ABSTRACT:
A process for manufacturing a liquid evaporation retardant product that combines isopropanol-water azeotrope with up to 5% octadecanol by weight of the total solution, and upon which improved capability to remain precipitate free in the event of colder temperatures than normal is conferred by adding n-butanol at 10% by weight of the pre-made basic product.
