Characterizing and Evaluating the Effectiveness of Volcanic Pumice Exfoliants

Pumice has a recognized application as an abrasive agent to promote exfoliation of the skin. In this study, different particle size fractions of pumice sampled from several geologic occurrences in São Miguel’s island, the Azores archipelago, were used in the preparation of exfoliation formulations. Gels and soap were prepared and characterized, and their efficacy evaluated.

Wild Plum, Nano Self-assembly Delivery, Rice Leaf Self-cleansing and More

Following is a sampling of recent scientific literature as assembled by Rachel Grabenhofer, editor of Cosmetics & Toiletries, which was found to have potential impact on personal care.

Chinese Licorice Extract for Anti-aging, Antibacterial and Breath-freshening Effects

This article reviews in vitro studies that have found Chinese licorice extract to impart potent antibacterial and soothing properties, which make it an interesting candidate for applications in oral and personal care. Further, a clinical study is described in brief, assessing the ability of a supercritical CO2 extract from Chinese licorice to impart breath-freshening properties.

Caprylyl Glycol/Phenethyl Alcohol Blend for Alternative Preservation of Cosmetics

In recent years, the safety of traditional preservatives has been called into question. Therefore, there is a need for alternatives that are effective, safe and sustainable—and that are non-controversial. In response, the present work investigates a mixture of caprylyl glycol and phenethyl alcohol, which is shown to provide antimicrobial activity in various skin and hair care formulations.

Stimulating Sirtuins' Antiaging Appeal

Nicotinamide, the amide of niacin or vitamin B3, is used to treat arthritis. It also has demonstrated anti-inflammatory actions that may be of benefit in patients with inflammatory acne vulgaris. Nicotinamide, therefore, would appear to play a positive role in inhibiting inflammation but a negative role in aging. Are there other ways to stimulate sirtuins?

Formulating Focus: The Influence of Emollients on Skin Penetration

This column will discuss ways in which ingredients can positively affect the partition coefficient of the active between the formula and the skin. By carefully selecting the emollients used in a formulation, formulators can increase the delivery and clinical efficacy of a formulation without increasing the level of the active ingredient.

Technically Speaking: From Enzymes to Fragrance Ingredient Testing: A Literature Overview

Sirtuins: A Breakthrough in Antiaging Research

This article reviews the first scientific evidence confirming the presence of sirtuins in the skin, as well as their role in cell survival, senescence and longevity. This vital discovery could lead the way to new and innovative types of antiaging cosmetic ingredients that activate sirtuins.

Patent Picks—Melanin Stimulator, Broad-spectrum Antioxidant, AHA Boost to BHA Solubility and More

Patent Picks are taken from publicly available sources, and cover recent patents issued or patent applications in cosmetics, personal care and peripheral markets. This edition features technologies related to skin care actives.

Treating Spider Veins

Spider veins are popping up, literally, all over the world. This article attempts to establish possible causes for spider veins in addition to exploring their current and future treatment.

Heralding the Future, Appreciating the Past

In this month’s issue, we honor Maison “Ed” G. deNavarre. Not only did this legend inspire the creation of the IFSCC and pull together an encyclopedia of knowledge that still resonates, he drove emulsion technology to new heights.

The arNOX Enzyme: Implications for Intrinsic Aging

This article describes a membrane-bound enzyme found in skin whose activity increases as biological age increases. The enzyme, located on the external surface of fibroblasts and keratinocytes, generates free radicals. The present work identifies the biological mechanism of the enzyme and its relationship to the appearance of aging in skin.

In Sight: Stimulating Stem Cells for Younger Skin

Stem cell research is a hot topic that cannot be ignored in today’s scientific realm. Its research may lead to the reversal of Parkinson’s and diabetes, to the growth of new organs, to strengthening bones and to healing damaged skin. The research of stem cells in conjunction with burn victims has led to innovation in another field—skin care.

A Green, Solvent-free Biocatalytic Method to Produce Cosmetic Esters

Cosmetic esters can be produced effectively via a solvent-free, biocatalytic method. This green process, described by the authors, involves combining two reactants and an enzyme, and is driven to high conversion by the removal of by-products through a nitrogen purge—in turn producing high purity materials directly from the reactor.

Benzoyl Peroxide A Review

Improving the Solubility of Benzoyl Peroxide: A Review

In this review, the authors examine studies relating to the solubility of BPO. The clinical trials discussed show that compared with suspended BPO, BPO solubilized by dimethyl isosorbide reduced P. acnes and decreased both inflammatory lesions/irritation and the emergence of antibiotic-resistant P. acnes strains. This reveals the importance of solubilizing BPO for improved efficacy and safety.

Mitochondrial Nourishment and Protection for Antiaging Effects

Multiple factors affect the integrity of cell mitochondria, leading to loss of cell function, aging and apoptosis. In skin, this is expressed in the form of wrinkles, loss of tone, etc. To combat these effects, the author describes a technology that contains mitochondria-nourishing compounds to deliver antiaging benefits.

Cell Signaling in Psoriasis for Ingredient Evaluation and Product Design

In this paper, the authors focus on the dialogue between skin epithelial cells and immune cells in the context of an inflammatory situation, i.e., psoriasis. The aim is to design in vitro models relevant to in vivo skin inflammation that can then be used to screen and evaluate potential cosmetic products.
