Hidden Hair Damage and the Importance of Multiple Tests

It is of paramount importance for hair researchers to know the history of hair at the time of applying a treatment. The lack of such knowledge can create misleading results. Thus, a stress-strain test in both dry and wet states can provide a rapid means to check the reliability of the information collected, as is shown here.

EC, EFSA to Examine Endocrine Disruptors

The European Commission Directorate General for Health and Food Safety will hold a one-day conference in Brussels on June 1, 2015, to determine the criteria to identify endocrine disruptors and the European Food Safety Authority will participate.

Analytical Techniques for Hyaluronic Acid Formulation

This article reviews the characteristics and structure of hyaluronic acid (HA), then explores how multi-detector gel permeation/size exclusion chromatography (GPC/SEC) and microrheology techniques can be jointly applied to determine the structure-function relationships that support the successful inclusion of HA in cosmetic formulations. Experimental studies are provided to highlight the value of these techniques.

3D Printed Skin Animal Test Alternative

San Diego-based Organovo announced a partnership with cosmetics giant L'Oréal to develop 3D bioprinted skin tissue for the beauty product testing.

Taiwan Proposes Animal Testing Ban for Cosmetics

Legislator Wang Yu-min and the Taiwan Society for the Prevention of Cruelty to Animals (SPCA) proposed a bill advocating the #BeCrueltyFree Taiwan campaign, which would ban the animal testing of cosmetics in Taiwan.

Defining and Controlling Frizz

There is likely a variety of causes and contributors to the nebulous consumer term “frizz.” This article attempts to craft a universal definition and then progresses to further examine impacting factors. These discussions focus on methods for quantifying hair properties and assessing the positive impact of commercial hair care products.

Sea Anemone Delivery of Collagen and γ-PGA for Anti-aging Benefits

The effective delivery of youth-preserving collagen and moisture remains a cosmetic Holy Grail. In response, this study describes a natural microinjection system based on the stinging cells of the Cnidaria sea anemone to effectively puncture the stratum corneum layer and deliver its content—both marine collagen and γ-PGA—into skin, offering a promising new class of solutions to age-old challenges.

Smart Lipid-carotene System for Targeted Free Radical-Scavenging

In this study, the authors evaluated the effectiveness of a new smart lipid system in stabilizing and delivering carotenes into the epidermis. The system is shown effective in providing free-radical (FR) scavenging at different stages of skin exposure: immediately neutralizing FR present in the skin, blocking FR formation during UV exposure, and accelerating skin recovery after UV exposure.

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.

A Novel Explant Model for Skin Delivery Assessment

Mechanisms implied in the skin absorption process and the role of cutaneous metabolism are of increasing interest to cosmetics research. In the present paper, the authors demonstrate how an experimental human skin explant model exhibiting great barrier function and metabolic activities can provide an understanding of what happens to cosmetic actives when they are topically applied.

Quantifying Hair Color Fading

Around 10-12 years ago, shampoos and conditioners began appearing on the market claiming to be “color safe.” This strongly resonated with consumers. The present article discusses various contributors to the color fade process with a specific emphasis on measurements to quantify and understand color fade.

South Korea May Be Ending Animal Testing for Cosmetics
