Fragrance Load Calculator
Pick a base, set the batch size, and get the ounces of base and fragrance oil. The defaults are the loads used in each recipe: room spray 4%, reed diffuser 20%, perfume 25%, laundry detergent 2%, mop soap 1.875%, all-purpose cleaner 3% of the concentrate, hand soap and body wash 0.5%.
The slider stays inside the range published for the base. The IFRA limit for your specific oil still applies.
Loads are a share of the finished product. Always confirm the IFRA limit for the specific fragrance oil and test for clarity and separation before a full run. The full table is on the fragrance oil load chart.
