Topical cream formulations consist of the oily phase and water phase. As the two phases are immiscible, in the absence of thickeners and emulsifying agents, molecules in the topical cream formulation will form droplets. Rapid aggregation of droplets within each phase will eventually lead to phase separation. Physical stability is determined by ...
Emulsifying agents are effective at extinguishing fires on small, thin-layer spills of flammable liquids (class B fires). Such agents encapsulate the fuel in a fuel-water emulsion, thereby trapping the flammable vapors in the water phase. This emulsion is achieved by applying an aqueous surfactant solution to the fuel through a high-pressure ...
GMS is a food additive used as a thickening, emulsifying, anticaking, and preservative agent; an emulsifying agent for oils, waxes, and solvents; a protective coating for hygroscopic powders; a solidifier and control release agent in pharmaceuticals; and a resin lubricant. It is also used in cosmetics and hair-care products.
It is used as a solubilizer and emulsifying agent in foods, cosmetics, and pharmaceuticals, often as an ointment base. [1] It is used as an oil in water (O/W) emulsifier for creams/lotions, and a wetting agent .
Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone .

Sorbitan is a mixture of isomeric organic compounds derived from the dehydration of sorbitol and is an intermediate in the conversion of sorbitol to isosorbide. [1] Sorbitan is primarily used in the production of surfactants such as polysorbates; which are important emulsifying agents, with a total annual demand of more than 10,000 tons in 2012. [2]
It is added to mortar dry mixes to improve the mortar's properties such as workability, open and adjustment time, water retention, viscosity, adhesion to surfaces etc. Construction grade methyl cellulose is not to be identified with food and pharmaceutical grade methyl cellulose and hydroxypropyl methyl cellulose, as it may be cross-linked with ...
Cream. A cream is a preparation usually for application to the skin.Creams for application to mucous membranes such as those of the rectum or vagina are also used. Creams may be considered pharmaceutical products, since even cosmetic creams are manufactured using techniques developed by pharmacy and unmedicated creams are highly used in a variety of skin conditions (dermatoses).
