Package-Product Interaction Services for Cosmetic Development Partners
What is Package-product interaction?
Package-product interaction testing evaluates how your cosmetic formula behaves with its container over time. Labs test for chemical migration, color changes, and material degradation by storing products in their final packaging under different conditions—typically 40°C for three months to simulate shelf life. This prevents product recalls by catching issues like plastic containers leaching into serums or metal tubes reacting with acidic formulas before market launch.
Why do you need this service?
Cosmetic labs conduct accelerated stability testing to predict how your serum reacts with glass droppers or how cream formulas interact with airless pumps over 24 months. Labs simulate real-world conditions—testing pH shifts, color changes, and active ingredient degradation when products contact different packaging materials, helping you avoid costly recalls and reformulations before launch.

Package-Product Interaction Testing
Package-product interaction testing determines how your cosmetic formula reacts with its container over time. Labs on our platform test whether your serum degrades plastic bottles or if metal tubes affect your cream’s stability—protecting both product quality and brand reputation.
Material Compatibility Analysis
Testing labs evaluate how different packaging materials interact with your specific formula. They check glass, plastic, aluminum, and composite materials for chemical reactions, color changes, and structural integrity.
- Leaching tests detect if packaging chemicals migrate into products
- pH stability monitoring tracks formula changes over 3-6 months
- Accelerated aging studies predict 2-year shelf life in 8 weeks
- Barrier property testing measures oxygen and moisture transmission
Results help you select packaging that preserves active ingredients and maintains product performance throughout shelf life.
Functional Performance Testing
Beyond chemical compatibility, labs test how packaging performs during real-world use. They evaluate pump mechanisms with viscous formulas, check dropper accuracy with serums, and test tube squeeze consistency.
- Dispensing tests measure dose accuracy across 500+ uses
- Drop testing simulates shipping and handling impacts
- Temperature cycling (-20°C to 50°C) reveals seal integrity
- Microbiological challenge tests confirm preservative effectiveness
These tests prevent customer complaints about clogged pumps, leaking containers, or inconsistent product delivery. Labs provide detailed reports showing which packaging options work best for your specific formula type and target market.
Real-World Applications of Package-Product Compatibility Testing
Package-product interaction testing directly impacts product shelf life, consumer safety, and brand reputation by identifying potential chemical reactions between formulations and their containers.
Stability Testing for New Product Launches
Labs evaluate how cosmetic formulations interact with different packaging materials during accelerated aging tests. Active ingredients in serums and creams can react with plastic containers, causing discoloration or degradation within 3-6 months.
Testing protocols include migration analysis to detect leaching of plasticizers, UV stabilizers, and other additives from packaging into products. Labs use gas chromatography and mass spectrometry to quantify these interactions at parts-per-million levels.
Material Selection for Sustainable Packaging
Compatibility testing helps brands transition to eco-friendly packaging without compromising product integrity. Labs test PCR (post-consumer recycled) plastics, biodegradable polymers, and refillable systems against specific formulation types.
| Packaging Material | Common Incompatibilities | Testing Duration |
|---|---|---|
| PCR Plastics | Essential oil absorption, color migration | 12-16 weeks |
| Aluminum Containers | pH-sensitive formulas, water-based serums | 8-10 weeks |
| Glass with Rubber Seals | Volatile fragrances, alcohol-based products | 6-8 weeks |
Results guide packaging engineers in selecting barrier coatings, closure systems, and material grades that preserve product performance throughout the intended shelf life. Contact specialized labs on our platform to develop custom testing protocols for your unique formulation-package combinations.
