In vanishing cream formulations, glycerin or sorbitol are used as which type of ingredient?

Explanation:
Glycerin and sorbitol act as humectants. They are hygroscopic polyols that attract and hold water, helping to keep the skin hydrated and the cream film moist. In vanishing creams, which are light oil-in-water emulsions that dry down after application, humectants bind water from the air and from the deeper skin layers, reducing transepidermal water loss and preventing the film from feeling dry as volatile components evaporate. They aren’t primarily emulsifiers, preservatives, or thickeners, though they may modestly influence viscosity. So the best fit is humectant.
