‘How Did THAT Get in There?’ Identifying Particulate Contamination in Products and Packaging

Particulate contamination and discoloration may occur in products due to foreign materials introduced via raw materials or during the manufacturing process. Agglomeration or reactions between ingredients and packaging components also are possible sources. The identification of contaminants and their origin, described here, is therefore critical so that future incidents can be prevented and safety or regulatory concerns can be addressed.

Determining Korean Consumers’ Degree of Exposure to Lipstick and Face Creams

This study describes methods used in a Korean study to calculate consumer exposure to lipstick and face creams. The average amount applied daily was estimated and compared with data collected by weighing containers before and after use. The data collected was 1.8 to 1.6 times greater than the estimate, so although the survey represented real use patterns, the actual data was more accurate.

Using In vivo and In vitro Testing for Evidence-based Development of Anti-aging Ingredients

The need for a conceptual approach to skin aging, the need to combine in vitro and in vivo findings and the new direction for cosmetic ingredient manufacturers are discussed here.

Inducing Hormesis for a Lipofilling-like Action

The present article discusses a new approach to mimic lipofilling—the activation of hormesis, which is accomplished by the described encapsulated active designed to induce a transitory stress and initiate an overcompensation to reestablish homeostasis. This leads to the compensation of age-induced lipoatrophy and correction of wrinkles and folds, for a younger-looking appearance.

Clinical Evaluation of a Zinc- and Copper-based Eye Area Anti-aging Complex

A zinc and copper complex generating biomimetic electricity on a physiological level is shown here to improve the signs of photoaging in preclinical and clinical studies. This complex was applied to the eye area to confirm its efficacy as an anti-aging treatment option with good skin tolerance.

Designing Mild Personal Care Products: A Case Study

This article reviews the mechanisms underlying skin irritation and sensitization, and methods used in a case study to test cosmetic products for their potential to cause irritation. It also covers the main skin conditions that can influence susceptibility to irritation, as well as ingredients affecting the mildness of cosmetic products.

Improved UV Testing to Prevent Product Degradation

Atlas Material Testing Technology has launched the fourth generation of its SUNTEST CPS+ with improved features such as improved quality of light, an easier viewed larger display panel, eight user languages and two pre-programmed test methods.

Non-animal Transdermal Diffusion Model Testing for Cosmetic Actives and Formulations

Experience the unmatched predictability of Strat-M membrane—a synthetic, non-animal based model* for transdermal diffusion testing that is predictive of diffusion in human skin without lot-to-lot variability, safety and storage limitations.

Detecting Estrogenic Endocrine Disruptors in Personal Care Products and Supplements

Endocrine disruptor chemicals (EDCs) are a class of chemicals that has raised alarm for being linked to a wide variety of detrimental effects on human and wildlife populations, e.g., cancers, precocious puberty and obesity. Thus, there is a need to test personal care products and supplements for EDCs, which can be accomplished using the validated bioassay described here.

Stability Testing

Cosmetic companies support and conduct stability study programs because it is good business. Any improvement in stablity of a product is important for product performance, consumer satisfaction and economics.

Permeation Method Developed As Alternative to Franz Cell

Pion Inc. has introduced a test method that predicts the permeability of drugs and dermal formulations through the human skin without the cost and low throughput restrictions of the Franz cell chamber.

NICEATM Calls for Scientific Experts and Data on Eye Testing

The National Toxicology Program Interagency Center for the Evaluation of Alternative Toxicological Methods (NICEATM) is looking for scientific experts and data for a scientific review panel.
