Yes, the glass bottle with dropper is suitable for various oil-based, concentrated and active blends where accurate drop-by-drop dosing is important. Glass is a stable packaging material and with common cosmetic formulations it helps to minimize any influence on the scent, colour or efficacy of the contents. However, for very specific or highly reactive substances we recommend performing your own compatibility test of the product with the packaging before final use.

The bottle can be reused if basic hygiene principles are observed. Before each new filling, rinse the packaging thoroughly, remove any residues of the previous product and then disinfect it with a suitable alcohol-based preparation, for example with isopropyl alcohol or denatured plant ethanol. After disinfection, allow the container and dropper to dry completely at room temperature and only then fill them again in order to minimize the risk of microbial contamination.

The glass bottle with dropper is also suitable for carrying a smaller amount of product, for example daily serums or oils, in a handbag or cosmetic bag. Before travelling, always check that the dropper is tightly closed, and if necessary place the bottle vertically in a resealable bag. In the case of larger fluctuations in temperature and pressure (for example during air transport) we recommend making a trial filling and checking whether the closure remains sufficiently tight with the specific formulation.

If you decide not to reuse the packaging, we recommend its recycling according to the type of material stated in the product parameters. The glass part of the bottle can usually be placed in a container intended for glass once any remaining contents have been removed. The dropper and any plastic or rubber components must be sorted according to the material marking or handed over within municipal waste collection if there is no separate collection system for the given material. Always follow the local waste-sorting rules in your municipality.

The simplest way to choose suitable packaging is to use the advanced filter in the packaging material category. After clicking on the selected category, you will find at the top of the page the option to filter according to several parameters – for example according to neck type, size, colour or material. By combining these filters, you can quickly narrow down the range to the packaging that will best match your product and the desired dosing method.
