PRODUCT INTRODUCTION
description
Castor oil is characterized by its pale-yellow or nearly colorless appearance, presenting as a transparent, viscous liquid. It has a faint mild odor and a taste that some may find nauseating. The density of castor oil is 0.95 g/cm³, indicating its substantial mass per unit volume. Chemically, it is a complex mixture of glycerides, predominantly composed of ricinolein, which is the glyceride of the unique fatty acid ricinoleic acid.
