Sensory analysis for topical drugs
Poor adherence to topical treatment is a serious problem with several contributing factors. Numerous studies have shown that poor texture and sensorial properties negatively impact patient experience and adherence to treatment. Sensory analysis will help you developing innovative topical formulations, taking into consideration patient’s experience of texture and sensorial properties.
A tool to formulate patient-friendly textures
Sensory analysis is a scientific discipline that applies the principles of experimental design and statistical analysis to measure, analyze, and interpret the characteristics of a product as they are perceived by the senses.
Gattefossé has developed validated methods and established an in-house trained panel. Using this approach, we can evaluate the sensorial properties of prototype formulations to:
- assess the influence of raw materials in the formulation,
- evaluate the main texture characteristics of our excipients,
- compare prototypes with market references,
- understand market preferences,
- construct a broad texture database,
- and help our customers develop their own formulations.
A trained panel and validated methods for reliable results
Our sensory panel brings together over a dozen trained staff members, both men and women. They test new formulations approximately twice a week. The assessments are carried out using specific protocols and standardized procedures, and the results are statistically analyzed.
Tests cover vision and touch, and they evaluate the following criteria:
Appearance |
Immediate contact |
Upon application |

The power of sensory mapping
This sensory map shows the results with cream formulations formulated with different Gattefossé pharmaceutical-grade emulsifiers. It enables direct and visual comparison and can help to select the emulsifier or appropriate prototype formulation.
