Technical questions from the experienced perfumers!

i am saddened that Im not coming here to BN as much as I want, which is daily! But life and work gets most of us!

I would like to ask some technical questions from experienced perfumers who launched their brand, I hope they can support me on it,

– If I create a perfume formula, how can I copy protect it if I want to send it for production

– if the above question is not feasible, do I have to create the formula concentrate and send it production? if this is the case, it won’t work on large scale and I would have to rent or create a lab? I ask if there’s a way to avoid creating a lab, which will be great help to Start with.

– if I commission a fragrance house example like Firmenich to create a perfume for me, will the formula be mine legally?

– whats the best way to guarantee that the production factory will not tamper with alcohol % and affect the final product?
With example for why I ask, I tried 3 factories here with same formula and I got 3 different results! But that was on a very small scale and without any papers!…
do I need to sign them an agreement in this case, which states that I will do testing for random bottles after production to ensure on quality?

– why did I get 3 results in 3 factories? Could it be more than just alcohol % ? Is there different reasons I should consider? they all use the same alcohol! Could it be that they are not honest about the quality of alcohol?

– do I need to sign with the factory an NDA and NUA agreements? to ensure not to copy or keep some of the concentrate, or replace it, or copy the bottle shape, all of these matters in general?

– is it better to invest and buy machines , and do the process myself?

– if I Invest in machines, do I need to create the place with the same medical lab requirements and quality process?

thank You in advance for your support, i hold a great value of the feedback I receive here, as it came always true and to the point and with most accurate results,

sincere regards
