White plastic bottle, without closure, 100 ml

A white plastic bottle with a volume of 100 ml and a fitted mini trigger sprayer is used for filling and dispensing thin cosmetic liquids. The sprayer disperses the contents into a fine mist, so the product is applied evenly over a larger area and without hands touching the neck of the bottle. The set is sold as a ready-made pair. The neck finish of both the bottle and the sprayer is 24/410, so they fit together without trial and error or buying extra parts.

The bottle is made of PET, is lightweight and does not break when dropped. The white wall reduces the amount of light reaching the contents and hides their colour, which is useful for hydrosols and toners with light-sensitive active ingredients. The sprayer has a white body, a clear overcap and a glossy silver collar, forming a colour-matched set with the bottle.

What the set includes

• 100 ml bottle – white PET with a 24/410 neck finish, without its own closure.
• 24/410 mini trigger sprayer – mechanism and head made of PP, aluminium collar, dip tube reaching to the bottom of the bottle. One press dispenses approximately 0.12 ml, which means several hundred doses from a full bottle.

What it is suitable for

The mini trigger sprayer works with liquids that have a viscosity close to water. This set is therefore suitable mainly for:

• Facial toners and hydrosols – mist application is even and economical, and nothing is poured into the palm.
• Face and body mists – refreshing and moisturising sprays with glycerine, aloe or hyaluronic acid in a low concentration.
• Hair sprays – leave-in conditioners, sprays with hydrosols and water-soluble active ingredients.
• Alcohol-based solutions – disinfectant sprays for hands, tools and work surfaces, and alcohol-based body sprays.

Thick emulsions, body lotions and pure oils do not spray well in a mini trigger sprayer. They produce a stream instead of a mist and gradually clog the mechanism. We recommend testing a small sample with every new recipe.

Filling and volume

The 100 ml figure is the nominal volume, that is, the amount the bottle is designed to hold during normal filling. The brimful volume given in the parameters is the physical volume up to the neck. The difference between the two is a reserve for the dip tube and the sprayer mechanism, and for the air that returns to the bottle during pumping.

Good to know

Preparation before first filling. Wash the bottle with warm water and a drop of detergent, rinse it, disinfect it with isopropyl alcohol or ethanol and let it dry completely with the neck facing down. Screw the sprayer onto a bottle of clean water or alcohol, pump it several times and let it dry.

Reuse. Both PET and PP withstand repeated washing. Before each new filling, repeat the same procedure as for the first use, and after you finish using the sprayer, pump clean water through it so that no residue of the contents dries in the tube and nozzle.

Material sensitivity. The bottle is not intended for aggressive chemicals. For recipes with a higher proportion of essential oils, fragrance compositions or solvents, we recommend leaving a filled sample to stand for several weeks before a larger production run and watching for clouding, softening of the wall or a change in the fragrance of the contents.

Declaration for contact with cosmetics and food. The bottle has a separately declared suitability for use with cosmetic products and for direct contact with food; the declaration of conformity is available with the product. The sprayer does not have this declaration.

Other closures. The neck finish of the bottle is 24/410. You can find closures with the same neck finish and other ready-made bottle and closure combinations in the Handymade range. If you make your own combination, we recommend checking the tightness, dispensing and behaviour of the packaging with your specific formulation.

Recycling. The bottle is a PET plastic with recycling code 1, and the sprayer combines PP and aluminium, so separate the two parts before disposal.
