Before the first filling, we recommend mechanically rinsing both the bottle and the nasal sprayer with a suitable cleaning agent and thoroughly rinsing them with drinking water. It is then important to allow all parts to dry and, before the final filling, to disinfect the packaging with a suitable alcohol-based preparation, such as isopropyl alcohol or ethanol. For this purpose, you can use the products IPA 99 % isopropyl alcohol or Ethanol 96 % denatured plant-based.

Yes, the packaging can be used repeatedly if hygienic principles are observed, especially for your own formulations and smaller batches. However, with every change of contents or after a longer period of use, it is necessary to carefully dismantle the bottle and the spray mechanism, clean them and always disinfect them before refilling, for example using IPA 99 % isopropyl alcohol or Ethanol 96 % denatured plant-based. This reduces the risk of microbial contamination and degradation of the new contents.

For even dosing, it is important that the prepared solution has a suitable viscosity and does not contain undissolved particles that could clog the nozzle. It is recommended to filter the contents before filling and, in formulations with added powder components, to ensure their complete dissolution. After a longer period without use, you can actuate the mechanism several times “empty”, or disassemble the sprayer and rinse the nozzle with lukewarm water or a suitable cleaning solution, then allow it to dry thoroughly.

The simplest way is to use the advanced filter, which you will find at the top of the page after clicking on the selected packaging category. In the advanced filter, you can clearly select the neck type, size, colour and material of the packaging, which allows you to quickly find a suitable bottle, medicine bottle or jar for a specific product. The filter also helps you compare several options and fine-tune the appearance of the packaging to match your brand or the intended dosing method.

The packaging filled with solution should be stored at a stable room temperature, away from direct sunlight and sources of heat. The nasal sprayer should always be tightly screwed on in order to minimize the contact of the contents with air. For sensitive formulations, we recommend monitoring the stability of the solution over time and, in case of a change in colour, smell or consistency, not using the contents. If your formulation has specific requirements for temperature or light, follow the instructions for the specific raw materials.

If you decide not to reuse the packaging, we recommend recycling it according to the type of material indicated in the product parameters. The glass bottle can usually be placed in the glass container after thorough emptying and rinsing. The plastic parts of the sprayer (head, pump, tube) should be separated and disposed of in plastic collection, unless local waste sorting rules specify otherwise. Before handing over for recycling, it is important to remove any product residues from the packaging so that the recycling stream is not contaminated.
