Product description

A plastic dropper 28/410 turns an ordinary bottle into a container that dispenses its contents drop by drop. It inserts into the bottle neck and narrows the opening, so the contents do not flow freely. It is suitable wherever a product is used in small amounts and too much would pour out through the full neck: with facial and hair oils, tonics, hydrolates, liquid extracts, or fragrance blends.

It is made of polypropylene (PP) and is suitable for contact with cosmetic products. It is intended for bottles with a 28/410 neck.

How a dropper works

The dropper is pressed into the neck of a filled bottle, where it holds by tight fitting. When the bottle is tilted or turned upside down, the contents come out through the small opening drop by drop. The bottle is then closed with a cap of the same neck type.

Economical dispensing – contents are dispensed drop by drop, making it easy to measure out a small amount.
Lower risk of spilling – if an open bottle tips over, the contents do not pour out all at once through the full neck.
Cleaner neck – contents do not run down the thread and the bottle stays less greasy.
Discreet appearance – clear plastic does not interfere with the look of either clear or coloured bottles.

For which products it is suitable

The dropper is suitable for thin, free-flowing contents: vegetable oils and their blends, facial and hair oils, tonics, hydrolates, glycerin and alcohol extracts. The drop size and dispensing speed depend on the viscosity of the contents. Oil drips more slowly than an aqueous solution, and thicker liquids may flow only very slowly.

For gels, body lotions, shampoos and other thick products the dropper is not practical. A flip top, disc top or pump will serve better for these.

Before filling an entire batch, we recommend testing one bottle with the finished product. This verifies how quickly the contents drip, whether the dropper sits firmly in the neck, and whether the bottle seals properly once closed with the cap.

Good to know

Preparation before first use. The dropper is washed, disinfected with isopropyl alcohol or ethanol and left to dry completely.

Filling the bottle. The bottle is filled before the dropper is fitted, up to the nominal volume, not to the brim. The nominal volume is the amount the bottle is designed for under normal filling conditions. The total volume to the brim is the physical volume right up to the neck. The difference between the two is a reserve for the dropper, which takes up space in the neck, and for the expansion of the contents with temperature changes.

A bottle filled to the brim will overflow when the dropper is pressed in, and the contents will reach the thread. Fill only up to the nominal volume stated in the bottle's specifications.

Selecting a bottle and cap. Bottles and caps with the same neck type, as well as ready-made combinations, are available in the Handymade range.

Recycling. Once it has served its purpose, polypropylene belongs in sorted plastic waste collection.

Frequently asked questions

Which bottles does the plastic dropper 28/410 fit?

The plastic dropper 28/410 is intended for bottles with a 28/410 neck type. The neck type is listed in the specifications of each bottle, so compatibility can be verified before ordering. With bottles of a different neck type, the dropper will not seat correctly, will not hold, or will not seal. When assembling your own combination of bottle, dropper and cap, we recommend testing the seal on one unit.

Is the plastic dropper 28/410 suitable for essential oils?

The plastic dropper 28/410 is suitable for contact with cosmetic products; however, for undiluted essential oils we recommend testing with the specific contents. Fill one bottle and monitor over several weeks whether the dropper changes shape, whether it holds firmly in the neck, and whether the contents change in scent. We recommend the same procedure for contents with a high proportion of solvents.

Can the 28/410 dropper be used for shampoo or body lotion?

For thick products such as shampoos, gels or body lotions, the plastic dropper 28/410 is not suitable. They flow through the small opening too slowly or not at all. The dropper is intended for thin liquids, such as oils, tonics, hydrolates and liquid extracts. For viscous products, a closure with a larger opening or a pump is more practical.

How is the plastic dropper cleaned and can it be reused?

Yes, the plastic dropper can be cleaned and reused. It is washed with warm water and soap, rinsed thoroughly, disinfected with isopropyl alcohol or ethanol, and left to dry completely. After repeated removal from the neck, check before the next use that the dropper still holds firmly and seals in the bottle.

What material is the plastic dropper 28/410 made of and is it suitable for cosmetics?

The plastic dropper 28/410 is made of polypropylene (PP) and is suitable for contact with cosmetic products. Suitability is based on the technical documentation for the packaging. The dropper is offered in both cosmetic and technical quality, so it serves for cosmetic products as well as technical applications. The clear version suits both clear and coloured bottles.
