Title (EN) COOLING AGENT FOR COLD PACKS AND FOOD AND BEVERAGE CONTAINERS
(FR) AGENT RÉFRIGÉRANTS POUR POCHES FROIDES ET RÉCIPIENTS POUR ALIMENTS ET BOISSONS
Abstract:
(EN) Safe, stable, non-toxic and recyclable cooling agent compositions comprising solid particulate compounds undergo an endothermic process when mixed with water such that the resulting mixture is useful for cooling surfaces, liquids and solids. The mixtures include ammonium nitrate in an amount of at least 45 wt% of the mixture. Total nitrogen-containing salts exclusive of phosphates are present in an amount less than 68% by weight of the composition. A phosphate salt is also present in an amount as needed to stabilize the composition against detonation. A balance of additional salts is formulated to provide the mixture with a cooling capacity of at least 240 kJ/kg of the mixture.
(FR) L'invention concerne des compositions d'agent réfrigérants sûres, stables, non toxiques et recyclables comprenant des composés particulaires solides subissant un processus endothermique lorsqu'ils sont mélangés à de l'eau de telle sorte que le mélange résultant est utile pour le refroidissement de surfaces, de liquides et de matières solides. Les mélanges comprennent du nitrate d'ammonium en une quantité d'au moins 45 % en poids du mélange. Les sels contenant de l'azote totaux à l'exclusion des phosphates sont présents en une quantité inférieure à 68 % en poids de la composition. Un sel phosphate est également présent en une quantité nécessaire pour stabiliser la composition contre l'explosion. Un complément de sels supplémentaires est formulé pour donner au mélange avec une capacité de refroidissement d'au moins 240 kJ/kg du mélange.
