What is glycerin anhydrous used for?

Answer 1

Glycerin has hundreds of uses in chemistry and manufacturing. The kind you buy for home use is commonly used as a skin lotion (it is the base ingredient in many skin lotions). Lotions can be expensive and can contain glycerin plus dyes, perfumes, spreaders and alcohols. The additives can cause Allergies and the alcohols can cause dryness so many people use just the glycerin as a moisturizer. "Anhydrous" just means it has very little or no water (is nearly pure glycerin).
