Cosmetics are used for skin care and for decorative purposes. Nowadays, they have become almost as important for men as for women. Cosmetics include skincare creams and makeup such as lipsticks, eye shadow, nail polishes and hair sprays.
Thermal analysis methods are used for studying raw materials as well as for developing and checking the quality of the final cosmetic products. The different methods are ideal for characterizing cosmetics and their ingredients.
In this Webinar, we will show how thermal analysis is used to analyze cosmetic materials and present typical examples of samples measured by DSC, TGA, TMA as well as by dropping point and melting point instruments.
The webinar titled "Thermal Analysis of Cosmetics" presents relevant applications for the characterization of cosmetic products and preparations as a function of temperature.
Cosmetics include all sorts of substances that are applied to different parts of the human body for enhancing people’s appearance, for skin-, hair- and nail-care, and for cleansing purposes.
This webinar presents a number of interesting application examples that demonstrate the use of thermal analysis techniques in the cosmetics industry. The applications have to do with the measurement of the physical properties and behavior of cosmetic preparations as a function of temperature and include melting, content determination, denaturation studies, curing reactions, and loss on drying.
The most important effects that can be analyzed by DSC are the melting point, melting range, and melting behavior.
For TGA, the main applications are evaporation, content determination and filler determination.
A Dropping Point or DP instrument is used to detect the dropping point of waxes.
A Melting Point or MP instrument is used for automatic melting point determination and melting range detection.
TMA is normally used to study the expansion or shrinkage of materials.
