Changes in temperature, humidity and how you spend your days will all contribute to a change in how your skin acts. Each individual's skin will need different products at different times of the year (or the week for that matter!
This week I attended what was, I think it is fair to say, the oddest conference I have been to yet. It was the first world congress of the Digital Olfaction Society (tagline: “The Smell of Digital”), the stated goal of which is to “digitize, transmit, reproduce and recapture smells, flavors and fragrances.” You know that perennial April Fool’s joke about sending odors through the internet, most recently spun up by Google?
The thing is, as my colleague Barb Darrow pointed out in the wake of Google’s gag this year, there really are serious efforts underway to make the digital capture and production of aromas a reality. The conference was small, but the participants spanned the disciplines of computer science, biochemistry, engineering, smart clothing design and perfume retail.
The society is the brainchild of Dr. Marvin Edeas, who is also the president and founder of International Society of Antioxidants in Nutrition and Health, and Professor Takamichi Nakamoto of the Tokyo Institute of Technology’s engineering school, whose team is gradually refining its smell detection and generation systems.
Edeas’s specialty is the fight against aging and obesity, and he is intrigued by the recent discovery that aroma can activate intestinal receptors, making people feel more full than they are. Pointing out that experiments have also shown dogs can smell cancer and diabetes, he foresees the development of a “digiscented world” where smells are deployed and captured for medical, gaming, security and justice purposes, and where cinemas use a version of Smell-O-Vision that actually works.
The citrus flavor and aroma of grapefruit — already used in fruit juices, citrus-flavored beverages, and prestige perfumes and colognes — may be heading for a new use in battling mosquitoes, ticks, head lice and bedbugs thanks to a less expensive way of making large amounts of the once rare and pricey ingredient...
A report on the new technology for making the ingredient, nootkatone, which previously had to be harvested from tons of grapefruit, was part of the 246th National Meeting & Exposition of the American Chemical Society (ACS), the world’s largest scientific society...
“A new product based on nootkatone would have multiple advantages over existing mosquito repellants based on DEET,” said Richard Burlingame, Ph.D., who presented the report. “Nootkatone is a broad-spectrum ingredient that has been shown to be effective as a control agent for mosquitoes, ticks and bedbugs. Nootkatone has been used for years to give beverages a grapefruit flavor. It is safe to eat, has a pleasant citrus flavor, is not greasy, both repels and kills insects, and should not have the toxicity concerns that exist for DEET.”
Burlingame, who is with Allylix, Inc., a renewable-chemical firm... cited nootkatone as an excellent example of the potential for developing new pesticides based on natural sources. Nootkatone is a component of the oil in grapefruit, and has been on the U.S. Food and Drug Administration’s list of substances generally recognized as safe for use in food. It has been in commercial use for years as a flavoring for foods and beverages and as a fragrance ingredient in perfumes. Those applications require only tiny amounts of nootkatone, and price — $25 per ounce when extracted from grapefruit — was not a major concern. It was slightly less expensive when produced from a substance called valencene, extracted from oranges.
The need for a more economical source of nootkatone intensified after scientists at the U.S. Centers for Disease Control and Prevention (CDC) discovered nootkatone’s effectiveness in controlling ticks, mosquitoes and other insects. Nootkatone extracted from grapefruit, however, would be too expensive for development of a consumer product... Allylix used proprietary technology to develop a way of producing valencene from yeast growing in industrial fermentation vats. Technicians harvest the valencene and use a chemical process to convert it into nootkatone. Allylix said the process made it possible to market nootkatone at a competitive price.
“The effects of nootkatone last much longer than those of repellents currently on the market... And nootkatone shows promise for being the most effective agent for the ticks that cause Lyme disease.” Nookatone also works in a new way, so it can be used against insects that develop resistance and shrug off conventional pesticides, and yet would be very unlikely to harm people or pets.
Allylix currently sells nootkatone only for use in flavor and fragrance applications. The next step involves getting approval from the U.S. Environmental Protection Agency to sell nootkatone for insect control. “They haven’t approved it yet, so no products currently on the market in the U.S. include nootkatone as an active ingredient to control pests... But in the future, it could be a key ingredient in repellents for use on clothing or on skin as a spray, or even as a soap or shampoo.”
Loriblu fragrance for woman is a very glamour and feminine perfume, characterized by fresh bloomy scents with a powdery and citrus heart, accompanied by natural notes of musk. Loriblu fragrance is contained in a chic bottle, tied by a black ribbon with the classic Loriblu "L" studded with Swarovski crystals. Packaging is also very linear and elegant: a shining gold colour for the sophisticated and refined Loriblu's woman.
Fragrant flowers lure us into the garden, and keep us there. The spicy scent of lily-of-the-valley may remind us of a favorite neighbor, while a whiff of honeysuckle transports us back to childhood summers in the country. We accept the beautiful aromas of the garden as gifts meant for us personally, even though they are intended strictly for the birds and the bees. Nearsighted pollinators rely on fragrance to guide them to nectar-filled blossoms; like us, they may become intoxicated and find themselves unable to leave a favorite flower. Just as some insects are attracted to specific plants, we humans have our individual preferences. What are yours?

Those pesky mosquitoes snacking on your arms and legs aren’t only out for blood. Like most other creatures, they have a favorite food. In their case, it’s sweet, succulent flower nectar. Mosquitoes don’t pollinate flowers as other insects do. After sniffing out a floral fragrance, they track down the plant and steal its nectar for energy. That weakness for nectar, however, could be their kryptonite. Using flower scents created in a lab, a team of researchers at Ohio State University plans to lure mosquitoes into traps. The objective: Kill the pests that carry life-threatening diseases, including West Nile Virus and malaria.
The first step was building a machine, called an olfactometer, to detect and measure odor. That started in 2006. The team began analyzing plant chemicals in 2008 and got to the tests two years later. The experiment was simple: Give a mosquito two options and see which one it chooses. The research team plans to take its study into the field soon, but the venture won’t be without its challenges. For example, synthetic scents might not be as effective as the real thing outside the lab. They hope someday to expand the study and identify scents that would attract a host of mosquitoes around the world, particularly those that transmit malaria in African countries, where a child dies every minute from the disease, according to the World Health Organization.
