Patent ID: 7201915

Claim:
A substantially hydrocarbon-free functional substance-providing stick article having consistently-maintained functional composition and dimensional integrity comprising a stiff, monophasic, thermally-reversible composition comprising: (a) a structural support polymer selected from the group consisting of at least one ester-terminated polyamide and at least one tertiary amide-terminated polyamide; (b) a system-compatible functional composition selected from the group consisting of a perfume composition, an insect repellant composition, an animal repellant composition, an anti-microbial composition, an insect attractant composition and an air freshener composition; and (c) an operativeness additive wherein the operativeness additive is a mixture of octyl stearate, octyl palmitate and dioctyl adipate; with the provisos that the weight ratio range of structural support polymer: system-compatible functional composition is from about 90:10 to about 55:45 and the weight percent of operativeness additive is from about 0.2% to about 10% by weight of the functional substance-providing stick article.
