How to Calculate Ingredient Percentage in a Cosmetic Formula

Hello,

I understand you're new to this. Calculating proportions might seem complicated at first, but it's actually based on a simple principle.

To calculate the amount of an ingredient needed in a formula based on percentage (%), you can use the formula:

Weight of desired ingredient (grams) = (Desired percentage / 100) * Total weight of the entire formula (grams)

Example:

Suppose you want to make a soap bar with a total weight of 100 grams (which will include the soap base and other added ingredients).

• If you want to add Creamy Foamer at 5%:
  Weight of Creamy Foamer = (5 / 100) * 100 grams = 5 grams
  So, in a 100-gram formula, you need to weigh 5 grams of Creamy Foamer.

• If you want to add Creamy Foamer at 10%:
  Weight of Creamy Foamer = (10 / 100) * 100 grams = 10 grams
  So, in a 100-gram formula, you need to weigh 10 grams of Creamy Foamer.

Additional Example:

Suppose you want to make a soap bar with a total weight of 500 grams.

• If you want to add Creamy Foamer at 5%:
  Weight of Creamy Foamer = (5 / 100) * 500 grams = 25 grams
  So, in a 500-gram formula, you need to weigh 25 grams of Creamy Foamer.

• If you want to add Creamy Foamer at 10%:
  Weight of Creamy Foamer = (10 / 100) * 500 grams = 50 grams
  So, in a 500-gram formula, you need to weigh 50 grams of Creamy Foamer.

In summary:

You need to first decide the total weight of the soap bar you want to make (e.g., 100 grams, 500 grams, 1000 grams). Then, multiply that total weight by the percentage of the ingredient you want to add (by converting the percentage to a decimal first, e.g., 5% is 0.05, 10% is 0.10) to get the weight of that ingredient you need to weigh.

Try calculating based on the total weight you plan to make. If you have any more questions, feel free to ask!
