Filed under wholesale cosmetic bottles — start there for the stock moulds, then use the detail below to narrow the spec.
A custom cosmetic bottle is specified as a system: the glass, the closure, the viscosity of the formula and the filling line all have to agree. The decision to make first is the closure, because a dropper, a pump and a flip cap each need a different neck finish and that finish is cut into the mould. Skincare glass runs from 10 ml to 250 ml across four formats, with amber and opal white as the two colours most launch lines are built on.
The four formats and what each one holds
Nearly every skincare range is assembled from the same four glass families. Each suits a certain kind of formula and a certain closure.
| Format | Capacity | Typical contents | Point to watch |
|---|---|---|---|
| Dropper bottle | 10–50 ml | Serums and facial oils, dosed through a glass pipette or a plastic-tip dropper | A dropper finish and a pump finish are not interchangeable |
| Serum or essence bottle | 15–50 ml | Light serums under a screw cap or precision pump | Decide whether glass and closure arrive together or from separate sources |
| Lotion pump bottle | 50–250 ml | Body lotions and thicker creams for daily use | Needs a wider neck, usually a 24 mm or 28 mm thread |
| Cream jar | 30–250 ml | Balms, masks and moisturisers under a screw lid or airless-style fitment | Surface finish and rim tolerance, since the user reaches in with a finger |
Airless and spray versions can also be requested. Whatever the format, treat a change to any one element as a prompt to recheck the rest. A thicker formula may call for a different pump, and a different pump may call for a different neck.
Closure and neck finish come before tooling
The neck finish is the threaded or shaped top of the bottle that the closure grips. Once the mould is made, it is fixed. Choosing the wrong closure family, or changing it late, is the costliest error in cosmetic glass, so settle it with your filler and closure supplier before anyone cuts steel.
| Closure | Neck finish | Suited to | Trade-off |
|---|---|---|---|
| Glass dropper | 18 mm / 20 mm | Thin serums, oils, essences | Looks refined, fills more slowly |
| Plastic-tip dropper | 18 mm / 20 mm | Everyday serums | Lower cost and tougher in transit |
| Screw pump | 24 mm / 28 mm thread | Lotions, creams, viscous formulas | Pump stroke must be matched to viscosity |
| Flip-top cap | Varies | Toners, body washes, shampoos | Quick to dispense, reads as less prestigious |
| Screw lid on a jar | Wide-mouth rim | Balms, masks, moisturisers | The rim must be flat or the lid will not seal |
Dropper type matters to the filling line as well as to the customer. A glass pipette and a plastic-tip dropper do not fill the same way and can need different nozzles. If the pipette's inner diameter is wider than the nozzle specification, the line drips and slows, and the nozzle has to be re-tooled. Confirm with the filling contractor which dropper their equipment is set up for before the mould is ordered.
The same question applies to supply. Dropper bottles can be bought with the dropper included, or the glass and the closure can be sourced apart. Find out which arrangement your filler expects. Our closure selection hub goes further into component fit.
Glass colour by formula
Colour protects the actives, signals where the brand sits and separates the pack from its neighbours on shelf. For some formulas the first of those settles the matter.
| Colour | Light protection | Typical use | Note |
|---|---|---|---|
| Amber | Blocks UV | Serums with vitamin C, retinol or botanical oils | Clinical, pharmacy-style appearance |
| Opal (opaque white) | Blocks light completely | Creams, lotions, luxury lines | Soft matte feel; the fill level cannot be seen |
| Flint (clear) | None | Gel textures, airless systems, formulas meant to be seen | Use when the product itself is the display |
| Cobalt blue | Moderate UV | Night serums and upper-tier lines | The glass costs more |
Amber droppers for actives and opal jars for creams will cover most of a first range. Where the formula contains vitamin C, retinol or most botanical oils, amber is a stability requirement and not a matter of taste. If the formula needs no UV protection, opal or flint may suit the brand better. Have your formulator confirm light sensitivity before the colour is fixed.
Compliance checks and documents
Cosmetic glass holds products that people put on their skin every day, so the paperwork is part of the specification. Ask for it at the start; a supplier unable to provide material certificates should be ruled out for cosmetics.
- Material composition certificate. The glass should be verified for heavy metals and for leachables, the substances that can migrate from glass into an oily formula. Request the leachables test data too.
- Dimensional tolerance report for the finish. Droppers and pumps seal on the surface quality and dimensions of the neck, where tolerances are counted in tenths of a millimetre.
- Seal integrity under your formula. Oils can swell a rubber bulb and alter dropper fit over time, so test closures with the real product.
- Capping torque. When a contractor fills for you, get their torque specification and require a torque test on production batches.
- Market expectations. Glass made offshore should still meet the material expectations that apply to FDA-regulated cosmetics in your market, and that should be documented.
Samples, closure trials and decoration
Three habits keep a cosmetic glass project out of trouble.
- Judge a physical sample. Gram weight, surface polish and the feel of the closure do not show in a rendering or a photograph.
- Trial the closure with your formula. Fill the sample bottle with the actual product, cap it on your own or your filler's equipment and leave it for a week. Seal failures tend to appear within days.
- Bring decoration into the plan early. Frosting, ceramic print and lacquer all interact with the closure and the filling line. Frosting adds surface thickness, so a frosted dropper bottle may need its fit adjusted.
A reference image only conveys visual direction. Details that affect fit should be assessed on a controlled drawing or an approved sample, and final specifications are confirmed in writing for each project. For ranges that pair a cream jar with a fragrance in the same scent family, the finishing questions overlap with those for a custom perfume bottle.
What to put in the brief
We are a sourcing and export-support desk, and we match each project to a suitable partner plant. A complete brief lets us compare stock, modified-stock and fully custom routes separately, with tooling, sampling, components, packing and freight shown as their own lines.
| Area | Record before comparing offers |
|---|---|
| Formula | Viscosity, oil or alcohol content, light sensitivity, compatibility |
| Container | Capacity, shoulder, neck finish, weight, usable label area |
| Component | Pump, dropper, cap, liner, actuator and the fit test required |
| Appearance | Frosting, coating, print, colour, gloss, abrasion standard |
| Approval | Sample set, artwork revision, QC limit, carton, destination |
Add the filling method, the quantity range and any drawing or approved sample you already hold. Published catalogue entries make a useful starting reference, for example the amber dropper bottle series 5572 and the series 5570. A catalogue title establishes the product family and whatever capacity, colour or closure wording it states; dimensions and component compatibility still need a drawing or sample.
Stock droppers, pumps and jars that can be rebranded are listed in the cosmetic glass bottle collection, and other categories sit under all collections. For a dedicated mould, read how custom glass bottle projects run, then send the project brief.
FAQ
What is the minimum order quantity for custom cosmetic bottles?
It is quoted per project for each size, colour and closure combination, and it scales with the cavity count of the mould. Many brands launch on stock-mould glass and keep a dedicated mould for their hero products.
How much does a cosmetic bottle mould cost?
Mould and unit prices are quoted per project. They depend on the mould itself, the decoration, the quantity and the freight terms.
Does a published catalogue page confirm final specifications?
No. It gives a planning reference. Specifications and commercial terms are specific to each project and are confirmed in writing.
What should the first inquiry contain?
The application, target capacity, quantity range and destination, plus any reference image or drawing. Mark the points you need confirmed.
