Amber Round Sirup Glass Bottle, PP28, Rose Gold Aluminium Cap, 150 ml

An amber glass medicine bottle with a capacity of 150 ml and a rose gold aluminium cap form a ready-made set for filling oils, serums, toners and hydrosols. Amber glass filters out light, which speeds up the oxidation of vegetable oils and degrades sensitive ingredients. This bottle is therefore particularly suitable for oil-based formulations and for products containing essential oils or vitamins. The glass does not absorb fragrances or dyes from the contents and also withstands alcohol-based formulations.

The cap screws onto the neck and is sealed by a liner on the inside. The contents are poured out of the medicine bottle, so the set is intended for products that are dispensed into the palm, or from which a smaller amount is decanted into a travel or working container. The rose gold cap stands out well against amber glass, which you will appreciate for gift sets and for a uniform look across your own small range.

What it is suitable for

• Body and massage oils – amber glass slows down the yellowing of the oil and the change of its scent in light.
• Oil serums and hair blends – formulations with rosehip, hemp or cranberry oil, which spoil quickly in light, and blends with essential oils, which could draw fragrance out of plastic.
• Hydrosols and toners – a stock bottle from which a smaller amount is decanted into a bottle with a sprayer. The rest stays in the dark and closed.
• Bath oils and aftershave oils – products that are dispensed freely into the palm or into water and do not need a pump.
• Alcohol-based facial lotions and tinctures for cosmetic use – glass does not react with alcohol, and a cap with a seal limits evaporation.

Nominal and total volume

The nominal volume of 150 ml is the amount the medicine bottle is designed for in normal filling. The brimful volume is the physical volume of the bottle up to the neck. The difference between them is a reserve for the closure and for the expansion of the contents when the temperature changes. Fill the bottle to the nominal volume, not to the brim. With a full bottle, the contents would be pushed out when you screw on the cap, and a greasy film on the neck would worsen the seal.

Preparation and reuse

Before the first filling, wash the bottle and the cap with warm water and washing-up liquid, rinse thoroughly and disinfect the inside with isopropyl alcohol or ethanol. Leave it to dry completely with the neck facing down. Residual water shortens the shelf life of an oil formulation and is entirely undesirable in an anhydrous product. Do not dry the cap in direct heat, as the seal is made of foam plastic.

The medicine bottle can be used repeatedly. After it is emptied, simply wash it, degrease it and disinfect it again. Check the liner in the cap for compression or swelling caused by essential oils. If it no longer seals, replace the cap; the glass can still be used. An empty bottle belongs in glass recycling and the cap in metal recycling.

Good to know

• Contact with cosmetics – the set is declared as suitable for use with cosmetic products. You can find the declaration of conformity with the product.
• Food – the certificate for direct contact with food applies only to the glass medicine bottle on its own. The set with this cap is intended as a whole for cosmetics, so do not fill it with homemade oils or syrups.
• Changing the closure – closures with the same type of neck fit the medicine bottle, and ready-made combinations with a pump or sprayer are available in the Handymade range.
• Tightening – the aluminium cap has a thin wall. Tighten it by hand, firmly but without tools. If it is overtightened, the thread will deform and the liner will no longer seal.
• Leak test – with hydrosols and alcohol-based lotions, lay the filled bottle on its side on a paper towel for a day. If the towel stays dry, the set seals with your formulation.
• Fragility – glass is heavier and more fragile than PET. When shipping, wrap the medicine bottle separately in bubble wrap and keep it upright.
