Have you ever started to make a batch of soap and realized you didn’t know how much fragrance or essential oil to use? When I first started soaping, trying to figure out how much scent to add to a batch was a bit of a experimental process, and it didn’t always turn out so well. Over or under-fragrancing is frustrating if you add too much of an expensive essential oil or not enough fragrance and end up with a beautiful, albeit unscented, bar of soap. Knowing how much fragrance or essential oil to add can save you both time and money!
Things have come a long way since my fragrance guesswork, and one of the best features on the Bramble Berry site is the Fragrance Calculator. It’s a handy tool that takes the guess work out of soaping and gives you complete control over your recipes. Read on to learn how to make the Fragrance Calculator for you.
We’re continually updating our fragrance calculator, so if you don’t see the fragrance or essential oil you’d like to use, let us know in the comments! In the meantime, you can use the information on general recommended usage rates at the bottom of this post to fragrance your products.
ONE: Click on this link to get to Bramble Berry’s Fragrance Calculator. You can also find it on the bottom of Bramble Berry homepage on the left side. The calculator works for a variety of products, including lotions, liquid soaps, cold process and melt & pour soaps, salts & bath fizzies, rebatch, candles and even your homemade shampoo and conditioner.
TWO: To use the calculator, enter the total amount of product you are making in grams or ounces and select the fragrance or essential oil from the list below. When making cold process soap, this means the total weight of your soap, including oils, liquid and lye. For the sake of this tutorial, I’ve chosen to “make” 16 oz. of cold process soap.
THREE: Now it is time to choose your fragrance or essential oil. Today I’ve gone with our sample of the month, Chai Tea Cybilla (have you gotten your package yet? Make sure to check out our Make It Month: #BrambleChai contest). Once you’ve selected the fragrance or essential oil, the calculator will take you straight to the results.
FOUR: In the Fragrance Calculator Results section, it will give you the recommendations for a light, medium or strong scent in ounces (by weight — see why weight is the best way to go in this blog post), grams, teaspoon, tablespoons and even milliliters. The ‘Notes’ section will describe the fragrance and include information about any discoloration or acceleration as well as the flashpoint and other product notes. You can print from this page so you have all the information in front of you.
Finding out how much fragrance or essential oil you need to use is really that simple. If you find that you fragrance or essential oil isn’t listed on Bramble Berry Fragrance Calculator (we do try to update it as often as possible), let us know and we will add it as soon as we can. You can also follow the recommended amounts for both essential oils and fragrance oils for various products below.
Cold Process Soap: .7 ounces per pound
Melt & Pour Soap: .25 ounces per pound
Rebatch Soap: .3 ounces per pound
Lotions: .2 ounces per pound
Liquid Soap: .3 ounces per pound
Salts & Scrubs: .3 ounces per pound
Candles: .5 ounces per pound
Shampoo & Conditioners: .2 ounces per pound
Cold Process Soap: .7 ounces per pound
Melt & Pour Soap: .5 ounces per pound
Rebatch Soap: .6 ounces per pound
Lotions: .3 ounces per pound
Liquid Soap: .6 ounces per pound
Salts & Scrubs: .2 ounces per pound
Candles: 1 ounce per pound
Shampoo & Conditioners: .4 ounces per pound
Of course, some fragrances and essential oils are exceedingly strong — or sadly wimpy — in soap, and so you can always use a little more or a little less to your preference. After all, if you’re using English Rose and you know it’s a strong fragrance oil (it is!), it would be a waste of money to use a full .7 ounces per pound of soap. Always adjust to your personal nose and fragrance preference.
