Enter the volume of oil and the total volume of the emulsion into the calculator to determine the oil phase percentage. This calculator can also evaluate any of the variables given the others are known.

## Emulsion Formula

The following formula is used to calculate the oil phase percentage in an emulsion.

OP = (V_oil / V_total) * 100

Variables:

- OP% is the oil phase percentage (%) V_oil is the volume of oil in the emulsion (ml) V_total is the total volume of the emulsion (ml)

To calculate the oil phase percentage in an emulsion, divide the volume of oil by the total volume of the emulsion. Multiply the result by 100 to convert the fraction to a percentage.

## What is Emulsion?

An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) due to the presence of an emulsifying agent. This agent, often a type of surfactant, reduces the surface tension between the liquids, allowing them to blend together. Emulsions are commonly found in various areas such as food, cosmetics, pharmaceuticals, and paints, with examples including milk (an emulsion of water and fat) and mayonnaise (an emulsion of oil in water).

## How to Calculate Emulsion?

The following steps outline how to calculate the Oil Phase Percentage (OP%).

- First, determine the volume of oil in the emulsion (V_oil) in milliliters (ml).
- Next, determine the total volume of the emulsion (V_total) in milliliters (ml).
- Next, use the formula OP% = (V_oil / V_total) * 100 to calculate the Oil Phase Percentage.
- Finally, calculate the OP%.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

Volume of oil in the emulsion (V_oil) = 50 ml

Total volume of the emulsion (V_total) = 200 ml
