How can a de-icer be used in food or in cosmetics?
It is not the “de-icer” that is used; the different “natural” functionalities of propylene glycol make it the preferred substance in both applications. In the de-icer it is the ability to reduce the freezing point, in cosmetics the ability to dissolve, emulsify, or carry active ingredients in substances. In the de-icer industrial propylene glycol is used, in the cosmetic it is of course propylene glycol USP/EP (pharmaceutical grade). It is the multifunctionality of propylene glycol that offers this wide variety of uses.
