Polydimethylsiloxane (PDMS): A Member of Polymeric Organosilicon Compounds Used In Various Industries Due To Its Versatility and Properties

Polydimethylsiloxane (PDMS) is a compound that is commonly used for the development of contact lenses, but it has many other uses as well. Surfactants and foaming agents are among the many things that are made from PDMS. Other uses include, the treatment of petroleum jelly and rubber. The chemicals used in the manufacture of cosmetics and medicines may also be derived from PDMS. The production facilities for PDMS in Europe are located in France, Germany and the U.K. In Germany, PDMS is classified as “slightly water polluting”.

It was not that long ago that scientists thought there might be some connection between the use of polydimethylsiloxane in cosmetics and the development of allergic reactions. Scientists have since conducted studies and discovered that there actually are connections between the use of this chemical agent and the development of eczema and allergic reactions. The link between cosmetics and skin irritation and allergy is a result of the fact that the ingredients in these products can change the properties of the skin. The change in the material allows the introduction of irritating substances such as fragrance, colorants, preservatives and emulsifiers. The use of poly dimethylsiloxane also changes the physical structure of the cells.

Polydimethylsiloxane (PDMS) is not only used for the manufacture of the liposome but also for other cosmetic products such as dentures, wigs and the like. It has been successfully used as an embosser for implants and it also produces a fine texture on the surface of the silicone hydrogel. The texture gives the impression that the liposome is a gel and allows the dentist to sculpt the shape of the lips and the other components of the oral prosthesis. The silicone hydrogel is also effective in treating cavities and has proven to be useful for filling surgical wounds. 

A number of industries use polydimethylsiloxane for lubrication of hydraulic parts and for preventing friction on components during transportation. The material has proven effective in preventing corrosion of a variety of metals used in the manufacture of mechanical parts. In addition, it has been used to prevent the formation of heat-resistant alloy wheels used in vehicles. In general, the material exhibits good biological support and exhibits high resistance to chemicals, enzymes and temperature.

The major advantage polydimethylsiloxane has over silicone-based products is its longevity. The material has a maximum life of about 150 days, when it is exposed to high temperatures. This duration is also dependent on how it is used; for example, higher concentrations tend to have longer service life than lower concentrations. Also, silicone gel based products will eventually become inert when exposed to heat. Unlike these synthetic alternatives, however, polydimethylsiloxane does not deteriorate in both temperature and environment.
