Six Facts You Need to Know About 1,6-Hexanediol

1,6-Hexanediol, also known as Hexamethylene glycol, 1,6-Dihydroxyhexane, 1,6-Hexylene Glycol, 1,6-HDO is a white waxy solid at room temperature, the state is shown below. When the temperature is higher than the melting point (42 ℃) above the colourless transparent liquid, boiling point 250 ℃, soluble in water, methanol, butanol, butyl acetate, slightly soluble in hot ether insoluble in benzene. It is an important chemical raw material, one of the important raw materials for many kinds of organic synthesis.

Is 1,6-Hexanediol Used in the Production of Polyurethane?

Yes, 1,6-Hexanediol plays a crucial role in the production of polyurethane polymers. It is widely utilized as one of the key components in the synthesis process, contributing to the desirable properties of the final product.

First and foremost, 1,6-Hexanediol imparts flexibility, strength, and durability to polyurethane. When incorporated into the polymer formulation, it helps enhance the material's ability to withstand mechanical stress, such as bending or stretching, without losing its integrity. This characteristic is particularly important in applications where flexibility and resilience are desired, such as in the production of elastomers or flexible foams.

Furthermore, 1,6-Hexanediol can also function as a chain extender or crosslinker in polyurethane formulations. As a chain extender, it reacts with the polymer chains, increasing their length and contributing to the overall molecular structure of the material. This process enhances the mechanical properties and performance of the polyurethane, including its tensile strength and resistance to wear and tear.

Additionally, as a crosslinker, 1,6-Hexanediol forms chemical bonds between different polymer chains, creating a three-dimensional network within the polyurethane structure. This crosslinking process improves the material's dimensional stability, heat resistance, and chemical resistance, making it suitable for applications that require high-performance characteristics, such as coatings, adhesives, and sealants.

1,6-Hexanediol is a vital component in the production of polyurethane. Its inclusion in the synthesis process contributes to the flexibility, strength, and durability of the final product. Moreover, it can act as a chain extender or crosslinker, further enhancing the performance and properties of polyurethane materials.

Is 1,6-Hexanediol Flammable?

1,6-Hexanediol exhibits flammable properties, as indicated by its flash point of approximately 110 °C. A flash point is the temperature at which a substance can produce enough vapor to ignite in the presence of an open flame or other sources of ignition. Given the flammable nature of 1,6-Hexanediol, it is crucial to store and handle it with utmost caution.

To ensure safety, it is recommended to store 1,6-Hexanediol in well-ventilated areas away from open flames, sparks, or any potential sources of ignition. Additionally, when handling this chemical, it is advisable to use appropriate safety measures, such as wearing protective gear like gloves and goggles.


Understanding the flash point is essential for assessing the fire hazard associated with a substance. In the case of 1,6-Hexanediol, its flash point of 110 °C implies that it is susceptible to ignition at relatively elevated temperatures. Therefore, users should be aware of and adhere to proper storage and handling practices to mitigate the risk of fire.

1,6-Hexanediol is considered flammable due to its flash point of approximately 110 °C. It is imperative to handle and store this chemical with caution, taking necessary precautions to prevent potential ignition and ensuring the overall safety of the handling environment.

Is 1,6-Hexanediol Toxic?

1,6-Hexanediol is a chemical compound that is commonly used in various industries, including cosmetics, pharmaceuticals, and industrial applications. It is primarily used as a solvent, humectant, and viscosity agent. When it comes to toxicity, 1,6-Hexanediol is generally regarded as having low toxicity.

The low toxicity of 1,6-Hexanediol means that it is unlikely to cause harm or pose significant health risks when used properly. However, it is important to handle this chemical with care and follow appropriate safety measures. This includes storing it in a secure and well-ventilated area, using personal protective equipment such as gloves and goggles when handling it, and following any specific safety guidelines provided by the manufacturer.

It's worth noting that the toxicity of a chemical can vary depending on factors such as concentration, route of exposure (e.g., inhalation, ingestion, or skin contact), and individual sensitivity. While 1,6-Hexanediol is generally considered to have low toxicity, it is always advisable to consult safety data sheets (SDS) or seek guidance from professionals familiar with the specific application and usage of the chemical.

1,6-Hexanediol is generally considered to have low toxicity. However, as with any chemical, it is important to handle it responsibly, follow safety guidelines, and take necessary precautions to ensure safe usage and minimize any potential risks.

Is 1,6-Hexanediol Biodegradable?

1,6-Hexanediol is indeed biodegradable, signifying that it can naturally decompose over time through biological processes. This characteristic renders it environmentally friendly when compared to certain other chemicals utilized in analogous applications.

The biodegradability of 1,6-Hexanediol is a significant advantage, as it suggests that once released into the environment, it can be broken down by bacteria, fungi, or other organisms, ultimately reducing its impact on ecosystems. This property aligns with the growing emphasis on sustainable and eco-friendly practices within various industries.

Furthermore, the biodegradability of 1,6-Hexanediol underscores its potential for use in applications where environmental impact is a concern, as it offers a more sustainable alternative to non-biodegradable substances. This aspect contributes to the overall efforts to minimize the ecological footprint of industrial and commercial activities.

The biodegradable nature of 1,6-Hexanediol underscores its environmentally friendly profile, as it can be naturally broken down over time through biological processes, distinguishing it as a more sustainable option in various applications.


How 1,6-Hexanediol Is Stored?

1,6-Hexanediol should be stored in a cool, dry, and well-ventilated area. It should be kept away from sources of ignition, heat, and direct sunlight. It is recommended to store it in tightly sealed containers, preferably made of glass or high-density polyethylene (HDPE), to prevent leakage or evaporation. Proper labeling should be used to clearly identify the contents and any associated hazards. It is also important to store 1,6-Hexanediol away from incompatible materials and keep it out of reach of children or unauthorized personnel. Following these storage guidelines will help ensure the stability and safety of the compound.

How 1,6-Hexanediol Is Transported?

1,6-Hexanediol is typically transported in bulk quantities or in smaller containers such as drums or intermediate bulk containers (IBCs). The transportation of 1,6-Hexanediol follows regulations and guidelines set by local, national, and international authorities to ensure safety.

During transportation, 1,6-Hexanediol should be properly packaged and secured to prevent leakage or spillage. It should be transported in approved containers made of materials compatible with the chemical, such as glass or HDPE.
