Amber Round Sirup Glass Bottle, PP28, White Cap, 150 ml

This amber glass pharmaceutical bottle with a volume of 150 ml and a tall white cap serves as closed packaging for cosmetic preparations that need protection from light. Amber glass dampens both daylight and artificial light, so it is filled mainly with facial and body oils, massage blends, tonics, hydrolates, alcohol tinctures and herbal extracts intended for cosmetics. The cap only closes the bottle and does not dispense. The set is therefore suitable where the contents are poured or measured out separately: in the workshop, for storing semi-finished products, for larger quantities of oils and for transferring finished preparations.

The entire set, that is the bottle and the cap, is declared suitable for contact with cosmetic products. You will find the declaration of conformity with the product.

What the set is suitable for

• Vegetable and macerated oils – a volume of 150 ml suits both home and smaller workshop batches, and amber glass slows the effect of light on oils prone to oxidation.
• Tonics and hydrolates – glass does not react with the water phase or with the preservative. The contents are dispensed by pouring or after decanting into a smaller bottle with a fine mist sprayer.
• Tinctures and alcohol extracts – glass withstands alcohol without any change in appearance or scent, and the thread and cap allow the bottle to be opened repeatedly during steeping.
• Semi-finished products and stock – blends of essential oils in a carrier oil, prepared water phases or finished preparations waiting to be decanted into retail packaging.

Volume and filling

The bottle states a nominal volume of 150 ml. This is the quantity the packaging is designed for in normal filling. The brimful volume, that is the physical volume up to the neck, is slightly larger and can be found in the product parameters. The difference between the two values is a reserve for the cap and for the expansion of the contents when the temperature changes. Fill to the nominal volume, not to the brim. Otherwise the contents will be pushed out by the cap when closing, or will get onto the thread and impair the seal.

Cap and seal

The tall white LDPE cap screws onto the thread of the bottle. Tighten it by hand, as excessive force is more likely to deform the soft plastic than to improve the seal. Before dispatch or transfer, we recommend turning the filled bottle upside down as a test and checking the thread. Concentrated essential oils and some solvents may soften or discolour soft plastic over time. With such contents, test the behaviour of the cap on a single sample before filling the whole batch.

Closures with the same neck type and ready-made combinations of bottle plus closure can be found in the Handymade range. If you are making your own combination, check the seal and the behaviour of the packaging with your specific formulation.

Good to know

Before the first filling, wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in an oil-based preparation shortens its shelf life and has no place in an anhydrous product. The glass pharmaceutical bottle can be reused, but check the cap with each new filling and replace it if the thread is deformed.

Amber glass hides the colour of the contents. When you need to monitor cloudiness, sediment or the colour of an extract, pour a sample into a small clear container. After use, the glass belongs in glass recycling and the cap in plastics recycling.
