Chemical Analysis

The chemical and quality control laboratory at Abich performs tests on raw materials, cosmetic products, medical devices, materials in contact with food, toys, and other consumer products, in line with the Italian, European, and non-EEC countries regulations.

Abich develops tailored research protocols performing interdisciplinary tests like, for example, percutaneous absorption studies in line with the OECD guidelines or stability studies of cosmetic products, medical devices, or pharmaceuticals in line with ICH regulations.

The modern instruments allow to meet customers’ needs thanks to a wide range of validated tests.

Chemical analysis offered by Abich:

  • Instrumental analysis: with HPLC and UHPLC with UV, DAD, RID, FLD detectors;

  • Photostability testing on products with sunscreen: with SUN TEST CPS, title of sunscreens in UV and UHPLC/HPLC before and after irradiation;
  • Chemical Analysis: on toys in line with the UNI EN 71 standard;
  • Migration testing in artificial sweat: to evaluate the release of nickel and other sensitizing metals in products intended to come into direct and prolonged contact with the skin, in line with the UNI EN 1811 standard;
  • Screening of plant extracts: development of an extraction method for scale-up of the manufacturing process;
  • Safety and toxicity evaluation of e-cigarette: on finished products and raw materials components, flavourings, fragrances, while in use and not in use;
  • Suitability of the materials in contact with food: under the Italian Ministerial Decree 21/03/73, the EC Regulation 1935/2004, and their subsequent amendments and supplements;
  • Dynamometric measurement: of the adhesiveness of cosmetic depilatory waxes, depilatory strips, and depilatory plasters.
