Yes, the glass jar is suitable for packing oily and oil-based formulations such as balms, butters or ointments. Glass is a stable material that typically does not react with cosmetic oils, waxes and active substances. For any new formulation, however, we recommend making a trial batch and a short-term storage test to verify how the specific formulation behaves over time.

The jar can be reused if correct hygiene practices are followed. Before each new filling, the packaging must be thoroughly cleaned and then disinfected with a suitable product – for example with isopropyl alcohol IPA 99% or plant-based ethanol Ethanol 96% denatured. Only after complete drying and evaporation of the alcohol is the jar ready for refilling.

First mechanically remove any residue of the original product, then wash the jar in warm water with an appropriate cleaning agent and rinse thoroughly so that no detergent residues remain. After drying, we recommend disinfecting the inner surface and the thread using alcohol (ALK001 / ALK002), for example with the products IPA 99% or Ethanol 96% denatured. Once the alcohol has completely evaporated and aired off, the container is ready to be refilled.

If you decide not to reuse the jar, we recommend recycling it according to the material types specified in the product parameters. The glass part, once cleaned, should be placed in the container designated for glass. The lid should be sorted according to the material specified in the description – usually this is metal or plastic, which belongs in the corresponding collection container. Before handing it over to separated collection, we recommend removing product residues so that recycling can take place efficiently and in accordance with local waste-sorting rules.

To choose suitable packaging, you can use the advanced filter, which appears at the top of the page after clicking on the relevant packaging category. In the advanced filter, products can be clearly sorted according to several parameters such as neck type, size, colour and material. Thanks to this, you can quickly find bottles, jars, vials or other containers that will best match your specific formulation as well as the visual style of your brand.
