Cosmetic Packaging Compatibility Testing

QACS provides Laboratory Testing services to check Packaging Compatibility. Packaging Compatibility testing services detect inert (ceramic, glass, steel) and non-inert materials (paper and cardboard, plastics, rubber, silicones, regenerated cellulose, metals, alloys, bamboo, recycled, active, intelligent and flexible). Migrant detection outside the packaging such as colored, noncolored, printed and nonprinted materials is also provided.

Cosmetic Packaging testing services from QACS:

  • are adopted to packaging material specifications
  • serve the most important packaging quality, the preservation of the cosmetic formula
  • ensure regulatory compliance and product safety
  • are offered to all Packaging types, coating types and all container types including films, bottles and bags

Overall migration tests quantify chemical non-volatile substances migrating from the packaging into cosmetics (10 mg per dm² limit). Test findings indicate potential leachables to be further analyzed in the next steps of the Packaging Compatibility process. QACS Labs follow Commission Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with cosmetic formulas.

A and D2 simulants are frequently used and respectively represent hydrophilic or lipophilic types of cosmetic formulas. In order to estimate time and temperature (contact conditions) between simulant and cosmetic packaging, we take the product’s expiry date into account.

QACS Labs identify diverse chemical types for inert and non-inert materials such as Phthalates, PAHs, Bisphenol A, Melamine, Acetaldehyde, plastic Additives, Formaldehyde, Fluorescent whitening agents, Benzophenone, glyoxal, Pentachlophenol, Heavy Metals and various Monomers.

>Chemical types migrating from packaging are highly diverse and depend on the packaging material type. We identify SVHC established by EFSA on the basis of toxicity data from each specific substance. If the material is unknown, it is necessary to identify it by FTIR spectroscopy.

SM is measured by leachables migrating after appropriate extraction. Each substance has a different migration limit deriving from its toxicity measurement. Stability studies are closely connected with Packaging Compatibility, due to the significance of migration findings from exposure assessment.

With NIAS screening we

  • detect organic volatile substances, which can cause possible organoleptic modifications in the formulation
  • perform organic solvent  extractions to detect volatile and semi-volatile substances
  • perform multi residual screening to detect organic non-volatile substances

NIAS screening e.g. Non-Intentionally Added Substances detects and quantifies impurities derived from manufacturing, extraction, storage and recycling processes. NIAS screening also detects substances completely unknown, reaction products and degradation products.

Substances not listed in the Commission Regulation (EU) No 10/2011 on plastic materials need to be risk assessed.

Extractables studies identify derived Additives & substances from material articles. To increase the rate of extraction, we expose the material sample to an appropriate solvent system under stress conditions. Solvents used in QACS Extractables studies have the same propensity to extract substances as the active substance in the cosmetic formulation.

Leachables studies determine packaging material suitability for intended use. Interaction studies examine packaging and formulation impact and include migration and sorption studies. Migration studies monitor the leaching of substances from the package material into the formulation. Sorption studies evaluate possible loss of cosmetic qualities due to adsorption or absorption effects.

Changes in mechanical properties could provoke alterations in packaging performance. Cosmetic packaging materials can undergo mechanical testing both before and after stability studies in order to verify possible changes in mechanical properties throughout all stages of the cosmetic formulation. To increase cosmetic packaging safety we perform:

  • Barrier tests to indicate the permeability of gases and evaluate the quality of packaged cosmetics.
  • Tensile strength tests to determine the maximum load to be applied on a packaging material before its breakage or disintegration point.

At QACS we measure functional properties which affect packaging performance. These are Adhesiveness, Elasticity, Hardness, Cohesiveness, Burst strength, Breaking point, Fracturability, Gel strength, Yield strength, Consistency & Relaxation.

Data from functional properties testing on cosmetic packaging is used to measure packaging material functionality in order to substantiate cosmetic package claiming.

As indicated in Cosmetic Packaging testing, QACS follows the general safety and inertness principles from the harmonized framework on all packaging materials (EC) No 1935/2004 on Food Contact Materials which states general safety requirements. The most comprehensive specific EU measure, EU No 10/2011, is also taken into consideration.
