Our Perfume Base has been formulated specifically for crafters. Our progressive perfume base allows you to create high quality perfume blends without having to worry about HAZMAT fees or the hassle of obtaining an ATF license. The perfume base works well with most fragrance oils and some essential oils. Some essential oils may naturally contain moisture and occasional clouding may occur due to insolubility. When using this base do not use more than a maximum fragrance load of 30%. Expected percentages create Eau de Toilette (15%-18%), Eau de Parfum (19%-22%), and perfume (23%-28%).
