Butene, homopolymer (CAS 9003-29-6) — Citrus N/A Note Fragrance Ingredient
Butene, homopolymer
CAS 9003-29-6
What Is Butene, homopolymer?
Butene homopolymer is a synthetic polymer used as a base material in various industrial applications, including adhesives and coatings. It’s not commonly encountered in consumer products but may appear in specialized formulations. This ingredient serves as a structural component rather than a fragrance, valued for its physical properties in material science applications.
Safety Profile
PROFESSIONAL USEWhat Does Butene, homopolymer Smell Like?
Butene homopolymer is typically odorless in its pure form, serving functional rather than olfactory purposes. As a synthetic polymer, it lacks the volatile organic compounds that produce detectable fragrance characteristics. Its molecular structure doesn’t facilitate the release of aromatic compounds that would interact with olfactory receptors.

Chemistry, Properties & Perfumer Guide
The Chemistry
Butene homopolymer is a synthetic polymer formed through the polymerization of butene monomers. This hydrocarbon polymer is created via catalytic polymerization processes, typically using Ziegler-Natta or metallocene catalysts. The material properties vary based on the degree of polymerization and branching in the molecular structure. As a polyolefin, it shares chemical similarities with polyethylene and polypropylene.
