Cosmetic Aerosol Tin Can: How SAILON Tests Compatibility and Stability
2026-01-12
Who wouldn’t want a spray cosmetic to dispense smoothly, retain fresh ingredients, and come in a tin can free of corrosion or leakage? As the "close container" for cosmetics, the Cosmetic Aerosol Tin Can’s compatibility with internal formulas and stability during long-term storage directly affect product quality, user experience, and even enterprise compliance. For us focusing on customization services, every batch of high-quality Cosmetic Aerosol Tin Can undergoes a rigorous "nitpicky" testing process before leaving the factory—after all, both the safety bottom line of food-grade Cosmetic Aerosol Tin Can and the adaptation needs of custom Cosmetic Aerosol Tin Can admit no carelessness. This is not only our responsibility to partners but also our commitment to end consumers.
The core logic of testing is simple: simulate the entire lifecycle of the product from production to use, allowing potential issues to surface in advance. We start with compatibility testing. After all, cosmetic formulas vary greatly, with many containing active ingredients like alcohol, fruit acids, and essential oils. Will these ingredients react with tinplate? Will the sealing gasket be dissolved by the formula? These are key questions that corrosion-resistant Cosmetic Aerosol Tin Can must clarify.
In SAILON’s testing laboratory, we fill custom Cosmetic Aerosol Tin Can with different types of cosmetic formulas (water-based, oil-based, alcohol-based, etc.) and let them stand at room temperature for 90 days. During this period, we check weekly for rust or coating peeling inside the cans, while sampling to test if cosmetic ingredients precipitate or discolor. Speaking of which, last year there was a facial mist with high-concentration vitamin C that showed slight oxidation when initially in contact with tin cans with ordinary inner coatings. We immediately adjusted the inner coating formula of the food-grade Cosmetic Aerosol Tin Can, and finally, this custom Cosmetic Aerosol Tin Can passed a 120-day long-term compatibility test.
Stability testing is closer to real usage scenarios. Cosmetics may experience high warehouse temperatures, express cold chains, and being carried around by consumers, and the performance of leak-proof Cosmetic Aerosol Tin Can also needs to be verified under extreme conditions. Referring to the latest 2024 industry standards, we designed multi-dimensional testing items as follows:
| Test Item | Basic Industry Standard | SAILON's Practical Requirements | Test Cycle |
|---|---|---|---|
| High-Low Temperature Cycle Test | 3 cycles of -10℃~45℃ | 5 cycles of -15℃~50℃ (simulating extreme transportation) | 14 days |
| Long-Term Storage Simulation | 6-month storage at 25℃ | 8-month storage at 25℃ + 60% humidity (constant temperature and humidity) | 8 months |
| Compression and Leakage Test | Withstand 50kPa without leakage | Withstand 80kPa for 24 consecutive hours without leakage (adapting to leak-proof Cosmetic Aerosol Tin Can standards) | 24 hours |
| Corrosion Resistance Test | 24-hour salt spray test without rust | Dual test: 48-hour salt spray + formula immersion (meeting corrosion-resistant Cosmetic Aerosol Tin Can requirements) | 48 hours + 90 days |
Is it enough to just pass these standardized tests? Actually, we also add some "unconventional" tests for custom Cosmetic Aerosol Tin Can based on different usage scenarios. For example, simulating consumers' frequent pressing of the nozzle, we conduct a sealing performance test after 1,000 consecutive presses on the can. For sunscreen sprays used outdoors, we add an extra UV irradiation test to ensure the coating of high-quality Cosmetic Aerosol Tin Can won’t fade or crack.
For partners, the biggest concern is the match between test results and practical applications. Here are two frequently asked questions, sharing our practical experience:
Q: Do test parameters need to be adjusted for custom Cosmetic Aerosol Tin Can with different cosmetic formulas? A: Absolutely. For example, for perfume sprays with high volatile ingredients, we shorten the interval of high-low temperature cycles and focus on testing the anti-volatility of the sealing parts of leak-proof Cosmetic Aerosol Tin Can. For cream-textured cosmetics, we add an inverted storage test to avoid uneven contact caused by ingredient precipitation, which is also a basic adaptation requirement for food-grade Cosmetic Aerosol Tin Can.
Q: How long is the actual shelf life of Cosmetic Aerosol Tin Can that pass the test? A: Under proper storage conditions, high-quality Cosmetic Aerosol Tin Can that pass our full set of tests usually have a shelf life of 2-3 years. However, this is not absolute—after all, the shelf life of the cosmetic formula itself will also affect the overall usage cycle. We recommend partners clearly mark the combined shelf life on product packaging, especially for products using corrosion-resistant Cosmetic Aerosol Tin Can to hold highly active ingredients.
In SAILON’s more than ten years of customization services, these testing standards have been integrated into the production process of every batch of Cosmetic Aerosol Tin Can. We have always believed that testing is not a "formality" but a way to avoid risks at the source. A high-quality Cosmetic Aerosol Tin Can that can withstand various environmental tests and perfectly match the formula can truly retain the effectiveness of cosmetics and enhance the brand reputation of enterprises. Whether it’s the safety red line of food-grade Cosmetic Aerosol Tin Can or the personalized needs of custom Cosmetic Aerosol Tin Can, the testing link is a bottom line we dare not slack off.
