다시 뛰는 공정도시 서울!

초록

Fifty samples of children’s toothpaste marketed in Seoul were tested for tar colors
using the modified color additives method of the Korean Food Standards Codex. 11
samples were labeled as containing tar colors？6 of them claimed to contain 1 tar
color, 4 of them claimed to contain 2 tar colors, and 1 of them claimed to contain 3
tar colors. Blue No. 1 was detected in 7 samples, Yellow No. 203 in 4 samples, and
Red No. 227 in 3 samples, all at concentrations less than the limit of 0.1%. The
banned tar color, Red No. 2 was not detected in any of the samples. Some
inconsistencies between labeling and analytical results were noted: Blue No. 1 was not
detected in the 3-tar sample which stated Red No. 227, Yellow No. 203 and Blue No.
1 on the label; and one sample listed Green No. 3 but instead contained Blue No. 1.
Calculation of risk is based here on the assumption that children use 1 g of toothpaste
three times a day to brush their teeth, and swallow all of the toothpaste. Under these
circumstances, ingestion of tar colors would be much less than their ADI. However ADI
data does not exist for all tar colors that might be used, so further studies are needed
to assess the safety of other tar colors that may be used in children’s toothpaste.
