What we know
- From Mentality’s Facebook page:
- From people who own the affected polishes:
- Some people were reporting stinging, itching and redness upon application.
Faulty Arminex Base Theories
1. Citric acid
Problematic base (spelling corrected *grinds teeth*):
Verdict: Highly unlikely. Don’t chuck out all your citric acid-containing polishes!
2. Contamination of Arminex base in general
For all faulty Arminex base theories:
- Arminex have been around a lot longer and haven’t screwed up before (as far as we know).
Verdict: Unlikely, but possible
Faulty Polish Theories
1. Fungal contamination
- Fungi don’t survive well in nail polish since it’s full of solvent.
Verdict: Highly unlikely. The fungal infections probably occurred after detachment of the nail.
2. Unstable pigment
- Formaldehyde is known to cause onycholysis.
3. Destabilised polish due to degassing etc.
4. Mystery homemade base
5. Heavy metal contamination (added 27/8)
Heavy metal contamination is a theory I’ve recently seen popping up in some discussions.
- Heavy metals are sometimes used in colouring agents, and is often in industrial waste.
- BUT… they don’t sting or cause any other short term effects.
Verdict: Highly unlikely. They could be in there, but they’re not causing the problems we’re seeing.
6. Methacrylate contamination (expanded 27/8)
Here’s the latest proposed suspect from Mentality: methacrylate contamination of the Arminex base.
- 2-Hydroxylethyl methacrylate (HEMA) is another common allergen found in gels.
- When cured properly under a UV lamp, there should be no irritation.
a. Arminex contaminated the polish base accidentally during manufacture: Unlikely
b. Arminex sent them the wrong base altogether: Unlikely but possible
- It’s possible that they just accidentally used premade gel base instead of normal base.
d. Mentality contaminated the polish base accidentally with raw gel materials: Possible
- Mentality have been experimenting with making gel base from raw gel materials.
Final Word of Caution
- Arminex claim that the problems with Mentality came up before Mentality bought their base, Mentality claim otherwise.
- Arminex states that no other companies who bought that base have reported problems.
- Mentality have sent samples of Arminex’s Matte Creme Base (used in the Textures collection) and some New Transparent Glitter Base (pulled when bloggers uncovered sensitivities.
- Were the Textures actually one of the collections affected?
