Color
Your castor oil most likely has gone bad if the color has changed. A light yellow hue ought to be present in the oil. It has probably oxidized and is no longer functional if it has turned brown or black.
Smell
It has also likely deteriorated if your castor oil smells rancid. The aroma of castor oil should be mild and nutty. It has likely spoiled if it smells bad or sour. Rancidity is one of the main problems with expired oils.
