Amber Glass Square Bottle, Matte Silver Dropper, 90 ml

A glass bottle with a dropper for oils, serums and concentrates that are dispensed drop by drop and need protection from light. The amber square medicine bottle with a volume of 90 ml comes supplied with a silver matte dropper, so there is no need to look for a suitable closure and the set is ready for filling. It is suitable for facial and hair oils, oil serums, blends of essential oils with a carrier oil or herbal tinctures for cosmetics, where a single dose is taken with the dropper repeatedly and over a longer period.

Both the bottle and the dropper are declared as suitable for contact with cosmetics, so the set is intended for cosmetic products. It is not declared for contact with food.

Key features

• Amber glass – absorbs part of the light that accelerates the oxidation of oils and the breakdown of sensitive active ingredients.
• Square shape – straight walls and a wide base keep the bottle stable on a shelf, even when you work with the dropper in one hand.
• Dropper with a matte cap – a silver cap, a glass tube and a silicone bulb. It dispenses drop by drop without pouring, so you never use more than you need.
• Glass that does not affect the contents – it does not react with oils or essential oils and is also suitable for blends that would gradually damage plastic.
• 18 mm thread – a common neck size. In the Handymade range you will also find other closures with the same type of neck.

What it is suitable for

You can use the set wherever the contents are dispensed precisely and in small amounts. Facial oils and oil serums are applied as a few drops into the palm, and the dropper makes this possible without your fingers touching the contents. It is equally suitable for blends of essential oils with a carrier oil, macerated oils, cosmetic tinctures or scalp concentrates.

Water-based toners and hydrosols can be filled as well, but a dropper is not the most convenient way to dispense water-based contents. In that case, it is worth considering a fine mist sprayer with the same neck. Thick serums with a high proportion of gel ingredients are drawn up slowly into the glass tube, so for more viscous formulations we recommend testing the dispensing before filling the whole batch.

Filling and volume

The nominal volume is the amount the bottle is designed for in normal filling. The total brimful volume given in the parameters is the physical volume up to the neck. The difference is a reserve for the dropper, which takes up part of the space once screwed in, and for the expansion of the contents with changes in temperature. Fill the bottle to the nominal volume, not to the brim.

Good to know

Before the first filling, the bottle and the dropper should be washed, disinfected and left to dry completely. Residual water in the neck or in the tube would introduce moisture into an anhydrous oil, which reduces its stability.

Glass does not tolerate sudden changes in temperature well. Heated blends, for example a macerated oil after heating or melted butters, should first be left to cool and filled only when lukewarm. The silicone bulb and the plastic parts of the dropper come into contact with the contents every time you draw up the liquid. For formulations with a high proportion of essential oils or alcohol, we therefore recommend checking the seal and the behaviour of the dropper with your specific formulation, ideally on a single piece before a larger production run.

The set can be used repeatedly. When changing the contents, wash the bottle thoroughly, rinse the tube and the bulb of the dropper and leave everything to dry, otherwise residues of the old oil would give the new contents an unpleasant smell. Glass belongs in the glass recycling bin. The dropper is made of several materials, so before recycling separate the glass tube from the cap with the bulb.
