Cosmetic Packaging

At QACS we employ suitable analytical techniques adopted to packaging material specifications to serve the most important packaging quality, the preservation of the cosmetic formula. QACS Cosmetic Packaging Testing services detect inert (ceramic, glass) and non-inert materials (paper and cardboard, plastics, rubber, silicone, regenerated cellulose, metals, alloys, bamboo, recycled, active & intelligent and flexible).  We also detect all Container types including films, bottles and colored, non colored, printed and non printed materials.

We initiate Cosmetic Packaging migration tests, with Overall Migration. Overall Migration quantifies the migration of chemical non-volatile substances deriving from packaging without identifying them. 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 food.

So, QACS adapts well-established food contact material test methods to 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. Overall Migration testing findings indicate potential leachables to be analyzed further in the next steps in the process of Packaging Evaluation.

Chemical types migrating from packaging are highly diverse and depend on the packaging material type. Still taking advantage of food contact material regulations we proceed to Specific Migration. With Specific Migration we identify specific substances like monomers or substances of high concern (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 performs migration studies for inert and non-inert materials to 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 the cosmetic packaging. These substances might pose a health risk. To assist in moderating potential health risks QACS performs Non-Intentionally Added Substances (NIAS) screening. We 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 extraction with organic solvents to detect volatile and semi-volatile substances
  • perform multi residual screening to detect organic non-volatile substances

To determine additives and substances deriving from the material article in contact with the active substance we perform 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 for its intended use and evaluate the compatibility between the active cosmetic substance and the packaging material. To examine the interaction between packaging and formulation we proceed to interaction studies, which include migration and sorption studies. Migration studies monitor the leaching of substances from the package material into the formulation and 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 and their data are used to measure the functionality of a packaging material and finally increase the safety of a cosmetic packaging. At QACS we measure Adhesiveness, Elasticity, Hardness, Cohesiveness, Burst strength, Breaking point, Fracturability, Gel strength, Yield point, Consistency and 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 come in contact with food, which examines Food Plastic articles Migration is also taken into consideration.
