Yes, the glass bottle is suitable for most oil‑based and slightly viscous preparations, such as facial oils, oil serums or lighter massage blends. For very thick products, we recommend choosing a suitable type of closure or dosing system (for example a dropper or applicator) and always testing in advance how the specific formulation behaves in the selected combination of packaging and closure.

The glass packaging can be reused provided that hygiene principles are followed. Before each new filling, the bottle must be thoroughly cleaned and disinfected in order to minimise the risk of microbial contamination and undesired interaction with residues of the original product. For disinfection, we recommend using a suitable alcohol‑based preparation, for example isopropyl alcohol or ethanol of technical grade purity intended for this purpose. On Handymade you will find, for example, the products IPA 99 % isopropyl alcohol and Ethanol 96 % denatured plant‑based, which are suitable for professional cleaning of packaging before reuse.

Before reuse, we recommend mechanically cleaning the bottle (rinsing with warm water and a suitable cleaning agent), then rinsing thoroughly with clean water and allowing it to dry. As the final step, it is advisable to carry out disinfection using alcohol – for example by using the product IPA 99 % isopropyl alcohol or Ethanol 96 % denatured plant‑based. After the alcohol has evaporated, the bottle is ready for refilling. In professional manufacturing, always follow your internal hygiene and GMP procedures.

If you decide not to reuse the packaging, we recommend recycling it according to the material composition specified in the product parameters. The glass parts (bottle) are usually placed in the glass recycling container, and the metal closure belongs in metal collection or in sorted waste according to local rules. Before handing it over for recycling, it is advisable to remove any product residues and give the primary packaging a basic rinse. Always adapt the specific recycling instructions to the composition specified in the parameter table and to the waste sorting rules in your municipality.

To select suitable packaging, you can use the advanced filter located at the top of the page after clicking on a particular packaging category. In the advanced filter, you can combine several criteria at once – for example the type and diameter of the neck, the packaging size, the material colour or the required material (glass, plastic, etc.). This allows you to quickly narrow down the offer to packaging options that best match your formulation, the desired dosing and the design of the final product.
