Storing castor oil in a plastic bottle is generally considered safe, as long as the plastic is of food grade quality and specifically designed to store oils. However, for long-term preservation and to maintain the oil's purity, using dark glass bottles is preferable. Glass is inert and does not interact with the oil, thus ensuring the oil's integrity over time. If using plastic, ensure it is BPA-free and suited for food storage to avoid chemical leachate.
