Emulsifying agents polysorbate

Sorbitan monostearate is used as an emulsifying agent in cake mixes, icings, baked goods, puddings, imitation whipped cream, hemorrhoid creams, and creams to treat dry skin. It is often used with polysorbate 80. 

Polysorbate 80 is an emulsifying agent that is often used in ice cream to prevent milk proteins from completely coating the fat droplets. This allows them to join together in chains and nets, to hold air in the mixture, and to provide a firmer texture that holds its shape as the ice cream melts. 

Surfactant Substance that adsorbs to surfaces or interfaces to reduce surface or interfacial tension may be used as wetting agent, detergent, or emulsifying agents Benzalkonium chloride, nonoxynol 10, oxtoxynol 9, polysorbate 80, sodium lauryl sulfate, sorbitan monopalmitate... 

Buffers can also be provided in parenteral formulations to ensure the required pH needed for solubility and/or stability considerations. Other excipients included in parenteral products are preservatives (e.g., benzyl alcohol, p-hydroxybenzoate esters, and phenol), antioxidants (e.g., ascorbic acid, sodium bisulfite, sodium metabisulfite, cysteine, and butyl hydroxy anisole), surfactants (e.g., polyoxyethylene sorbitan monooleate), and emulsifying agents (e.g., polysorbates). An inert gas (such as nitrogen) can also be used to enhance drug stability. Stability and solubility can also be enhanced by the addition of complexation and chelating agents such as the ethylenediaminetetraacetic acid salts. For a more detailed list of approved excipients in parenteral products, the reader should consult the monographs within the USP. 

To act as solubilizing, wetting, or emulsifying agents such as Cremophor EL, sodium desoxy-cholate, Polysorbate 20 or 80, PEG 40 castor oil, PEG 60 castor oil, sodium dodecyl sulfate, lecithin, or egg yolk phospholipid. 

Commercial products are complex mixtures of partial esters of sorbitol and its mono- and di-anhydrides condensed with an approximate number of moles of ethylene oxide. The formula of a representative component is shown above. The polysorbates are miscible with water, as reflected in their higher HLB values (see Table 1.2), and are used as emulsifying agents for oil-in-water emulsions.

Sorbitan fatty acid esters are produced by polymerization of ethylene oxide to sorbitan fatty acid esters. The resulting polyoxyethylene sorbitan esters are nonionic hydrophilic emulsifiers. They are used in bakery products as antistaling agents. They ate known as polysorbates with a number as indication of the type of fatty acid used (e.g., lauric, stearic, or oleic acid). 

Polysorbate 80 Commercially known as Tween 80, polysorbate 80 is used in the food industry as an emulsifier (basically, a thickening agent). It is created from sorbitol (an acidic sugar alcohol) and oleic acid (which is a healthy fatty acid when it is not chemically altered and combined with other ingredients). 

The oil phase preferably includes mineral oil, petrolatum, cetyl alcohol, or stearyl alcohol. Emulsifiers such as polysorbate 80, sorbitan monostearate, or others known in the art may be used. Buffering agents, antioxidants, and chelating agents may be added to improve the characteristics of the formulation. 

Cream 0.05%, ointment 0.05%, and lotion 0.05% contain desonide (Pregna-1,4-diene-3,20-dione, 11,21 -dihydroxy-16, 17-[(l-methylethylidene)bis(oxy)]-,[ll(beta),16(alpha)-]), a synthetic nonfluorinated corticosteroid, for topical dermatologic use. The corticosteroids constitute a class of primarily synthetic steroids used topically as anti-inflammatory and antipruritic agents. Each gram of cream contains 0.5 mg of desonide in a base of purified water, emulsifying wax, propylene glycol, stearic acid, isopropyl palmitate, synthetic beeswax, polysorbate 60, potassium sorbate,...
