Yes, the packaging can be used repeatedly if hygiene principles are observed. Before each new filling, it is important to thoroughly clean the bottle and the dropper and then disinfect them with a suitable alcohol-based preparation (for example isopropyl alcohol 99 % or ethanol 96 % denatured plant-based). Perform disinfection on a clean surface, allow the alcohol to evaporate and only then fill the packaging with the final product. For repeated use, we recommend regularly checking the condition of the dropper and the thread.

Before first use, we recommend mechanically rinsing the bottle with a suitable cleaning solution or distilled water and, after drying, disinfecting it with alcohol. You can use for example IPA 99 % or ethanol 96 % denatured plant-based. Spread the alcohol over the inner surface, let it evaporate freely and only after it has completely dried proceed with filling. This procedure reduces the risk of microbial contamination of the finished product.

The easiest way to find it is by using the advanced filter in the packaging category. After clicking on the selected category, a filter panel appears at the top of the page where you can choose according to several parameters – in particular according to neck type, size, colour and packaging material. By combining these filters, you can quickly narrow down the offer to the packaging that is most suitable for your specific product, whether it is drop serums, oils or other liquid formulations.

If you decide not to reuse the packaging, we recommend correctly sorting it according to the material specified in the product parameters. The glass bottle can usually be placed in the glass container after being emptied and rinsed, while the dropper and any plastic parts go into the appropriate container according to the type of plastic. Before recycling, remove any product residues and, if possible, separate the individual materials (glass, plastic, rubber). In this way, you support efficient waste processing in the recycling process.

Glass is generally a stable and preferred material for formulations containing essential oils or alcohol, therefore this dropper bottle is often used precisely for such types of products. However, when designing the formula, always take into account the overall composition, the concentration of active substances and long-term storage. Before introducing it into serial production, it is advisable to carry out your own stability test under real conditions (time, temperature, transport) and verify the behaviour of the closure and the dropper in contact with the specific mixture.
