FAQ
Do I need to complete The Practical Preservation Masterclass to use The Practical Preservation Brain?
No, but they are designed to be a great pair.
The Practical Preservation Brain comes with its own tutorial so you know how to use it, but it doesn’t teach you how to understand, choose, use, test, and formulate with preservatives. That’s what The Practical Preservation Masterclass does!
Without completing The Practical Preservation Masterclass, many of the suggestions in The Practical Preservation Brain won’t make much sense unless you’ve been formulating for quite a long time and have done lots of your own research into and work with preservatives.
Are the preservatives in The Practical Preservation Brain natural?
Over half of the preservatives profiled in The Practical Preservation Brain are natural.
What software does The Practical Preservation Brain use?
The Practical Preservation Brain is a Google Sheet. Google Sheets is a free spreadsheet software (similar to Excel and Numbers); if you have a google account (like a gmail address), you already have a Google Sheets account.
You can download the spreadsheet file and try it in Excel or Numbers, but I have not tested it in either software and cannot guarantee it will work the same way.
Can I get a refund?
No; due to the nature of digital downloads, this product is final sale.
