What is Polydimethylsiloxane?

Polydimethylsiloxane (PDMS) is a polymer all-natural silicon substance, typically called silicone. Optically clear with 100% light passage. Therefore, polydimethylsiloxane itself is clear, yet it is usually emulsified and marketed in a cream state when used.

Polydimethylsiloxane Property

Boiling point 182 °C
density 0.98 g/mL at 25 °C
refractive index n20/D 1.406
Fp 155 °F

Polydimethylsiloxane Uses

Polydimethylsiloxane has a thicker structure, so it is typically used in mix with lighter-textured silicone oils (such as cyclopentasiloxane) to much better supply it to the hair and skin, particularly in hair conditioning products. Normally, this item can additionally be made use of in items such as face cream, mascara, shampoo/conditioner, styling gel and structure.

Whether the shampoo included with Polydimethylsiloxane is clear or otherwise has nothing to do with the type of polydimethylsiloxane. It primarily depends upon the aggravating treatment and system kind. If it is an emulsified system, it is generally nontransparent. If no pigment is added, it will definitely be white. Consisting of pigments lead to equivalent shades.+
