Clear Glass Bottle, Silver Black Dropper, 30 ml

Clear glass bottle, black and silver dropper, 30 ml

A ready-made set for dispensing liquid cosmetic preparations drop by drop: a 30 ml glass bottle with a matching dropper in a black and silver finish. The clear glass lets you see the contents, so you can keep track of the colour, clarity and the amount left in the bottle. With the dropper, you take exactly as much as you need, without spilling and without your fingers touching the contents.

The 30 ml volume corresponds to a common pack size for facial serum, a blend of vegetable oils for the face, nail or hair oil, or diluted essential oils for topical use. The set is declared suitable for contact with cosmetic products and is intended specifically for them.

Suitable uses

• Facial and oil serums – liquid preparations applied drop by drop directly to the skin or into the palm.
• Blends of vegetable oils – for the face, cuticles, beard or hair ends.
• Tinctures and alcohol extracts for cosmetic use – the dropper makes precise dispensing into toner or facial lotion easier.
• Diluted essential oils and fragrance blends – an alternative to a roll-on bottle if you prefer to dose drop by drop.
• Samples and test batches – the small volume is suitable for stability tests as well as for gift or trial packs.

Filling and volume

The nominal volume of 30 ml is the volume the bottle is designed for in normal filling. The brimful volume, stated in the parameters, is the physical volume up to the neck. The difference between them provides a reserve for the body of the dropper, which takes up part of the space once screwed in, and for the expansion of the contents with temperature changes. The bottle should therefore be filled up to the nominal volume, not to the brim. If overfilled, the contents are pushed out through the thread when the dropper is fitted and the bottle leaks.

Good to know

Clear glass does not protect the contents from light. For preparations sensitive to oxidation, especially oils with a higher proportion of unsaturated fatty acids, serums with vitamin C or retinoids, and blends with essential oils, we recommend storing them in this packaging away from direct sunlight, or decanting them in smaller quantities for faster use. If the packaging itself is to block light, amber or blue glass is more suitable.

The dropper combines a glass tube, aluminium sheath, plastic thread and silicone bulb. For formulations with a high proportion of essential oils or solvents, we recommend checking the behaviour of the bulb and the seal on a sample before filling a whole batch this way. After washing and disinfection, the empty bottle can be refilled repeatedly. After longer use, check that the bulb still draws well and that the thread seals properly.

Glass does not tolerate sudden temperature changes. Do not pour a hot oil phase into a cold bottle, and do not wash the bottle with hot water right after taking it out of the refrigerator.

You can find closures with the same neck type and other ready-made bottle and closure combinations in the Handymade range. If you make your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

The empty bottle goes in glass recycling. The dropper combines several materials, so dispose of it separately according to its predominant material.
