Insulin in freezer for a reason

[Blue_Star]

I live in Karachi, Pakistan and recently we had a whole day( from 10am upto 9 pm of no electricity)due to power station problems. It was getting pretty hot so I had to store my insulin in the freezer section just to keep it cool. In the evening I had to go out (important reason) for about an hour. I was later told by neighbours that electricity did come around for an hour b4 going off again. My question is does insulin freeze in an hour if left in the freezer ?? I didn't leave the pens directly in the freezer but in a cool bag. Is it ok to use that insulin ?? I'm so worried abt this

Cool bags are good insulators and work equally well at keeping both heat and cold out, so I would guess that your insulin is ok. I think it turns cloudy if it's been too cold (I may be wrong though).
