‚‚  spacers. Linear polyethyleneimines have all secondary amine groups, while branched polyethyleneimines contain primary amino groups.

Covid-19 Impact on Global Polyethyleneimine Market

The COVID-19 pandemic has had a significant impact on the global polyethyleneimine market. Polyethyleneimine is a versatile polymer that is used in a wide range of applications, including water treatment, paper production, and biomedical research. The pandemic has disrupted supply chains, reduced demand, and caused significant economic uncertainty, all of which have affected the polyethyleneimine market. One of the main impacts of the pandemic on the polyethyleneimine market has been a reduction in demand. Many industries that use polyethyleneimine, such as the paper and textile industries, have been hard hit by the pandemic, leading to a decrease in demand for the polymer. Additionally, the closure of many businesses and factories has disrupted supply chains, making it difficult for manufacturers to obtain the raw materials needed to produce polyethyleneimine.

Global Polyethyleneimine Market - Drivers

• Growing demand from detergents

Growing demand from detergents is primarily fueling growth of the polyethyleneimine market. Polyethyleneimine is used in detergent compositions for enhanced stain removal. Detergent compositions containing polyethyleneimine provide enhanced removal of organic stains, particularly polyphenolic stains such as morello juice (cherry juice), blueberry juice, red wine, tea, and coffee.

• Increasing demand from water treatment chemicals

Increasing demand for water treatment chemicals is again projected to foster market growth. According to UNICEF, about 4 billion people, or approximately two-thirds of the world's population, experience water scarcity for at least one month each year. More than 2 billion people live in countries where water supplies are scarce. Half of the world's population could be living in areas facing severe water shortages in 2025, with 700 million people being displaced by intense water scarcity by 2032. Therefore, water treatment has become necessary over the years.

Global Polyethyleneimine Market - Restraints

• Strict environmental regulations

Strict environmental regulations are expected to hinder growth of the global polyethyleneimine market. According to the Environmental Protection Agency (EPA), acute inhalation exposure to ethyleneimine causes respiratory tract irritation and inflammation in humans, but symptoms may be delayed for several hours. Some symptoms of acute inhalation exposure in humans include tearing and burning of the eyes, a sore throat, nasal secretion, bronchitis, shortness of breath, and edema of the lungs.

The availability of substitutes such as silanes, maleic anhydride, titanates, zirconates, and others pose a threat to the polyethyleneimine market as they are more likely used as adhesion promoters in the adhesives industry.

Global Polyethyleneimine Market - By Segmentation

The branched segment currently has the largest market share, with 73.40% of revenue in 2025. The polymer known as branched polyethyleneimine (BPEI) is made up of repeating units of ethylene diamine groups. BPEIs are solids and contain primary, secondary, and tertiary amino groups. The primary amines on BPEIs are used to form covalent connections with carboxyl-functionalized nanoparticles, resulting in a firm, strongly positively charged BPEI surface. By effectively acting as a crosslinker, they improve the tensile strength, cohesiveness, and moisture resistance of adhesives, paints, coatings, etc.

Global Polyethyleneimine Market - Opportunities

• Increasing development of polyethyleneimine-nano silica composites

The increasing development of polyethyleneimine-nanosilica composites is expected to offer lucrative opportunities in the market. For instance, scientists are focusing on developing novel solvents and solvent combinations exhibiting lower volatility, better thermal stability, lower corrosive characteristics, a lower degradation rate, and reduced regeneration costs. Adsorption by polyethyleneimine nano-silica composites, such as SBA-15-supported PEI and MCM-41 - supported PEI, constitutes an attractive solution owing to minimal utilization of regeneration energy, high capture capacity and selectivity, processing convenience, cost-effectiveness, and reduced environmental impact.

• Rapid growth in personal care and cosmetic industry

Rapid growth in the personal care and cosmetic industries is expected to bring profitable growth opportunities. According to Invest India, India's beauty and personal care product industry is currently valued at USD 26.8 billion and is expected to grow to USD 37.2 billion by 2025. According to Forbes India, the beauty and personal care industries received USD 264 million in financing in the seven months ending July 2021, up from USD 106 million in the entire year of 2021.

Global Polyethyleneimine Market - Trends

• Increasing demand from construction industry and rise in construction activities

Increasing demand from the construction industry and a rise in construction activities are expected to be trends in the market. As per the statistics provided by the U.S. Census Bureau and the U.S. Department of Housing and Urban Development, privately owned residential units authorized by building permits were at a seasonally adjusted annual rate of 1,873,000 in December 2021. Single-family permits were granted at a rate of 1,128,000 per year. Unit authorizations in structures with five or more units were at an annual rate of 675,000. Building permits approved an expected 1,724,700 housing units in 2021. This number was 17.2% higher than the 2021 forecast of 1,471,100.

• Penetration of electric vehicle

The penetration of electric vehicles is expected to boost market growth. According to International Energy Agency, in 2030, global electric vehicle sales are expected to reach 125 million as per the New Policies Scenario (excluding two- and three-wheelers). In the EV30@30 Scenario, in 2030, around 70% of the vehicle sales in China are expected to be EVs.

Global Polyethyleneimine Market - Regional Analysis

Asia Pacific held a dominant position in the global polyethyleneimine market in 2025, accounting for 54.70% share in terms of volume, followed by North America and Europe, respectively.
