Blue Glass Bottle, Matte Black Dropper, 30 ml

The blue glass dropper bottle in 30 ml is a complete packaging and closure set for cosmetic preparations dispensed drop by drop. Blue glass reduces light exposure, helping to protect contents sensitive to light and oxidation – particularly facial and oil serums, blends of vegetable and essential oils, active ingredient concentrates, and tinctures. The dropper enables precise dispensing without spilling, making the set suitable wherever small amounts are taken from the packaging at a time.

The bottle has the shape of a vial – a straight cylinder with a narrowed neck that is easy to hold and to label. The dropper consists of a glass tube, a silicone bulb, and a matte black PP ring that screws onto the neck. The tube length is matched to the bottle height, so the contents can be drawn up even at a low fill level.

What the set is suitable for

• Oil serums and oil blends – glass does not react with oils, and they are dispensed drop by drop exactly where the customer needs them.
• Concentrated active preparations – water-based and oil-based serums with a higher content of active ingredients, where small and repeatable dosing is important.
• Tinctures and alcohol extracts – glass resists alcohol and the blue colour limits the effect of light on the contents.
• Essential oil blends – diluted in a carrier oil; for undiluted essential oils, we recommend checking compatibility with the silicone bulb.
• Samples and small batches – the 30 ml volume is practical for testing formulations as well as for smaller retail packaging.

Nominal and total volume

Nominal volume is the quantity the packaging is intended for during standard filling. Total volume to the brim is the physical volume of the bottle up to the neck and is slightly larger. The difference between them is the allowance for the dropper tube, which displaces some of the contents when screwed in, and for expansion of the contents with temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim. Both values are listed in the product specifications.

Practical use

Before first filling, we recommend washing the bottle and dropper, disinfecting with isopropyl alcohol or ethanol and allowing to dry completely. Fill the contents cooled; glass can withstand heat, but rapid temperature changes are not good for it. Tighten the dropper by hand so the silicone bulb and ring seal properly, but not by force – the glass tube is fragile.

The set is declared as suitable for contact with cosmetics; the declaration of conformity can be found with the product. The set is not declared for contact with food.

Good to know

• Repeated use – the bottle can be reused after thorough washing and disinfection; check the tube and bulb for damage or staining.
• Labelling – the cylindrical shape allows both wrap-around and front labels.
• Water-based contents – water-based serums and tonics dispense equally well with the set, but must be adequately preserved, as the tube comes into contact with skin and air during use.
• Closures – the dropper and other closures with the same neck type, as well as ready-made combinations, are available in the Handymade range; with a custom combination, we recommend verifying the seal and dosing with the specific formulation.
• Recycling – the bottle is glass and belongs in glass recycling; the dropper is a combination of glass, plastic, and silicone, so separate it from the bottle before recycling.
