Researchers Develop Hair Counting Software

The company's software uses images captured by a small flatbed scanner pressed onto the skin.

Framework Adopted from Animal Alternative Cooperation

A framework has been adopted to increase international cooperation, collaboration and communication on alternative test methods.

The Air Up There: Skin VOCs

In 2001, Japanese researchers reported that after the age of 40, some individuals develop a malodor known as “aging odor,” attributed to the presence of unsaturated C9, 2-nonenal. George Preti, PhD, a member of Monell Chemical Senses Center and an adjunct professor of dermatology at the University of Pennsylvania School of Medicine, was interested by this report and began to conduct research of his own.

In Vitro Methods to Test Materials for Ozone Protective Capabilities

Many markers can be used to indicate epidermal stress. Therefore, it becomes clear that the skin is also a sensitive target to ozone exposure and one that could greatly benefit from cosmetic or personal care materials designed to protect against ozone.

Human Epidermal Melanocytes for Cosmetic and Dermal Studies

Lonza announces the availability of primary Clonetics Adult Normal Human Epidermal Melanocytes.

Responsilbilities in Outsourcing Clinical Testing

It remains the responsibility of the manufacturer to substantiate the safety of both ingredients and finished cosmetic products prior to their being marketed.

Sensitive Skin Syndrome: Methodological Approaches

Manufacturers of topical products perform rigorous testing to assure that their products are safe for consumers. Of particular interest is determining whether products will irritate the skin of the approximately 50% of consumers surveyed who consider themselves to have “sensitive” skin.

ACS Analyzes Microscopic Views of Hair Interaction

The ACS announced at its 236th meeting that it has carried out a microscopic analysis of hair fibers interacting with each other. The researchers find that this information will be beneficial to cosmetic chemists who formulate hair repair products.

Microscopic Scaffolding for Wound Healing, Toxicity Testing

The UK-based EPSRC announced the development of a dissolvable scaffold to grow skin tissue that could offer a new method to treat wounds, as well as possibilities for toxicity testing of cosmetics.

Measuring the Antioxidant Potential of an Acai Extract

The antioxidant potential of cosmetic materials can be evaluated by several methodologies, including a commercial kit that measures total antioxidant status, as illustrated here with a commercial extract from the fruit of the açaí, a Brazilian palm tree. Applications in antiaging products are suggested.

Ethics, Ethics Everywhere

Nowadays, however, personal care has evolved even further to encompass the root of human being-ethics and morals, where the purchase of a personal care item relates to one’s concern about the environment and animal welfare. But the involvement of ethics does not just apply to the consumers using the products; it applies to scientists conducting safety studies.

ECVAM Suggests Alternatives to FCS

The European Centre for the Validation of Alternative Methods (ECVAM) endorsed the use of non-animal serum substitutes of fetal calf serum and other animal derived supplements.
