Fragrance Check FAQ
Does Fragrance Check Cost Anything?
No. Fragrance Check is free. You can check up to 5 fragrances at a time, and up to 10 checks a day.
Can I Check Fragrances From Other Shops?
Yes, fragrance oils and essential oils from any shop. Paste a link, or type the name and brand. If a fragrance will be tricky, we'll suggest one of ours that behaves.
What Is Acceleration?
Some fragrances make soap batter thicken fast, so you have less time to pour and swirl. In the worst case it seizes in the pot. Soaping cooler and stirring the fragrance in by hand at light trace helps. Read more in Why Did My Soap Seize or Thicken So Fast?
Why Do Some Fragrances Turn Soap Brown?
Vanillin, found in vanilla, bakery, gourmand, amber and many floral scents, slowly turns soap tan to dark brown over days and weeks. The more vanillin, the darker it gets. Read more in Why Did My Soap Turn Brown?
How Much Fragrance Should I Use?
In cold process, most soapers use around 5% of their oil weight; go as low as 3% for a light scent, or up to 6% for a strong one. Melt and pour uses less, 1% to 3% of the soap base. Never go over the fragrance's IFRA limit for soap, and always weigh it. Our Fragrance Calculator does the math, and How Much Fragrance Oil Should I Use in Soap? explains the rates.
