From a material point of view, the glass pharmaceutical bottle is also suitable for formulations with a higher content of active ingredients or alcohol, because glass has very good chemical resistance and stability. However, we always recommend carrying out your own test of the specific formula in the planned combination of packaging + closure (especially with a high content of essential oils, acids, or solvents) in order to verify long-term stability, sealing, and dosing.

The glass bottle – pharmaceutical bottle is, with proper handling, suitable for repeated use, always subject to strict hygiene rules being observed. Before each new filling, the packaging must be thoroughly cleaned and disinfected, ideally using alcohol-based preparations, such as the cleaning alcohols available in the Handymade range (for example IPA 99 % isopropyl alcohol or ethanol 96 % denatured, plant-based). When changing the type of product (for example from an oil-based to a water-based product), we recommend paying increased attention to cleaning to avoid compromising the new formulation.

For the compatibility test, we recommend filling one test bottle with the finished product, closing it with the selected closure or dispenser, and observing the behaviour of the packaging over several days to weeks. Focus in particular on the tightness of the joint, smoothness of dosing, changes in the appearance of the glass, softening of the sealing, as well as any loss of fragrance or change in consistency. Carry out the test under conditions as similar as possible to the real storage conditions (temperature, light, handling). If you do not observe any undesirable changes during the test, the combination of the packaging and your formulation is usually suitable for use.

If you decide not to reuse the packaging, we recommend properly recycling it after emptying and basic cleaning, according to the type of material stated in the product parameters. The glass body of the bottle is usually placed in the container intended for glass, while plastic or metal closures are sorted according to the relevant fraction (plastic / metal), where possible. Before disposal, remove product residues to facilitate the recycling process and reduce the environmental burden. Specific recommendations for sorting may differ slightly depending on local waste collection rules, so it is advisable to also follow the instructions of the local collection system.

To choose suitable packaging, you can use the advanced filter located in the upper part of the page after clicking on the relevant packaging category. Within the filter it is possible to combine several parameters at once – for example the type and diameter of the neck, the size of the packaging, the colour of the material, or the material composition. In this way you can display only those bottles, pharmaceutical bottles, jars, or pots that meet your formula and the desired packaging style. We recommend starting with the selection of material and volume and then adapting the neck and compatible closures.
