30 ml is one of the most popular mid-range sizes in the artisanal cosmetic and essential oil segment: it holds a meaningful quantity for a formulation or a weekly-monthly course of use, while remaining hand-friendly. This 110-piece pack ships with aluminium caps, the best choice for the longest-term storage.
What this 110-piece pack contains
110 amber 30 ml glass dropper bottles + 110 matching aluminium caps. The bottles are approximately 85 mm tall with a 35 mm diameter. The neck uses a standard GL18 thread, compatible with most replacement caps in the category. The package weight is around 0.22 kg per typical handling unit; the full shipment weight depends on the chosen format.
Amber glass and UV protection
Amber glass is one of the best storage solutions for essential oils, botanical extracts and sensitive cosmetic preparations. It filters out the shorter wavelengths of visible light and the UV spectrum — exactly the photocatalysts that trigger active ingredient degradation and scent profile distortion. Glass is chemically inert, neither releasing nor extracting any substance.
Aluminium cap details
The aluminium cap is a solid metal closure with a foam or polycone liner — providing a tight, leak-proof seal. Aluminium is chemically inert, does not react with the more aggressive components of essential oils (citrus or spice monoterpenes), contains no BPA, phthalates or other plasticisers, and imparts no off-flavour or odour. It is a reliable choice for long-term storage and for retail use. Aluminium is also easily recyclable.
Areas of use
- Storage of essential oil synergies and aromatherapy blends
- Bottling of face serums and skincare oils
- Massage oil formulations
- Longer-term storage of botanical tinctures
- Private-label cosmetic development
Cleaning and reuse
Wash the bottle in warm soapy water, rinse with alcohol to remove stubborn scent residue, and let air-dry. Avoid the dishwasher to prevent label damage. Glass and aluminium are each infinitely recyclable when separated.
