Cosmetic Formulating Blog Series | Building the Formula

In our last blog post on Cosmetic Formulating we went over some formulating basics, including what a formula is, whether it will be organic, natural and/or cruelty-free, understanding measurements and synergy of your ingredients. In this blog we will go over how you build the formula.

Factors to Consider

Prior to making your formula, you must consider many factors and get clarity on what kind of product you want to make. Ask yourself the following questions:

  • Who is the consumer for this product? Age, gender, skin type, etc.?
  • What properties do you want in the product? Example- moisturizing, protecting, vitamins, etc.
  • What kind of container are you going to use?
  • How will the product be applied?
  • What color will the formula be once all the ingredients are in?
  • How much will the product cost?
  • What shelf-life will the product have?


To build your formula, you will need to use simple math to create a formulation key. The easiest way is to utilize percentages. Your total formulation will amount to 100%. Then each ingredient will be a percentage of 100. This way you can increase or decrease your amount easily by utilizing the percentage to determine the amounts in grams or ounces of your ingredients. The ingredients in your product will fall into the following categories: water, oil, emulsifiers, and additives. Depending on what kind of product you’re making, each category will have a different percentage range. Experiment with different amounts of each ingredient until you get the end-product you want. This will now be your formulation!
