Product Introduction
1,2-Pentanediol (CAS No. 5343-92-0) is a diol organic compound with the molecular formula C5H12O2. It is a colorless, transparent liquid at room temperature. Its relative density is approximately 0.971, boiling point is 206°C, and flash point is 104°C. It is miscible with organic solvents such as alcohols, ethers, and ethyl acetate. As an important fine chemical intermediate, it possesses moisturizing properties, water solubility, and broad-spectrum antibacterial properties. Currently, the market supply covers various specifications including industrial, pharmaceutical, and cosmetic grades, and is gradually expanding from petroleum-based to environmentally friendly directions such as bio-based.
Overview
1,2-Pentanediol, also known as Pentylene Glycol, is a five-carbon aliphatic diol containing two hydroxyl groups located at the 1 and 2 positions of the carbon chain. As a multifunctional chemical ingredient, it combines excellent humectant performance, mild antimicrobial activity, solvent compatibility, and formulation stability, making it an important raw material in cosmetic, pharmaceutical, and specialty chemical industries.
With its balanced hydrophilic and lipophilic characteristics, 1,2-Pentanediol can effectively improve product texture, enhance ingredient solubility, and support the stability of various formulations. Qingdao Jinforest Chem Tech Co., Ltd. provides high-quality 1,2-Pentanediol with professional export service, complete documentation, and reliable supply capability to meet the needs of international customers.
Key Features and Advantages
One of the most important advantages of 1,2-Pentanediol is its outstanding moisture-retaining ability. The hydroxyl groups in its molecular structure allow it to attract and hold water molecules, helping maintain hydration balance in formulations.
For this reason, it is widely applied in skincare products such as creams, lotions, serums, and facial masks. Compared with traditional moisturizing agents, Pentylene Glycol provides a lightweight skin feel without excessive stickiness, improving the overall sensory experience of finished products.
In modern cosmetic formulations, manufacturers increasingly prefer multifunctional ingredients that can simplify formulas while improving performance. 1,2-Pentanediol meets this demand by acting as both a moisturizer and a formulation enhancer.
It can improve the dispersion of active ingredients, support preservative systems, and enhance the stability of cosmetic products. This makes it a valuable choice for personal care manufacturers developing high-quality skincare and beauty products.
1,2-Pentanediol has excellent compatibility with water, alcohols, and many organic compounds. This property allows it to function as an effective solvent and carrier in different chemical systems.
In pharmaceutical formulations, daily chemical products, and industrial applications, it helps dissolve functional ingredients more efficiently and improves the uniformity of final products.
Besides its moisturizing properties, 1,2-Pentanediol is recognized for its ability to provide antimicrobial support in cosmetic preservation systems. It can work together with other preservatives to help maintain product quality and extend shelf stability.
This feature makes it especially suitable for clean beauty formulations and products requiring gentle preservation strategies.
Qingdao Jinforest Chem Tech Co., Ltd. focuses on providing consistent chemical raw materials with strict quality management. Each batch of 1,2-Pentanediol can be supplied with professional quality documents, including COA (Certificate of Analysis), MSDS (Material Safety Data Sheet), and GHS-compliant labels.
Our quality control process includes raw material inspection, production monitoring, and finished product testing to ensure stable product performance and meet international purchasing requirements.
Applications of 1,2-Pentanediol
Cosmetics and Personal Care Products
1,2-Pentanediol is widely used in cosmetics as a highly effective moisturizer. It absorbs moisture and forms a water-locking film on the skin surface, improving dryness and roughness. It possesses broad-spectrum antibacterial activity, effectively inhibiting Gram-negative, Gram-positive, and fungal bacteria. It is often used as a preservative adjuvant to synergize with other preservative ingredients, helping formulations achieve the addition or reduction of traditional preservative dosages. Furthermore, it acts as a solvent for active ingredients, helping to dissolve poorly soluble components such as plant extracts and fragrances, while also improving the water resistance of sunscreen formulations, giving products a refreshing, non-sticky feel. Due to its mild and low-irritant properties, it is particularly suitable for use in infant products, sensitive skin care products, and formulations such as cleansers and masks.
Pesticides and Chemical Intermediates
1,2-Pentanediol is a key intermediate in the synthesis of the fungicide propiconazole. Propiconazole, as a low-toxicity, broad-spectrum systemic fungicide, plays an important role in the control of diseases in grain crops, vegetables, and fruits, and has a very broad market application prospect. Therefore, 1,2-pentanediol occupies an indispensable position in the pesticide manufacturing field.
Industry and Materials Manufacturing
In the industrial sector, 1,2-pentanediol can be used to produce polyester fibers and surfactants, and is also an important raw material for the synthesis of some pharmaceutical products. Due to its good solubility and stability, it is often used as a solvent and solubilizer in formulations, serving the material preparation and processing processes of downstream industries such as textiles and chemicals
