    Default Warning - E-Liquid DIY Safety

    ECF advises that persons who have less than 3 months experience of e-cigarette use should not attempt to DIY with e-liquid, as neither the background knowledge nor an appreciation of the safety issues can exist. It is best to wait till sufficient knowledge is acquired, and 6 months or 1 year's experience is better.

    If you cannot answer these questions immediately then you should not engage in DIY:

    1. If a liquid with a nicotine strength of 30mg/ml has 100% by volume VG added, what will be the strength of the resulting liquid?
    2. Is a standard e-liquid more likely to consist of approximately 50% PG and 50% VG; or 20% PG and 80% VG; or 80% PG and 20% VG?
    3. What is the precise name of VG on a bottle that is bought in the USA for the purpose of diluting existing e-liquid?
    4. If you want 18mg nicotine strength liquid, but a supplier only has versions marked 1.2%, 1.8%, and 2.4%, which should be purchased?
    5. What are the exact precautions required when working with liquids containing nicotine?

    To work safely with liquids that contain poisons requires some knowledge. It is not safe to work with potentially dangerous materials without the required knowledge. Anyone who does not know the answers to these and similar questions should only buy commercial e-liquid, insufficient knowledge exists for safe working with potentially dangerous chemicals.


    Safe retail strengths of nicotine
    The highest strength normally available is 36mg, though some suppliers sell 24mg or 30mg as their maximum strength.

    48mg is available from some suppliers (though it is not allowed to be advertised on ECF), but this should not be used without the advice of an expert. It should only be consumed by those with severe cravings while using 36mg, combined with high tolerance to nicotine. There is a very good argument that WTA e-liquids should be investigated first.

    Any strength higher than this should not be used by anyone for the purpose of consumption in an ecigarette, it is specifically for mixing and thus dilution only. For example 60mg can be used for dilution to produce 30mg by diluting it with an equal volume of zero-nic liquid.


    Purchase of bulk e-liquid base
    54mg, 60mg and 100mg liquid (in either PG, VG or PEG-400) is used only for mixing. Some strengths higher than this may be available but they are best avoided except by commercial labs.

    It is diluted down to 36mg or below, for consumption. There is no need to buy any liquid stronger than those above unless you are a commercial manufacturer of e-liquids and have a full-facility lab. ECF advises that you do not engage in any DIY involving the use of bulk e-liquid base unless you have training, and have the correct facilities. Commercial manufacture requires the supervision of a chemist, for several reasons.


    Pure nicotine
    Pure nicotine, of 99% purity, should not be purchased or used under any circumstances, except by licensed laboratories with a fume cabinet and hazmat facilities. It is a highly dangerous poison in this form, and a small spillage on the skin is likely to be lethal.

    Nicotine was used as an insecticide, and when used to fumigate a greenhouse for example it will kill anything living - including any humans unfortunate enough to be inside. 99% nicotine has a strength of 990mg, or 990mg/ml, and is almost ten times stronger than 100mg, normally the strongest eliquid base sold for mixing, which itself is dangerous enough.

    It is as dangerous as pure potassium cyanide.

    Note that pure nicotine is far more dangerous than high-strength e-liquid because it will be rapidly absorbed into the bloodstream if there is a spill on the skin. This is not normally the case with e-liquid because the nicotine seems to be bound or 'locked' by PG and/or VG, and there appears to be a time window in which the liquid may be rinsed off. This will not be the case with pure nicotine.

    Simply opening a bottle of it can result in a room filling with toxic fumes - it should only be handled in a fume cabinet. If you don't have a fume cabinet then DON'T BUY IT.


    No mention on ECF
    Small amounts of nicotine may be used in the manufacture of e-liquid by those qualified to do so. No one else should either buy the raw materials or attempt to use them.

    ECF will auto-censor out any names of or weblinks to dealers anywhere, of any type, that supply pure nicotine. No mention may be made by members or suppliers of such vendors, and attempts to evade the auto-censor will result in a ban on the member or supplier.

    DO NOT MENTION ANY SUPPLIER OF PURE NICOTINE ON ECF.

    This restriction does not apply in the Manufacturers and Wholesalers private forum, or in the Suppliers private forums.
