I purchased the Incense scent essential oil. Haven't used this in my aroma diffuser yet but just sniffing the bottle it smells WONDERFUL! Like OMG stagger back good. If you are tired of buying multiple essential oils to create your own blends then this brand may be what you are looking for as all of the scents in this line are essential oil blends. I do not detect any weird artificial chemical smell in the Incense Essential Oil. It smells very smooth, strong and natural reminding me of most common stick incense. The bottles says PREMIUM ESSENTIAL OIL and there is no mention of fragrance oil. Comes in a nice giftable box and the bottle was sealed nicely with no leakage.Do not go by the Saphrius scent descriptions here on Amazon as some of them are wrong. For instance, the Incense scent is described as having a fresh scent of eucalyptus even though there is no eucalyptus oil in it nor does it smell like eucalyptus at all. You are better off purchasing based on the name of the scent as that seems to be more accurate. Below I have posted some the CORRECT scent notes for different varieties straight from the Saphirus brand website in hopes it will help others. I will add more when I have time.Cinnamon - Top Notes: Cinnamon Leaves, Pepper - Heart Notes: Red berries, Cinnamon Berry, Licorice - Base Notes: BenzoinAmber - Top Notes: Honey, Haka Tonka - Heart Notes: Vanilla, Bulgarian Rose - Base Notes: Patchouli, Woods, White MuskNew Delhi - Top Notes: Lily of the Valley, Violets, Roses, Jasmine - Heart Notes: Vetiver, Floral Bouquet - Base Notes: Vanillas, Patchouli, Woody Notes, MuskVrindavan - Top Notes: Roses, Violets, Bergamot - Heart Notes: Floral Bouquet, Sweet Notes - Base Notes: Vetiver, Musk, Cedarwood, Sandalwood, PatchouliMusk - Top Notes: White Woods, Frangipani, Sandalwood - Heart Notes: Carnation, Lily Root, Rose - Base Notes: Musk, Vanilla Flowers, Benzoin, PatchouliCitronella - Top Notes: Lemon, Citronella Essential Oil - Heart Notes: Geraniol, Green Aquatic Notes - Base Notes: Borneol, Wild Lavender, EugenolSandalwood - Top Notes: Oriental flowers, Sandalwood - Heart Notes: Vanilla, Amber - Base Notes: Palo Santo, MuskNag Champa - Top Notes: Patchouli, Sandalwood, Woods, Tobacco - Base Notes: Tolu Balsam, Vanilla.
