In the Mind's Eye: Color Science to Expand the Multicultural Palette

In recent years, the demand for multicultural cosmetics has grown, putting pressure on formulators to extend the shade range of product offerings. The present article reviews the basics of color science, pigments and formulation concepts to support developers for this segment.

Beyond internal efforts toward sustainability are social implications and many suppliers engaged in such efforts were featured at the Sustainability Corner.

[in-cosmetics Global] Social Responsibility, Empowerment and Measuring Up

Perhaps one of the most novel aspects of sustainability presented at in-cosmetics this year was how to measure it.

Soft-focus for the Selfie-obsessed: Eye Tracking to Improve Color Formula Development

In cosmetics, soft focus refers to the blurring of light to immediately correct the appearance of wrinkles and skin imperfections. This parameter can be affected by the refractive index of the emollients used, as well as formula volatility and the dispersion of fillers. The use of eye tracking, described here, can help the formulator quickly select the best-performing formulas.

Tools of the Trade for Sensory Testing

One challenge in manufacturing is the variance in quality of raw materials; another is the mixing process. Mechanical tests, described here in brief, will quickly identify cosmetics and lotions that should be rejected or reworked.

Patent Picks—Wearable, Digitized Skin Care and UV Protection

Patent Picks are compiled by the editors from publicly available sources. This edition features inventions related to digitized skin care.

Formulators Can Avoid Quality Disasters

There are a number of things that cosmetic chemists can do to avoid problems in production and ultimately in the marketplace. In the laboratory, almost anything is possible, but production life is very different.

In Vitro UV Testing—Robot vs. Human Spreading for Repeatable, Reproducible Results

Repeatability and reproducibility are crucial to validate any test method. In order to master these criteria, the authors developed an automated spreading device and compared it with human spreading. Application of the device in eight laboratories and using 36 sunscreens revealed great improvements via automated spreading, ensuring good intra- and inter-laboratory variability.
