You cannot provide “A wonderful” scent to a product without adding fragrances in some form.
While you can technically add some essential oils and not write “Fragrance” on the ingredients list (Instead, you would be adding each essential oil as an ingredient), it would be somewhat deceptive and calling it “Fragrance-free” would be an outright lie.
Remember essential oils contains a buck-ton of allergens, and depending on the geographical location you may be required to disclose some of them if they are in sufficient amounts.
A perfume house would do a much better job, if you want a scent, just write fragrance and be done with it. But considering the holidays, here is an example for one combination I quite like.
40% Citrus Aurantium Dulcis (Sweet Orange) Peel Oil
20% Pinus Sylvestris (Scotch Pine) Leaf Oil
20% Citrus Paradisi (Grapefruit) Peel Oil
5% Myristica Fragrans (Nutmeg) Fruit Oil
2.5% Cinnamomum Cassia (Cinnamon) Leaf Oil
2.5% Syzygium aromaticum (Clove) Fruit Oil
10% Vanillin
Use the combination as fragrancing raw-material, NOT on its own - and there are allergens to disclose.
As for stability over time, it won’t hold up (Vanillin is a cruel mistress). It will also discolour your product when added.
Happy holidays.
