Preservative Predicaments in Facial Skin Care
Preserving skin care products has become challenging because of attacks by special interest groups, which often lead to negative consumer perceptions. As these assaults on preservatives—some scientifically sound, some not—continue, the industry must look for new preservation methods to gain acceptance.

Predicting the Percutaneous Penetration of Cosmetic Ingredients
While previous algorithms for predicting the skin absorption of permeants was based on in vitro data, the present article proposes a quantitative structure-activity relationship (QSAR) model based on in vivo human data. Here, a set of human in vivo data is described that provides entry into predicting the penetration of cosmetic ingredients.

Editor’s Note: Consumer Predictors
This issue of
Cosmetics & Toiletries
nicely fits the market predictors of well-being, value/quality, technology and eco/surroundings for 2021. It explores monk fruit for well aging, positive emotions and a healthy glow; transfer-proof cosmetics; litchi peel for skin brightening; playful and engaging product textures; and a diagnostic tool to marry heredity with lifestyle for product customization; among others. Read on to learn more.

Patent Pick: Growing 3D Skin Predictions
A product manufacturer's reputation is perhaps its greatest asset, and growing numbers of cosmetic consumers with sensitive skin only raise the product development bar. That's where patented inventions such as this, a 3D skin model, can ensure product safety and support cosmetovigilance initiatives.

Zeta Potential and Particle Size to Predict Emulsion Stability
Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.

Tools to Predict, Assess and Standardize Successful Color Cosmetics
Cosmetic companies have borrowed quality control methods from other industries that have product attributes such as color, gloss and texture down to a science. Specialized in such areas, X-Rite has developed tools to enable cosmetic companies to predict future color trends as well as set standards by which future cosmetics will be benchmarked.

Quantifying Well Aging: A Mathematical Sketch to Predict Age
There is no biological evidence to explain why some individuals look older or younger than they really are. This work sought to quantify the cutaneous characteristics of well aging based on focus group input, word clouds, biometric measurements and more.

A High Throughput Method to Predict Skin Penetration and Screen Topical Formulations
This work studies the applicability of a 96-well-based skin-mimetic artificial membrane permeability model to differentiate between topical pharmaceutical and cosmetic formulations. Results are compared with data obtained from in vitro Franz cell permeability measurements and reveal the applicability of this method to assess cosmetic formulation permeation and speed the discovery process.

A Dermatological View—Squamometry: An Early Predictor of Changes in the Skin Barrier
Squamometry is useful in identifying the low or subclinical irritation potential of substances even before any change in the TEWL can be measured.
