Yes, the glass bottle can be used repeatedly if hygienic principles are observed. Before each new filling, the packaging must be thoroughly cleaned and then disinfected, ideally using a suitable alcohol, for example isopropyl alcohol or plant-based ethanol. This reduces the risk of microbial contamination and prolongs the usability of the filled product.

The bottle should first be rinsed with a suitable residual solvent (e.g. oil or water, depending on the type of original content), then washed in warm water with a mild cleaning agent and thoroughly rinsed. After drying, we recommend disinfecting the internal surfaces as well as the dropper with alcohol, for example with the products IPA 99 % or ethanol 96 % denatured plant-based. Before filling with a new product, make sure that all parts are completely dry.

The glass bottle with dropper is suitable primarily for liquid and oil-based products with low to medium viscosity that can be dosed drop by drop. With significantly thick gels or balms, dropper dosing may be less comfortable, so for such formulations we recommend performing a trial filling and checking whether the dosing is suitable for the intended use.

The smooth surface of the glass packaging is suitable for applying labels as well as for hand-writing with special glass markers. When designing the label, we recommend considering the adhesion of the adhesive to glass, resistance to oils and moisture, and sufficient space for the mandatory product information. Before serial production, it is worthwhile to test a smaller series of labels directly on filled bottles to verify their resistance during handling.

If you decide not to use the packaging further, we recommend recycling it according to the type of material specified in the product parameters. After emptying and basic rinsing, the glass bottle should be sorted into the container designated for glass. The dropper usually consists of several materials (plastic, rubber, possibly metal), so it is necessary to proceed according to local sorting rules – in the case of composite packaging, it is safest to follow the recommendations of the municipality or the waste collection company. Before recycling, make sure that there are no larger residues of product left in the packaging.

You can find the most suitable packaging for your product using the advanced filter in the packaging material categories. After clicking on the relevant category, the advanced filter is located at the top of the page and allows filtering according to several parameters, such as neck type, size, colour or packaging material. Thanks to this, you can quickly choose a bottle, pharmaceutical bottle, jar or another container that best matches your formulation and the intended way of use.
