Polyoxyethylene sorbitan fatty

An oral dental riase geaeraHy coasists of water, alcohol, a humectant, an emulsifier, flavor, color, and an active agent. Water is the primary vehicle. The alcohol provides bite and is also a formulation aid. The humectant improves the feel ia the mouth and also prevents locking of the cap to the container between uses glycerin or noncrystaUiziag sorbitol may be satisfactory. The emulsifier is a nonionic type, for example, a polyoxyethylene—polyoxypropylene block copolymer or a polyoxyethylene sorbitan fatty acid ester. Flavors are generally a type of mint or cinnamon. Colors are FD C or D C. 

Essentially, Tri-Act corrosion inhibitors are based on various combinations and ratios of different sorbitan fatty acid esters (e.g., sorbitan tristearate) and polyoxyethylene sorbitan fatty acid esters (e.g., POE... 

Polysorbates (polyoxyethylene sorbitan fatty acid esters, refer to Fig. 3) are a mixture of molecules of varying sizes rather than a uniform mixture of a single chemical entity. All four official polysorbates (numbers 20,40, 60, and 80), listed in U.S. Pharma-copeia/National Formulary (USP/NF), contain 20 moles of oxyethylene. Polysorbates...

Polyoxyethylene sorbitan fatty acid esters (polysorbates) are a series of partial fatty acid esters of sorbitol and its anhydrides copolymerized with approximately 20, 5, or 4 moles of ethylene oxide for each mole of sorbitol and its anhydrides. 

Non-silicone oUs are nonionic surfactants, which are polymers of castor oil, lanolinic acid and various kinds of alkylene oxide. These products are made by Daiichi Kogyo Seiyaku, Ltd. and are sold on the market under the trade names of Resinol F-140 and F-520 (6). Polyoxyethylene sorbitan fatty acid ester, such as the Tween series (Atlas Chemical Industries), can also be used.

Surfactants are used to control cell size and structure. The most common surfactants are siloxane-oxyalkylene copolymers, polyoxyethylene sorbitan fatty acid esters, and the condensation products of ethylene oxide with castor oil and alkyl phenols. A commonly added additive is urea which is used as a formaldehyde scavenger. Very fine particle size inorganic fillers can be added to act as nucleating sites and to promote finer, more uniform cell structure, as well as increased compressive strength, but at a cost of higher density.
