Is rice water good for your skin and how long after its made is it safe for your skin?

I recently made a rice water toner. I read it was very beneficial for the health of your skin. I used it about twice and it hasn't caused any irritation- it actually created a nicer texture and softness to my face. It's been about two days since i've made and jarred the water. This morning I noticed the odor wasn't as nice as the first day. Is it still safe to use?
