Storing castor oil

Hello, friends,

The castor oil group is a bit quiet. So, let me repost my questions here:

What's the best way to store castor oil? I usually pour some into an easier-to-handle small lotion bottle, but leave all the oil at room temp.

1) Should I refrigerate my "mother" bottle?

2) How long a shelf life does an open castor oil have?

Thanks very much!
