1,2-Pentanediol, also known as pentylene glycol, is a diol compound with a straight-chain carbon backbone. It consists of two hydroxyl (OH) groups attached to different carbon atoms. The chemical is a colorless, viscous liquid with a mild odor. It is miscible with water and various organic solvents, making it a versatile ingredient in different applications. The compound is produced through advanced synthesis methods, ensuring high purity and consistent quality.


1,2-Pentanediol is widely used in the personal care industry, particularly in the formulation of cosmetics, skincare products, and hair care items. Its humectant and emollient properties make it effective in attracting and retaining moisture, providing hydration and a soft, smooth feel to the skin and hair. Additionally, it contributes to the stability and sensory attributes of the formulations, enhancing the overall user experience.

Industrial Applications:

In industrial applications, 1,2-Pentanediol serves as a solvent and coalescing agent in various chemical processes, including paint and coatings formulations. As a solvent, it aids in dissolving and transporting reactants during synthesis reactions. As a coalescing agent, it promotes the merging of polymer particles during the drying process, leading to improved adhesion and durability of the coatings.

Antimicrobial and Preservative:

1,2-Pentanediol exhibits antimicrobial properties and is utilized as a preservative in certain cosmetic and personal care products. It helps prevent the growth of bacteria, molds, and yeasts, thus extending the shelf life of the products.
