    Default Freezring and coloring fragrance

    Hi all :
    After dissolving the essential oil with alcohol , I want to color it, what suggestions? And what colored materials are called.
    My second and important question: Is there a so-called saving perfume after making it in a freezer or refrigerator? What are the appropriate temperatures? And is there so-called fermentation?

    Hi William,

    the colour additives used in fragrances are primarily dyes - meaning that they are soluble in the medium. Search for cosmetic dyes. Most water soluble dyes are also soluble in ethanol.

    The fragrance may be refrigerated to precipitate lipids (fats, waxes, etc.), or very gently warmed to promote maturation, but after that it should ideally be stored at room temperature or slightly below. A cellar is good for longer term storage.

    Fermentation won't occur if the alcohol content is above 20% volume. For solubility reasons, it should ideally be about 95% volume.

    I have tried food dyes in fragrance and the colour is not stable, particularly red, it fades over time. If you do try let us know your results.
    I'm surprised our usual suppliers haven't seen this as an opportunity to extend their product lines as I would certainly purchase dyes that can be used in fragrances. I have contacted one of them and got a straight out "no we don't sell dyes" . Hint hint. There's a potential market there.

    Kennel, a U.V. filter should help to keep the colour more stable. See below for options:

    UV absorbers aren't really my field, Paul, but what I can tell you is that for cosmetics, the benzophenones (oxybenzone, sulisobenzone, dioxybenzone, etc.) are mostly used because they offer broad-spectrum UV protection and good stability.

    You're welcome, Kennel.

    It's worth mentioning that visible light can also degrade some dyes. Obviously, you couldn't add anything to block the visible spectrum as it would defeat the purpose of using dyes.

    However, antioxidants have been shown to significantly decrease the light fading of some dyes. In one study on natural dyes, vitamin C and a-tocopherol significantly decreased the light fading of woad (indigo dye), for example. The vitamin C caused some slight discolouration (before irradiation), so a-tocopherol may be the better choice, at least for some dyes.

    In another study, vitamin C also reduced the light fading of synthetic reactive dyes. a-tocopherol wasn't tested, but as all three antioxidants tested led to significant improvements, it seems likely that the same would be true for a-tocopherol (especially if the results of previous study are taken into account). A combination of UV absorber and antioxidant worked better than either alone.
