PEG-40 Hydrogenated Castor Oil
Used for conditioning, thickener, and to keep product from separating into oil and water components. This is made from Castor oil that's been thickened by hydrogenation, then processed with polyethylene glycol.
This is an off-white solid that's water soluble in warm water, considered to be safe and mild in cosmetics. The main difference between PEG-40 Hydrogenated Castor Oil and PEG-40 Castor Oil is that the Hydrogenated Castor Oil is more solid at room temperature, and it has less of a "Castor" scent. [Hunting (Conditioning) pg 318].
