Abstract
The phosphorescent toy gel composition is produced by suspending phosphorescent particles in an aqueous solution, thickened with guar gum and crosslinked by a borate compound. The method for manufacturing the phosphorescent gel composition comprises, in one aspect, the steps of providing a water-based solution with a borate ion-containing compound dissolved in the water, providing guar gum and phosphorescent particles suspended and dispersed in propylene glycol, and mixing the water-based solution and the propylene glycol dispersion in a proportion to provide a phosphorescent gel composition.
