Base Powders

updated 09/23/2017

This page is just me making my personal notes public, but I’m open to suggestions and ideas to make it better and more accurate.  Feel free to ask questions or leave critique.

I’ve divided the different properties desired in base formulas into groups – in the left column is the ingredient name, the right column is formulation suggestions I’ve gathered and had luck with along with other notes.

This page will be updated as needed and is made with eyeshadows, highlighters, and pressed foundations in mind.

A useful cheat to formulating base powders is to think of the percentages as slices in a pie chart.  I personally like to use an interactive pie chart online to help me figure out what I need.  Click here for the website I use.
