Help with percentages
Hello, I am making a face cream and need help figuring the percentages. I will be using a pre-made lotion base and I will be adding Niacinamide, Glucosamine, and Panthenol powders.
My container holds 1.5 fluid ounces and I want the cream to be 5% Niacinamide, 3% Glucosamine, and 2% Panthenol. Will someone please show me the formula to use to figure out how much of the 3 powders I need to add to my 1.5 fluid ounces of lotion to achieve those percentages? Thank you! -

N: 45g x 0.055
G: 45g x 0.033
P: 45g x 0.022
near enough. -
that’s way to high of percentages. why not knock those down a tenth of a percent and make some money?

Thank you Belassi! I appreciate it! I thought about it after I asked the question and realized that I could just weigh my 1.5 fluid ounces of lotion and then I could have figured it out precisely, but I will go with your numbers as it’s less of a pain in the rear, and definitely close enough.
Chickenskin, as for now this is just for my personal use so I am actually saving money by making my own skincare products and not paying ridiculous prices. But if I ever do sell them I will for sure bring the percentages down. I am an esthetician so I do actually plan on selling my own products one day. For now I am my own guinea pig. Haha!

If you’re going to do this for any length of time, it will be incredibly useful for you to understand how to work with percentages yourself. Excel or its free alternatives are a wonderful tool to assist with this.
