Claims16
A shaped, self-supporting transparent article capable of emitting a fragrance over a sustained period comprising a substantially homogeneous mixture of from about 40 to 60% by weight of a polyamide resin formed from a polymerized fatty carboxylic acid and a polyamine, from about 35 to 55 percent by weight of a C.sub.14 -C.sub.22 straight or branch chain alkyl alcohol and from about 5 to 20 percent by weight of a fragrance material.
A shaped self-supporting molded article capable of emitting a fragrance over a sustained period comprising an inert non-fragrance emitting core and, adhered thereto, a substantially homogeneous mixture comprising from about 40 to 60 percent by weight of a polyamide resin formed from a polymerized fatty carboxylic acid and a polyamine, from about 35 to 55 percent by weight of a C.sub.14 -C.sub.22 alkyl alcohol and from about 5 to 20 percent by weight of a fragrance material.
A process of forming a self-supporting, shaped transparent article capable of emitting a fragrance over a sustained period comprising mixing at a temperature of from about 150.degree. C. to 200.degree. C. for a time to achieve a substantially complete homogeneous mixture from about 40 to 60 percent by weight of a polyamide resin formed from polymerized fatty carboxylic acid and a polyamine, from about 35 to 55 percent C.sub.14 -C.sub.22 alkyl alcohol and from about 5 to 20 percent volatile fragrance material, casting the resultant molten mixture in a mold of desired configuration and cooling the molded article.
A process of forming a self-supporting molded article capable of sustained fragrance emmission comprising initially forming a shaped article from a non-fragrance composition capable of bonding with a polyamide coating, adhereing about the shaped article a molten composition comprising a substantially homogeneous mixture of from about 40 to 60 percent by weight of a polyamide resin formed from a polymerized fatty carboxylic acid and a polyamine, from about 35 to 55 percent by weight of a C.sub.14 -C.sub.22 alkyl alcohol, and from about 5 to 20 percent by weight of a fragrance material, and cooling said composition.
