A composition of a moisture absorbent for a vehicle lamp and moisture absorbing product for a vehicle lamp including the same according to the present invention may have a high moisture absorption rate and low release rate by adjusting the composition ratio and specifications of magnesium chloride, magnesium oxide, and carboxymethyl cellulose to a specific range, and minimize damage to packaging containers and products subject to dehumidification by suppressing volume change due to moisture absorption, the expansion rate and hardness to be low after the maximum moisture absorption.

    본 발명에 따른 자동차 램프용 흡습제 조성물 및 이를 포함하는 자동차 램프용 흡습제품은 염화마그네슘, 산화마그네슘 및 카르복시메틸셀룰로스의 조성비 및 제원을 특정 범위로 조절함으로써 높은 흡습율 및 낮은 방출율을 가지며, 흡습에 따른 부피변화를 억제하여 최대 흡습 후 팽창율 및 경도가 낮도록 유지함으로써 포장용기 및 제습대상제품의 파손을 최소화할 수 있다.
