Using salt to separate alcohol from hand sanitizer
As the concentration of salt increases, its ionic components compete with the alcohol for space around the water molecules. Eventually, the salt outcompetes the alcohol, causing it to separate from the solution. The end result is a dense plug of water and gel at the bottom, with mostly pure ethanol floating on top. This process can be further aided by using a coffee filter to obtain purer alcohol.
However, it is important to note that this method may not yield completely pure alcohol, and there may still be some impurities present. Additionally, the process of separating alcohol from hand sanitizer can be dangerous as alcohol is flammable and the process involves working over a heat source. Therefore, it is crucial to exercise extreme caution if attempting any such separation or distillation processes.
While the salt method is a popular topic of discussion, it is important to emphasize that consuming hand sanitizer or attempting to extract alcohol from it for any purpose other than its intended use is unsafe and strongly discouraged. Hand sanitizer contains high concentrations of alcohol, typically ethanol, which can cause severe health risks if ingested, including acute ethanol intoxication, which can lead to life-threatening consequences.

Distillation of hand sanitizer
Distilling alcohol from hand sanitiser can be done in several ways. One method is to use salt to separate the alcohol, which has a hydrophobic region, from the other ingredients in the hand sanitiser. As the concentration of salt increases, its ionic components compete with the alcohol for space around the water molecules. Eventually, the salt outcompetes the alcohol, causing it to separate from the solution. This process results in a dense plug of water and gel at the bottom and mostly pure ethanol floating on top. The ethanol can then be filtered using a coffee filter. However, it should be noted that this method may not result in pure alcohol, and further distillation may be required to remove any contaminants.
Another method to distill alcohol from hand sanitiser is through the process of distillation itself. Distillation involves using a heat source to separate the components of a mixture based on their different boiling points. In the case of hand sanitiser, it typically contains ethanol or isopropyl alcohol as the active ingredient, along with inactive ingredients such as a polymeric thickener and perfume. By applying heat, the alcohol can be separated from the other ingredients, as it has a lower boiling point. The distilled alcohol can then be collected and purified further if needed.
When distilling alcohol, it is important to exercise caution as alcohol is flammable, and a heat source is required for the process. Additionally, it is crucial to start with high-proof alcohol to ensure that the final product has a sufficiently high alcohol concentration to be effective as a hand sanitiser. The CDC recommends using a solution of 60%-90% ethyl alcohol for hand sanitisation.
To further purify the distilled alcohol, additional steps can be taken. One suggestion is to use a distillation set, which typically includes flasks and a heat source. This allows for the removal of any remaining impurities through subsequent distillations. It is also important to consider the inactive ingredients in the hand sanitiser, as some may have high boiling points and require additional steps for separation.
Overall, distilling alcohol from hand sanitiser requires careful consideration of the process, the use of appropriate equipment, and adherence to safety precautions to ensure a successful and safe outcome.

Safe disposal of hand sanitizer
Hand sanitizers have become a staple in our daily lives, especially in the post-pandemic era. However, as their use has increased, so has the question of their safe disposal. Improper disposal of hand sanitizers can lead to serious environmental and health hazards.
The primary ingredient in hand sanitizers is alcohol, which is beneficial in eliminating bacteria but can degrade over time. Expired hand sanitizers are considered hazardous waste due to the presence of alcohol, which is flammable and can pose a fire risk. In addition, the chemicals in hand sanitizers can contaminate soil and water sources, altering the soil's pH and nutrient content and harming plants and aquatic ecosystems. Therefore, it is crucial to dispose of hand sanitizers responsibly.
For households, the Environmental Protection Agency (EPA) recommends not disposing of hand sanitizers in the regular trash or pouring them down the drain. Instead, hand sanitizer waste should be brought to a household hazardous waste drop-off location or event for proper management. This is because ignitable materials, such as alcohol, can cause fires and explosions in water pipes and sewer systems.
Businesses and institutions should also adhere to federal and state-level regulations for the safe disposal of hand sanitizers. Happen Ventures, for example, offers services to help enterprises comply with the necessary norms. Recycling is encouraged whenever possible, but it must be done in compliance with legitimate recycling regulations.
In summary, the safe disposal of hand sanitizers is essential to protect the environment and human health. By following the recommended guidelines and regulations, individuals, businesses, and institutions can play a responsible role in safeguarding our planet and future generations.

