Glycerol in lactophenol cotton blue stain serves primarily as a humectant, helping to retain moisture in the specimen preparation. This property prevents the sample from drying out during observation under a microscope. Additionally, glycerol aids in the dispersion of the cotton blue dye, enhancing the visibility of fungal structures by providing a clearer medium for viewing.
