I would like to have your thoughts on something.
When you put on cosmetic products on Accelerated Stability, how do you put it ?
So what I do normally is I put the cosmetic product in the container that it is going into the market in and then place it in the oven.
But one or my co workers today was wondering when someone uses the lotion or cream they will pump the bottle or open the jar and use. But when we do stability we just put the bottle inside and check up on it every week and there is no much air going inside. This will not tell us the right stability of the product.
According to me the only thing is when a person opens and closes the product or pumps the product out and air goes in is that the microorganisms enter, the stability is not changed. We add the preservative and anti oxidant to do their jobs here, for this case.
My thinking maybe wrong. So I would like to know what you’ll think!
If anyone has any links to tell me more too will do.
