Oxirane, methyl-, polymer with oxirane, monobutyl ether (CAS 9038-95-3) — Citrus Non-aromatic Note Fragrance Ingredient
Oxirane, methyl-, polymer with oxirane, monobutyl ether
CAS 9038-95-3
What Is Oxirane, methyl-, polymer with oxirane, monobutyl ether?
This synthetic polymer is used as a solvent and carrier in industrial fragrance applications. Consumers may encounter it in cleaning products or functional fragrances where controlled release is needed. While not directly contributing scent, it plays a technical role in fragrance performance by modifying viscosity and evaporation rates.
Safety Profile
USE WITH AWARENESSWhat Does Oxirane, methyl-, polymer with oxirane, monobutyl ether Smell Like?
This technical polymer is essentially odorless, functioning primarily as a solvent carrier rather than an aromatic contributor. Its molecular structure allows it to modulate the release of other fragrance components without imparting its own olfactory character.
Chemistry, Properties & Perfumer Guide
The Chemistry
A synthetic polyether formed through the polymerization of propylene oxide and ethylene oxide with butanol. The molecular weight distribution varies by manufacturing process. The butyl ether termination provides lipophilic character while the polyether backbone offers water compatibility.
