Pure cold-pressed castor oil
Plain cold-pressed castor oil is the workhorse of this whole niche: a single-ingredient oil people commonly use as a rich occlusive moisturizer for dry patches, cuticles, and rough skin. Because the ingredient list is one line long, the label details do the differentiating — "cold-pressed" refers to how the oil was extracted, "hexane-free" to what solvents were not used, and the packaging (glass versus plastic, dropper versus flip cap) affects day-to-day use more than marketing copy admits.
The table below ranks current Amazon listings by price per fluid ounce, since bottle sizes run from 2 oz droppers to 32 oz jugs. Sizes are parsed from listing text, so double-check the label before buying. Castor oil is heavy and can irritate or clog pores on some skin — patch-test first, keep it off broken skin, and talk to a dermatologist about any ongoing skin condition.
