Calling All Chemists, Formulators and Researchers

Are you sitting on a research “gold mine”? Get your work published! Cosmetics & Toiletries magazine is interested in your research as it pertains to cosmetics and personal care R&D.

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.

R&D Awards Finalists Announced

Cosmetics & Toiletries magazine has announced the finalists for its 2011 R&D Awards, which will honor one new ingredient for its design and one finished product for the craft of its formulation. Winners will be announced at In-Cosmetics in Milan.

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.

Fluorescence Laser Scanning Confocal Microscopy to Assess the Penetration of Low Molecular Protein Hydrolyzates Into Hair

The present study uses confocal laser scanning fluorescence microscopy to assess the penetration of protein hydrolyzates into hair. While higher amounts of protein were found in the cuticle, still significant quantities were observed in the cortical parts of hair, and this penetration was enhanced by longer incubation times.

TRI/Princeton Forms Group to Advance Measurement Techniques

TRI/Princeton announced it has formed a Measurement Service and Claims Support group to expand its personal care product performance and claims support test methods with new measurement techniques.

The VS450 is X-Rite's response to customers in the cosmetics industry that are looking for lab-to-production solutions.

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.

Much Ado About Nothing: Cosmetics Testing with a Placebo

In this column, the author investigates the source of the placebo effect. In addition, he asks the question: Must cosmetics testing always incorporate tests against a placebo?

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.

Quantifying Skin Relaxation and Well-Being

Skin relaxation and well-being can be measured by quantitative methods, and modulated by a Tyr-Arg neuropeptide used in topical cosmetic preparations.

How Sensory Evaluation Can Provide Development Direction: An Approach

The authors explain how linking product sensory attribute documentation, through descriptive analysis panels, with consumer exploration through one-onone interviews, provides clear direction to product development. In addition it permits the product development team to track progress of the prototypes.

Skin Friction Coefficient Values

Friction is an important characteristic of skin because it allows us to execute many of our daily activities. In addition, friction studies offer insight into how skin and the skin surface change across age, gender, race, anatomical site, and chemical applications. This can provide better information about expected skin variations in the population and why certain topical applications are effective.

Sensory Congress Announced for Summer 2009

The congress will gather scientists and professionals to explore new paths open to the perfume and cosmetics business through novel research carried out on the senses.
