Summary
Developing a trained sensory panel for lipstick evaluation is crucial. Rigorous screening and training ensure reliable product analysis, leading to consistent and sensitive sensory data for cosmetic development.
Area of Science:
- Cosmetic Science
- Sensory Analysis
- Product Development
Background:
- Sensory analysis is vital for evaluating cosmetic products like lipstick.
- Developing a trained sensory panel requires careful selection and rigorous training protocols.
Purpose of the Study:
- To establish a reliable and sensitive trained sensory panel for lipstick evaluation.
- To develop standardized sensory language and a scoring system for lipstick attributes.
Main Methods:
- Recruitment and screening of female lipstick users using the duo-trio method.
- Development of sensory attributes (e.g., Spreadability, Hardness, Glossy) through iterative sessions.
- Training sessions focused on defining attributes and consistent scoring.
Main Results:
- Approximately 60% of initially recruited panels met the screening criteria.
- A working group of nine panels developed a consensus on eight sensory attributes.
- Analysis of variance confirmed panel performance and reliability.
Conclusions:
- A structured panel selection and training process yields a reliable and sensitive trained panel.
- The developed sensory language and scoring system enable consistent lipstick evaluation.
- This methodology supports objective product assessment in cosmetic research.

01:16Sensory Functions of the Skin
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:43Gustation
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.
01:27Synesthesia
Synesthesia is a remarkable condition where stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. People with synesthesia experience a blending or crossing of their senses, such as sight and sound, leading to cross-modal sensations. In this condition, the stimulation of one sense, such as hearing a number or musical note, triggers an experience of another sense, like sensing a specific color, taste, or smell. People...
01:26Introduction to Special Senses
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive functions.
01:11Sensory Perception: Organization of the Somatosensory System
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...
