Soaking up the Self-Tan: The Pros and Cons of DHA and Self-tanners

Many people utilize non-UV tanning methods to meet fashion demands without exposing themselves to UV radiation. This article reviews the health benefits and possible drawbacks of dihydroxyacetone, the main active ingredient in self-tanning products.

Nanoencapsulation for Extraction and Release of Fragrance

This article discusses the synthesis of nanoparticles by inverse microemulsion polymerization and evaluates its potential to extract and release the fragrance linalyl acetate. The ability of the liposomes made from phosphatidyl choline and phosphatidic acid to extract organic molecules also was explored.

Safety and Efficacy of Microfine Titanium Dioxide

Modern microfine TiO2 products attenuate both UVA and UVB. The ingredient is practically chemically inert and “non-penetrating” and can be regarded a safe cosmetic raw material.

Mechanisms of Tape Stripping and Protein Quantification

In this article, several methods to quantify the protein collected by tape stripping are described, including traditional gravimetric methods as well as novel colorimetric and visible spectroscopic techniques. Further, one colorimetric method is described to effectively determine the keratolytic efficacy of various materials in vivo, suggesting additional roles for this method.

The Long and Short of Hair Care

In personal care, the hair care market holds an impressive second only to the booming skin care segment.

The Photostability and Photostabilization of trans-Resveratrol

In this study, the effects of ultraviolet radiation (UVR) on trans-resveratrol were documented, finding that UV radiation causes it to undergo rapid and extensive photoisomerization and some photodecomposition. The antioxidant activity of trans-resveratrol is correspondingly reduced. However, in the presence of ethylhexyl methoxycrylene, a photostabilizer used in sunscreens, the effects of UV exposure on trans-resveratrol are minimized, thereby preserving its antioxidant activity and, presumably, its bioavailability.

Approaches to and Characterization of Hair Growth

There is still more to learn about hair growth control and what influences the follicle. The translation of what is learned into effective treatments is not keeping pace. This review offers some biology of the hair cycle and comments on differences between kinds of hair and hair treatments.

Efficacy of Self-Tanners and Other Topics

Giacomoni reviews skin protection by the use of sunscreens, suntan, and antisun burn preparations. Until recently, the only strategy affording the protection of the skin against the harmful effects of solar radiation was to reduce the number of impinging photons with fabrics, umbrellas, hats, sunglasses or sunscreens.

Computerized Measurement and Correction of Color Cosmetics

With a spectrophotometer and computerized color measurement software, the cosmetic chemist can do both basic color quality control and color formulation and correction easily in the lab.

Each chapter delivers a critical evaluation of a delivery technology open to the cosmetic formulator.

Science and Applications of Skin Delivery Systems

Written by experts in their specific delivery subject who are passionate about their subject, this book is a special delivery system of its own! Each chapter delivers a critical evaluation of a delivery technology open to the cosmetic formulator. This allows the reader to decide what delivery system or delivery technique is most appropriate for his or her application based on scientific evidence.

Use and Labeling of Nanomaterials in the EU

Although originally presented as a consolidation and simplification of the Cosmetics Directive and its complex amendments, the recasting of the directive into a regulation for cosmetic products was used as an opportunity to extend the scope in several areas. One of these concerned the use of nanomaterial in cosmetic products, now defined in Article 2(k) of the regulation. It states, “‘Nanomaterial’ means an insoluble or biopersistent and intentionally manufactured material with one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm.”

Emerging Technologies and the Future of Cosmetic Science

In this article, the authors look forward to what cosmetic science might be like in the future with what emerging technologies, radio frequency identification (RFID) tags and nanotechnology, may offer to the cosmetics industry.

The Blossoming of Naturals--Part II: Marketing and Statistics on the Impact of Wellness/Naturals Globally

How many of you regularly exercise—yoga included? How many of you consider yourself a tree hugger? You don’t have to be a tree hugger to embrace the natural and wellness trend.

Fragrance and Raw Materials: Birds of a Feather

There is more to fragrance formulation than meets the eye—or nose that is. Both raw material and fragrance formulators spend significant time in the lab testing different materials to determine which ingredients, oils, extracts, etc. best meet their formulation and consumer’s needs. And although fragrance and personal care are two different industries, the discovery processes prove similar.
