Petrolatum and zinc oxide are examples of:

• A. Moisturizers.
• B. Emollients.
• C. Skin cleansing agents.
• D. Moisture barriers.

Answer: (D)

Petrolatum and zinc oxide protect skin by forming a barrier against moisture and irritants. Petrolatum sits on the skin as an occlusive layer, reducing water loss, while zinc oxide creates a protective film that shields the skin from moisture and friction. Incontinence care focuses on preventing moisture-related dermatitis, so describing these as moisture barriers best captures their primary role, even though they also have softening properties. They’re not cleansing agents, and while they can help with skin comfort, their protective barrier function is what sets them apart.
