Shampoos and soaps are products that normally include some type of fragrance and clean the skin by the use of surface-active agents, or surfactants. These surfactants are molecules that have each lipophilic and hydrophilic, or fat soluble and water soluble parts. The fat soluble portion of the solution clings to the oil and dirt as the water soluble portion enables the lipophilic component to be washed away. Detergents for dishes and clothing perform in pretty much the very same way but will have different components that make them a lot more harsh for use on tough, strong surfaces. It is typically not a very good idea to try and use these detergents on the physique and hair, for it can lead to irritation.
Lipstick is another cosmetic item that includes hydrophilic properties. They are manufactured by combining wax, a non-volatile oil such as beeswax with castor oil, and water.

Simply because of its lipophilic properties, lipstick wont dissolve on the lips when exposed to saliva or liquid from drinks. Other lipsticks will have a dye in them that react to amino acids on the prime layer of the skin. This tends to make the the product seem blue or green in the container and adjust to red when applied to the lips.

This is when we need to have the support of a moisturizer. When the skin becomes dry and scaly, moisturizers can help by preventing additional water loss, known as occlusion, and by adding humectants, substances that increase the hydrophilic properties of the skin. Humectant moisturizers include substances such as alpha hydroxy acids or glycerine and add moisture to the top layer of skin although occlusive moisturizers form a waterproof layer over the skin that reduces moisture and allows the bodys organic rehydration method to return the layer to a regular level.
