Clear Glass Bottle, 30 ml, 128 pcs

The 30 ml glass bottle with an 18/410 neck finish is packaging for small quantities of cosmetics. The clear glass shows the contents and their colour, so it is suitable for facial serums, facial and body oils, blends of essential oils in a carrier oil, or herbal tinctures, where you want the contents to be visible. The volume matches a typical serum or oil elixir pack, customer samples, and products that are used up within a few weeks.

The bottle is sold in a pack of 128, which suits small batches as well as production for your own brand. The packaging is suitable for use with cosmetic products and meets the relevant legislative requirements; the declaration of conformity is available with the product.

What the bottle is suitable for

• Facial serums and oils – the clear glass shows the colour of the oil and any added flowers or herbs; the contents are dispensed with a dropper or a pump, depending on consistency.
• Essential oil blends and tinctures – glass does not react with essential oils or alcohol; this applies to alcohol-based tinctures as well as facial toners.
• Water-based toners and hydrosols – at 30 ml this is usually a travel or trial size, for which a fine mist sprayer with the same neck finish is suitable.
• Samples and lab tests – the packaging is also available in technical grade, so it is suitable for storing batch samples and testing the stability of a formulation.

Volume and filling

The nominal volume is the amount the bottle is intended to hold with normal filling. The total brimful volume is the physical volume up to the neck. The difference between them is a reserve for the closure, dropper or pump, and for the expansion of the contents when the temperature changes. Therefore, fill the bottle up to the nominal volume, not to the brim. With a dropper, the reserve is needed above all so that the glass tube fits into the bottle and the contents do not overflow when you close it.

Closures

Closures with the same neck finish fit the bottle, namely droppers, pumps, fine mist sprayers and caps with an 18/410 thread. In the Handymade range you will also find ready-made bottle and closure combinations. If you choose the closure yourself, we recommend checking the tightness and dispensing with your specific formulation, especially with thicker oils and products with a high alcohol content.

Good to know

Clear glass does not protect the contents from light. Oils prone to oxidation, products with vitamins, or products with essential oils are better kept in a box or out of direct sunlight, or you can choose amber or blue glass. Clear packaging makes sense where the colour of the product is part of its presentation and the product is used up quickly.

Glass tolerates heat better than plastic, but when filling, let the mixture cool at least partially. A sudden difference in temperature between a hot formulation and a cold bottle can damage the glass.

After thorough washing and disinfection, the bottles can be reused. Droppers and pumps with rubber or plastic parts are harder to clean after oily contents, so for reuse it makes sense to replace the closure and keep only the glass part. Discarded bottles belong in glass recycling; remove the closure before recycling.
