Common questions

How much fragrance oil should I use in soap?

Follow the supplier's maximum usage rate, often around 3-6% of oil weight. More is not always stronger and can irritate skin.

Why does essential oil scent fade in soap?

Many essential oils evaporate during saponification and curing. Blending with longer-lasting base notes helps anchor scent.
