Acetone is a commonly used and relatively inexpensive solvent that can be found in many households. Its chemical formula is (CH₃)₂C=O, and it is also known as dimethyl ketone or propanone. Acetone is often used as a nail polish remover and is sold in plastic bottles. Interestingly, acetone has the ability to dissolve certain types of plastics while leaving others unaffected. The impact of acetone on a particular plastic depends on the chemical makeup of the plastic and factors such as concentration, temperature, and exposure time. Some plastics, such as PVC and styrofoam, are susceptible to acetone and can be dissolved or damaged, while others, like polyethylene and polypropylene, are resistant to its effects. Understanding the chemical resistance of different plastics is crucial when selecting materials for products that may come into contact with acetone.

Acetone dissolves some plastics but not others
Acetone does not melt all plastics. It dissolves or is dissolved by many plastics, but not all of them. The impact of acetone on plastics depends on the chemical makeup of the plastic and other factors like concentration, temperature, length of exposure, frequency, and the presence of other chemicals.
Some plastics that are dissolved by acetone include polystyrene, PVC (polyvinyl chloride), acrylic, polycarbonate, ABS, and assorted copolymers. Acetone containers are often made of plastics that are not affected by acetone, such as polyethylene, polypropylene, or Teflon.
The chemical resistance of a plastic to acetone can be determined using a plastic chemical resistance chart. This chart helps identify plastics that are resistant to acetone and those that are not. For example, acetal is listed on the chart as having a moderate effect when exposed to acetone, while other plastics may experience severe effects, especially at high concentrations and over long periods.
When choosing a plastic for custom parts or products, it is crucial to consider the impact of acetone and other chemicals. Selecting an incompatible plastic could lead to the dissolution of the product over time. Therefore, consulting the plastic chemical resistance chart is essential to ensure the product's longevity and durability.
In summary, while acetone can dissolve certain plastics, it is important to note that not all plastics are affected. The specific type of plastic and various environmental factors determine the impact of acetone on the material. By referring to the plastic chemical resistance chart, one can make informed decisions when working with plastics and ensure the suitability and longevity of the chosen material.

Plastics with dissimilar chemical makeups to acetone remain unaffected
It is important to note that acetone does not melt plastic; rather, it dissolves certain plastics while having no impact on others. The solubility of a substance in a given solvent is governed by the "like dissolves like" rule of thumb. This rule suggests that two substances will mix if they are similar. For example, water is an excellent solvent for wood alcohol because they share similarities.
The chemical makeup of plastics that are resistant to acetone is too different from acetone to be affected by it. While these plastics may experience a minor effect upon contact with acetone, they will not dissolve.
However, it is important to note that there are many variables that can affect the resistance of plastics to acetone, such as concentration, temperature, length of time, frequency, and the presence of other chemicals. Therefore, it is always a good idea to consult a plastic chemical resistance chart when choosing a plastic for a specific application.

Acetone is sold in metal containers to avoid damage
Acetone is a highly flammable liquid with a sweet odour. It is a powerful solvent that can dissolve some plastics. However, not all plastics are affected by acetone. The impact of acetone on plastics depends on various factors, including the concentration, temperature, length of exposure, frequency of contact, and the presence of other chemicals.
Some plastics, such as PVC (polyvinyl chloride) and styrofoam (polystyrene), are known to break down when exposed to acetone. On the other hand, plastics like polyethylene, polypropylene, and Teflon are more resistant and can be used to create acetone containers.
To avoid any potential damage or safety hazards, acetone is typically sold in metal containers. Metal containers provide a more reliable barrier against leakage or accidental spills, which could pose a significant risk due to acetone's flammable nature. Additionally, metal containers can better withstand the volatile nature of acetone and its potential for causing eye and skin irritation.
While acetone is often sold in metal containers for safety reasons, some companies also offer acetone in plastic bottles, specifically for its use as a nail polish remover. These plastic bottles are typically made of high-density polyethylene (HDPE), a type of plastic that is resistant to acetone. By using HDPE bottles, companies can safely package and distribute acetone without the risk of container damage or leakage.
In summary, acetone is sold in metal containers to mitigate the risk of damage to the product and its surroundings. Metal containers provide a safer option due to acetone's flammable nature and its ability to dissolve certain plastics. However, with the appropriate choice of acetone-resistant plastic, such as HDPE, it is possible to safely package acetone in plastic bottles for specific applications, such as nail polish remover.

Some companies sell acetone in plastic bottles made of HDPE
It is a common misconception that acetone melts plastic. In reality, acetone dissolves or is dissolved by many plastics, but not all. Some companies sell acetone in plastic bottles made of HDPE (high-density polyethylene). This type of plastic has a negligible reaction with acetone, meaning the acetone will not dissolve the plastic bottle.
The chemical makeup of HDPE is different from acetone, which is why there is little to no reaction between the two. However, it is important to note that some variables can affect the resistance of plastics, such as concentration, temperature, length of time, frequency, and the presence of other chemicals. For example, acetone will have a moderate effect on acetal, a type of plastic listed on the chemical resistance chart. If acetone comes into regular contact with acetal, it will damage the plastic's surface, softening it, smearing it, or even dissolving it.
The plastic chemical resistance chart is a useful tool for determining which plastics are compatible with acetone. It is important to consult this chart before choosing a plastic for custom parts or storing acetone. Polypropylene is another type of plastic that does not react with acetone and is commonly used for milk jugs.
While HDPE and polypropylene are suitable for storing acetone, other plastics, such as PVC and styrofoam, should be avoided as they will break down when exposed to acetone. It is worth noting that some people have reported successfully storing acetone in plastic food containers without any issues, but the specific type of plastic used in these containers is unclear.
Overall, when it comes to storing or using acetone, choosing the right plastic is crucial. HDPE and polypropylene are good options as they do not react significantly with acetone, ensuring the safety and longevity of the product.
