As a specialist in chemical safety and toxicology, I'd like to address the question of whether antifreeze is absorbed through the skin. Antifreeze, commonly used in automotive applications, is a mixture of ethylene glycol and water, along with various additives designed to prevent corrosion and other issues. The primary concern with antifreeze is its potential toxicity, particularly if ingested.
Ethylene glycol is a key component of antifreeze and is known for its sweet taste, which can be attractive to animals and children. It is important to note that while ethylene glycol is toxic when ingested, the risk of toxicity through skin absorption is significantly lower. The human body has a remarkable ability to metabolize and eliminate small amounts of substances that are absorbed through the skin. This process is facilitated by the skin's natural barrier function, which is designed to protect the body from harmful substances.
When ethylene glycol is mixed with water, as it is in most antifreeze formulations, the rate of skin absorption is further reduced. Water acts as a diluent, slowing down the absorption process. Moreover, the skin acts as a semi-permeable barrier, allowing only certain substances to pass through at varying rates. The molecular structure and size of ethylene glycol, along with the protective barrier provided by the skin, contribute to the slow absorption rate.
It is also worth mentioning that the concentration of ethylene glycol in antifreeze is typically around 50% to 60%, with the remainder being water and additives. The presence of these additives can further influence the rate of absorption through the skin. Some additives are specifically designed to reduce the toxicity and improve the safety profile of the product.
Under normal use scenarios, where exposure is limited and the skin is intact, the risk of toxic effects from ethylene glycol through skin absorption is minimal. The body is capable of effectively eliminating the small amounts that may be absorbed. However, it is crucial to exercise caution and avoid prolonged or direct contact with antifreeze, especially if the skin is damaged or compromised.
In cases where the skin is not intact, such as with cuts or abrasions, the risk of absorption may be higher. It is also important to consider that repeated or excessive exposure could potentially lead to an accumulation of ethylene glycol in the body, which could pose health risks.
In summary, while ethylene glycol in antifreeze can be absorbed through the skin, the rate of absorption is relatively slow, and the body is capable of effectively eliminating the small amounts that are absorbed. The presence of water and additives in antifreeze formulations further reduces the risk of skin absorption. However, it is always best to handle antifreeze with care and to take precautions to minimize exposure.

The body is able to eliminate effectively the small amount that is absorbed. When mixed with water, as in automobile antifreeze, skin absorption of ethylene glycol is even slower. Ethylene glycol, therefore, does not cause toxic effects in humans through skin absorption under normal use scenarios.
