Clear plastic bottle, 100 ml

A transparent plastic bottle with a capacity of 100 ml is a lightweight, shatterproof container for liquid and low-viscosity cosmetic products where you want to see the contents. Clear PET shows both the colour and the remaining amount, making it suitable for tonics, micellar waters, hydrolats, facial and body oils, serums, liquid soaps in smaller quantities, makeup removers, or homemade sprays. The 100 ml volume matches the standard size for facial cosmetics and also meets the liquid limit for carry-on luggage, making it equally useful as a travel container.

The container is approved for direct contact with both cosmetics and food products, making it suitable for homemade oils, syrups, herbal infusions, or vinegars. The declaration of conformity and related documents are available on the product page.

What makes the bottle practical

• Shatterproof and lightweight – PET withstands drops and carrying in a bag, which is particularly useful for travel sizes, samples, and bathroom products.
• Transparent wall – the contents are visible, including colour, cloudiness, or sediment. Suitable for clear tonics, coloured oils, or layered bi-phase formulations where appearance is part of the product.
• G18x3 threaded neck – the narrow neck allows precise dispensing and pairs with closures suited for pouring, spraying, or drop-by-drop application.
• Suitable for cosmetics and food – one container type works for both cosmetic and culinary production without having to verify material suitability for each application.

Nominal and total volume

Nominal volume is the amount the bottle is designed to hold under normal filling conditions. The total volume to the brim is the physical capacity up to the neck and is always somewhat larger. The difference provides headspace for the dip tube of a pump or sprayer, for the closure insert, and for expansion of the contents when temperature changes. The bottle should therefore be filled to the nominal volume, not to the brim. With a sprayer or pump, leave additional headspace so the contents are not pushed out through the neck when the closure is fitted.

Choosing a closure

The bottle has a threaded neck as specified in the product parameters. Closures with the same neck type as well as ready-made bottle-and-closure combinations are available in the Handymade range. For custom combinations, we recommend verifying tightness, dispensing behaviour, and container compatibility with the specific formulation, particularly for oils and alcohol-based preparations.

What to keep in mind

Material and contents. PET handles aqueous solutions, hydrolats, vegetable oils, surfactant-based preparations, and emulsions well. For formulations with a high proportion of essential oils, pure volatile oils, acetone, or other solvents, we recommend testing material behaviour on a single unit first, as concentrated volatile oils may stress the plastic over time. At concentrations typical in cosmetics — up to a few percent in a carrier — problems generally do not occur.

Heat. The bottle is not designed for filling with hot contents. Allow emulsions and gels to cool before filling, and do not pour molten oils or butters into PET while still hot. Do not sterilise the bottle by boiling or with hot water.

Label. The cylindrical shape with a flat wall makes label application straightforward. A transparent label or a printed design that keeps the contents visible works particularly well on a clear container.

Reuse. The bottle can be refilled after thorough washing and sanitisation. When switching the type of contents — for example from an oil to a tonic — remove all residues, otherwise the new product will turn cloudy. A closure with a dip tube is harder to clean, so rinse it before the contents dry out.

Recycling. PET is one of the most recyclable plastics. An empty, rinsed bottle without the closure goes into the sorted plastic waste stream.
