Hello everyone! I was looking for information about all of the things I need for my business and I haven't found 100% information for it. Brief about the company: I want to open my own factory of cold pressed oils for skincare and hair care, but I understand, that I need to do everything in a correct order. I have tried to contact start-up supports and etc, but I have very specific questions and they have answers for the basics as accountancy. Production bits - I have done it already, maybe I would need some guide of keeping conditions, but other that that its OK. So as I am planning to start a business which manufactures oils from seeds and nuts, which will be consumed by humans on skin, hair and possibly - for oral consumption. I assume, that all of that must be certified, tested and etc as it could be unsuitable for some reasons. Where I would need to start with? Testing laboratories or some other authorities? Also a big question I have - shelf life? Who does check the shelf life, who does tests on that? Long story short - if I want to open skincare, hair care cosmetics - what do I need from A to Z? (Skip the production big as it's ready) Also, wouldn't be able to ask all stuff, so later on may add other questions! If something is unclear - just ask and I'll try to answer. Thanks for your time and answers!
