A Novel Method to Measure and Pre-select Functional Filler Pigments

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.

Evaluating Hair Conditioning with Instrumental Combing

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.

Benchmarking Study to Examine Shampoo, Conditioner Rinse Profiles

TRI/Princeton is offering a benchmarking study on the rinsing of shampoos and conditioners to allow manufacturers a lower cost option for product testing, as compared with individual tests.

Evaluating the Physiochemical Properties of Emollient Esters for Cosmetic Use

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.

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.

Falling Ball Viscometer for Newtonian Fluid Measurement

Brookfield Engineering celebrates its 75th anniversary with the introduction of the Falling Ball Viscometer, an instrument to assess the dynamic viscosity of transparent Newtonian fluids.

A Dermatological View: Tandem Irritants With Synergistic, Additive or Quenching Effects on the Skin

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.

Using Consumers’ Sensory Experience to Achieve Strategic Market Segmentation

Used in conjunction with marketing and marketing research techniques, consumer-based sensory evaluation techniques provide an effective business strategy for product development and brand management.

In Sight--Extrasensory Perception in Product Development

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.

Rheology and Texture Analysis Used Together to Improve Raw Material Choices

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.

Quality Comparison of W/O and O/W Photo-Protection Creams

The authors determined the quality of a photoprotector W/O cream by evaluating its microbial control, physicalchemical stability and sensory appeal in comparison to an O/W photo-protector cream.
