Dimethicone or glycerin as it is commonly known is a kind of non-reactive silicone, a unique organic polymer which is isolated from sugar cane and other plants. Dimethicone was first developed gradually as researchers started to find out the ways in which silicon bonds with different elements. The best example of this is when two silicon atoms bind with each other, this is what we know as silicon. This kind of bonding produces dimethyl form of a silicone oil, which is widely used in a number of applications.
Dimethicone and glycerin are two completely different things and both have their own benefits. Dimethyl glycerin has many of the same properties as glycerin but does not have as much of a sticky property as glycerin. It has an even more oily feel and is usually used for use on food packaging. Dimethyl silicone is very strong and is not easily affected by heat, it does not degrade even if left out to dry. It also comes with anti-foaming properties and can be easily molded into the right shape with just a few strokes.
Dimethyl silicone and glycerin both have their own disadvantages, Glycerin has a tendency to stick to its own surface which makes it difficult to use and can result in unwanted particles stuck to its surface. Dimethyl silicone tends to cause some staining on the surface and can therefore make it hard to remove. On the contrary, glycerin is soluble and easily soluble to most solvents. Glycerin is also used as a food additive to make ice cream and sherbet and can help preserve freshness of the ice cream.
