Emulsion Calculator

Emulsion Calculator is a handy tool used to determine the oil phase percentage in an emulsion. Whether you’re in the cosmetic industry formulating skincare products or in the culinary world creating unique dressings, knowing the oil phase percentage is crucial for achieving the desired consistency and properties in your emulsion.


The oil phase percentage in an emulsion is calculated using the following formula:

Oil Phase Percentage = (Volume of Oil / Total Volume) * 100

How to use

  1. Enter the volume of oil in milliliters (ml) in the designated field.
  2. Input the total volume of the emulsion in milliliters (ml).
  3. Click on the “Calculate” button to obtain the oil phase percentage.


Suppose you’re formulating a lotion and you have 50 ml of oil to be emulsified in a total volume of 200 ml.

Volume of Oil (ml): 50 Total Volume (ml): 200

Upon clicking “Calculate,” the oil phase percentage will be determined as follows:

Oil Phase Percentage (%) = (50 / 200) * 100 = 25%


  1. What is an emulsion? An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable). Typically, one liquid is dispersed in the form of small droplets throughout the other liquid.
  2. Why is knowing the oil phase percentage important? The oil phase percentage affects the consistency, stability, and performance of the emulsion. It determines the ratio of oil to other ingredients, influencing properties such as texture, viscosity, and appearance.
  3. Can the Emulsion Calculator be used for food recipes? Yes, the Emulsion Calculator can be utilized for both cosmetic and culinary applications where emulsions are involved.
  4. Is the oil phase percentage the only factor to consider in emulsion formulation? No, other factors such as emulsifier concentration, temperature, and mixing technique also play crucial roles in emulsion stability and performance.
  5. What if I don’t know the total volume of my emulsion? It’s essential to accurately measure or estimate the total volume to obtain precise results. Approximations may lead to inaccuracies in your formulation.
  6. Can I use this calculator for industrial-scale production? While the Emulsion Calculator is suitable for small-scale formulations, industrial-scale production may require more advanced tools and precise measurements.
  7. Does the calculator account for variations in oil density? No, the calculator assumes uniform density for the oil phase. It’s recommended to use oils with consistent densities for accurate results.
  8. Are there any safety precautions to consider when formulating emulsions? Yes, especially when dealing with potent ingredients or chemicals, it’s essential to follow safety guidelines, wear appropriate protective gear, and work in a well-ventilated area.
  9. What if my emulsion separates after formulation? Emulsion instability can occur due to various factors such as improper emulsification, incompatible ingredients, or inadequate stabilization. Troubleshoot by adjusting formulation parameters or using more effective emulsifiers.
  10. Can the Emulsion Calculator be used for water-in-oil emulsions? Yes, the calculator can be utilized for both oil-in-water and water-in-oil emulsions, as long as the appropriate phase volumes are entered.


The Emulsion Calculator simplifies the process of formulating emulsions by providing a quick and accurate way to determine the oil phase percentage. Whether you’re a novice experimenting in your kitchen or a professional developing cosmetic products, this tool empowers you to achieve consistent and desirable results in your emulsion formulations. By understanding the principles behind emulsion composition, you can create products with the desired texture, stability, and performance.
