The dropper bottle is designed to allow precise dosing mainly of liquid and oil‑based preparations with low to medium viscosity. Thicker emulsions or gels may flow more slowly through the dropper, so it is always advisable to carry out a trial filling and verify whether the consistency of your formula is compatible with the chosen dosing method.

The packaging can be safely reused if hygiene principles are observed. Before each new filling, we recommend thoroughly cleaning the bottle and dropper, allowing them to dry and then disinfecting them with a suitable alcohol‑based preparation, for example with isopropyl alcohol or denatured ethanol. This minimises the risk of microbial contamination and prolongs the stability of your formulation.

We recommend storing the filled bottle in a dry place, away from direct sunlight and sources of heat, at a stable room temperature recommended for the specific product type. Always tighten the dropper firmly to minimise air ingress and prevent undesirable evaporation of volatile components. For sensitive formulations, it is advisable to use the packaging after opening within the shortest possible time in accordance with the recommendations for the specific product.

If you decide not to reuse the bottle, we recommend emptying it, cleaning it as thoroughly as possible of any remaining content and then placing it in sorted waste according to the information given in the parameter table for the product. The glass body of the packaging is usually placed in the container designated for glass, while the plastic and rubber parts of the dropper are sorted according to their material. Always follow the local rules for waste sorting and recycling in your municipality or city.

The simplest way to choose a suitable bottle or other packaging is to use the advanced filter in the relevant category. After clicking on the packaging material category, you will find the filter at the top of the page, where you can select a combination of several parameters – for example neck type, packaging size, colour and material. This will quickly narrow down the range to the packaging that will best suit your formula and the desired method of application.
