Amber Round Sirup Glass Bottle, 28 mm, Black Cap, 300 ml

Yes, the glass dropper bottle is suitable for both homemade and professional cosmetic mixing, especially for serums, oil blends, active concentrates and toners. Glass provides a stable environment for most common cosmetic raw materials. However, we always recommend testing the specific formulation first in a smaller quantity and monitoring its behaviour during storage (colour, scent, any changes in viscosity) before filling the entire batch.

The packaging can be reused provided that basic hygiene rules are followed. Before each new filling, the bottle must be mechanically cleaned and then thoroughly disinfected with a suitable disinfectant, for example isopropyl alcohol or ethanol. For disinfection, you can use the products IPA 99% isopropyl alcohol or ethanol 96% denatured vegetal. Only after the alcohol has completely evaporated and the inner surface of the packaging has dried is the bottle ready for refilling.

To verify compatibility, we recommend filling a smaller test amount of the product into one bottle with the selected closure and observing it for several days to weeks under normal storage conditions. Check in particular the tightness of the closure (whether there is any leakage), the condition of the seal, any changes in the colour or consistency of the product and whether there is any plastic odour or altered dosing. For formulations with a higher content of alcohol or essential oils, a longer stability test is particularly important.

If you decide not to use the packaging further, we recommend placing it in separate waste collection according to the material specified in the product parameters. As a rule, the glass bottle can be placed in a container intended for glass after being emptied and basically rinsed. The closure (if made of plastic or metal) should be separated and sorted according to local rules for plastic or metal collection. Before recycling, remove any product residues so as not to contaminate other sorted waste.

To choose a suitable packaging, you can use the advanced filter located at the top of the page after clicking on a specific packaging category. In the filter it is possible to combine several parameters at once – for example the type of neck, size, colour and packaging material. Thanks to this, you can easily find the bottle, jar or pot that will best match your formulation, the required dosing and the visual style of the final product.
