Something that is hydrophilic, is a material that has a strong affinity for water, and is capable of interacting with it through hyrdrogen bonding. Some hydrophilic substances can attract water from the air and collect it into a dew drop, which is what can usually be seen on grass in the morning or spider webs. A hydrophilic molecule is typically charged and capable of hydrogen bonding, which allows the molecule to dissolve in water more easily. When some hydrophilic substances do not dissolve in a mixture it becomes known as a colloid soap. It takes this form because the molecule have a hydrophobic head and a hydrophilic tail making it able to dissolve in waters and oils.