The chemistry behind adding salt to separate alcohol
While it is possible to separate alcohol from hand sanitizer by adding salt, it is important to note that the alcohol obtained through this method will still be impure. This process of separation relies on the chemical properties of salt and its interaction with water and alcohol.
When salt is added to a mixture of water and alcohol, it competes with the alcohol for the water molecules. Salt is an ionic compound, meaning it is made up of electrically charged molecules called ions. These ions are attracted to the water molecules and dissolve in them, a process known as solvation. As the concentration of salt increases, its ionic components compete with the alcohol for space around the water molecules. Eventually, the salt outcompetes the alcohol, causing the alcohol to become less soluble in the water-alcohol mixture. This results in the alcohol forming a separate layer on top of the water. The process is called "salting out" or "salt-induced phase separation."
The polarity of water molecules plays a crucial role in this process. Water molecules have both positive and negative polar ends, which are attracted to the negative chloride ions and positive sodium ions in salt, respectively. This attraction between the water molecules and the ions in salt leads to the dissolution of salt in water. On the other hand, alcohol has a hydrophobic region and is less polar than water, making it less soluble in salt.
Additionally, the presence of salt increases the density of the water. As more salt is added, the water becomes significantly denser, further contributing to the separation of the alcohol and water layers. In the context of hand sanitizer, which typically contains ethanol, a polymeric thickener, and perfume, adding salt causes the thickener to separate, resulting in a dense plug of water and gel at the bottom and mostly pure ethanol floating on top.
It is worth noting that while salt can effectively separate alcohol and water, it may not result in absolute purity. Distillation or freeze distillation techniques can be employed to further purify the ethanol and remove any remaining water. However, these methods require additional equipment and a heat source, which introduces safety concerns due to the flammability of alcohol. Overall, the process of adding salt to separate alcohol from hand sanitizer involves a combination of chemical interactions, solubility, and density differences, resulting in the separation of ethanol from the other components of the hand sanitizer.

The cost of distillation
Distillation is a process that involves separating components of a mixture by selective boiling and condensation. While it is often used to purify water, it can also be used to separate alcohol from a mixture, such as in the case of hand sanitizer. The cost of distillation can vary depending on the scale, purpose, and technology used.
For laboratory settings, solvent distillation units can be a significant capital expenditure, typically exceeding $2,500. However, the upfront costs of purchasing such equipment can be offset by the long-term economic benefits. For example, recycling solvents onsite can reduce purchase order costs by 90-95%savings in solvent purchases, labour, and waste disposal. In some cases, labs have been able to recoup the cost of a laboratory solvent recycler in less than two years.
On a larger scale, distillation systems can be used to produce distilled water for various applications. For instance, H2o Labs offers a vapor compression water distillation system that can produce 800 to 6,000 gallons per day at a production cost of 0.5 cents per US gallon. This system has a quick payback period, especially for water stores that sell large volumes of distilled water.
Distillation is also commonly used in desalination processes to convert saline water into fresh water. While desalination can be energy-intensive and costly, advancements have been made to improve energy efficiency. Multiple-effect distillation (MED) utilizes a series of steps to increase efficiency, although it has limitations in terms of maximum temperature and the number of effects. Other methods, such as vapor-compression evaporation and membrane distillation, offer alternative approaches to desalination.
It is important to note that distilling alcohol from hand sanitizer can be dangerous due to the flammable nature of alcohol. Always exercise caution when working with heat sources and flammable substances.
