Interesting, thank you!Cosmetic testing, certification, etc is my remit, so let me explain a little how it works.
To certify you must send the base recipe and a certain amount of modifications, e.g scent, colour, active ingredients, to a certification lab. You don't need to send any actual product. They certify that your products are safe to use, you pay them, and then as long as you stick to the recipe and percentage amounts exactly then everything is fine and covered. The modifications are generally not to be more than 10% of the recipe, so 90% of the base needs to be the same across all types of item. You could certify each and every item alone, but it's not really cost effective and as we know ZB creams are all the same base with minor changes.
Listing ingredients is a MUST. They have to be listed in order of percentages first: e.g shea butter as the main ingredient would be first. The only exception is anything 1% or below can be listed in any order at the end. Any bath/body/makeup product must also state at least the postcode of whoever the responsible person is, aka, whoever is listed as the certified person. No-one else is allowed to make the item; I believe ZB has said before only she can make the creams, and that is why. If you can't display the responsible person's information on the product then it must come with it and be in a prominent position in the box or outer packaging.
There is no way her creams were certified originally, when there were no ingredients. She likely got certifications when she formally registered the business. However, as a certified responsible person, she should know she's not allowed to make sweeping claims about cures for particular conditions. She can suggest that a product "may help" at best.
A couple of day ago someone asked if you need to certify products for sale on Etsy, I assume it is necessary, but could you confirm? Thank you
