What are the two types of absorption bases?

Explanation:
Absorption bases are designed to take up water when used in topical formulations, so they come in two forms. One type is anhydrous absorption bases, which contain little or no water to begin with but have the capacity to absorb water and form a water-in-oil emulsion if water is added. The other type is already a water-in-oil emulsion themselves, meaning they’re emulsified bases with dispersed water droplets that can still incorporate additional water. Together, these two forms—anhydrous absorption bases and water-in-oil emulsions—constitute the absorption bases.
