Which characteristic is associated with hydrophilic substances?

• A. They repel water
• B. They absorb moisture
• C. They're greasy
• D. They require thickening agents

Answer: (B)

Hydrophilic substances are defined by their affinity for water, meaning they have the ability to absorb moisture readily. This characteristic arises from the polar nature of hydrophilic molecules, allowing them to interact and form hydrogen bonds with water. Unlike hydrophobic substances, which repel water and tend to be greasy or oily, hydrophilic substances are often used in various applications, including cosmetics and skincare, to help with moisture retention and hydration. Therefore, the ability to absorb moisture is a key trait that differentiates hydrophilic substances from others.
