摘要:
The present invention provides a method for manufacturing a hydrogel sheet product. The method for manufacturing a hydrogel sheet product includes: a step of coating a hydrogel forming composite containing a high molecular weight hydrophilic solution including polyacrylic acid or salt thereof, a cross-linking agent, a gelation speed modifier, and water, on a support body; a step of ripening a hydrogel layer for the polyacrylic acid or the salt thereof to be cross-linked by the cross-linking agent; a forming step of cutting the ripened hydrogel sheet in a desired shape; a step of inserting the formed hydrogel sheet into a package bag; a step of impregnating an impregnated liquid into the hydrogel layer by injecting the impregnated liquid formed of water of a hydrophilic solution into the package bag; and a sealing the package bag. According to the present invention, a hydrogel sheet product sufficiently contains active ingredients such as water, polyhydric alcohol, and a moisturizer in hydrogel and when in contact with the skin, these active ingredients are transferred effectively. The hydrogel sheet product has high product satisfaction since users feel relief when the cosmetic ingredients remain on the skin. According to the present invention, the hydrogel sheet product is convenient to use and does not waste cosmetic ingredients since the active ingredients such as water, polyhydric alcohol, and the moisturizer contained in the hydrogel stay in contact with the hydrogel sheet during storage and distribution. The hydrogel sheet product has excellent skin adhesiveness.폴리아크릴산 또는 그의 염을 포함하는 친수성 고분자, 가교제, 겔화속도 조절제 및 물을 포함하는 하이드로겔 형성 조성물을 지지체에 코팅하는 단계; 상기 하이드로겔층에서 폴리아크릴산 또는 그의 염이 가교제에 의하여 가교되도록 숙성하는 단계; 상기 숙성된 하이드로겔 시트를 원하는 형상으로 절단하는 성형단계; 상기 성형된 하이드로겔 시트를 포장봉투에 삽입하는 단계; 상기 포장봉투에 물 또는 친수성 용액으로 되는 함침액을 투입하여 상기 하이드로겔층에 상기 함침액이 함침되도록 하는 단계; 및 상기 포장봉투를 밀봉하는 단계를 포함하는 하이드로겔 시트 제품의 제조방법이 개시된다. 본 발명에 따른 하이드로겔 시트 제품은 하이드로겔 자체에 물, 다가 알콜 및 보습제 등과 피부유효성분을 충분히 함유하면서 피부에 부착하였을 때 그러한
