Applied Neuroscience to Understand Cosmetic Consumers: Product Development (part III)

By measuring the non-conscious consumer response to products, concepts and before/after results, it is possible to make decisions for product development and marketing, as well as develop product claims. These possibilities are discussed in this three-part series, as are two case studies.

Applied Neuroscience to Understand Cosmetic Consumers: Definitions (part I)

By measuring the non-conscious consumer response to products, concepts and before/after results, it is possible to make decisions for product development and marketing, as well as develop product claims. These possibilities are discussed in this three-part series, as are two case studies.

Shaving And Its Effects On Percutaneous Absorption In The Skin

Shaving and its Effects on Percutaneous Absorption in the Skin*

Despite its being an area of concern for many years, the percutaneous absorption of cosmetics has not been rigorously studied. Additionally, the effects of shaving on this process are relatively unknown. An overview of recent research reveals that more research in this area is required.

Lucas Meyer Measures Consumer Response to Phospholipid Emulsifier

A study conducted by Lucas Meyer revealed that its phospholipid emulsifiers were capable of invoking positive emotion.

IFSCC 2014 Explores Social, Psychological and Sensorial Aspects of Beauty

As one might expect from an event centered around beauty and staged in Paris, the 28th Congress of the International Societies of Cosmetic Chemists (IFSCC) was nothing less than fabulous. However, the glamour and fanfare was deeply rooted in science.

Translating Sensation to (and from) Personal Care

Converging multiple sensory experiences in one personal care product can differentiate it from others on the shelf. Translating sensations to (and from) personal care will therefore be addressed by sensory expert John Hayes, PhD, at the June 22 and 23, 2015, Cosmetics & Toiletries Summit in Philadelphia.

Monell Names Margolskee Director and President

Robert Margolskee, MD, PhD, succeeds Gary Beauchamp, PhD, who is stepping down after 24 years with the organization.

Vegetable-derived, mild and sustainable skin cleansing ingredients are in demand, and this has led to the development of new detergent structures.

Testing and Developing a Sugar-derived Surfactant Blend for Delicate Skin

Vegetable-derived, mild and sustainable skin cleansing ingredients are in demand, and this has led to the development of new detergent structures. Described here is a combination of two mild surfactants that fulfils these requirements using the concept of “interrupted soap” to impart mildness. Studies to verify the functional, sensorial and mild characteristics of the new blend are detailed.

MIT Researchers Develop 'Feature Tuning' Algorithm

Researchers at MIT have developed an algorithm for the “feature tuning” of digital images, specifically faces, for improved memorability and other qualities. While the technology is implicated for effects in social media, it also suggests new considerations for digital imaging in cosmetic product development.

Columbia Researchers Uncover Touch Sensory Mechanisms

A study published in Nature highlights how a team of Columbia University Medical Center researchers have uncovered the mechanisms behind touch; i.e., how humans feel details and textures.

Measuring and Pre-selecting 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. A new method to predetermine the soft focus effects of functional filler pigments is described here.

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.

Significant Statistical Differences in Sensory Research

My dictionary has two definitions of the term significant. As others have pointed out, a research finding may be true without being important. When statisticians say a result is “highly significant,” they mean it is very probably true. Importance and meaning are determined by the consumer.

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.

Fluorescence Lscm To Assess The Penetration Of Low Molecular Protein Hydrolyzates Into Hair

Fluorescence LSCM 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.

Device for Measuring Nanoparticles and Proteins

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.

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.
