Here's why it's used in these products:
* Soap: Glycerin acts as a humectant, attracting and retaining moisture, making soap feel softer and less drying.
* Cosmetics: Its moisturizing properties make it a popular ingredient in lotions, creams, and even toothpaste. It can also help improve the texture and consistency of cosmetics.
* Inks: Glycerin helps inks flow smoothly, prevents them from drying too quickly, and contributes to their vibrant colors.
While other transparent liquids like water and alcohol are also used in these products, glycerin is a key component due to its unique properties.
