“A home fragrance is first and foremost a good smell. It doesn’t have to mingle with the skin. Furthermore, it doesn’t have to last and evolve in the same way. Home fragrances are more one dimensional. The most technical aspect of working on a home fragrance is to develop a perfume that marries itself well with the supporting base, for instance the wax.
In other words, when working on a home fragrance one just concentrates on beauty and on comfort which is simpler than doing a perfume. However, evaluating candles or perfume guns is a tedious and long process. You can only smell one at a time (or one per room), rather than smelling four of them on your arms!” -Perfumer Frédéric Malle
