From a material perspective, the glass dropper bottle is also suitable for formulations with a higher content of active substances or alcohol, because glass has very good chemical resistance and stability. However, we always recommend performing your own test of the specific recipe 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 – dropper bottle is, with proper handling, suitable for repeated use, always, however, with strict hygiene rules being followed. Before each new filling, the packaging must be thoroughly cleaned and disinfected, ideally using alcohol-based products 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 one), we recommend paying increased attention to cleaning in order to prevent deterioration of the new formulation.

For a compatibility test we recommend filling one test bottle with the finished product, closing it with the selected closure or dispenser, and monitoring the behaviour of the packaging for several days to weeks. Focus especially on the tightness of the joint, the smoothness of dosing, changes in the appearance of the glass, any softening of the seal, as well as possible loss of fragrance or changes in consistency. Carry out the test under conditions as similar as possible to real storage (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 that, after emptying and basic cleaning, you recycle it correctly according to the material type 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 make the recycling process easier and reduce the environmental burden. Specific recommendations for sorting may differ slightly depending on local waste collection rules, so it is advisable to follow the instructions of the local collection system as well.

To choose suitable packaging, you can use the extended filter located at the top 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. Thanks to this, you can display only those bottles, dropper bottles, jars or pots that match your recipe and the desired packaging style. We recommend starting with the selection of material and volume, and then adapting the neck and compatible closures.
