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 select the right packaging for your product type.

Opaque black glass does not transmit light and naturally helps limit the effects of UV rays. This is advantageous for formulations where light can accelerate changes in fragrance, color or stability.

Yes, the packaging can be reused as long as hygiene guidelines are followed. Before filling, the packaging needs to be cleaned and disinfected - practically you can use IPA 99% or Ethanol 96% - and then allow all parts to dry completely.

If you decide not to reuse the packaging, we recommend recycling it. After emptying the glass bottle, clean it and take it to the glass collection. Separate the different parts of the dropper and sort them according to the material: glass parts into glass, plastic parts into plastic, aluminium parts into metal; sort the silicone parts according to the sorting rules in your municipality (if separate collection is not available, they belong in the mixed waste).

We recommend performing your own compatibility test of the entire assembly (sealing, dispensing and packaging behaviour in contact with the specific formulation), especially for mixtures with a higher proportion of essential oils, perfume ingredients or alcohol solutions. It is also practical to test the stability of the drip and the cleanliness of the neck on repeated opening.

Fill on a clean work surface, use clean utensils, and minimize dropper contact with skin or other surfaces. For products with higher hygiene requirements, we recommend working with gloves and allowing the container to dry thoroughly after disinfection before filling.
