You might be focusing on the word oil more than silicone but on the macro level, this might not feel like true oil so sometimes it is also referred to as silicone fluid. These are interchangeable terms.
Most commonly used silicone oils are polymers of silicone where there is oxygen on alternative positions. This linear chain is maintained in a spiral position which makes it easy for the molecule to move over each other and this gives it an oily look. Silicone oils are stable to degradation by high temperatures. The main form which exists is Poly Dimethyl siloxane. Like this polymer form, other organic groups such as phenyl, vinyl amino acid, and epoxide can also be added to siloxane groups to create polymers that have different characteristics than their counterparts or other polymers.
Structure of Silicone Oil:
Silicone oil has a backbone of silicon and oxygen which are placed in alternative positions. Silicone present on these alternating positions in the linear chain also carries two carbon groups methyl, phenyl, and other amino acid groups. Different groups bring a different kinds of characteristics and reactivity.
If we add different organic groups to these Silicone atoms, we can attain silicone oils that can be integrated into two different compounds at the same time.

How to Use Silicone oils in acrylic paints?
The beauty of acrylic pouring increases with the number of cells being created primarily by the difference in the density of both paints. Silicone oil is the basic component in creating these cells.
Let’s discuss the step-by-step process of how to create cells in an acrylic painting using silicone oil.
Identifying the right Acrylic Paint:
There are two types of acrylic paints, those which do not need additional water and therefore their viscosity can’t be changed and those which require the addition of water, and their viscosities are dependent upon the amount of water added in them.
After selecting what kind of acrylic paint, you are going to use put both these in two separate jars.
Selection of the Pouring Medium:
Pouring medium adds flow and smooth texture to the acrylic paints being used in painting. Pouring medium helps to maintain the viscosity and dilute the paints at the same time.
Add the pouring medium to both of the above-mentioned jars and then mix the pouring medium with acrylic paints separately, note that the amount of pouring medium should be slightly more than the number of acrylic paints.
Addition of Silicone Oil:
After mixing the pouring medium and paint, add 2 drops of silicone oil for 10 ml of acrylic paint and let the mixture blend by slightly moving the mixer stick.
Pouring and Heating:
You are not going to let the acrylic paints sit idle in the jar, it must be poured onto a flat surface such as a paper canvas or any other flat surface, and make sure to cover all of the space on the canvas.
After pouring the paint mixture on the surface, we should dry the paint using a heat gun. As soon as heat is applied, the cells will start to pop up in the painting and you’ll get the desired results.
Usage of Silicone Oil in Agricultural adjuvants
Silicone oil is used in agricultural sprays containing pesticides, herbicides, insecticides, and fungicides and it helps these to perform better (synergistic effect)
How does silicone oil act as a synergist to agricultural sprays?
For a chemical spray to be more effective and efficient, it needs to cover the surface of the plant better but that is not easy for these pesticides or herbicides as there is a difference in surface tensions between the plant and spray droplets.
Nearly 99% percent of the spray will not reach its target if used without adjuvants. To counter this problem, silicone oil comes into play. The maximum leaf surface can only be covered only when the surface tension problem is solved.
Higher surface tension means the spray droplets are in lesser contact with the surface of the leaf, on the other hand, lower surface tension means flatter droplets and better coverage of leaf surface area.
As silicone oil possesses lower surface tension and is chemically stable, the addition of Silicone oil will collectively lower the surface tension of agricultural sprays and increase its availability, and enhance efficiency.
