    Cooling Agent

    Has anyone noticed how much cooling agents are to buy for DIY? Typically $10-$20 for 10ml 10% solution. I want to experiment a bit more with this but have trouble justifying purchasing large enough amounts (especially if I decide I like it). I decided to see how much it would be to purchase the chemical and dilute it, but it doesn't appear to be available in Australia.

    The best compound (there are several) appears to be WS-3, or N-Ethyl-p-menthane-3-carboxamide, also known as W3 N-ethyl 2-isopropyl-5-methylcyclohexanecarboxamide. CAS number 39711-79-0. It has up to three times more cooling affect than methyl lactate (Koolada), but reports I've seen on ECF seem to be saying it's just a bit cooler and cleaner.

    Maximum solubility in PG appears to be 10.7g in 100ml at 20C

    I've currently got a price from Hangzhou Union Biotechnology Co., Ltd. (China.... of course....) for a food grade product.

    The price I have is US$195 including TNT freight. Current exchange rate make that AU$ 270. If 20 people buy in that is $13.50 for enough powder to make up 500ml of concentrate (A lifetime supply?)

    If 50g is small enough to put in a ziplock bag and put in an envelope, express post to you would be $1.50, so a 1/20 share buy-in would be $15

    Please let me know if you'd like a part in this.

    Fab I use koolada in every eliquid. I vape it strong and only add 1%

    So 1ml per 100ml
    500ml of concentrate will make 50 litres of eliquid. We only vape (over estimate for 2 10ml/day) 5 litres a year.

    That's 10 years of concentrate.

    Well it should last five years if you don't mix it all at once :-D

    Just on this I have one icy DIY subzero that I put 4% in the actual concentrate but it ends up being close to 2.3 when you mix.

    I'm going to sound like a real dope here, but what is cooling agent?

    I'm guessing it makes the vape cool lol

    Koolada. Adds the icy throat hit without the menthol taste. So a mouth feeling rather than a taste.

    Sounds intriguing. I use menthol in almost all my mixes. Count me in for 50 ml.

    Did you mean 50g?

    I've had a reply from Hangzhou Biotech. Price is US$195. I'm trying to get confirmation that this includes the TNT shipping. It seems to. US$195 would be AU$270. That means our price per 50g would be $13.50 if we can get 20 people to buy in.

    I'll entertain smaller amounts if people really want to, but honestly this is essentially enough raw ingredient to make 500ml of concentrate for the cost of buying 10ml from most places.

    I'll need to see what 50gm of this looks like, but there's a chance that I may be able to mail this in a ziplock bag in a standard envelope, so like $1.50 express.

    I'll modify pricing etc in the original message.
