Yes, the glass dropper bottle is suitable for both oil-based and water-based solutions, as well as for alcohol-based preparations commonly used in cosmetics and artisanal production. For very aggressive or unusual formulations, however, we recommend performing your own short compatibility test to verify the stability of the mixture in contact with the glass and the dispenser.

The container can be reused if basic hygiene principles are observed. Before each refilling, the bottle and the dispensing part must be thoroughly cleaned and then disinfected with a suitable alcohol-based agent, for example with isopropyl alcohol or plant-derived ethanol. After disinfection, allow all parts to dry completely at room temperature, and only then refill them with the new product.

If you decide not to reuse the packaging, we recommend recycling it responsibly in accordance with local waste-sorting regulations. After rinsing out any remaining contents, separate the glass part of the bottle from the plastic dispenser and closures. Place the glass in the appropriate glass-recycling container according to the designation in the product parameter table, and put the plastic components into sorted plastic waste if they are recyclable according to their marking. By doing so, you support the reuse of materials and reduce environmental impact.

Dark glass naturally reduces the penetration of light to the contents of the bottle, which is particularly beneficial for light-sensitive oils, extracts and active ingredients. It helps to slow down oxidation and degradation of certain components, thereby potentially contributing to longer product stability. Nevertheless, we recommend storing finished products in a dry, cooler and shaded place, ideally away from direct sunlight.

The serrated dispenser is primarily designed for liquids with low to medium viscosity that can be dosed drop by drop or in small amounts. With more viscous oils or gel-like textures, the flow may be slower, so we recommend carrying out a trial filling to check whether the dosing speed suits you. If necessary, you can choose a different combination of container and closure from the Handymade range.

To select a suitable bottle, dropper bottle or other type of container, you can use the advanced filter in the packaging category. After clicking on the relevant category, the advanced filter is located at the top of the page and allows you to sort products according to parameters such as neck type, size, color and material. This enables you to quickly narrow down the selection to packaging options that will best suit your specific product and method of application.
