Amber Plastic Bottle, Silver Aluminium Cap, 30 ml

This amber plastic pharmaceutical bottle with a capacity of 30 ml and an aluminium cap is used for filling smaller amounts of face serums, face and hair oils, extracts or cosmetic samples. The amber colour of the PET reduces the amount of light reaching the contents, so the bottle is also suitable for formulations with light-sensitive ingredients, such as vegetable oils, vitamins or essential oils at a low usage rate. The plastic is light and shatterproof, which comes in handy when sending samples, selling at markets or packing for travel. The silver aluminium cap with an 18 mm thread closes the bottle and can be opened repeatedly. The contents are dispensed directly from the neck by pouring or dripping.

What the set is suitable for

• Face and hair oils – the dark packaging slows the effect of light on oils prone to yellowing, and the small volume is used up before the oil changes its odour.
• Serums and toners in small batches – the 30 ml volume corresponds to a usual trial batch for testing a formulation before larger production.
• Samples and testers – a light bottle with a flat cap is easy to send and hand out, and it will not break in an envelope or a bag.
• Travel size – you can pour an ordinary product from a larger pack into a 30 ml pharmaceutical bottle, which you can wash and reuse when you get back.
• Alcoholic and hydroalcoholic extracts – with a higher alcohol content, check in advance how the bottle and the cap seal behave with your specific contents.

Cap and seal

The aluminium cap has an inner sealing liner made of EPE, foamed polyethylene. When tightened, it presses against the neck of the bottle and prevents leakage and air access. Tightening by hand is enough. The contents are poured or dripped from the pharmaceutical bottle directly through the neck, as the cap has no dispensing element. Closures with the same neck type and other ready-made bottle and closure combinations can be found in the Handymade range. If you choose your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

Nominal and total volume

The nominal volume is the volume the packaging is intended for under normal filling. The brimful capacity is the physical volume of the bottle up to the neck and is somewhat larger. The difference between them forms a reserve for the cap and for the expansion of the contents with temperature changes. The pharmaceutical bottle is therefore filled to the nominal 30 ml, not to the brim. If it is filled up to the neck, the contents splash out when the bottle is closed or get into the thread, and the cap then does not seal.

Good to know

Before the first filling, wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and let them dry completely. No residual water should get into an oil-based product.

Concentrated essential oils and solvents can damage plastic over the long term. For formulations with a higher proportion of essential oils or with solvents, test the behaviour of the packaging on one bottle before filling the whole batch. The packaging is not intended for contact with aggressive chemicals.

The set of bottle and cap is declared suitable for contact with cosmetic products, and the declaration of conformity and certificates are provided with the product. The plastic pharmaceutical bottle alone has a certificate for direct food contact; the aluminium cap does not. The set as a whole is therefore intended for cosmetics.

The bottle withstands repeated use after thorough washing and disinfection. If the sealing liner in the cap loses its elasticity or soaks up its previous contents, replace the cap. At the end of its life, the PET bottle is sorted as plastic and the aluminium cap separately as metal.
