Functional filler pigments play an important role in adjusting optical properties such as transparency and soft focus effects in cosmetics. However, their suitability for specific formulas is not apparent until time-consuming tests using many different fillers have been conducted. Therefore, a new method to predetermine the soft focus effects of functional filler pigments is described here.

When formulating a hair care product, there is often a need for testing that validates the product’s technical performance. This testing provides guidance to create formulas with appropriate performance, while also communicating the product’s message to the consumer. This article discusses the use of instrumental combing measurements when formulating hair conditioning products.

This study assesses the physicochemical properties of four known cosmetic emollient esters in vitro to predict their sensorial benefits and correlate their properties with in vivo sensory attributes. This evaluation serves as a guide to selecting specific emollient esters for various cosmetic applications and to predicting their sensory attributes.

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.

In this article the results of six published tandem irritation studies are evaluated; possible mechanisms and clinical ramifications, albeit complex, are discussed. The clinical relevance of tandem irritation among cosmetics users and in many occupational settings appears obvious and suggests the need for further studies clarifying its principles and mechanisms.

Through his experience of working with consumers, Avery N. Gilbert, president of Synesthetics Inc., has discovered that the challenge is not so much discovering what consumers want as interpreting what they think they want.
Correlation of Long-term Physical Stability of Emulsions with the Short-term Rheological Measurements

Three short-term rheological measurements on some model personal care emulsions showed good correlation with long-term physical instability of the emulsions. Use of these rheological measurements can shorten the time to test the stability of new formulations.

SEPPIC has developed rheology and texture analysis protocols that, when used in combination, provide useful data regarding the impact of raw material choice on all the development steps: manufacturing procedure, formulation stability, skin feeling.
