Packaging testing services ensure regulatory compliance and product safety. QACS’s analytical techniques are adopted to packaging material specifications and serve the most important packaging quality, the preservation of the cosmetic formula.

QACS 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) for all Packaging types, coating types and all container types including films, bottles and bags.

Migrant detection outside the packaging such as colored, noncolored, printed and nonprinted materials is provided.

As suggested in Cosmetic Packaging testing, QACS follows Commission Regulation (EU) No 10/2011 on plastic materials and articles intended to come in contact with cosmetic formulas. Overall migration tests quantify chemical non-volatile substances migration, derived from packaging. Overall Migration testing findings indicate potential leachables to be analyzed further in the next steps in the process of Packaging Evaluation.

Well-established contact material test methods estimate the total amount of non-volatile substances migrating into cosmetics (10 mg per dm² limit). A and D2 simulants are frequently used and to respectively represent hydrophilic or lipophilic types of cosmetic formulas. In order to estimate time and temperature (contact conditions) between simulant and cosmetic packaging, the product’s expiry date should be taken into account.

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

QACS migration studies for inert and non-inert materials detect for Phthalates, PAHs, Bisphenol A, Melamine, Acetaldehyde, plastic Additives, Formaldehyde, fluorescent whitening agents, benzophenone, glyoxal, pentachlophenol, Heavy Metals etc and various Monomers.

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

Manufacturing, extraction, storage and recycling processes cause substances or ingredients to exist in cosmetic packaging. Such substances might pose a health risk. NIAS screening e.g. Non-Intentionally Added Substances detect and quantify impurities, 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.

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

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

Leachables studies determine the suitability of a packaging material suitability for it’s 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 of packaging performance. To increase the safety of cosmetic packaging and cosmetic formulation we perform barrier tests and tensile tests. Barrier tests indicate the permeability of gases and evaluate the quality of packaged cosmetics. Tensile strength tests are applied on all kinds of packaging materials and determine the maximum load to be applied on a packaging material before its breakage or disintegration. Cosmetic packaging materials can undergo a mechanical testing both before and after stability to verify possible changes in mechanical properties in all stages of the cosmetic formulation.

Cosmetic Packaging functional properties affect packaging performance. Data are used to measure packaging material functionality and increase cosmetic packaging claiming.

At QACS we measure Adhesiveness, Elasticity, Hardness, Cohesiveness, Burst strength, Breaking point, Fracturability, Gel strength, Yield strength, Consistency & Relaxation.

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 is EU No 10/2011 on plastic materials and articles intended to contact food is also taken into consideration.
