The invention is a composition especially for ear plugs comprised of a starch based ester of a dicarboxylic acid, lecithin, wax, trace amounts of vitamins A, C, and E and a biocidal amount of grapefruit seed extract. The ear plug composition is especially useful as it retains its elasticity after prolonged use and after being subjected to temperature extremes. The composition is safe, and also kills germs due to biocidal action of grapefruit seed extract among other ingredients. |
