One of the most commonly used preservatives in hunting urine is propylene glycol. This colorless and odorless liquid serves as an attempt to slow bacterial and fungal growth, effectively extending the shelf life of the urine. By inhibiting microbial activity, propylene glycol addition attempts to maintain the potency of the scent.
In addition to propylene glycol, some hunting urine manufacturers incorporate food-grade preservatives like potassium sorbate and sodium benzoate into their formulations. These additives serve as layers of defense against spoilage, attempting to increase the longevity of the scent product. By preventing the growth of mold and yeast, potassium sorbate and sodium benzoate help preserve the freshness and effectiveness of the urine under varying storage conditions.
