Droppers

What are Cosmetic Droppers?

A cosmetic dropper is a closure-and-bottle system that dispenses low-viscosity skincare one drop at a time. It pairs a bottle - glass or PET in the verified range - with a dropper assembly whose pipette draws and releases a metered dose: 0.15-0.17 ml per squeeze, with a 0.23 ± 0.02 ml variant. Dose is governed by pipette volume and squeeze action; dip-tube immersion keeps each intake consistent.

Formulation Compatibility & Applications

• Compatible Formulations: Low-viscosity serums, facial oils, treatment drops, essence and thin emulsions that flow readily through a pipette.
• Target Packaging Use Cases: Serum dropper bottles, facial oil packaging, treatment ampoules-style droppers, and small-capacity premium skincare where drop-level precision is required.

Engineering Materials & Sustainable Options

• Verified Materials: Bottle bodies in glass and PET confirmed in the dropper range; PP-based dropper assemblies are family-level norm. Gaskets and seals are sourced as purchased components.
• Eco-Friendly & PCR Solutions: PCR PP, PCR PET and PCR PETG capabilities apply to dropper packaging on a project basis. Glass bottles are available in the dropper range; recycled-content percentage is project-specific and confirmed against specification.

Customization & Secondary Processing

Dropper closures and bottles accept screen printing, pad printing, UV printing, heat transfer printing and hot stamping, plus spraying/coating for soft-touch or glossy surfaces. Pipette style, cap color and bottle shape are customizable. Review customization capabilities and quality-control validation before specification.

Procurement FAQ

Q1: Which neck finishes are available for droppers?

A1: The catalog covers 18/410, 18/400, 20/410, 20/415, 20/400, 24/410 and 16/410. The dominant finishes are 18/410, 20/410 and 24/410. Body and collar are specified to match the bottle neck and dip-tube length.

Q2: How is dropper leakage and dose accuracy validated?

A2: Leakage and vacuum tests verify seal integrity, drop tests confirm transit robustness, and dosage/output tests measure delivered volume per squeeze (0.15-0.17 ml and 0.23 ± 0.02 ml targets). All are part of the 12-category laboratory testing scope, with pass criteria per project spec.

Q3: What are sampling and packaging lead times for droppers?

A3: Samples are produced through SLA 3D printing and prototype development; tooling is developed in-house before mass production. MOQ and lead time are quoted by bottle material, capacity, neck finish and decoration - confirmed against the project specification.
