Custom Analysis Organization

A complete testing strategy

Ironclad security of results, quick execution time and cost-effectiveness, these are the primary reasons that drive our customers to rely on us.

The importance of an optimal testing strategy

Our laboratories carry outCustom Made testing strategies specifically created around the peculiarities and needs of each individual tested product.

Testing on volunteers only as confirmation of in vitro tests

Volunteer testing is only used as a confirmation of the safety and effectiveness resultsobtained by the in vitro tests in the testing strategy.

This allows us to reduce the riskfor volunteers compared to other practices established in the industry.

Our strategies

The eye is an extremely delicate organ.

Cosmetic products that may come into contact with it must be thoroughly evaluated, from a safety standpoint, by the Safety Assessor.

The testing of possible dermal irritation caused by a cosmetic product, among the evidence that the Company must produce for its Product Information File, is of fundamental importance.

Ethical models, new tests

INT.E.G.RA. is dedicated to the research, development and validation of in vitro tests to determine the beneficial effects of cosmetics: rejuvenating, healing and antioxidants.

Evaluation of the maintenance over time of the prerogatives of the product for the use for which it was formulated.

Stress conditions: in thermostat (45°C); in refrigerator ( 2-4°C); at room temperature (25°C).

Main phenomena evaluated: Creaming; Flocculation; Coalescence; Phase inversion; Packaging deformation.

Other analylses available on request: pH measurement; Viscosity measurement; Light stability; Thermal shock.

The analysis has a duration of at least one month with deadlines distributed over time.

The method is based on the determination of the D value, defined as the time, expressed in hours, necessary to reduce the inoculated mycorbic charge by 1 logarithm (90%).

The inoculum is made of multiple microbial strains, gram positive, gram negative, yeast and mold, as in a classic challenge test. the D value is then corrected according to an index given by the sum of two factors: the type of packaging in which the product is packaged and the type of use expected for the product.

This variation of the method also makes it possible to judge the shelf life of the product after it has been opened and during use, to suggest suitable packaging or instructions for use and appropriate post-opening expiry dates based on the specific D values found.

Samples Required: 1 sample of 150 ml + INCI Run time: 3 days per inoculum 28 days incubation 3 days for reading.

Patch test on volunteers.
