    We use Mikrocount Duo kits and have test results periodically validated by a registered external lab. Our production facility is GMP Certified, and this approach is acceptable to the GMP Auditors.

    We were looking at those kits as well. Just curious, how often are you testing?

    I’ve seen the EcoSmart products in Home Depot for a few years, looks like they are claiming all essential oils as active ingredients. Not sure how effective they are though…no preservative to speak of either which is interesting.

    Great, thank you all!

    @Bobzchemist - any suggestion on a good water-soluble anti-oxidant?

    Great, thank you both. Seems like the visual inspection is the best way to go for now. 

  • @heraklit - most formulas can tolerate a bit of rounding. Never understood why people go to the trouble of saying a product needs such a specific number, when most of the time the guy compounding is just going to round up or down anyway.

    Unless you have a ton of money to burn, I would suggest staying clear of traditional brick and mortar retailers. You are going to be competing head-on with brands that are putting millions into advertising and will most likely get lost on the shelf (assuming you can get on the shelf in the first place!). 

    The next generation of retailing is Amazon. Amazon is eating brick and mortar retailers for lunch. And you know what the great thing is? You can literally get your product loaded and ready for sale in an hour. You should seriously check out becoming an Amazon FBA seller. FBA stands for “fulfilled by Amazon”. So, basically you will send in your products to the various Amazon distribution centers and they will fulfill the orders when customers order your product. You can also choose to ‘drop ship’ from your own facility, but will lose the millions of Amazon prime customers who are out there. 
    Anyways, just my thoughts. Good luck and congrats either way!
  • If you paid with a credit card you could always file a chargeback. You will have to state that goods (formulation prototypes) were not received. Otherwise if you say it was a ‘service’ related dispute the credit cards won’t get involved. 

    Otherwise you’ll have to go to small claims court in their home state if you want a shot at recovering the money. I’d say trying to ‘mediate’ is just a waste of time at this point if the person isn’t returning your calls. You need to shake them up and get their attention.

    @ozgirl


    Thanks for your comments. I agree that making a qualified claim would be a better method, all the tech data for our surfactants show they are readily biodegradable. I’m still confused though, if my formula is 90% water, wouldn’t it automatically be defined as ‘readily biodegradable’ since the threshold is 70% removal of DOC and 60% of ThOD?

    On a side note I started getting quotes on OECD biodegradable testing and they range from $1,500 to $4,500 USD for one sample! Seems quite high for what is being done. Anyone know of a cost effective lab who does this type of testing at a reasonable price?

    Hi, thanks for your reply. Yes I am familiar with OECD testing, but this is more of a marketing question. If 99% of a formula breaks down within the 28 days threshold would you still claim biodegradable?

    We also bought an LX900 to create short-run labels. I completely agree that the ink yield is absolutely horrible and the toner is ridiculously expensive. However, we found a 3rd party you can buy replacement ink/chips from at a fraction of the cost. PM me and I can get you their details :)

    Thank you for your reply. Let me before clear then. I measured 100ml of the emulsion and it weighed 99.96 grams. Therefore it is logical to assume that the finished product should weigh 458.79 lbs. Yes I realize this is an “ancient” system, but one that is used by most USA manufacturers (where this forum is located) use when selling raw materials.

    Also most emulsions are closer to 1.0 as there is more water content than oil…
