Clear Plastic Bottle, Black Plastic Cap, 18/410, 100 ml

The clear 100 ml PET bottle with a black screw cap is designed for cosmetics that are dispensed by pouring: face and hair oils, hydrolates, toners, massage oils, liquid soaps or travel shampoos. The clear material shows the colour and purity of the contents, so it suits products where you want to see what is inside. The plastic is light and unbreakable, so the bottle holds up in the bathroom, on the road and when sending out samples. The bottle and cap set is declared suitable for contact with cosmetics.

What it is suitable for

• Oils and oil blends – face, body and massage oils are poured in small amounts from the narrow neck, and you can see through the clear wall how much is left.
• Hydrolates and toners – water-based products without a sprayer, applied to a cotton pad or into the palm.
• Liquid soaps and shampoos – a travel pack or a sample for a customer. After use, the bottle can be closed and used again.
• Carriers and bases – small amounts of vegetable oils, glycerine or diluted surfactants, which the maker prepares in advance and sets aside for a formulation.

Cap and dispensing

The black cap with an 18/410 neck finish screws onto the neck of the bottle without tools and withstands repeated opening. The contents are dispensed by pouring; the cap has no dispensing opening. The inner liner sits against the rim of the neck and seals the bottle, which you will appreciate with liquid contents, especially when carrying it.

Filling and volume

The 100 ml figure is the nominal volume, that is, the amount the bottle is designed for under normal filling. The total volume up to the brim of the neck is larger. The difference serves as a reserve for the cap and for the expansion of the contents when the temperature changes, so the bottle is filled to the nominal volume, not to the rim. Pour thicker products, for example liquid soap with a thickener, slowly so that air bubbles do not form in the narrow neck.

Before the first filling, wash and disinfect the bottle and the cap and let them dry completely. Traces of water in an oil-based product shorten its shelf life, and in a water-based product they put a strain on the preservative system.

Good to know

A clear bottle does not protect the contents from light. Light-sensitive products, for example oils with a high proportion of unsaturated fatty acids or vitamin C serums, belong in dark packaging or at least in a box, away from direct sunlight.

The bottle withstands repeated use. After emptying, wash it with warm water and a small amount of surfactant, rinse it, disinfect it and let it dry with the neck facing down. Clean the cap separately so that no water remains under the liner. You can find closures with the same neck type and ready-made combinations of this bottle with other closures in the Handymade range. If you make your own combination, we recommend testing the seal and dispensing with your specific formulation.

After thorough washing, both the PET bottle and the PP cap belong in sorted plastic waste according to the rules in your municipality.
