  • The problem of dented detergent bottles

    Posted by oldman20 on December 5, 2023 at 9:03 am

    Hi all! I observed and noticed that the detergent product bottles were dented as if the air inside had been sucked out. The strange thing is that it seems to happen more with 1 specific type (specific liquid detergent fragrance).

    At first I thought it was due to packaging the product while the solution was still hot, but if so, why doesn’t it happen with all scents but more frequently with one particular type? Is there any possible cause? Let’s discuss, thank you everyone

    What material are the bottles made from? It sounds like “panelling” which is especially common in PET bottles.

      The bottles made from HDPE, but problem occurs much more frequently with a particular product type than with the rest (they only differ in perfum)

    Definitely sounds like paneling of your bottles and is generally caused by essential oils, fragrances and some solvents. It is commonly seen with orange solvents (d’limonene) in cleaning products.

    Your best option is to change your bottle or your fragrance.
