The use of model samples in the process of selection of sensory panel to assess cosmetic products

The article discusses an innovative approach to the formation of a sensory panel formed for the purpose of evaluating cosmetic products. Model samples of cosmetic emulsions are proposed, which should help in the initial selection and training of sensory panelists, in order to improve the precision of evaluations. Simple and easily reproducible emulsions (comprising rapeseed oil, sunflower lecithin, water, and xanthan gum) were formulated to represent a specific level of variability associated with a particular property, such as thickness. To confirm that the ability to rank the produced emulsions can be considered a criterion for selecting individuals for the sensory panel—resulting in greater consistency of results—tests involving moisturizing creams were conducted. The study's findings demonstrate that the novel approach to candidate selection, through the assessment of model emulsion consistency, is both effective and justified. This method has the potential to enhance recruitment efficiency by identifying individuals with a high ability to evaluate cosmetic emulsions.

Practical Applications

Those who benefit from the work include professionals and researchers dedicated to enhancing sensory panel selection processes. The main goal was to optimize the sensory panel selection and training process. Reference samples help determine whether potential members have the right skills and potential for sensory evaluation. Selecting individuals with a greater aptitude for assessments based on the sense of touch can be particularly valuable for companies operating in industries where the sensory quality of products is important.
