Description

7-Methyl-7-Heptadecanol is a high-purity, branched-chain fatty alcohol with a unique molecular structure. This compound serves as a valuable intermediate and functional ingredient, prized for its ability to modify physical properties and impart specific characteristics in advanced formulations. It is primarily sought by manufacturers in the fragrance, cosmetic, and specialty chemical industries for applications requiring precise molecular architecture and consistent performance.

Application

• Fragrance & Flavor Intermediates: Acts as a key building block for synthesizing musky and woody aroma chemicals, contributing to long-lasting scent profiles in perfumes and personal care products.
• Cosmetic & Personal Care Ingredients: Used as an emollient, texture enhancer, or carrier in high-end skincare, lotions, and creams due to its favorable skin feel and stability.
• Lubricant & Grease Additives: Serves as a synthetic base fluid or performance additive to improve viscosity index, low-temperature properties, and oxidation stability in specialty lubricants.
• Polymer & Plasticizer Modification: Employed as a co-monomer or modifier to alter the flexibility, crystallinity, and processing characteristics of polymers and plasticizers.
• Surfactant & Detergent Synthesis: Functions as a hydrophobic tail in the production of non-ionic surfactants for industrial and institutional cleaning formulations.
• Chemical Research & Development: Utilized as a standard or reagent in organic synthesis and material science research for developing novel compounds.
