Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. More information about the EC Inventory can be found here. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. If generated, an InChI string will also be generated and made available for searching. More help available here. CAS no.

Therapeutically, simethicone is included in a number of oral pharmaceutical formulations as an antiflatulent, although its therapeutic benefit is questionable.

They can be manufactured as gels, resins, fluids, or elastomers, depending on the cross-linking characteristics. Toxicity testing using polydimethylsiloxane compounds on animals has found little, if any, harmful effects associated with chronic exposure. These tests include oral dosing and teratogenicity testing Cutler et al. Human health effects associated with silicone implants have been reported. Polydimethylsiloxane is the most prevalent silicone used medically and has been incorporated into many prostheses, including breast implants. Silicones are polymeric materials having silicon and oxygen on their composition. They are largely inert compounds usually heat-resistant, nonstick, and rubberlike.

Explore the versatility of Polydimethylsiloxane PDMS , its properties, applications, and environmental impact in our in-depth article. Polydimethylsiloxane, often abbreviated as PDMS, is a versatile and popular polymer used in a myriad of applications due to its unique properties. Primarily composed of silicon, oxygen, and carbon, this compound boasts remarkable flexibility and stability, making it a preferred choice in various industries. The basic structural unit of PDMS is a chain of — Si CH 3 2 -O- repeats, with silicon atoms linked by oxygen atoms — a structure that is essentially a silicon-oxygen backbone with methyl groups attached to the silicon.

CAS number. Contents move to sidebar hide. Silane precursors with more acid-forming groups and fewer methyl groups, such as methyltrichlorosilane , can be used to introduce branches or cross-links in the polymer chain. These "uncapped" amino- functional silicone compounds may be characterized by a linear or branched structure. Archived from the original on February 20, Other identifiers. Incompatibilities Simethicone as supplied is not generally compatible with aqueous systems and will float like an oil on a formulation unless it is first emulsified. However, substance notifications in the InfoCard are aggregated independently of the impurities and additives. ISSN More info on CLH can be found here.
