Course Description:

Introduction to Sensory Characterization of Cosmetic Emulsions
Thursday, October 10, 2019  (9:00am-5:00pm)

Newark Liberty International Airport Marriott
1 Hotel Road, Newark, NJ 07114


The sales potential of cosmetic products is greatly determined by skin feel and skin sensory performance. To please the target audience, it is important to gather information about consumers’ perception of products’ sensory characteristics. Sensory characteristics, including appearance, rub-out, pick-up, and afterfeel, can help build an emotional relationship with the consumer, trigger excitement, and help consumers purchase the product again and again, which is the primary goal of developing products.

In this one day, interactive course, participants will learn about the various types of sensory testing available in the cosmetic industry, their advantages and drawbacks. Later in the day, participants will have the chance to design a product based on a product brief and then
do a sensory analysis on the product.


Who Should Attend:

This course will be useful for scientists, sales people and cosmetic marketers alike. This includes formulators, quality control chemists, and product development professionals. Raw material sales people will also benefit from learning about sensory testing. 


Course Outline:

Importance of texture and sensory testing basics – in this section participants will learn about why texture and skin feel are important for consumers. Additionally, participants will learn about the various ways of how product aesthetics can be tested and how a sensory testing should be designed. 

  • Importance of texture and sensory characteristics for cosmetic emulsions
  • Human senses from the perspective of sensory analysis – vision, touch, smell, taste and sound
  • How to measure aesthetics? – instrumental measurements vs sensory analysis
  • Sensory test methods for preferences vs. differences – affective vs. analytical methods
  • Tips for selecting the right sensory test method for a product
  • Variables to consider when designing a sensory evaluation test – panel, product, test room

An innovative approach to getting an insight into consumer preferences – in this section, participants will learn about an innovative sensory testing method, the instructors will share a case study.

  • CATA survey for the sensory characterization of emulsions using untrained consumers
  • Study objective, setup, test
  • Results and main conclusions

Hands-on session – participants will have the opportunity to experience a rapid product development session. Participants working in groups will select a product based on their demographics, design the color, fragrance and packaging of the product and do a sensory analysis on the product.

  • Selection of emulsions for a defined purpose, completing three different surveys for each emulsion
  • Designing color and fragrance and selecting packaging
  • Discussion about survey results
