shelf life monomers,polymers and primers???

[Mieke]

Hi,

I was just wondering if primer, monomer and polymers go bad after a while even in an unopened state? How long does it take...?
If so how can you tell? is it the color etc...

I'm not 100% sure on this, but I feel I've read or seen somewhere that it's about 2 years.

I have recently just renewed my CND Nailfresh & CND Acid Free Primer & when the primer came through, it was a different colour than the one I had had sitting on my nail station for nigh on 2 years!

Don't know the answer to powders though....if they are unopened I cannot see why it would be a problem, assuming they had been stored correctly (which was obviously not the case for my primer, as I'm sure someone will tell me/us!)

Thx allready for the info. I am moste curious about the polymers aswell. The problem is i got some ezflow products from a girl that quited before i started and they haven,t been used before. The thing is...i just said thx but didn,t asked her how long she got them. so i thought i want to ask if there are any visible signs of the products being old. I would just use them to try it out on myself but if it,s old i am so not going to do that :lol:

Yellowing is the most obvious sign of an ageing product. Polymers can yellow so the pink would look peachy and the white would look 'yellowy', even before you used them.

I allready thought they looked suspicious in color...

I'll throw it all out then, not worth the trouble thinking about it actually

At least i learned something new...now i know how to spot something getting old. Not that i think i will ever come across it myself since I have to buy new products regularly.

Thx for all the help :hug:
