Clear Plastic Jar, Transparent Lid, 10 ml

The small 10 ml plastic jar with a screw lid is a complete set for samples and small quantities of thicker cosmetic products – creams, balms, butters, scrubs or solid perfumes. Both parts are made of transparent plastic, so you can see the contents without opening. You will appreciate this for sample sets, recipe testing or selling samples at markets and workshops. The set is declared as suitable for contact with cosmetics; the declaration of conformity and related documentation are included with the product.

What the set is suitable for

• Cream and balm samples – the 10 ml content is enough for several applications; the customer can try the product and see its colour and texture.
• Solid and semi-solid products – lip balms, solid perfumes, massage butters, ointments or cream deodorants that are scooped out with a finger or spatula.
• Scrubs and pastes – sugar or salt scrubs in small quantities, for example in gift sets.
• Formulation aid – small batches for monitoring stability, colour or scent without opening the packaging.
• Dry products – loose pigments, mineral powders or bath salts in sample quantities.

The set is not intended for thin liquids. The screw lid protects thick contents from drying out and contamination, but tightness during transport cannot be guaranteed for watery serums or oils.

Nominal and total volume

For each container we state two figures. The nominal volume is the volume for which the jar is designed for standard filling – this is the decisive figure for both the formulation and the label. The total volume to the brim is the physical volume up to the neck. The difference between them provides a margin for the lid and for any expansion of the contents with temperature changes. Fill the jar to the nominal volume, not to the brim – the contents will then not touch the lid and will not be forced into the thread when closing.

What to know when filling

Polystyrene is a hard and clear plastic that looks similar to glass but is lightweight. The price of hardness is brittleness: it can crack if dropped on a hard floor or under strong pressure, so transport the jars in a box and do not fill them under pressure.

Before first use, wash both the jar and the lid, disinfect with isopropyl alcohol or ethanol and allow to dry freely. The lid screws on without much force – overtightening will not improve the seal and is more likely to damage the thread.

Clear plastic does not protect the contents from light. Formulations with sensitive oils, colorants or active ingredients that fade or oxidise in light should be stored in the dark or packed in a dark-coloured container.

The jar can be reused if it has not been scratched during washing – scratches are clearly visible on clear plastic and detract from the appearance of the sample. Both parts are made of the same material and should be disposed of in plastic waste when no longer needed.
