Abstract
Abstract Compositions which releases fragrance without burning and which comprise a petroleum wax base, 2 to 7 weight percent butyl rubber, 1 to 5 weight percent ethylene vinyl acetate copolymer and 9 to 15 weight percent fragrance are described. The compositions can be molded or otherwise formed into durable fragrance-emitting articles. The preferred compositions comprise 73 to 88 weight percent paraffin wax, 0 to 10 weight percent microcrystalline wax, 0 to 10 weight percent petrolatum, 1 to 5 weight percent ethylene vinyl acetate copolymer, 2 to 7 weight percent butyl rubber and 9 to 15 weight percent fragrance. Such compositions may be flush molded into hollow shells which may be filled, preferably with a foamed wax.
