Multiple Choice

Hydrophilic ointments require antimicrobial preservatives.

Explanation:
Hydrophilic ointments contain water or are water-washable, which creates a medium in which microorganisms can grow. In non-sterile topical products, preservatives are added to inhibit bacteria and fungi and to maintain safety and stability during storage. If the product is sterile, used in single-dose packaging, or otherwise exempt from microbial concerns, a preservative might not be required, but under typical non-sterile conditions, a preservative is needed. This is why the statement is considered true.
