Is there anything wrong with keeping oil, salt, and vinegar together

Question

I am curious if there is anything wrong with keeping oil, salt, and vinegar together.

A month ago I made a small mixture of those and brought it to my work, to use it for salad. Do some of them do some unwanted chemical interactions? They are rapeseed oil, sea salt, and ordinary vinegar. I didn't refrigerate them. I suppose I am not the only one curious about this.

Answer

No, as you can keep them separately for a long time, The point is, no chemical reaction accur because they don't have right particles for a chemical reaction, it's just a mixture and no new substances is made. I think they are still healthy like that.

Also, accroding to a very nice article about keeping oil and vinager ( http://oilandvinegar.cruets.com/keeping-oil-and-vinegar ), despite they can be stored for a long period of time , depends on the place and container you keep them in:

Olive oil and vinegar have four deadly enemies. They are:
1. Age
2. Heat
3. Light
4. Air

One of the above or a combination of any of these four can damage olive oil and vinegar beyond measure.

So in a dark and cool place and not a plastic container,they can be stored for 15 months.
