At QACS we conduct Sensory testing analysis of cosmetics, household and personal care products following standardized international protocols and practices. Sensory experts, trained judges and consumers participate in the assessment of the sensorial characteristics. The sensory perception in terms of smell, aspect, texture, is studied and described for the optimization of new developments. Sensory testing is a powerful tool in product benchmarking.

During a use test, volunteers are recruited to use the product under normal conditions and as specified by the sponsor for a determined period of time. Inclusion criteria that match the target consumer of the product can be chosen from the study sponsor. These studies are conducted under the supervision of a trained clinical professional according to the target area of the product (dermatologist, ophthalmologist, dentist, cosmetologist).

If you wish, we suggest optimal questionnaires to be answered by volunteers by the end and/or during the study.

  • Ophthalmological tests
  • Dermatological tests – Patch and HRIPT tests
  • standard & custom testing protocols
  • pool of more than 1000 volunteers, male or female, aged 18 to 65, covering a wide range of specific characteristics (e.g. sensitive skin, comedones, oily skin, normal skin, dry skin, normal eyes, contact lens wearers etc.)
  • Skin type diversity facilitates all types of cosmetic efficacy testing and enables product claims substantiation
  • Test panel can be customized

Dermatologists and Ophthalmologists provide clinical efficacy testing throughout the evaluation.

At the end of the study, a final report is delivered which includes:

  • Data interpretation and statistical analysis
  • Documented experts opinion
  • Panelists opinion
