Final answer:
Compatible levigating agents for anhydrous absorption include glycerin, mineral oil, and propylene glycol. These agents can mix with anhydrous substances without adding moisture.
Step-by-step explanation:
Anhydrous absorption is a process that involves the removal of water or moisture from a substance. Levigating agents are substances that facilitate the wetting and mixing of powders to form a smooth paste. In the case of anhydrous absorption, compatible levigating agents are those that can effectively mix with the anhydrous substance without introducing moisture.
Glycerin is a viscous liquid that can be used as a levigating agent. It has the ability to mix with anhydrous substances, such as powders, without adding moisture. Mineral oil is another levigating agent that can be used for anhydrous absorption. It is a non-polar substance that does not contain water, making it suitable for mixing with anhydrous substances.
Propylene glycol is a clear, viscous liquid that can act as a levigating agent for anhydrous absorption. It is compatible with anhydrous substances and does not introduce moisture. In summary, when performing anhydrous absorption, it is important to use levigating agents that are compatible with the anhydrous substances being used. Glycerin, mineral oil, and propylene glycol are examples of compatible levigating agents that can facilitate the mixing and wetting of anhydrous powders without introducing moisture.
