Cleaning shampoo making tank

Currently i am making 200kg shampoo batch every other day and some times everyday. I use inline mixer. Cleaning the tank, pipes and mixer after each batch, opening and reassembling the pipes all take too much time and some shampoo and water are waisted.

My question is: is that ok if i don't wash the tank if i am making new batch each one or two days?

  • I would say no, it is not ok. This would be no good GMP.

    I guess you always open new barrel or packaging of a raw material and that's where the issue could appear. 
    It something goes wrong, it would be really hard to know what batch went wrong or so. Contamination, bad raw material etc ...

    I would agree that you you need to clean it after every batch.

    I would look into buying a bigger tank because as you said you are wasting time and resources making small batches.

    You could probably just make 1 x 1000kg batch a week. It would take a similar amount of time to make a 200kg batch as it would to make a 1000kg batch (maybe slightly longer if you need to heat the batch).

    For surfactants kind of often but for preservatives and conditioners not so often as the quantity i purchase last longer.

    Is the change and use of new package of raw materials the only concern or there could happen a problem for the small amount of product that stays in the wall of tank for one or two days?

    Yes that i a good option. But i wanted to know if there is anyway to eliminate this washing process at all.

    I wish I had an answer for this. From common sense, the leftover material should be well preserved, so it should not be a problem.

    A part of me wants to say it would be ok and I believe some companies would probably do it, but from good GMP, this shouldn't be happening. 

    Perhaps someone else will have something to say about this :)
