Does Sugar Dissolve in Oil?
You very likely know sugar dissolves in water until it reaches saturation. But you’re probably wondering if sugar dissolves in oil as it does in water.
The answer is Yes. Sugar generally dissolves in oil but not in all types of oils. And here is why.

Sugar has a ring structure made up of carbon, hydrogen, and oxygen. It contains chemical groups that can connect with the CHs of lipids as well as chemical groups (OH) that can react with water molecules.
When sugar is added to oil, sugar molecules bind to the lipids. They gradually fade into the background until they are entirely undetectable as granules. Owing to these qualities, sugar typically dissolves oil.
However, sugar does not dissolve in all oils because every oil is made up of different lipid chemical chains.
These different components may not have the chemical affinity to react with sugar molecules.
Which types of oils does sugar dissolve in?
Sugar usually dissolves in most vegetable oils like corn oil, canola oil, and olive oil. However, it will not dissolve in fatty fish oils or animal fat like lard or butterfat.
These fats are more saturated, and their chemical character is not as flexible as that of vegetable oils.
Unfortunately, we aren’t going to be able to provide you with a definitive list of oils that sugar dissolves in and those that it doesn’t.
This is because the solubility of sugar mainly depends on the chemical structure of the lipid chains.
The only way to figure out if sugar is going to dissolve in a specific oil is to conduct your own tests.
How to improve your chances of sugar dissolving in oil?
You can improve your chances of dissolving sugar in oil using some simple techniques.
Use fine sugar
The finer the granules, the easier it is for sugar to dissolve in oil. Use powdered sugar instead of granulated sugar to increase your chances of dissolving sugar in oil.
Increase oil temperature
If you increase the temperature of the oil before mixing, sugar dissolves easier. This is because oil particles have more kinetic energy, enabling them to mix more easily with sugar.
Use chemical agents
If your oil of choice is one that sugar doesn’t dissolve in easily, you can try adding some chemical agents.
Adding acetone or thinner increases the oil’s polarity, making it compatible with sugar.
Please note these are toxic chemicals and pose a health risk if consumed in any quantities. Therefore, these agents should only be used if the oil you want to dissolve them in is non-edible.
Does dissolving sugar in water before mixing it with oil help?
Yes. Dissolving sugar in water prior to adding it to oil is an excellent technique for increasing your chance of dissolving sugar.
However, this will create a water-in-oil emulsion and may not be the best choice in some cases.
Why does sugar dissolve in oil while salt does not?
Sugar molecules contain polar chemical groups that can bind to lipids. Salt, on the other hand, only contains atoms with positive charges (Na+) and negative charges (Cl-) without any polar groups.
This makes it difficult for salt to dissolve in oil because it cannot bond with the lipid chains of oil.
What happens to sugar that isn’t dissolved in oil?
Sugar that is not dissolved in oil simply settles on the bottom of a cup. Because sugar has a higher specific density, it sinks to the bottom of the liquid.
Does sugar dissolve in oil and thicken the oil?
Sugar dissolves in oil but does not necessarily thicken it. Sugar contains both the hydrophilic (water-loving) OH chemical groups as well as lipophilic (oil-loving) CHs.
This enables sugar molecules to bind with lipid chains on one end and water molecules on the other end. However, this doesn’t necessarily result in an oil-thickening effect.
Does sugar dissolve in oil and water with the same efficiency?
No, sugar dissolves in water faster and more efficiently than it does in oil. This is because sugar has more hydrophilic OH chemical groups than lipophilic CHs.
This means sugar’s affinity to bind with water molecules is higher, making it dissolve in water more readily.
Does sugar mix in oil separate over time?
Sugar that is not completely dissolved in oil will settle over time. Also, as the environmental conditions change (temperature, pressure, etc.), dissolved sugar may separate from the oil.
This is especially true if the mixture has been heated and then allowed to cool down.
Does sugar dissolve in heated oil?
Sugar does dissolve better in oil that has been heated. This is because sugar dissolves more easily when the interfacial tension between the sugar and water drops to its lowest point, which occurs when oil is at its highest temperature.
Does sugar dissolve in oil change its viscosity?
Although sugar dissolves in oil will increase the specific density of the oil, it doesn’t make an important effect on the viscosity of the oil.
However, if you try to dissolve higher levels of sugar in oil using industrial production techniques you may end up changing the viscosity of the oil.
Does white sugar and brown sugar dissolve similarly in oil?
White sugar and brown sugar dissolve similarly in oil. Brown sugar is white sugar that has been mixed with molasses, which doesn’t make it dissolve better or worse than white sugar in oil.
Does caramelizing sugar make a change in sugar solubility in oil?
Yes, caramelizing sugar can make an important change in the solubility of sugar in oil.
Because caramelization changes the chemical structure of sugar creating a new product with unique properties. The new product may dissolve faster or slower in oil than the original sugar.
Does honey dissolve better in oil than table sugar?
Honey and table sugar (sucrose) contain similar chemical structures with the primary difference being glucose versus fructose. Thus, honey and table sugar dissolve similarly in oil.
