What type of substance is lanolin classified as?

Lanolin is classified as a humectant, which is a type of substance that helps retain moisture. This is particularly valuable in various applications, including cosmetics and skin care products, where it enhances skin hydration by attracting and binding water to the surface of the skin. Lanolin is derived from the wool of sheep and is known for its ability to create a protective barrier while allowing the skin to maintain moisture levels.

In the context of funeral service, understanding the properties of humectants like lanolin can assist professionals in preparing the deceased and ensuring that their appearance is preserved during the viewing process, as it can help maintain the skin's moisture and prevent it from drying out. This is crucial for providing families with a dignified and respectful viewing experience.
