Question

which of the following ointment bases is most prone to mold growth? water-soluble emulsion absorption oleaginous

Explanation:

Mold growth requires moisture. Emulsion ointment bases (like oil - in - water or water - in - oil emulsions) contain water phases. Water - soluble bases also have water, but emulsion bases have a more complex structure that can retain moisture better for mold. Oleaginous (oil - based) and absorption bases (which are oil - based with water - absorbing components but less free water) have less available water for mold. Among these, emulsion bases, due to their water - containing emulsion structure, provide a more favorable environment for mold growth compared to the others.

Answer:

B. Emulsion
