We source our fragrances from trusted IFRA Certified Canadian Suppliers specializing in high quality ingredients for cosmetics, soaps, and candles. All of our fragrances are paraben and phthalate-free, as well as vegan.  Our general usage recommendations are 1-2% for lotions, 1-6% for soaps, and 5-10% for candles. IFRA Certificates are provided with each fragrance purchased.  For quality and safety for all of our customers, we do not accept returns on fragrances unless there was an error on our part.  We highly recommend you research your desired outcomes before attempting large batches in order to avoid wasting product. We offer 1 ounce samples for testing prior to ordering larger quantities.  Fragrances are measured by weight, which may cause variances in bottle volumes at time of packaging.
