Vegetable glycerin is a clear, odorless liquid derived from plant oils, commonly sourced from soybeans, coconut, or palm oil. It is a type of sugar alcohol that is often used in food, cosmetics, and pharmaceuticals due to its ability to retain moisture and provide a sweet taste without the calories of sugar. In addition to its use in various products, vegetable glycerin is also known for its versatility as a humectant, which means it helps to keep things moist. It is safe for consumption and is often found in products like e-liquids, lotions, and even some baked goods, making it a popular ingredient in many industries.
