Evaluating the Stability of Flavor and Fragrance Materials in Deodorant Sticks

In antiperspirants and deodorants, active ingredients or product formulations can alter the perfume oils or individual odorants in the aqueous alcoholic solutions. Thus, it is important to conduct stability tests before large-scale manufacture and distribution. In the described study, researchers evaluated the stability of various flavor and fragrance materials in deodorant sticks containing active ingredients.

Future of Green and Niche Markets Explored at MWSCC Technical Symposium

Over 110 attendees flocked to the Belvedere Events & Banquets in Elk Grove Village, Ill., USA, to attend the Midwest chapter of the Society of Cosmetic Chemist's (MWSCC) Fall Technical Symposium on Oct. 10, 2013.

Non-Invasive Measurement of Epidermal Proteins for Psoriasis and Skin Care*

Abnormal epidermal turnover in psoriatic skin impairs its barrier function and tissue repair capabilities. Therefore, studies of hyperkeratinization and hyperproliferation have been conducted to better understand the disease. Here, the administration of heavy water and a tape-stripping method are used to measure skin protein turnover in psoriatic skin and surrounding tissues. Results demonstrate benefits over other proliferation measurements.

The Dr. May brand B3 Acne Solution won the C&T Allē Award for Most Significant Skin and Body Care Formula in the mass category. This sponsored video explains how it aligns with future acne care; along with a new idea in anti-aging. Watch now.

Developing Sunscreens for the Preventive Treatment of Photodamage and Premature Aging

This article reviews the mechanisms of ultraviolet radiation insult to skin and explains the formulation of sunscreens to protect against this damage. Further, since the efficacy of combinations of UV filters will vary with formulation base, the formula vehicle and form are discussed, as well as an overview given of typical sunscreen efficacy tests performed prior to production.

Structured Surfactant Systems for Deposition of Perfume on Skin and Hair

To maximize perfume delivery from structured cleansing formulations, the fragrance must be introduced before structuring the formulation into multilamellar vesicles. Structured formulations fragranced in such a way are shown here to improve perfume deposition and duration versus micellar systems, with no negative impact on perfume burst during use.

Performance and Sensorial Benefits of Cationic Guar in Hair Care Applications

Cationic guars have demonstrated ability to manage the surface of the hair. This article discusses their physico-chemical properties, their hair conditioning and repairing properties, and their impact on foam sensorial aspects.

New Liposome Gels by Self Organization of Vesicles and Intelligent Polymers

A new technique for forming liposome of lamellar gels calls for the build up of a nanoarchitecture of lipsomes (lamellar phases) crosslinked with hydrophobically modified water-soluble polymers (self assembly of vesicles and polymers).

Bench & Beyond: Pigment Ideas from the Kingdoms of Animals and Microorganisms

Butterflies, bacteria, yeast and fungi are providing new ways to color cosmetics, thanks to recent developments in microscopy, microbiology, nanotechnology and biotechnology. Although cosmetic colorants are highly regulated, certain colorants from plants and minerals do not require certification and have long histories of use in cosmetics.

Dermal Tolerance, Safety and Efficacy of Insect Repellents in Personal Care

This article discusses the main commercial insect repellent active chemicals and their efficacies in light of their tolerance by the human skin and body. Implications for finished product formulation are also discussed.

Results indicated that sago starch could potentially be used as the main component in body powders.

Feasibility Study of Sago Starch for Perfumed and Cooling Body Powders

In the present article, sago starch-containing perfumed and cooling body powders are formulated and their physicochemical properties for potential skin irritation are examined. The results indicate that sago starch could potentially be used as the main component in body powders.

Enhancing the Stability of Natural Oils and Butters with Rosemary Extracts

Use of rosemary extracts to provide oxidative stability to various natural oils and exotic butters offers a way for formulators to reduce the use of synthetics and chemicals in skin care products.

Preservative Efficacy Testing of Aqueous Cosmetics and Drugs without Counting Colonies

A miniaturized system using broth enrichment followed by either streaking on agar or fluorescence treatments can eliminate colony counting in the linear regression method of preservative efficacy testing.
