Topical medications are remedial, drug-containing substances that are generally applied to surfaces of the body. Topical medications come in a variety of forms which include creams, lotions, gels, patches, and ointments. Ointments, specifically, are highly viscous medications that are prepared from materials such as paraffin wax, beeswax, or vegetable oils. Most ointments contain very little water, making them ideal for moisturizing and protecting the affected area. Bacitracin zinc is an antibiotic that is commonly incorporated into ointments. This drug is used for preventing infections in minor skin injuries when applied topically.
The regular consumption of dairy products provides numerous health benefits, such as strengthening bone health, encouraging proper digestion, and reducing the risk of certain infections.

Natural water properties and composition vary geographically depending on factors such as geology and climate. One of these properties is water hardness. Water hardness is the concentration of dissolved minerals in water. Hardness is primarily caused by calcium and magnesium, but iron, silica, and other metals can also contribute. Some areas of the world have natural, mineral rich hard water, while others have water very low in mineral concentrations, or soft water. Scaling and build-up are adverse effects due to the high mineral content of hard water, costing homeowners money in maintenance and care of their appliances. Homes that have hard water experience discoloration in toilets and showers, decreased water pressure, decreased water heater efficiency, and lower soap effectiveness in cleaning dishes and clothes.
