    Hello,

    I would like to know what fixatives do you recommend to use in an alcohol based perfume (EU regulation compatible, possibly available at EU distributor)? I’m planning to make christmas gifts for family and friends, this would be my first time formulating perfumes so it would be great to hear about your experience.

    Thank you!

    I see regularly Diethylphtalate in “parfumer’s alcohol” or “diffuser liquid” mixtures.

    Phthalates were very effective fixatives as @fareloz mentions but are discouraged or banned from use now due to safety concerns. Private use of phthalates is no problem but should you go to market with this try using triethyl citrate or ethylhexylglycerin.

    @chemicalmatt

    Would you be able to recommend a range for including ethylhexylglycerin as a fixative? Thank you!

    If your focus is on the fragrance, some essential oils are just used for anchoring the other EOs. For example, benzoin is a fixative, slowing the dispersion of essential oils and other fragrance materials into the air. And the fragrance is very vanilla, warm and sweet. It may fit your Christmas theme.

    Also, benzoin will not have the same fragrance depending on its variety. For example, Laos benzoin will be vanilla and caramelised without being too sweet. Siam benzoin is the most sought after by perfumers, is much rarer, and therefore much more expensive. It has a much more assertive vanilla character and is very sweet. The CoAs should tell you the origin of each oil.
