Definition of Lotion
Lotion is a low-viscosity topical preparation intended for application to the skin. It is a cosmetic product that is designed to moisturize, soften, and smooth the skin. Lotions are less viscous than creams and gels, and they contain a larger percentage of water, which gives them a thinner consistency. They are applied to the external skin with bare hands, a brush, a clean cloth, or cotton wool.
Ingredients or Materials
The key components of a skin care lotion, cream, or gel emulsion are the aqueous and oily phases, an emulsifier to prevent separation of these two phases, and, if used, the drug substance or substances. Various other ingredients such as fragrances, glycerol, petroleum jelly, dyes, preservatives, proteins, and stabilizing agents are commonly added to lotions. Some lotions contain ingredients that help to heal or treat specific skin issues. The following are some of the most common ingredients found in body lotions:
-
Emollients: These ingredients help maintain soft, smooth skin. Common emollients include petrolatum, lanolin, mineral oil, and dimethicone.
-
Humectants: These ingredients have a special power to draw in and retain moisture, making them essential in soaps and cleansers. Glycerine, glycols, and polyols are common humectants.
-
Occlusives: These ingredients form a barrier on the skins surface to prevent moisture loss. Common occlusives include dimethicone, lanolin oil, and tocopheryl acetate (Vitamin E).
-
pH Adjusters: These ingredients are used to adjust the pH of the lotion to match the skins natural pH. Sodium hydroxide is a common pH adjuster.
-
Preservatives: These ingredients are added to lotDefinition of Lotion
