Yes, the glass dropper bottle is also suitable for thicker oil-based or slightly viscous formulations, provided you choose the correct type of closure or dispenser. For oils, serums and nourishing concentrates, droppers or precise applicators are commonly used, which facilitate dosing and reduce the risk of contamination of the neck. Before final bottling we recommend carrying out a trial filling to verify the smoothness of dosing and the comfort of use with the specific product.

The glass packaging can be reused if hygiene principles are observed. Before each new filling, the bottle must be thoroughly cleaned, any residues of the original product removed, and then disinfected with a suitable alcohol-based preparation, for example with the products IPA 99 % isopropyl alkohol or Etanol 96 % denaturovaný rastlinný. This minimises the risk of microbial contamination and unwanted changes in the fragrance or texture of the new preparation. When changing the type of product (for example from oil-based to water-based), we recommend paying extra attention to cleaning and disinfection or using new packaging.

We recommend storing filled glass dropper bottles in a dry, cooler place, away from direct sunlight and sources of heat. It is important that the closure is always tightly screwed on, which reduces the contact of the contents with air and moisture. For more sensitive cosmetic formulations or extracts, storage in closed cabinets or drawers has proven effective, as the packaging is also protected there from temperature fluctuations. Always follow the recommended storage conditions for the specific recipe or raw materials you are using.

If you decide not to use the bottle further, we recommend recycling it according to local waste-sorting rules. The glass parts of the packaging (the bottle body) usually belong in the container designated for glass. Before disposal, it is advisable to remove any product residues, possible plastic or metal components of the closure and paper labels, if possible. Information about the material used for the specific product can be found in the parameter table on the product page on Handymade, and based on that you can choose the appropriate sorting method. In this way you support the recycling process and reduce the amount of unnecessary waste.

To choose a suitable bottle, dropper bottle or other packaging, we recommend using the advanced filter in the packaging category. After clicking on the relevant category on Handymade, you will find the filter in the upper part of the page, where you can refine the selection in detail according to several parameters. It is possible to filter, for example, by type of neck, required size, colour of the packaging or the material used. By combining filters, you can quickly narrow down the offer to the packaging that best matches your formulation, dosing method and the visual style of your brand.
