Sustained release composition comprises (wt.%) insecticide (a) (1 - 30); insect repellant agent (b) (0.1 - 20); and/or agent for animal care (c) (0.1 - 20), thermoplastic polymer (d) (50 - 95), liquid (e) (1-22) which is incompatible with (d), and optionally at least one additive (f) usable in polymer processing. Provided that the total amount of (a), (b) and/or (c) does not exceed 30 wt.%. A sustained release composition comprises (wt.%): an insecticide (a) (1 - 30); an insect repellant agent (b) (0.1 - 20); and/or an agent for animal care (c) (0.1 - 20), a thermoplastic polymer (d) (50 - 95), a liquid (e) (1-22) which is incompatible with (d), and optionally at least one additive(s) (f) usable in polymer processing. Provided that the total amount of (a), (b) and/or (c) does not exceed 30 wt.%. The solubility of (a), (b) and/or (c) in (e) is at least 10 times higher than the solubility of (d) in (e). (a), (b) and/or (c) is practically insoluble in (d). (d) and (e) are chemically inert towards (a), (b) and/or (c). An independent claim is also included for a shaped article made from the composition. ACTIVITY : Insecticide; insect repellant. No details of tests are given. MECHANISM OF ACTION : None given in the source material. |
