What is a 15ml glass bottle used for?

Essential oils, face oils, eye serums and treatment serums. It is the standard essential-oil retail size.

How many drops are in 15ml?

About 300 drops, at roughly 20 drops per ml. Dropper size and oil thickness change the count.

Does the 15ml bottle come with a dropper?

No, it is the bottle only. Add any 18mm dropper, pump or cap separately.

Euro dropper or glass dropper: which should I choose?

An euro dropper gives steady drops and a tamper-proof cap, ideal for essential oils. A glass dropper suits serums and face oils.

Product Description

This 15ml glass bottle has an 18mm neck and is sold as the bottle only. Choose amber, amber frosted, clear, clear frosted, blue, green or black. Add a glass dropper, euro dropper, pump or cap to finish it. 15ml is the standard retail size for essential oils and concentrated face oils.

Why a 15ml glass bottle is the essential-oil standard

Many essential-oil brands sell in 15ml, so buyers already know the size. A 15ml glass bottle also suits eye serums and treatment oils. Fit an euro dropper insert for drop-by-drop control. Or use a glass dropper for a serum-style ritual. Amber is the usual choice here, because it blocks most UV light.

Which colour suits your formula?

Colour	Best for
Amber	Light-sensitive oils, actives and essential oils. Blocks most UV light.
Amber Frosted	The same UV protection with a soft matte finish.
Clear	Showing colour and texture. Store away from sunlight.
Clear Frosted	A soft premium look for stable formulas.
Blue	A classic apothecary look. Less UV protection than amber.
Green	Herbal and Ayurvedic ranges. Less UV protection than amber.
Black	Glossy black glass. The most light-blocking option, with a luxury look.
