Development of a cosmetic in less than six weeks?
According to the report, that Korean company can develop a product in less than six weeks:
But… is there any way to do stability tests in less than 90 days? -

As far as I can see - It doesn’t say development takes 6 weeks - only taking it from development to production.

There is no way to do adequate stability/safety/compatibility testing in less than 90 days, but many companies take the risk that 60 days of stability is a good predictor of 90 day stability.
Taking a finished, stable formula from the lab to production in six weeks is certainly possible, but everything depends on how busy your staff and factory already are. In every company I’ve worked for, production time is pre-booked for at least a month, preferably two. Slipping a new production batch into the schedule usually means re-arranging a lot of batches - not something you want to do frequently. -
6 weeks? What took so long?

If it is for product development it is possible to do it much quicker. Depending on the product and what is in it. I’m sure most of the “old timers” on here can develop 90% of cosmetic product requests in less than a week. After so many years of doing this your know what will work and not work. Unless it is something new to you. Now, whether they would or not is another question. They may choose to develop it, send it to the customer but let the customer know that they have a sample sitting in the oven and must wait before production.
If it is from development to production, then depending on the situation, if everything goes smoothly I would say 4 weeks is reasonable lead time.

personally, I’d NEVER release anything to production unless it had had a full ISO 11930 challenge test carried out on it - without the results of that test, how will you know how robust it is towards microbial contamination?
the only time I might make an exception would be if it was extremely similar to an existing product, or if the product’s inherent microbial risk was minimal (e.g. if it were anhydrous, or solvent-based)
