Ferulic Soy Glycerides for Personal Care Products

iSoy Technologies has created ferulic soy glycerides (FSG), an active ingredient derived from soy oil and ferulic acid.

Enzymatic Synthesis of Isoamyl p-Methoxycinnamate from the Natural Ethyl Ester

The naturally occurring ethyl ester of p-methoxycinnamic acid can undergo efficient enzymatic conversion into the corresponding isoamyl ester via lipase catalysis using natural isoamyl alcohol as reactant. This transesterification provides a natural route to a popular sunscreen filter.

UVA Skin Protection: Issues and New Developments

Photoinduced degradation and activity in chemical and mineral UV-absorbing actives results in a decrease in UVA protection during topical use, with a corresponding risk of skin pathologies in the user. New developments in UV absorbers are shown to maintain a stable, high level of UVA protection during use.

Protecting Skin from UV Oxidative Stress with a New (Cys-Gly)2 Dimer Peptide

In the presented studies, researchers investigated the effect of the (Cys-Gly)2 dimer peptide against UV-induced oxidative stress on cultured human fibroblasts. The dimer peptide was found to act on a range of mechanisms involved in cell defense against such stress.

Derm View: Chemoprevention of Skin Cancer: Role of Antioxidants

Skin cancer is diagnosed in more than 1.5 million people yearly and more than 90% of the cases are believed to be related to sun exposure. This article discusses current knowledge on the biological process of UV-induced skin damage. Of particular interest is the role of antioxidants in the prevention of carcinogenesis.

Photostability: The Back Story of UV Filters

Here’s the story of organic UV filters. They absorb a packet of energy called a photon from incoming UV radiation and hold it briefly in an excited state before releasing it as heat or a lower-energy photon or both, and returning to the unexcited or ground state.

Global Developments in Sun Care Ingredients

Despite regulation limitations, more and more new ingredients, products and techniques for the sun care industry have been introduced. The regulatory status of currently approved UV filters and the introduction of new and improved UV filters will be reviewed.

Multifunctional Ingredients: The Novel Face Of Natural

A natural extract that affords comprehensive “bioprotection” is derived from turmeric root and offers versatile applications in personal care formulations. Its salient feature is multifunctionality in anti-aging compositions.

Frequency of Use of Organic UV Filters as Reported to the FDA

The author reports on frequency of use of 17 organic UV filters in nearly 18,000 formulations voluntarily reported to the United States government as of May 2003.

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.

Chinese Medicinal Plants Up-Regulate Melanin Biosynthesis In Vitro

Experiments based on UV absorption measurements show that water extracts of several Chinese medicinal plant materials are able to up-regulate the biosynthesis of melanin in vitro.

BEMT: An Efficient Broad-Spectrum UV Filter

Efficient broadspectrum UV protection is provided by bisethylhexyloxyphenol methoxyphenyl triazine (BEMT), an oil-soluble, photostable UV absorber that offers improved UVA protection and synergy with UVB filters.
