Composition and Properties
Petroleum distillates are derived from the refinement of fossil fuels. They undergo rigorous purification processes to meet standards set by the industry and government regulatory agencies. In cosmetics and pharmaceutical products, they serve as moisturizers and protectants.
Distillates are hydrophobic, meaning they repel water. Like lipid-based lubricants, they can create a barrier between the mucosal membrane of the fist chute and the hand, penis, or other instrument of penetration. This barrier also prevents the passage of moisture and large molecules between the chute to the blood stream.
QUICK REFERENCE
Distillates come in various viscosities are rarely used alone as single-ingredient lubes. Most liquid distillates, such as mineral oil, improve the texture of lube and increase lubricity. Semi-solid distillates such as Vaseline may induce drag within the fist chute. This drag may be pleasurable or uncomfortable based on personal tastes and preferences.
In the extensive douching processes needed for fisting, applying a dab of semi-solid distillate (such as Albolene, Aquaphor, or petrolatum) to the anal canal decreases tissue damage from the force of water expelled from the douche nozzle.
