Yes, the glass bottle can be used repeatedly, provided that hygiene principles are observed. Before each new filling, the container must be thoroughly cleaned and then disinfected, ideally using alcohol-based agents such as isopropyl alcohol or denatured plant ethanol. After rinsing with the disinfectant solution, allow the bottle to dry completely and only then fill it again.

Before the first filling, we recommend rinsing the bottle with water, washing it with a mild cleaning agent suitable for glass and rinsing it thoroughly. Afterwards, disinfection with alcohol is appropriate – products based on isopropyl alcohol or ethanol are practical. After disinfection, leave the container to dry in a clean environment, ideally upside down on an absorbent surface, in order to minimize the risk of contamination of the inner surface.

If you decide not to use the bottle any further, we recommend recycling it according to the material specified in the product parameters. After thorough emptying and approximate cleaning of any product residues, place the glass part of the packaging in the appropriate glass collection according to local waste sorting rules. The aluminium closure should be separated from the bottle and placed in metal collection, if this is supported in your municipality. In this way you enable material recovery of the individual parts of the packaging and reduce the amount of mixed waste.

The bottle is ideal for concentrated and valuable formulations where precise dosing and protection of the formula are important. It is particularly suitable for facial and hair serums, oil elixirs, active concentrates, essential oils, aromatherapeutic blends, targeted treatments and test series of cosmetic products. Thanks to the combination of glass and metal cap, it looks professional even for smaller editions and hand-made production.

When choosing suitable packaging, we recommend using the advanced filter in the packaging material categories. You can find the advanced filter at the top of the page after clicking on the selected category, where you can clearly set parameters such as neck type, container size, colour and material. Thanks to the combination of these filters, you can quickly narrow down the selection to packaging that best matches your formulation, the desired dosing and the visual style of your brand.

For every new formulation, we recommend carrying out a trial filling of several packaging units and observing the behaviour of the product over time. Focus on sealing of the closure, any leakage, and changes in the product’s scent, colour or consistency in contact with the glass and the metal cap. It is also advisable to verify the functionality of the chosen dosing method (dropping, pouring, application to the skin) under the temperature and storage conditions in which your product will actually be used.
