As a clinical pharmacist who's worked in industry for a short while, DK/Boge is the only liquid I will vape(rarely I'll a try a small bottle of the "fad" US flavor of the month, but that is it). Apostle51's post a few pages back (the one with the pictures and video) says it all. The Chinese(i.e. DK/Boge) are leaps and bounds ahead of US
eliquid manufacturers when it comes to Production teccnology and Quality control/assurance. The facilty(and the airlock/cleanroom technolgy along with a GMP certified process) speaks for itself, but the independent certifications DK/Boge has(from TUV, SGS, ISO, South Korean FDA, etc...), while not quite approaching US FDA cGMP approved status, certainly add a huge amount of legitimacy to their process.
When I have proof that a US supplier is utilizing anything close to airlock/cleanroom technology or at least HEPA certified laminar flow hoods and aseptic technique, I may change my mind.
eliquid is a product designed for direct human pulmonary inhalation and it's production deserves no less than this level of QC/QA.
Also, to the post about Johnson Creek and them being FDA approved, they are not. They have self-registered their facility as per a 2002 bioterrorism act; which required all facilities in the US producing product marketed in the USA intended for human consumption to register. They, nor their product, process or facility, has ever been approved or inspected by the FDA.
As I've now said in countless posts, voluntary implementation , by US eliquid manufacturers or the US eliquid industry in general, of DK/Boge-like process standards would go a long way to help legitimize the entire industry.
I Know, I know, we don't have the money; do you know how much that would cost; we're just a little mom & pop run business etc... I've heard the excuses. If you're serious and want your business/industry to stay around for the long haul(and aren't just in this for a quick buck on an , as yet, unregulated, high margin item) here's what to do. Start re-investing your profits immediately into building a REAL non-cottage eliquid maufacturing firm; obtain a business loan; incorporate and find investors, etc..(you know , all that stuff that legitimate business's do to raise capital). THEN, hire appropriate industry trained personnel or consultants and start the process of building your company into a proper eliquid business(i.e. Contact your local Chamber of Commerce or an appropriate local, State or Federal agency to find out what licensing & recordkeeping requirements are necessary to get up and running or hire someone as a consultant to do it for you; Equip a lab and hire competent, trained lab personnel or outsource to an already existing one for all your pre, inter and post process testing requirements; Create a real, fully equipped manufacturing plant or process structure that is compliant with the latest technology & regulations to ensure safety, quality control/assurance; Create an actual standardized, patented recipe & SOP-standard operating procedure- for it's production, labeling, and packaging in said plant; Hire an attorney and obtain appropriate product Liability insurance to cover your(and the rest of our) ....(s) - This is what SHOULD have been done from the start(back in 2007 or 2008) and the industry might not be in the legal mess it currently finds itself embroiled -
Or don't and keep manufacturing in your kitchen, basement, bathroom, garage. Eventually some local, state, or Federal Bureacrat will be knocking at your door with warrants. Then the fun really starts.
