We strongly recommend joining our Community Facebook group if you have Facebook!We have many soapers in the group who share with each other how fragrances behave in soap! Soap testing is ongoing, and results are listed on the fragrance listing on the website. Here is the link to find the fragrances with testing results:  https://midwestfragranceco.com/collections/frontpage/cp-soap-test-notes We also list these results in a document on the Facebook Community group. Here is the group link:  https://www.facebook.com/groups/midwestfragranceco/
