The aluminium cap is one of the oldest and most reliable cosmetic closure solutions: chemically neutral, corrosion-resistant and leak-proof. This pack of 168 pink glass 100 ml bottles is designed for natural cosmetic formulators and small-business owners who want to build a premium-feel, uniform range — airtight sealed, modern in appearance.
What is included in the pack of 168
The pack contains 168 tinted, translucent pink glass bottles together with 168 matching aluminium caps. Nominal fill capacity: 100 ml. Height: approximately 130 mm, diameter: approximately 52 mm. The total pack weight is around 22.18 kg, with each empty bottle weighing roughly 120 g on average. The aluminium cap fits the bottle neck via a GL18 thread, providing a leak-proof seal for both natural and oil-based preparations.
Pink glass and a branded look
The tinted, translucent pink shade is a decorative, modern solution tailored to the natural cosmetics market. The silvery sheen of the aluminium cap pairs beautifully with the pink body — for many makers, this is one of the cleanest combinations for artisan cosmetic ranges. The glass is chemically inert: it does not react with cosmetic products and contains no plasticisers. Note: the pink glass primarily serves an aesthetic function and does not replace amber glass for UV protection of essential oils — store light-sensitive preparations in a cool, dark place.
Details of the aluminium cap
Aluminium is chemically inert and corrosion-resistant: it does not react with essential oils or cosmetic preparations, does not allow odours to permeate, and contains no BPA, phthalates, or other plasticisers. The internal liner provides an airtight seal. With plastic caps, essential oils — particularly citrus varieties or those with a high monoterpene content — can over time soften or discolour the cap; aluminium is immune to this. It is also easily recyclable.
Areas of use

Cleaning and recycling
Rinse empty bottles with warm water and a mild, alkali-free soap; for stubborn fragrance residues, rinse with 70% alcohol. Clean the aluminium cap similarly — the internal liner requires gentle handling. Do not use a dishwasher: high heat can fade the pink shade and deform the cap's liner. Both the glass and the aluminium are recyclable.
