UV Transmission Assessment: Influence of Temperature on Substrate Surface

This work evaluates the impact of temperature on test substrate surfaces during the application, spreading and drying steps of the in vitro method to measure ultraviolet (UV) transmission. The authors work in a range between 20°C and 35°C, and demonstrate that controlling temperature is a key test parameter that should be strictly controlled to ensure reliability.

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.

Brookfeld Designs Fixture to Test Cosmetic Pencil Hardness

Brookfield Engineering Laboratories has has added a fixture to its offering that tests the hardness of cosmetic pencils.

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.
