ABSTRACT:
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.
