Estimating the term…
A resinous composition for fragrant substances is provided which comprises an ethylene-vinyl acetate copolymer containing from about 5% to about 35% of vinyl acetate monomer, by weight, and a diffusing agent selected from the group consisting of benzyl benzoate, benzyl salicylate, and di-(lower alkyl)phthalates, and mixtures thereof. The diffusing agent is absorbed in the copolymer. When fragrant substances are enclosed in a container made from the resinous composition of the present invention or the composition of the present invention is impregnated with such fragrant substances, a well-balanced, mild fragrance, inherent to the fragrant substance employed, is uniformly released over a long period of time.
A fragrant article, comprising an ethylene-vinyl acetate copolymer impregnated with a diffusing agent and a fragrant substance, said copolymer comprising from about 15% to about 30% of vinyl acetate monomer, by weight, and about 85% to about 70% of ethylene monomer, by weight, said diffusing agent being selected from the group consisting of benzyl benzoate, benzyl salicylate, and mixtures thereof, and being absorbed in the copolymer in an amount of from about 1% to about 10% by weight of the copolymer.
A fragrant article, comprising an hermetically sealed container enclosing a fragrant substance, said container comprising an ethylene-vinyl acetate copolymer impregnated with a diffusing agent, said copolymer comprising from about 15% to about 30% of vinyl acetate monomer, by weight, and about 85% to about 70% of ethylene monomer, by weight, said diffusing agent being selected from the group consisting of benzyl benzoate, benzyl salicylate, and mixtures thereof.
A fragrant article, consisting essentially of an ethylene-vinyl acetate copolymer impregnated with a diffusing agent and a fragrant substance, said copolymer consisting essentially of from about 15% to about 30% of vinyl acetate monomer, by weight, and about 85% to about 70% of ethylene monomer, by weight, said diffusing agent consisting essentially of from about 1% to about 10%, by weight of the copolymer, of a compound selected from the group consisting of benzyl benzoate, benzyl salicylate, and mixtures thereof.
