![]() ![]() Viscose, which cannot be washed from the skin easily with water and is more viscous than oil What separates oil in water emulsions (O/W) from water in oil emulsions (W/O):Įmulsions of O/W are continuous emulsions whereas emulsions of oil and water are dispersed emulsionsĮasily washable from the skin due to its lower viscosity Milk has fat in it, Butter has oil in it, Liquid paraffin has paraffin in it, etc.ĬlassificationEmulsions can be classified into three categories: On the one hand, there is the dispersed phase while on the other hand, there is the continuous phase.Įxamples - Emulsions are substances that contain fats and liquids. Hydrophilic surfactants dissolve in water and act as emulsifying agents for O/W whereas lipophilic (or hydrophobic) surfactants dissolve in the oil and act as emulsifying agents for W/O. Water- and fat-soluble surfactants are classified as hydrophilic or lipophilic based on their moisture capacity. What type of emulsion is created depends on what emulsifier was used. Water-in-oil (W/O) emulsions are dispersed phases consisting of oil and continuous phases consisting of water, or oil in water (O/W) emulsions, which have reversed dispersion and continuous phases. Oil and water are emulsified when mixed with an emulsifier, for instance, a protein, phospholipid, or nanoparticle, which can bind to immiscible liquids. The term Emulsion is used in chemistry to refer to a mixture of two or more liquids in which droplets of microscopic or ultramicroscopic size are distributed throughout one of the liquids. When two or more liquids are emulsified as droplets, they become miscible when together, but the dispersion is accomplished with emulsifying agents. Emulsion DefinitionEmulsions are biphasic liquid dosage forms that are separated into two components.
