Yes, the glass bottle can be reused if hygiene principles are respected. Before each new filling we recommend thoroughly cleaning the container mechanically and then disinfecting it with a suitable alcohol-based preparation, for example isopropyl alcohol IPA 99 % or denatured ethanol. For this purpose you can use the products IPA 99 – isopropyl alcohol and Ethanol 96 % denatured vegetable. Disinfection helps to minimise microbiological risks and increases the safety of the final product.

First we recommend rinsing the container with warm water and a mild cleaning agent and thoroughly removing all residues of the original contents. Then allow the bottle to dry completely. Before the actual filling, it is important to disinfect the inner and outer surfaces of the packaging using a suitable alcohol solution, for example preparations based on isopropyl alcohol or ethanol. On Handymade you can find, for example, IPA 99 – isopropyl alcohol and Ethanol 96 % denatured vegetable, which are practical for quick disinfection of packaging material.

Yes, the bottle is very practical for development and testing purposes. The compact volume and practical shape make it easier to prepare small trial quantities, monitor formulation stability and test different types of dosing. Glass is a stable material that only minimally affects the composition of most cosmetic formulations, so it is suitable for longer-term testing and for storing samples for internal comparison.

If you decide not to use the packaging further, we recommend recycling it responsibly according to the material indicated in the product parameters. The glass part should, after emptying and basic cleaning, be placed in a container designated for glass. The metal aluminium cap should be recycled according to local rules – it usually belongs among metal packaging. Before sorting always remove product residues and, in the case of multi-material elements (e.g. inserts in the cap), follow the recommendations of your waste management authority. In this way you will support material circulation and reduce environmental burden.

To choose suitable packaging we recommend using the advanced filter in the packaging categories. After clicking on the relevant category, a filtering option will appear at the top of the page where you can narrow down the range according to several parameters – in particular the type of neck, required size, colour and packaging material. In this way you can quickly select a bottle, jar or pot that will match your formulation and the visual concept of your brand.

This type of bottle is most suitable for low- to medium-viscosity products – watery solutions, light oils, tinctures, serums or toners. In combination with a suitable closure, dropper or spray head, it is possible to ensure precise dosing drop by drop or in the form of a fine mist. For thicker formulations we recommend choosing applicators with a larger passage or considering another type of packaging, for example jars or pots, which are more practical for creamy textures.
