The use of 1,3-propanediol is growing exponentially across various industries around the world owing to its versatility and eco-friendly nature. 1,3-Propanediol, also known as trimethylene glycol, is a valuable chemical building block derived from renewable feedstocks that can be used to produce a wide range of products. In this article, we analyze the major factors fueling the expansion of the global 1,3-propanediol market.

Booming Polytrimethylene Terephthalate Production
One of the biggest drivers of 1,3-propanediol demand is its use in producing polytrimethylene terephthalate (PTT). PTT is a sustainable synthetic fiber that is used to manufacture fabrics, textiles, carpets and various other materials. It offers properties comparable to nylon but is more environmentally friendly as it is biodegradable. Over the past decade, PTT production has grown exponentially due to tightening environmental regulations and increasing consumer preference for eco-friendly products. As a result, there has been a consistent rise in the consumption of 1,3-propanediol that is used as a raw material in PTT manufacturing. Most industry experts project this trend to continue well into the future.

Rising Demand from Polyester Resins Applications
Unsaturated polyester resins are a type of thermosetting plastic polymers widely used in fiberglass, construction materials, vehicle components and many other areas. Production of unsaturated polyester resins involves using  1,3 Propanediol as a base chemical. With infrastructure and construction activities booming in developing nations, demand for materials like fiberglass has increased manifold. This has significantly driven up global needs for 1,3-propanediol that finds its way into polyester resin synthesis. Auto component manufacturers as well are major consumers of unsaturated polyester resins and indirectly 1,3-propanediol. Rapid motorization of emerging economies will ensure sustained demand kinetics in the foreseeable future.

Growing Uptake in Cosmetics and Personal Care Products
Another noteworthy application that has emerged over the years is the usage of 1,3-propanediol in cosmetics and personal hygiene items. It is commonly utilized as a humectant or moisturizing agent in products like creams, lotions, soaps and deodorants. Some major benefits include ability to retain moisture, bring softness to the skin and lowering pH levels. With rising incomes, awareness and globalization, international cosmetics market has been growing at a healthy rate, particularly in Asia Pacific nations. This has boosted consumption of 1,3-propanediol that provides formulation advantages over other humectants. Expanding middle class population will augment demand from this application domain.

Rising Clout of Bio-Based Production
Earlier, 1,3-propanediol was predominantly produced from fossil fuel-based sources like ethylene oxide or acrolein. However, in recent times bio-based production from renewable resources like sugarcane, corn or refined glycerin has gained notable traction. This transition was driven by aspects like volatile crude oil prices, environmental regulations and consumer inclination for green chemicals. Today, majority of 1,3-propanediol manufacturing capacity uses fermentation or chemical processes that involve bio-feedstocks. This has offered advantages such as cost stability, supply security and more favorable perception in the market. As sustainability becomes an increasingly important agenda, bio-based variants will further reinforce their place and play a key role in advancing the industry landscape.

Asia Pacific as a Hotspot
When analyzed regionally, Asia Pacific holds an outstanding position and captured over 50% of global 1,3-propanediol market share in 2020. This was prominently owing to massive PTT, polyester production and construction investments happening in the region combined with growing usage in personal care sector. China represents the largest consumer base, while others like India, Taiwan, Indonesia and Vietnam showcase promising opportunities. North America and Europe also contribute notably to overall commercial activity, but emerging regions in developing Asia and Latin America will be the new hotspots that drive future volumes higher. Overall, the worldwide 1,3-propanediol industry prospects appear bright with annual capacity additions and innovative applications on the anvil.

1,3-propanediol is a crucial industrial commodity that finds widespread uptake backed by advantageous physicochemical properties. The global market is witnessing healthy expansion powered by multiple factors ranging from material manufacturing growth to rising intermediate consumption and increasing focus on eco-friendliness. With sustainable socioeconomic trends reinforcing product demand trends, the business potential of 1,3-propanediol market is set to amplify further on a global scale over the long run. Ongoing research efforts striving to optimize production technologies and discover new use areas will strengthen the industry outlook substantially.
