Castor seed oil, listed as RICINUS COMMUNIS SEED OIL, is the fixed oil obtained from the seeds of Ricinus communis, the plant commonly called castor bean.

RICINUS COMMUNIS SEED OIL: what it is

Castor seed oil, listed as RICINUS COMMUNIS SEED OIL, is the fixed oil obtained from the seeds of Ricinus communis, the plant commonly called castor bean. The species belongs to the Euphorbiaceae family, so this name points to a seed-derived plant oil rather than to a general reference to castor or to an unspecified plant material.

As a seed oil, it differs from a leaf extract, an isolated fragrance material, or an essential oil from the same plant. It is the oily fraction obtained from the seed and may appear in skin-care products whose texture and application include an oil phase.

RICINUS COMMUNIS SEED OIL: what it does in cosmetics

In cosmetics, castor seed oil may help a product spread with a softer, smoother slip and leave the skin feeling less rough; that is the practical meaning of skin conditioning here. This concerns the feel and finish of a formula, not proof that the oil on its own treats acne, dark spots, wounds, or other skin diseases.

RICINUS COMMUNIS SEED OIL can also contribute to a product's perfumed profile. Its presence does not mean every product containing castor oil will have a noticeable scent, because the perceived fragrance depends on the other ingredients and on the amount used. No clinical topical efficacy claim for the isolated oil is made here.
