These surfactants are molecules that have each lipophilic and hydrophilic, or fat soluble and water soluble components. The fat soluble portion of the item clings to the oil and dirt as the water soluble component allows the lipophilic element to be washed away. Detergents for dishes and clothes function in quite considerably the identical way but will have diverse components that make them much more harsh for use on tough, solid surfaces.

Due to the fact 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 best layer of the skin. This makes the the item appear blue or green in the container and alter to red when applied to the lips.
