Malvern Instuments has launched a device suitable for the characterization of proteins and nanoparticles where the highest sensitivity for size and zeta potential measurement is required.
Brookfield Engineering Laboratories has has added a fixture to its offering that tests the hardness of cosmetic pencils.
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.
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.
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.
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.
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 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.
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.
