Brown Plastic Bottle, Black Cap, 150 ml

A plastic medicine bottle with a black screw cap forms a ready-to-use set for filling liquid products with a nominal volume of 150 ml. The bottle is made of amber PET, which limits the amount of light reaching the contents. It is therefore suitable for massage and body oils, facial toners, hydrosols, hair tonics, and liquid soaps and shampoos that are dispensed by pouring. The HDPE cap has the same neck finish as the bottle, so it simply screws on and you do not have to look for a suitable closure.

The whole set is approved for direct contact with food, so you can also use it for homemade herbal oils, syrups, vinegar infusions or tinctures for the kitchen. Both the bottle and the cap are also declared suitable for contact with cosmetic products. The declaration of conformity is available with the product. The plastic is light and unbreakable, which you will appreciate when posting parcels, travelling and wherever glass poses a risk.

What the set is suitable for

• Body oils and oil serums – the amber material dampens the light that speeds up the yellowing of oils, and the narrower neck of the medicine bottle lets you pour a smaller amount without spilling.
• Toners, hydrosols and facial waters – water-based products without a pump or sprayer, applied to a cotton pad or into the palm.
• Liquid soaps, shampoos and shower gels in smaller packs – 150 ml is a suitable size for samples, travel packs or for trying out a new recipe before making a larger batch.
• Food liquids – flavoured oils, syrups or herbal infusions, where you need packaging certified for contact with food.
• Technical solutions in home production – for example a ready-made preservative solution or a diluted surfactant that you prepare in advance and need to keep clearly separate from cosmetics.

Filling and volume

Nominal volume is the amount the bottle is intended for with normal filling. The brimful volume is the physical volume of the bottle up to the neck and is slightly larger. The difference between them forms a margin 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. An overfilled bottle pushes the contents into the thread when closed, and the cap then does not seal cleanly.

Handling the packaging

Before the first filling, wash the bottle and the cap, disinfect them with isopropyl alcohol or ethanol and leave them to dry freely with the neck facing down. Residual water in the packaging shortens the shelf life of cosmetics and causes cloudiness in oils. Repeat the same procedure for every reuse. Both PET and HDPE withstand normal washing in warm water with washing-up liquid. However, do not put them in a dishwasher or in hot water, as the material may become deformed.

Pour in the contents only after they have cooled to room temperature. A hot emulsion or a freshly boiled syrup may pull the wall of the bottle inwards. After the cap is screwed on, negative pressure forms and permanently deforms the bottle.

PET and HDPE are both plastics that are commonly sorted. Before discarding, it is enough to empty the bottle and rinse it.

Cap and neck

The cap in the set matches the neck of the bottle, so the set is ready for immediate use. If you want to combine the bottle with another closure, for example a dropper or a sprayer, choose closures with the same neck finish stated in the parameters. You will find ready-made combinations and closures sold separately in the Handymade range. With your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.
