Lotions are applied to external skin with bare hands, a brush, a clean cloth, cotton wool, or gauze. While lotion may be used as a medicine delivery system, many lotions, especially hand lotions and body lotions are meant instead to simply smooth, moisturize and soften the skin. Dermatologists can prescribe lotions to treat or prevent skin diseases. It is not unusual for the same drug ingredient to be formulated into a lotion, cream and ointment. Since health care workers must wash their hands frequently to prevent disease transmission, hospital grade lotion is recommended to prevent skin dermatitis caused by frequent exposure to cleaning agents in the soap. A 2006 study found that application of hospital grade lotion after hand washing significantly reduced skin roughness and dryness. Care must be taken not to use consumer lotions in a hospital environment, as the perfumes and allergens may be a danger to those who are immunodeficient.
Most lotions are oil-in-water emulsions using a substance such as cetearyl alcohol to keep the emulsion together, but water-in-oil lotions are also formulated. Since thickness and consistency are key factors in lotions and creams, it is important to understand the manufacturing process that determines viscosity. Emollients and lubricants are dispersed in oil with blending and thickening agents. Perfume, color and preservatives are dispersed in the water cycle. Active ingredients are broken up in both cycles depending on the raw materials involved and the desired properties of the lotion or cream.
