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 14 -C 22 straight or branch chain alkyl alcohol and from about 5 to 20 percent by weight of a fragrance material.
Claim 3
Dependent Claim
31 words
The molded article of claim 1 wherein the polyamide has a softening point of less than about 200° C and a viscosity of less than about 90 poises at 225° C.
Claim 4
Dependent Claim
18 words
The molded article of claim 2 wherein the polyamide is formed from polymerized linoleic acid and a polyamine.
Claim 5
Dependent Claim
21 words

Claim 6
Dependent Claim
11 words
The molded article of claim 4 wherein the alcohol is 2-octyldodecanol.
Claim 7
Dependent Claim
19 words
The article of claim 2 wherein the composition further contains up to 15 percent by weight of mineral oil.
Claim 8
Dependent Claim
79 words
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 14 -C 22 alkyl alcohol and from about 5 to 20 percent by weight of a fragrance material.
Claim 9
Dependent Claim
79 words
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 14 -C 22 alkyl alcohol and from about 5 to 20 percent by weight of a fragrance material.
