How to Read Weight % of Cosmetic Recipes
The amount of ingredients in cosmetic recipes is always indicated as weight percentage rather than as weight like ounces, pounds, grams etc. or volumes like liquid ounces, cups, tablespoons or milliliters etc. This has two reasons: not everybody wants to make the same amount of a cosmetic product, and recipes are barely comparable and reproducible if they are calculated once in volumes and once in weights.
Weight percentages can be easily translated into weights. First determine the total weight of a product you would like to produce (e.g. 10 ounces). This amount equals 100 %. If now a certain ingredient is indicated with 5 weight %, you will have to add 5 % of 10 ounces of this ingredient (= 0.5 ounces). If your product is liquid you may prefer to translate the weight percentages into volumes. For example, if you want to make 1 cup of a product and an ingredient is indicated with 20 weight %, you will have to add 20 % of a cup (= 1/5 of a cup or 48 ml) of this ingredient. Please be aware that oils weigh less than water-like liquids. As a rule of thumb add about 10% more as compared to water-like liquids (in our example = 52.8 ml).
Conversion Chart (Weight % to Weights and Volumes)
This table converts weight percentages to weights and volumes for a product with a final weight of one ounce (= 28.4 g). For example: if 13 % of a certain ingredient is needed and you want to make a total of one ounce of the final product, you have to add either 0.13 oz, 3.7 g, 0.25 tablespoon, 0.74 teaspoon or 3.7 ml of this ingredient. If you want to make 8 oz of this product you would have to add 8 times the amount mentioned above.
