Amber Glass Jar, Black Plastic Lid & Gasket, 15 ml

A dark brown glass jar 15 ml with a black plastic lid and inner insert is a complete ready-to-use packaging for cosmetics in small quantities. It is suitable for eye creams, balms, solid perfumes, ointments or samples of larger products. Brown glass reduces light exposure, making it particularly suitable for formulations with vegetable oils, butters, essential oils and active ingredients that lose stability in light.

The complete set is declared as suitable for contact with cosmetics; the declaration of conformity can be found on the product page. It is not approved for food contact and is therefore intended exclusively for cosmetic and technical use.

Key benefits

• Light protection – dark brown glass transmits less light than clear glass, so oils, butters and fragrant components oxidise more slowly and retain their scent and colour longer.
• Glass does not react with the contents – the jar handles even concentrated and anhydrous formulations with essential oils or alcohol that could soften a plastic container.
• Inner insert under the lid – the white PP insert separates the contents from the lid, improves the seal and prevents cream from getting into the thread and making the lid stick.
• Small volume without waste – the contents are used up before they start to age, making the jar suitable for more expensive active formulations and for samples.
• Reusable – both glass and PP can be washed and disinfected, so the jar is also suitable for testing new formulations in small batches.

Use and filling

The jar is filled to the nominal volume, not to the rim. The nominal volume is the quantity for which the container is designed under normal filling conditions. The total volume to the rim is the physical volume up to the neck. The difference between them provides clearance for the inner insert and lid, as well as space for the contents to expand with temperature changes. The exact values of both volumes are listed in the product parameters.

For balms and butters that are poured hot, the melted mass is poured into the jar and left to set completely at room temperature. Only then should the insert and lid be fitted. If the contents are sealed while still warm, moisture will condense under the lid and water droplets will form on the surface of the balm. Thick cream or ointment is best dispensed into the narrow neck with a spatula or from a piping bag to avoid smears on the walls.

Before first use, we recommend washing the jar, insert and lid, disinfecting with isopropyl alcohol or ethanol and leaving to dry completely. This also applies to repeated use. Residues of old contents and moisture are the most common cause of spoilage of a new filling. The lid is tightened by hand without force. The thread on the glass retains its seal only as long as it is not overtightened.

Suitable for products such as

• Eye creams and cream serums – the small volume matches actual usage and the brown glass protects sensitive active ingredients.
• Lip balms and solid perfumes – anhydrous formulations with waxes and butters that are poured hot and hold their shape well in glass.
• Concentrated face creams and night masks – formulations with a higher proportion of oils and vitamins where light protection is worthwhile.
• Samples and test batches – during formulation development or when sending samples to customers.
• Massage and herbal ointments – thick contents scooped with a finger or spatula through the wide neck.

The jar is not suitable for water-based and liquid products such as tonics or serums with low viscosity. It lacks a dispensing mechanism and the contents would quickly become contaminated when scooped with a finger. For such formulations, we recommend a bottle with a dropper or pump.

Good to know

The jar is opened with every use and the contents are scooped with a finger. A formulation containing water must therefore be reliably preserved and its pH must correspond to the preservative used. Anhydrous balms do not require a preservative, but it is recommended to add an antioxidant, such as tocopherol, to prevent the oils from oxidising.

The lid and insert are made of polypropylene. PP is resistant to most cosmetic oils and butters. However, with a higher proportion of essential oils, limonene or solvents in the formulation, it is worth checking that the insert does not deform after a few weeks and that the seal holds. Glass does not react with the contents, so the protection of the contents depends primarily on the quality of the closure.

For a low jar, a round label on the lid and a narrow band around the body work well.

Closures with the same neck type and other ready-made container and closure combinations are available in the Handymade range. For a custom combination, we recommend verifying the seal and the behaviour of the container with the specific formulation. Glass goes in glass recycling, the lid and insert in plastics; disassemble the set before recycling.
