1,2-Pentanediol is a globally approved multifunctional cosmetic additive with broad-spectrum antibacterial activity. It offers high formulation flexibility, is unaffected by hydrolysis, temperature, and pH, and is widely used in both no-rinse and rinse-off products. When combined with traditional preservatives and additive-free preservatives, it exhibits significant synergistic effects. It is also used as a emollient and humectant, providing both preservative and moisturizing benefits while improving the skin feel of the product. Compared to other antibacterial agents, it is gentler, safer, and less irritating. It complies with cosmetic regulations in the United States, Europe, and Japan.

1,2-Pentanediol is primarily used in the production of the fungicide propiconazole intermediate and surfactants. In cosmetics, it serves as a preservative and moisturizer, improving the water resistance of sunscreen formulations. It is used in skin creams, sunscreens, and baby care products.

1,2-Pentanediol is a commonly used moisturizer widely found in cosmetics and skincare products. Its main function is to increase skin hydration, making skin softer, smoother, and more elastic. It helps the skin absorb moisture, preventing moisture loss and maintaining skin's moisture balance. Furthermore, 1,2-Pentanediol possesses antibacterial and anti-inflammatory properties, reducing skin infections and inflammation. At appropriate concentrations, 1,2-Pentanediol is safe for the skin and will not cause harm.

1,2-Pentanediol is a straight-chain diol with distinct polarity and non-polarity, giving it properties different from other diols. This unique charge distribution explains its unique characteristics and multifunctionality.
