All Natural Sunscreen

14.02.2008
The exposure to ultraviolet (UV) radiation originating from sunlight can cause harmful effects on human health, such as erythema (sunburn), melanoma (skin cancer), and premature skin aging. This research provides two alternatives in producing structured lipids that has sun-screening effect and has 2 patents pending.

Project Title: Process and Production of Novel “All Natural” Sunscreen Agents

Researchers: O.M. Lai, C. Kong, C.T. Low, S.K. Lo, Rosfarizan Mohd., K. Long and Rosnah Ismail

There has been growing interest in fat and oil modification to form structured lipids, which confers desirable properties for cosmetic, nutritional and pharmaceutical purposes. Structured lipids synthesized can have sun-screening capability and also act as a solvent for dissolving fat-soluble aromatics, steroids or dyes, such as gamma oryzanol, vitamins and phospholipids in respective fields.

The exposure to ultraviolet (UV) radiation originating from sunlight can cause harmful effects on human health, such as erythema (sunburn), melanoma (skin cancer), and premature skin aging. These effects are caused by UVA (320nm to 400nm) and UVB (290nm to 320nm) radiations. Despite the availability of diverse choices of sunscreens, the search for new and improved sunscreens still continues.

This is because limitations of current products such as water solubility of sunscreen, irritation and allergic reaction caused by chemical based sunscreens and oiliness skin feel of the sunscreen itself.

This research provides two alternatives in producing structured lipids that has sun-screening effect. The first method involves the enzymatic esterification reaction between an active compound known as ethyl ferulate with an oil deodorizer distillate to produce a novel sunscreen agent. Ethyl ferulate is a scavenger and is able to neutralize any free radicals generated through long exposure to the UVA and UVB radiations.

The second method requires the production of a carrier phase in sunscreen formulation that contains high purity medium-chain triglycerides (MCT) with gamma-oryzanol as sunscreen agent. This novel method is considerably less expensive than currently known methods as it utilizes relatively inexpensive oil byproducts from the refining process of palm kernel and rice bran oil as starting materials, respectively.

The oil byproducts chosen contain both medium-chain free fatty acids and sunscreen agent. This work involves optimization of parameters for the esterification reaction, formulation of sunscreen and final evaluation of the end product to determine the stability and its effectiveness as a natural sunscreen.

This project has two Malaysian patents pending.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
