Hexyl methacrylate (CAS 0142-09-06) — Citrus N/A Note Fragrance Ingredient
Hexyl methacrylate
CAS 0142-09-06
What Is Hexyl methacrylate?
Hexyl methacrylate is a synthetic compound used in industrial applications and some specialty adhesives. While not commonly found in consumer products, it’s important in manufacturing certain plastics and coatings. This ingredient matters because it demonstrates how chemical modifications can create materials with specific properties, though its use requires careful handling due to potential health considerations.
Safety Profile
PROFESSIONAL USEWhat Does Hexyl methacrylate Smell Like?
Hexyl methacrylate has a sharp, acrid odor characteristic of acrylic monomers. The scent profile is industrial with plastic-like top notes that carry a faint fruity undertone. As it evaporates, the odor becomes more pungent and chemically aggressive, leaving a lingering synthetic impression. The dry-down reveals its true nature as a volatile monomer with no redeeming olfactory qualities for perfumery.

Chemistry, Properties & Perfumer Guide
The Chemistry
Hexyl methacrylate is an ester of methacrylic acid and hexanol, belonging to the acrylate family. This monomer is primarily used in polymerization reactions to create acrylic resins and specialty plastics. The hexyl chain provides flexibility to resulting polymers while maintaining the reactive double bond characteristic of methacrylates. Industrial synthesis typically involves esterification of methacrylic acid with hexanol under acidic conditions.
