The present invention relates to a high-performance eco-friendly moisture absorbent that has a fast moisture absorption rate and strong moisture absorption power, but does not leak a moisture absorbing liquid to the outside, so as to prevent corrosion or damage to machinery that may be exposed to high humidity for a long period of time and condensation on windows or lenses in optical devices, lamps, automobile headlights, and the like. The present invention includes a main moisture absorbent, a moisture absorbing liquid condensing agent, and a moisture absorbing aid in waterproof breathable paper, wherein calcium chloride or magnesium chloride having high deliquescent properties as the main moisture absorbent, a polymer coagulant that prevents leakage by condensing the contents in a gel state as the moisture absorbing liquid condensing agent, and natural minerals with functions of supplementing moisture absorption and securing swelling space as the moisture absorbing aid are mixed. 본 발명은 장기간 고습에 노출될 수 있는 기계류의 부식이나 손상 및 광학기기나 램프, 자동차 헤드라이트 등에서 창이나 렌즈에 생기는 결로를 방지할 수 있도록 흡습 속도가 빠르고 흡습력은 강하면서도 흡습액이 외부로 유출되지 않는 고성능 친환경 흡습제에 관한 것으로, 투습방수지 내부에 주흡습제, 흡습액응결제 및 흡습보조제를 포함하며, 주흡습제로써 높은 조해성을 갖는 염화칼슘 또는 염화마그네슘과, 흡습액응결제로써 내용액을 겔상태로 응결시켜 유출을 방지하는 고분자응집제와, 흡습보조제로써 흡습 능력 보완 및 팽윤 공간 확보의 기능을 갖는 천연광물을 혼합한 것이다.
