Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Topical formulations need ingredients to maintain moisture and prevent the formulation from drying out.
Step 2: Detailed Explanation:
Glycerin (or glycerol) is a polyol that is hygroscopic, meaning it attracts and holds water.
In external applications like creams and lotions, it acts as a humectant by keeping the skin hydrated and preventing the product from hardening due to evaporation.
Step 3: Final Answer:
Glycerin is primarily used as a humectant in topical products.
