Clear Frosted Glass Bottle, Black Cap, 50 ml

Glass bottle, translucent milky, with black cap, 50 ml is a complete packaging and closure set for products that are poured or decanted: facial and body oils, serums, tinctures and tonics. The glass bottle with a nominal volume of 50 ml has a milky matte surface that diffuses light while still letting the contents show through, so you can see both the colour and the level of the product. A simple black screw cap closes the bottle without a dispensing element. The set is also suitable for small batches and samples of your own production.

Why choose this set

• Glass without taste or odour – glass is chemically inert, does not react with oils, essential oils, alcohol or aqueous solutions and does not absorb fragrance. It is therefore also suitable for fragrant and alcoholic blends that can soften or discolour some plastics.
• Matte surface diffuses light – milky glass reduces direct light exposure to the contents, but does not replace the protection of dark brown or blue glass. Store oils with a higher proportion of unsaturated fatty acids away from sunlight regardless.
• Cap with sealing insert – the black polypropylene cap with a 18/410 thread has an internal foam insert that seats against the neck and prevents leakage. The contents are poured directly from the neck.
• Volume for small batches – 50 ml corresponds to a standard packaging size for a facial oil or serum lasting several weeks of use and is also practical for test batches of a new formulation.
• Declared suitability for cosmetics – both the bottle and the cap are suitable for contact with cosmetic products; the EU declaration of conformity is issued by Handymade and can be found with the product.

Nominal and total volume

When filling, it is useful to distinguish between two figures. Nominal volume is the quantity for which the bottle is designed at normal filling and which is stated on the label. Total volume to the brim is the physical volume up to the neck. The difference between them provides a reserve for the cap, any dispensing element, and for expansion of the contents when the temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim. If overfilled, the contents will reach the thread and the cap will not seal properly.

What the set is suitable for

A bottle with a plain cap is suitable for products that are poured or decanted: facial and massage oils, oil serums, tinctures and macerations, cleansing oils, facial waters and tonics applied with a cotton pad. It also works well as packaging for test batches you want to set aside for stability monitoring.

It is less suitable for thick creams and butters that are difficult to remove through a narrow neck, and for products where you need drop-by-drop dispensing or spraying. For such uses, choose the same bottle with a different closure: closures with the same neck type and ready-made combinations are available in the Handymade range. With your own combination, verify the seal and the behaviour of the packaging with the specific formulation.

Good to know

Preparation before first filling. Wash the bottle and cap before use, sanitise with isopropyl alcohol or ethanol and allow to dry completely. Residual water in an anhydrous oil product can promote microbial growth and without a preservative there is nothing to stop it.

Repeated use. Glass can be washed and sanitised repeatedly without any change in properties. The cap wears out with frequent opening and the sealing insert may absorb the scent of previous contents, so replace it when changing products.

Labelling. Degrease the matte glass surface before applying a self-adhesive label. Label dimensions can be found in the product specifications.

Glass and heat. Glass can withstand washing in warm water, but not sudden thermal shock. Do not pour hot contents into a cold bottle or vice versa.

Recycling. Glass goes into glass recycling, the plastic cap into plastic recycling; separate them before disposal.
