Background:
Allergic contact dermatitis from nickel is very common in the United States. A barrier coating to be used on personal items such as snaps or watches would be of great use in preventing the consequences of nickel allergy.
Objective:
To evaluate various barrier coatings and their ability to yield a negative dimethylglyoxime (DMG) test result.
Methods:
Four different barrier coatings were assessed prior to soaking in saline, after soaking in saline for 2 days, and after soaking in saline for 7 days.
Results:
Depending on the number of coatings and the time soaked in saline, the different barriers showed different efficacies in yielding a negative DMG test result.
Conclusions:
Nickel Guard and Beauty Secrets Hardener were most effective in yielding a negative DMG test result. Beauty Secrets Hardener was the more cost-effective choice.

Precipitation Gravimetry
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...
