Heavy metals have been analyzed on the non-woven from the 24 kinds of wet wipes and 8 kinds of mask packs. The following materials used in the non-woven according to each product are: rayon+polyester for the 12 wet wipe products, rayon+PET for the 5 wet wipe products, and rayon, cotton, rayon+polyester+cotton, pulp+polypropylene for the rest of the wet wipe products. No further information on the materials was found on the 3 wet wipes and 8 mask packs. However, polyester may be applied for the non-woven in wet wipes, because PET is part of the polyester group. The heavy metals analysis in the 24 kinds of wet wipes and 8 kinds of mask packs revealed the following: arsenic was found from 47.14±1.13 to 71.75±1.64 ㎍/L on the 3 products, the amount of nickel in the 2 products were 261.26±5.14 and 1,242.63±43.71 ㎍ /L, 53.69±1.45 and 103.52±2.02 ㎍/L on the 2 mask packs. It was also revealed that lead was detected from 7.23±0.32 to 55.67±1.46 ㎍/L on the 6 wet wipes, antimony was ranged from 187.86±5.24 to 19,558.35±3,537.30 ㎍/L on the 12 wet wipes, and 5.25±0.25 and 8,936±55.22 ㎍/L on the 2 mask packs. No cadmium, mercury, or thallium were detected from all the products. A high concentration of antimony might come from antimony trioxide, which was used as a catalyst when manufacturing the polyester. Therefore, it is strongly recommended that a non-woven used for cosmetic purposes should not use heavy metals as a catalyst when manufacturing, and it’s important to clarify which materials are used in non-woven.
