We recommend using the advanced filter, which can be found at the top of the page by clicking on the category. You can filter by throat, size, colour and material to quickly find the right packaging for your product type.

For thin formulations, tilting the vial slowly and dispensing drop by drop helps. For thicker formulations, it is advisable to test the drip rate and work with a clean neck to ensure the drop forms evenly.

We always recommend that you perform your own compatibility test on the entire kit, especially for formulations with higher proportions of essential oils, fragrance ingredients or alcohol. Verify the seal, dispensing stability and behaviour of the materials when in prolonged contact with your formulation.

Yes, the packaging can be reused if hygiene principles are followed. Before filling, the packaging needs to be cleaned and disinfected (ALK001 / ALK002) - practically you can use IPA 99% or Ethanol 96% - and then let all parts dry completely.

Fill on a clean work surface, use clean utensils and minimise dropper contact with skin or other surfaces. Always close the container after use and for more sensitive products, we recommend working with gloves and taking care to ensure complete drying after disinfection.

If you choose not to reuse the packaging, we recommend that you recycle it. After emptying the glass bottle, clean it and take it to the glass collection. Separate the parts of the dropper by material and sort them according to the rules in your municipality: glass to glass, aluminium to metals, plastic to plastic; include silicone according to local collection options (if separate collection is not available, it usually belongs in mixed waste).
