In this construction, "glycerin-soaked" is an adjective.

Can you please explain why?
Answered by Ms. Sue
Glycerin-soaked is hyphenated -- making it one word. It's used as an adjective modifying cotton. It tells what kind of cotton is being used.

When the word "glycerin" stands alone, it is indeed a noun.

Example: Glycerine is a colorless, odorless, syrupy, sweet liquid.
