Use in almost all my CP Soaps now
Thank you for carrying this product! I've been incorporating this into almost all my cold process soap formulations for almost a year now. The drops mix easily into my oils (before adding my lye water). I also greatly appreciate the information Make Your Own Buzz supplies about usage rate recommendations; thank you for providing this for us! While I do not have any side-by-side comparisions of older soap made with and without the extract, I have not seen any of my batches with the ROE develop DOS. The only improvement that I recommend...is making the cap a dropper cap!
