Blue Glass Bottle, Black Spray, 100 ml

Glass bottle with sprayer, blue, 100 ml is a ready-made combination of a blue glass bottle and a black plastic sprayer, ready for filling liquid cosmetic preparations applied as a spray. Blue glass reduces light transmission, helping to protect light-sensitive contents such as hydrosols, tonics or preparations with essential oils. The sprayer dispenses contents in small doses, making it easier to apply evenly to the skin, body or hair without hand contact with the contents.

The set is particularly suitable for facial and hair mists, tonics, hydrosols, refreshing body sprays, alcohol-based solutions and other thin liquids with a nominal volume of 100 ml. Both the bottle and the sprayer are declared suitable for contact with cosmetic products and the set as a whole is intended for cosmetics.

Why choose this combination

• Light protection – blue glass transmits less light than clear glass, which slows down unwanted changes in light-sensitive contents. It does not replace preservation or antioxidants in the formulation, however.
• Hygienic dispensing – contents are applied by pressing the sprayer, not by pouring or finger contact, which reduces the introduction of impurities into the product during use.
• Glass without interaction with contents – glass does not react with alcohol or acidic environments, making it suitable for tonics with lower pH and alcohol-based solutions.
• Tube reaching the bottom – the suction tube of the sprayer reaches the bottom of the bottle, so the contents can be used up almost entirely.
• Reusable – the glass bottle can be refilled after washing and disinfection; the sprayer just needs to be rinsed and left to dry.

What preparations is the set suitable for

The sprayer is designed for thin liquids. It performs best with hydrosols, facial and hair tonics, thermal and mineral sprays, refreshing body mists, alcohol-based solutions and perfumed waters with low viscosity.

Thick oils, emulsions and gels cannot be evenly dispersed by the sprayer and risk clogging it or causing the contents to run down. Lighter oil blends should be tested in advance. If they do not spray well, a bottle with a pump or dropper is a better choice.

Nominal and total volume

Nominal volume is the volume the container is designed for under standard filling conditions. Total brim-full volume is the physical volume of the bottle up to the neck. The difference between them provides clearance for the sprayer's dip tube and for the expansion of the contents when the temperature changes. The bottle is therefore filled to the nominal volume, not to the brim. An overfilled container will overflow when the sprayer is attached, and temperature changes may push the contents out through the seal.

What is good to know when working with the container

Before the first fill, we recommend washing the bottle, rinsing it with ethanol or isopropyl alcohol and allowing it to dry completely. The sprayer just needs to be pumped several times with clean water or alcohol and left to dry with the tube facing down.

The plastic sprayer is made of polypropylene, which handles common cosmetic liquids and alcohol well. For formulations with a higher proportion of essential oils or solvents, we recommend checking in advance whether the material softens over time and whether the scent of the contents changes. The tightness of the assembly, dosing and sprayer behaviour with a specific formulation should always be tested on one unit before larger production runs.

Blue glass reduces light but does not block it completely. Even in this container, preparations sensitive to light and heat are better stored away from direct sunlight.

When recycling, glass and the plastic sprayer are sorted separately, so unscrew the sprayer from the bottle before disposal.
