Ethyl vinyl acetate copolymer (CAS 24937-78-8) — Citrus N/A Note Fragrance Ingredient
Ethyl vinyl acetate copolymer
CAS 24937-78-8
What Is Ethyl vinyl acetate copolymer?
Ethyl vinyl acetate copolymer is a synthetic polymer used in adhesives, coatings, and flexible packaging. It provides durability and flexibility to products like hot melt adhesives and plastic wraps. While not typically used in fragrances, it plays a crucial role in encapsulation technologies for controlled scent release in consumer products.
Safety Profile
GENERALLY SAFEWhat Does Ethyl vinyl acetate copolymer Smell Like?
Ethyl vinyl acetate copolymer itself is odorless, serving as a functional material rather than a fragrance ingredient. Its value lies in its physical properties—flexibility, adhesion, and compatibility with other materials—making it ideal for encapsulating fragrances or as a binder in scented products.
