1,2-Pentanediol is an important organic intermediate used in the synthesis of propiconazole, a fungicide specifically for economic crops. It also possesses excellent moisturizing and preservative properties, making it suitable for various skincare products such as creams, eye creams, lotions, baby care products, and sunscreens. Furthermore, it is a crucial raw material for the production of polyester fibers, surfactants, and pharmaceuticals.
1,2-Pentanediol is an excellent moisturizer with antibacterial effects. It exhibits synergistic effects with traditional preservatives and helps reduce the amount of traditional preservatives used in formulations. In sunscreen products, it further enhances the product's water resistance and solubility for certain ingredients. 1,2-Pentanediol contributes to formulation stability and reduces the stickiness caused by added polymers.

Product Characteristics
1. Broad-spectrum antibacterial activity, effectively inhibiting Gram-negative bacteria, Gram-positive bacteria, yeasts, and molds.
2. As a emollient, pentylene glycol has excellent skin moisturizing properties, reducing moisture loss from the skin, leaving it soft, smooth, and enhancing the moisturizing function of skincare products.
3. Pentylene glycol is a multifunctional ingredient with excellent antimicrobial capabilities. It is not registered as a preservative and is permitted for use in cosmetics, fully supporting the "zero preservative" concept.
4. Gentle and non-irritating, reducing irritation and allergies caused by preservatives. It is also a high-purity liquid emollient with broad-spectrum antibacterial activity, classified as an emollient, very gentle, conforming to international regulatory trends, and widely used globally.
5. Excellent compatibility; can be added to the oil phase to improve the water resistance of sunscreen formulations; soluble in water and readily soluble in polyols such as ethylene glycol, propylene glycol, and glycerin.
Applications in Skincare Products
1,2-Pentanediol is a small-molecule humectant, a synthetic moisturizer used as a solvent and preservative in cosmetics and beauty products. It has water-locking and antibacterial functions and can improve the water resistance of sunscreens. However, this ingredient can cause slight eye irritation but is non-irritating to the skin.
Pentanediol can be used in emulsification systems, water-based systems, anhydrous formulations, and surfactant-based detergents, especially suitable for baby products and additive-free products. Examples include creams, lotions, shower gels, wet wipes, toners, and shampoos. Additionally, pentanediol can effectively prevent the growth of fungi in wet wipes.
