Caveats: IANAL, and I’m based in the UK where the laws may be different, but I don’t think so.
Basic answer: viz. the perfume, yes, you can do this, but you must be careful about a few things.
First of all, you must not harm the name or reputation of whichever brand you are in fact recycling. It’s best if there is no way for anyone to know or deduce which perfume(s) you are using as your source material, and definitely make sure that the naming, packaging and labelling of your item contains no clues as to the original.
Second of all, you must make it reasonably obvious that your intentions are humorous and jokey, and you do not offer the product for actual use as a perfume nor do you seriously expect it to be considered for use in this way (try to think what a jury would decide if this point ever came to trial). This is to avoid charges of misrepresentation. If people buy your ‘cheap perfume’ because they think it’s a bargain, and entirely miss the ‘jokey’ element, then you could be considered guilty of misrepresentation.
Third of all, you must take care not to be guilty of ‘passing off’, i.e. attempting to benefit IN ANY WAY from the promotion and branding of the perfume which you are re-packaging, or suggesting that your product is worth buying because it is similar to another which already has a good reputation. The law is very clear on this. Companies spend a lot of serious bucks promoting consumer trust in, and loyalty to, a particular brand. Only the company itself is allowed to benefit from that effort and expediture. If you try to benefit from it, in any way, you are guilty of ‘passing off’. First you’ll just get nasty letters from the company which believes its rights have been violated, and after that it gets legally nasty and expensive.
Good luck, have fun.
As regards stuff you can eat: forget it. You have to jump through lots and lots of legal hoops before you can sell consumable stuff, starting with formal investigations of the premises where the products are manufactured before you will be granted a licence. The Health & Safety people will be crawling over you constantly, and if anyone ever falls ill and believes it was because of eating something you sold, I just hope you are very, very wealthy. Don’t go there. not even for fun.
