Description

1,2-Octanediol CAS NO 1117-86-8 is a versatile aliphatic diol that serves as a multifunctional ingredient in advanced formulations. Its unique combination of a short hydrophilic diol head and a longer hydrophobic carbon chain provides excellent humectant, solvent, and antimicrobial properties. This compound is essential for manufacturers in the personal care, pharmaceutical, and industrial sectors seeking effective, mild, and multifunctional performance additives.

Application

• Cosmetics & Personal Care: Used as a humectant, viscosity modifier, and solvent in creams, lotions, sunscreens, and deodorants. Its mild antimicrobial properties help reduce preservative loads.
• Pharmaceuticals: Functions as a co-solvent and penetration enhancer in topical formulations such as gels, ointments, and transdermal patches.
• Industrial Applications: Acts as an intermediate in the synthesis of polymers, plasticizers, and specialty surfactants.
• Cleaning & Disinfection: Incorporated into hard-surface cleaners and disinfectant wipes for its solvent and antimicrobial efficacy.
• Coatings & Inks: Serves as a coalescing agent and flow improver in water-based coatings and printing inks.
