Can I be sure that industrial propylene glycol will not be used for pharmaceutical applications?
In fact, the quality and purity of both industrial propylene glycol and propylene glycol USP/EP (pharmaceutical grade) is very high. In addition, for propylene glycol USP/EP intended for use in pharmaceutical applications, utmost care is placed on fulfilling the specific strict rules for the production, transport and hygiene of propylene glycol USP/EP to be used in sensitive applications like in food or cosmetics. All members of the Cefic Propylene Oxide / Propylene Glycol business group do not support the use of industrial propylene glycol for use in pharma, food, animal feed and cosmetic/personal care applications.
