HYDROGEL COMPOSITION FOR MASKING PACK CONTAINING WATER-SOLUBLE POLYURETHANE

摘要

The present invention relates to a hydrogel composition and, more specifically, to a hydrogel composition having improved elasticity and air permeability by including water-soluble polyurethane. Based on the total weight of the hydrogel composition, the hydrogel composition comprises 0.01 to 5.0 wt% of water-soluble polyurethane; 0.4 to 5.0 wt% of a natural polymer gelating agent; 1.0 to 60.0 wt% of a functional cosmetic component for imparting a skin beautifying function; 0.1 to 1.0 wt% of an electrolyte; 10.0 to 30.0 wt% of polyalcohol as a plasticizer; a preserving agent; and a solvent including other water. The hydrogel composition of the present invention is a cosmetic mask distributed after being pre-produced in a face shape or patch shape. The hydrogel composition has improved elasticity so as to be excellently adhered on the skin without an additional adhesive component, and the shape thereof can be maintained for a long time. Air permeability is improved, so that a useful component for skin can be easily transferred to the skin without concern over skin irritation.
