What is Silicone and Why is it Used in So Many Products?

What is Silicone and Why is it Used in So Many Products?

It seems like everywhere you look these days, you see “Silicone” is an ingredient or the entirety of a product you like or use.


Invented in 1943 and developed by Dow Corning, silicone was originally intended as an improved insulation grease for electrical machinery. Flash forward 70 years and silicone, a human-made synthetic rubber “polymer”, silicone can take many forms -- from liquid to high durometer or “hard” silicone. Silicone is present in sealants, lubricants, medicine, cosmetics, hair products, cookware, breast implants, space shuttle “o” rings, solar panels, airplane parts, fabric, boxes and bins, casting molds for soaps and candles, storage products…the list is seemingly endless. 


One of the most famous silicone products, Silly Putty, was invented by accident! In 1950, General Electric scientist James Wright was attempting to create an inexpensive substitute for synthetic rubber. When he mistakenly mixed boric acid with silicone, Silly Putty was born! Well, it actually took businessman Peter Hodgson to recognize its “fun” properties (bouncing, image transference, mold-ability), rename it “Silly Putty,” package it in a plastic egg (it was introduced at Easter time) and market it as a toy. Today, Silly Putty is owned by the Crayola Crayon company and is still sold in its original beige color but also in a rainbow of other colors.
