A New Sodium Hyaluronate for Skin Moisturization and Antiaging

A new cosmetic ingredient, produced by fermentation of Bacillus subtilis as a bioidentical polymer for natural sodium hyaluronate, shows benefits for moisturizing, antiwrinkle and skin firmness in clinical tests reported here.

Quantifying Benzophenone-3 and Octyl Methoxycinnamate in Sunscreen Emulsions

The authors have validated a high performance liquid chromatographic (HPLC) method for the quantitative determination of benzophenone- 3 and octyl methoxycinnamate present in sunscreen emulsions.

Lead, Manganese and Mercury: Metals in Personal Care Products

This article is the fourth in a series reviewing the metals present in personal care products. Earlier installments appeared in January 1998, Toxic Potential from Metals Absorbed through the Skin (pages 33-42); March 1999, Metals in Personal-Care Products, (pages 47-56); and August 2000, Chromium, Cobalt, Copper and Iron: Metals in Personal-Care Products, (pages 52-65).

Whitening Complex with Waltheria indica Extract and Ferulic Acid

Waltheria indica extract, ferulic acid and certain other ingredients act synergistically in a whitening complex that inhibits tyrosinase and provides mild exfoliation.

Infant Skin Microbiology and Its Relation to Skin Health

Colonization of the skin by microorganisms is important in the overall health of an infant. This report discusses the distribution of normal microflora on healthy infant skin, and the role normal and exogenous microbes play in common skin diseases. Current and emerging treatments are discussed.

Nanotechnology and Skin Delivery: Infinitely Small or Infinite Possibilities?

Nanoparticles have been defined as single particles with a diameter less than 100 nm, which includes titanium dioxide in transparent, inorganic sun care products, and is usually extended to 200 nm to include the zinc oxide in those products. But nanoparticles are only a subset of nanomaterials, which can also include cyclodextrins and liposomes.

Patent Pick: Putting a 'Hex' on UVA and Heat

Sunscreen developers walk a fine line between protection and transparency, mainly due to the laws of physics. The inventors on this patent defy these laws with a transparent, effective and heat-releasing form of hexagonal prism-shaped ZnO particles.

Efficacy and Elegance in 21st Century Sun Care

This article discusses formulating strategies to achieve high-SPF sunscreen formulations that are cosmetically elegant and also cost-effective. By carefully choosing actives that complement one another in terms of spectral coverage, and physical and chemical properties, synergistic combinations of relatively inexpensive UV filters can be identified to deliver effective and elegant formulations.

Hypersensitive Skin: Classification and Potential Risk from Cosmetic Formulations

Considering the potential for reactions between cosmetics and hypersensitive skin, the present article will focus on this skin type; first by outlining mechanisms of type I and IV hypersensitization, then by focusing on type I immunogenic vs. non-immunogenic urticaria. Potential urticariogens in cosmetics are considered, and suggestions for future direction are given.

Lightening Skin By Inhibiting Tyrosinase and Targeting Melanosome Maturation

The complex process of skin melanogenesis renders many opportunities to identify novel means of controlling skin pigmentation. Here, novel methods of skin lightening via tyrosinase inhibition and targeting melanosome maturation are discussed.

Silicone Emulsifiers and Formulation Techniques for Stable, Aesthetic Products

Mastering formulating techniques with water-in-silicone emulsifiers can help cosmetic chemists create stable emulsions that combine distinctive aesthetics with improved performance. Here, the authors describe how altering parameters including the water to silicone/oil ratio, mixing processes, emulsifier levels, the nature of the external and internal phases, and the presence or lack of co-emulsifiers affect the characteristics of final formulations.

Multifunctionality: The Sweet (and Sour) Spot for Color Cosmetics

Multitasking beauty products are on the rise, with multifunctionality dominating many color brand strategies. The resulting growth is not without a downside.

In vitro/vivo SPF Correlation and Repeatability According to Substrate

This work evaluates the impact of three different substrates on in vitro SPF measurements, and defines experimental conditions to improve their correlation with in vivo values. Evaluations of 32 products, shown here, led the authors to conclude that molded substrates improved repeatability and correlation with in vivo SPF values.

Inhibiting Cathepsin G to Protect Against Photoaging and Infra’aging

Ultraviolet and infrared exposure are sources of premature skin aging, characterized by solar elastosis and extracellular matrix degradation. Polygonum aviculare extract is a cathepsin G inhibitor, and is shown here to oppose photoaging and infra’aging by improving skin firmness and elasticity, in turn reducing the appearance of wrinkles.

Editor's Note: A Peek into Bath and Shower Care

This month, we peek into the bath/shower scene—in a wholesome way, with a focus on issues fundamental to bath and body care. From sensory experiences, and cleansing and protecting skin, to reducing shine and acne, and more. We even spritz in a fragrance refresher.

In face powders and eye shadows, wax blends are introduced into binding systems since these cosmetics require mechanical resistance to withstand being dropped or struck.

Formulating Forum: How Waxes and Polymers Secretly Power Cosmetics

This column reviews types of waxes and polymers, their structures and functions. It also explores their properties in terms of color cosmetic product development and highlights those that are most appropriate for “green” formulas.
