Abstract

La présente invention concerne un emballage thermochromique pour des compositions dépilatoires qui est réalisé dans un matériau plastique, caractérisé en ce que l'emballage comprend, dans sa composition, au moins un matériau thermochromique qui contient deux ou plus de deux compositions thermochromiques réversibles, la première suivant une concentration comprise entre 0,1 et 8% et la seconde suivant une concentration comprise entre 0,05% et 8% en poids du poids total du matériau thermochromique, les deux étant sensibles à la chaleur à une température supérieure à 40°C mais différentes l'une de l'autre, de telle sorte que la première est sensible à la chaleur sur un intervalle de température inférieur à la seconde. En raison des propriétés thermochromiques de l'emballage de l'invention, ledit emballage présente la capacité de changer de couleur en fonction de la température qui est appliquée, après son traitement, et informe l'utilisateur du moment approprié à son utilisation et le prévient de ne pas l'utiliser lorsque le moment n'est pas approprié.
