Surfactants are substances that reduce water resistance and increase the surface tension of liquids, making them more absorbent or slippery. They play a critical role in many biological processes, from the lubrication of joints to the transport of nutrients through the bloodstream.

As a nurse, it is important to be familiar with the different types of surfactants that exist and how they can affect patients. Surfactants can be classified into three categories based on their chemical structure: hydrophobic (soluble in water), hydrophilic ( insoluble in water), and non-soluble ( neither soluble nor insoluble).
One type of surfactant that nurses may come across is sodium lauryl sulfate (SLS). SLS is a polar molecule that has hydrophilic groups on both ends. When applied to a patient’s skin, SLS can help to reduce friction and improve moisture absorption. However, SLS can also have negative effects on the skin and can cause irritation if applied too frequently or in high concentrations.
Another type of surfactant that nurses may encounter is ethylene glycol diisocyanate (EGDI). EGDI is a non-polar molecule that has hydrophilic groups on one end and hydrophobic groups on the other. This means that it is highly effective at reducing friction and improving moisture absorption without causing skin irritation. However, EGDI can also be harmful to patients who are allergic to its ingredients, such as benzene or formaldehyde.
A third type of surfactant that nurses may encounter is sodium cocoamide (CCO). CCO is a polar molecule that has hydrophilic groups on both ends. Like SLS and EGDI, CCO is highly effective at reducing friction and improving moisture absorption. However, CCO can be toxic to humans if ingested in large amounts or prolonged exposure to high temperatures.
In addition to these three main categories of surfactants, there are many other surfactants that nurses may encounter depending on the specific treatment plan for each patient. For example, detergents may contain surfactants to break up and remove dirt and bacteria from clothing or surfaces, while moisturizers may contain surfactants to help prevent dryness and flakiness.

Overall, being familiar with the different types of surfactants that exist is crucial for nurses to provide effective care to their patients. By understanding how surfactants work and how they can impact patients’ skin and overall health, nurses can help to ensure that patients receive the best possible treatment while minimizing any potential harm.
