The abstract of an interesting new study set to appear in Dermatitis Journal has just been published looking at US consumer adhesives — ie glues. Read it here.
The aim was to examine popular glues for isothiazolinone content, not only the big 4 of MI, MCI, BIT and OIT, but also the lesser-known butyl-BIT — although that happened to be the only one not found in a sample of almost 40 adhesives analysed using high-tech techniques.
Here is a summary of the main findings:
1/ 50% of the adhesives contained at least one isothiazolinone preservative
2/ 40% contained two isothiazolinones
3/ Most isothiazolinone found was MI and / or MCI
4/ Six adhesives contained BIT, and only one contained OIT
and, perhaps the most interesting of all:
5/ All-purpose glues had a lower concentration of MI and MCI, whereas craft glues were associated with higher concentrations of MI and MCI.
6/ Fabric adhesives were associated with a higher risk of containing BIT.
Finding safe glues and adhesives
This is not easy, and I admit I’ve not looked into this subject in depth. I will start to contact brands directly this week.
Blogger Jill Sandager, who says that most PVA glues contain isothiazolinones, touched upon the issue of glues in this post about arts supplies, which may offer some leads. For example, a commenter to that thread said that in the US these Colorations Glue Stick products are apparently safe.
If you know of any other confirmed safe options, of all types of glues, do leave a comment. Same goes if you’d like me to investigate any particular brands on your behalf. Will report back in the coming weeks ….
