Color measurement of pasty and semi-solid pharmaceutical products

In the pharmaceutical industry, the precise determination of the color of medically active products such as ointments, creams, pastes and gels is crucial in development and quality management. Color change is often associated with aging and loss of effectiveness. With other pasty or semi-solid medicines, the color is used as a characteristic feature of certain products in order to convey consistent quality to the customer and thus confidence in the effect.

Color plays an equally important role in the cosmetics industry. Decorative cosmetics and care products only inspire consumer confidence if they have a consistent appearance. Products such as creams, lotions, make-up and shower gels can be translucent or opaque. HunterLab spectrophotometers meet both requirements.

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
