What is dimethicone formula?


What is polydimethylsiloxane used for?

Low–molecular weight PDMS is a liquid used in lubricants, antifoaming agents, and hydraulic fluids. Its use in breast implants is not as popular as it once was because of safety concerns. At higher molecular weights, PDMS is a soft, compliant rubber or resin. It is used in caulks, sealants, an even Silly Putty.

Is PDMS amorphous?

For amorphous PDMS, the modulus increases between −100 and −90 °C, and then reaches the modulus value of the semi-crystalline sample. A second important decrease of the modulus (and a single tan δ peak) is then obtained between −70 °C and −40 °C that can be attributed to the melting of PDMS crystals.

What is the molecular formula for dimethicone silicone?

INCI name: dimethicone. Synonyms: poly(dimethylsiloxane) Molecular formula: (C2H6OSi)nC4H12Si. Molecular weight: variable. IUPAC name: poly(dimethylsiloxane) CAS number: 63148-62-9. Silicones are manufactured from quartz, which contains silicon in the form of SiO2.

How does the molecular weight of dimethicone affect its properties?

Dimethicone is a polymer. Therefore, many of its properties will depend on its molecular weight. Table 1: Various grades of dimethicone available in different molecular weights ( characterized by viscosity) and the corresponding specific gravity and refractive index values.

What kind of products can you use dimethicone in?

Dimethicone is one of the most widely used ingredients in both cosmetics and personal use products as well as a food additive in cooking oils and kids’ toys. In 2019, the US Food and Drug Administration recorded 12,934 dimethicone containing products.
