Our panel consists of ten expert evaluators who engage in daily training, the better to translate their sensory perceptions into quantitative sensorial information.

The evaluations are carried out through comparisons with benchmarks in order to classify the products. If the goal is to identify an alternative, the comparison is made in relation to a reference formulation containing the benchmark.

Consequently, each evaluator is able to give a precise, reproducible characterization of our esters as well as the benchmarks.

On a more detailed level, each product is evaluated in two phases according to clearly defined descriptors and protocols. During application, the criteria to be evaluated are Initial perception, Texture, Melting, Spreadability, Roughness and Penetration.

After application, the evaluation comprises Smooth finish, Greasy finish, Sticky finish, Glossy finish and Residual film.

Each descriptor is evaluated on a scale of 0 to 10, with 0 indicating that the analysis criterion is absent and 10 indicating that the criterion is strongly present.

Our panel’s specialization in glycerides has enabled us to define the sensory profiles of about 150 esters and some 15 benchmarks, including silicones, vegetable oils and other petroleum derivatives.

The global trend on the cosmetics market calls for the substitution of petroleum products in formulation. That is why Stearinerie Dubois, in keeping with its commitment to green chemistry and respect for nature, has undertaken this study, relying on its scientific and sensory expertise.
