Clear Frosted Glass Bottle, 30 ml, 264 pieces

Small glass bottle with a volume of 30 ml and an 18/410 neck finish, supplied in a carton of 264 pcs. Frosted glass diffuses direct light, yet the contents remain visible as a silhouette, so the customer can see the colour of the serum or the level of the oil. The carton pack suits producers who fill smaller batches of facial serums, face and cuticle oils, perfume oils and samples.

Glass does not react with the contents, does not let air through and does not absorb fragrances, so the bottle withstands water-based, alcohol-based and oil-based fills, including blends with essential oils. The packaging is suitable for contact with cosmetic products. You will find the declaration of conformity and the certificate of analysis (CoA) with the product.

Suitable uses

• Facial serums and concentrates – 30 ml is a common serum size with a dropper or pump.
• Facial and massage oils in small packs – glass does not degrade oil fills even after prolonged contact.
• Perfume oils and aromatic blends – neither ethanol nor essential oils damage glass.
• Samples and travel packs – the small volume is useful for testing a new formulation with customers before a larger batch.
• Toners and facial waters in a mini pack – with a fine mist sprayer for an 18 mm neck you get a travel spray.

Volume and filling

Nominal volume is the amount the bottle is designed for in normal filling. Brimful volume is the physical volume up to the neck and you will find it in the parameters. The difference between them is a reserve for the dropper or the pump dip tube, for the air cushion under the closure and for the expansion of the contents when the temperature changes.

Choosing a closure

The bottle has an 18/410 neck finish. You will find closures with the same neck type, as well as ready-made bottle and closure combinations, in our range. If you are making your own combination, we recommend checking the tightness, the smoothness of dispensing and the behaviour of the packaging with your specific formulation, for example whether a thick oil can be drawn up through the chosen dropper at all.

Good to know

Before the first filling, wash the bottles, disinfect them with isopropyl alcohol or ethanol and leave them to dry thoroughly upside down. Residual water in an anhydrous oil or in a serum without a preservative is a common cause of cloudiness and spoilage.

Glass does not tolerate sudden temperature differences. Let a hot emulsion cool to at least lukewarm before filling and do not pour it into cold bottles straight from the fridge.
