Description

1,2-Nonanediol is a versatile, high-purity diol compound with the CAS number 42789-13-9, valued for its dual functionality as a humectant and a mild, broad-spectrum preservative. This makes it a critical ingredient for formulators seeking effective, multifunctional, and consumer-friendly solutions. It is primarily needed by manufacturers in the personal care, cosmetics, and pharmaceutical industries for its ability to enhance product stability, safety, and sensory profile.

Application

• Cosmetic & Personal Care Preservative: Acts as a gentle yet effective antimicrobial agent in creams, lotions, sunscreens, and makeup, often used in "preservative-free" or low-preservative formulations.
• Skin Care Humectant & Moisturizer: Provides excellent hydrating properties by attracting and retaining moisture in the skin, improving the texture and efficacy of serums and moisturizers.
• Pharmaceutical Formulations: Used as an excipient in topical preparations for its solubilizing, stabilizing, and antimicrobial-enhancing properties.
• Fragrance & Perfumery: Serves as a solvent and fixative for fragrances, helping to stabilize scent profiles in fine perfumes and functional products.
• Industrial Applications: Functions as an intermediate in organic synthesis and as a component in specialty coatings, inks, and lubricants where specific diol properties are required.
