Cold Pressed Castor Oil is a pure virgin transparent Castor Oil extracted in its natural form by pressing seeds without using steam cooking. This helps to preserve herbal and healing properties. It is considered as one of the most valuable laxatives in pharmacy. Castor beans contain nutrient-rich oil, which makes up 35%-55% of their weight. When pressure is applied to the beans, they release this oil and all of the nutrients, minerals and essential fatty acids which it contains. No heat is required to extract the oil. Simply pressing the beans provides luxurious oil, packed full of nutrients. Appearance Clear, Pale Yellow, Viscous Liquid Odour Very slight, Characteristic Moisture 0.3 Max. Hydroxyl Value 150 Max.
