    Abstract: The present invention relates to a mask pack using temperature-responsive sol-gel transfer hydrogel and, more specifically, to a temperature-responsive mask pack manufactured by mixing a hydrophilic polymer or an amphipathic polymer including two or more phosphate groups and a multivalence cation corresponding to a negative charge of the phosphate group and aging, and including a sol-gel transfer hydrogel transferred from the sol state to the gel state at the temperature range of 10-50°C and skin active ingredients. The mask pack using temperature-responsive sol-gel transfer hydrogel according to the present invention uses the temperature-responsive hydrogel existing in the sol state at low temperatures and existing in the state transformation into the sol state at body temperatures, so that a large amount of skin active ingredients is rapidly spread on the skin at the beginning, and the hydrogel gelates by the skin temperature afterward to form a film. Therefore, the moisture retention maintains to minimize evaporation of the skin active ingredients, thereby improving absorption and usability of the skin active ingredients.
