Skin Lab International offers full qualitative analysis of products (cosmetics/household chemicals and others). We also offer an extremely wide range of physicochemical tests of cosmetics, including:
- organoleptic evaluation (appearance, colour, smell, consistency)
- pH determination (both directly in the formulation and from an aqueous extract)
- measurement of density,
- viscosity determination,
- determination of stability (density measurement, centrifuge test, temperature test),
- measurement of foaming capacity,
- control of tightness and durability of packaging,
- and other tests carried out on customers' request.
What is more, we also offer PAO tests with shelf-life indication (3M, 6M, 12M, 24M, 36M). We also carry out PAO testing for perfumery products and compatibility and sealability testing for aerosol products.
Skin Lab Int. also offers specialised physicochemical testing dedicated to pressed products (powders, eye shadows, etc.) – testing of hardness of sintered products. The laboratory can also determine the hardness/fragility of lipsticks and sticks. Tests are conducted using a texturometer. Moreover, for colour cosmetics, we perform spectrophotometric measurement of product colour (spectrophotometric study), as well as determination of heavy metal residues (ICPAES method). We determine: iron, chromium, cadmium, antimony, lead, arsenic and nickel.
