Dropper Assemblies for Nutraceutical, Herbal, Cosmetic, and Pharmaceutical Products
Different industries require different dropper materials, tolerances, and assembly designs. RTN Applicator supplies dropper assemblies for a wide range of packaging applications.
Nutraceutical Dropper Assemblies
Liquid supplements, vitamins, and botanical extracts often contain alcohol or active ingredients that require chemically compatible dropper bulbs and pipettes.
Herbal and Tincture Droppers
Tincture products commonly use alcohol-based formulations that can damage low-quality bulbs. Proper material selection is critical for long-term reliability.
Cosmetic and Skincare Droppers
Cosmetic droppers must provide smooth dispensing, consistent appearance, and compatibility with oils, serums, and active ingredients.
Pharmaceutical Dropper Assemblies
Medical packaging requires precise tolerances, consistent dosing, and reliable sealing. Dropper assemblies must meet strict quality requirements.

Dropper bulb
Dropper Bulb Materials and Chemical Compatibility
Selecting the correct dropper bulb material is one of the most important factors in dropper assembly performance. Different liquids can cause swelling, cracking, or loss of elasticity if the wrong material is used.
RTN Applicator manufactures dropper bulbs using materials such as:
• TPE (thermoplastic elastomer)
• Medalist
• Monprene
• Specialty elastomer compounds
TPE dropper bulbs, including Medalist® formulations, provide improved resistance to alcohol, essential oils, and aggressive formulations compared to traditional silicone in many applications.
Material selection depends on:
• Alcohol content
• Oil content
• Solvents
• Extract strength
• Required compression force
• Storage conditions
