Problems solved by technology

In addition, hydrogels contain a lot of water and have low air permeability, causing the problem of skin softening when applied for a long time
[0004] Ordinary polyurethane is flexible and has excellent air permeability, but it is insoluble in water. As a cosmetic, there are restrictions in containing water-soluble active ingredients that account for a large part of the active ingredients on the skin; gels composed only of water-soluble polyurethane materials themselves , can contain water-soluble active ingredients, but the skin adhesion is reduced. Compared with the gel composed of natural polymer gels, there are problems that are not compatible with the skin and are not environmentally friendly.

Abstract

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.

Description

technical field [0001] The present invention relates to a hydrogel composition, and more specifically, to a hydrogel composition for a facial mask containing water-soluble polyurethane that improves the elastic properties of the gel and has air permeability. Background technique [0002] As a substance with high water content that contains a large amount of water, such as medicine, pharmaceuticals, prostheses and contact lenses, its application fields are showing a trend of diversification. Recently, it is used not only as a wound dressing and a drug delivery medium, but also in the field of cosmetics to deliver various effects such as moisturizing, nutrition supply, wrinkle improvement, and whitening to the skin. [0003] Generally speaking, hydrogels containing natural polymer gels are produced through various processes such as liquid-assisted forming, processing, and packaging. They are only realized with natural polymer gels, and their elastic properties and resistance t...
