  • How do you prevent condensation in your cosmetic bottle?

    I had an interesting question sent to me where the person had a problem with condensation occurring in the top of their bottles when the product was filled and stored over night.

    I was wondering what your strategies are for reducing condensation.  I had one idea and  it will be interesting to see if anyone else has the same idea.

    For lotions, I let them cool to room temperature before bottling.

    Not sure if this idea is sound chemically…but what about a nitrogen blanket?

    With a reasonable budget, I’d use a cooling tunnel after the bottles are filled and capped.

    Perhaps add a tiny amount of a lipid added when bottling will stop the surface  evaporation?

    My idea…

    Store the bottles upside down.  When you turn them right side up, no more condensation problem.

    if it’s a hot mix I’d cool it to room temperature before capping it, and avoid storing it anywhere with widely variable ambient temperatures

    (this is what we do with water-based hot fills in production)

    I think it’s best to allow the filled bottle to cool before capping.

    When I do my canning, I put the hot, filled jars in the oven. The oven is sterilized every time it’s used, so contamination should not be an issue, right?  The oven also has NO air currents to blow icky things into the bottles, whose caps you’ve left OFF while it cools.  

    OR put the bottles into a clean box & close it, to allow the contents to cool before capping? 
    How about using a picnic cooler whose sides & tops you’ve cleaned with alcohol, and closing the lid of the cooler,  to let the bottles cool off?
