Isopropyl alcohol has been a household favorite for its multipurpose use, ranging from cleaning surfaces, disinfecting wounds, and manufacturing various products. However, the question that has been on the minds of many users is, do isopropyl alcohol expire? While the answer is not straightforward, this article aims to provide you with all the information you need to know about the shelf life of Isopropyl alcohol.Firstly, it's crucial to understand what isopropyl alcohol is and how it's produced. Isopropyl alcohol, also known as rubbing alcohol, is a colorless and flammable solution. It's made from a combination of water, propane, and propylene using a distillation process. The purity of the solution, ranging between 70% to 99%, determines its effectiveness.The ‘expiration’ of isopropyl alcohol is a confusing topic since it doesn't go 'bad' per se, but its potency reduces over time. If stored correctly, most manufacturers of rubbing alcohol say that their products can last up to three years. Still, this timeframe does not account for the loss of potency.Several factors can affect the shelf life of isopropyl alcohol, including the container, temperature, and exposure to light. Most rubbing alcohol bottles come in plastic or glass containers, but plastic containers can develop cracks over time, allowing air to seep in, which can reduce the effectiveness of the solution. On the other hand, glass containers provide a better indication of the solution's deterioration as the product's transparency can indicate color or odor changes.Temperature is also an essential factor in the shelf life of isopropyl alcohol, with lower temperatures being more optimal for storage. High temperatures cause the alcohol to evaporate or decompose, rendering it less potent. Avoid storage in a warm environment or direct sunlight; instead, store the rubbing alcohol in a cool, dry place. The storage place should be away from heat sources, flame, and ignition sources, as rubbing alcohol is highly flammable.In conclusion, isopropyl alcohol does expire or rather lose its potency over time. But if stored correctly, it can still be effective even beyond its ‘expiration’ date, depending on the concentration of the solution. It's always essential to check the expiration date and do a spot test before use.As rubbing alcohol is a versatile product, we reached out to {brand name}, a reputable manufacturer of isopropyl alcohol in the US, to get their take on the shelf life of rubbing alcohol.
