Our work is multi-dimensional and complex; a meeting of science and art, creativity and data. Here you will find frequently asked questions to help you understand our world of fragrance. From technical terms to why we like what we like, the olfcative memory to practical tips on storing and wearing fragrance contact us if you have any lingering unanswered questions. You may feel that there can be no logic in your choice of perfumes because your sense of smell is so emotional, but the fragrances you most enjoy will probably belong to just one or two of the fourteen different fragrance families.
Like most good things, it takes a little effort to find a new perfume that is just right. I recommend starting by understanding the difference between the fragrance families. You can do this by exploring my Fragrance Wheel. To see other fragrances in the same family, try my one of my fragrance matching products.
No more than three. Although you will find your sense of smell tires more quickly from similar fragrances than fragrances of very different character, you risk confusing your sense of smell if you test more than three different scents at one time.
You may assume that fragrances are confusing, a jumble of different perfumes with no rhyme or reason. If I classify the fragrances you have worn, I will probably find that they fall mostly into just two or three families.
Once you know the families you especially like, my Fragrance Reference Guide will show you which other fragrances belong to the same family. Apply a few drops or the lightest spray to your wrist or the back of your hand.
Wait a few moments. When you sniff an open bottle, your nose inhales the sharp bite of alcohol and the volatile top notes. A fragrance needs your skin to come alive. It blooms as it reacts with the warmth of your body to create a fragrance that is unique to you. Test on blotting paper or a tissue. Odour molecules pass through your nasal passages to two tiny patches located behind the bridge of the nose. These patches are made up of millions of special olfactory or smelling sensors.
The odour molecules dissolve in moisture and bind to tiny nerve hairs on the cells. Recent research has found that every cell is equipped with as many as a thousand different receptors, each designed to respond to a small group of different odours. These send messages about the odour to the limbic system, the part of the brain that governs moods and certain emotional responses.
While the limbic system is largely devoted to smell, it also influences our hormonal, metabolic and stress responses and is the emotional centre for sexual desire, rage, fear and joy. Depending on your individual sense of smell, between 5, and 10, Because it helps us feel good about ourselves and others. Recent psychological tests show that people who use fragrance regularly have a more positive attitude towards socialising and may be more socially skilled than those who seldom or never wear it.
It was generally found that people who believe that others think they smell good have more confidence. More fun, too? Because we all are programmed to like certain smells and dislike others. Our response to odour and fragrance, say scientists, is partly learned and partly genetic. We are born with definite likes and dislikes, as well as sensitivity to certain smells. All this stored information determines whether or not we like a fragrance.
Because smell triggers the associative memory of clusters of events and feelings. Build up layers of scent on the skin by using different forms of the same fragrance - perfumed soap, bath oil or gel, body lotion or cream, dusting powder and eau de toilette. Each reinforces the impact of the other to quadruple the life of your favourite scent. Keep your fragrances in a cool, dry place away from direct sunlight and heat sources such as radiators. Extreme heat or cold will upset the delicate balance of the oils and change their scent.
Once a bottle of perfume is opened, use it. A spray lets in less air and evaporates slower than a bottle with a cap but even the finest essence fades with time. The best place for opened fragrance is in a closed drawer or wardrobe. Where the skin is especially warm and where there is good blood circulation. This is because heat helps diffuse and magnify the aroma of fragrance. Because fragrance rises, it should be applied to several pulse points - not just, for instance, at the base of your throat.
Consider the small of your back and your navel. If you prefer to have your fragrance trail you, apply it at the nape of your neck — just on the hairline — the heat and movement will diffuse your fragrance. Inside your wrists. Inside your elbows. At the temple. Below your ear lobes, not behind. At the base of your throat. Behind your knees. And anywhere else you feel a heartbeat. Spray about 20cm away from your skin. An even spray over a wider area will help your fragrance last longer than a generous amount in a small area.
Should you rub one wrist against the other to dry the fragrance? Try the lightest spray through damp hair before you blow dry, or mist your hairbrush and comb with fragrance before use. Add a few drops of perfume to the water in a steam iron to lace clothes with fragrance, or rinse lingerie in scented water. If fragrance can make you feel so good, why not use its power? Preferably not because each perfume is a balanced, complete creation. That said, there are some fragrance houses that specifically design their fragrances to be layered with eachother.
Diffusion is the ability of a scent to reach out from your skin and surround you and others with its aura. The ability of a scent to travel through the air - its effusiveness - is the test of a great perfume. Depending on the fragrance, from months, if stored correctly.
Once a bottle of fragrance has been opened it should be used because all fragrance deteriorates with time: light, citrus-based perfumes in as little as six months; floral scents in about a year and a half. To most people, the words essentially mean the same, and you can safely use one or the other. You will find that usage varies from country to country: in the United States, fragrance is the more common description; in England, scent or fragrance.
In France? The fragrance industry tends to refer to the most concentrated form of a scent as perfume or parfum in contrast, say, to the less concentrated eau de toilette or cologne. Perfumers, on the other hand, use the word specifically to describe their fragrant creations, their perfumes.
Perfume, parfum or extrait is the most concentrated, longest-lasting fragrance form with 12 to 30 per cent perfume oils. The newer Eau de Parfum or Esprit de Parfum interpretations are almost as concentrated as the traditional extraits, but the Parfum de Toilette or Eau de Toilette a Cologne, in the United States is a lighter strength, with a level of fragrance anywhere from 4 to 18 per cent.
In Europe, the word Eau de Cologne describes a very light level of fragrance, only 1 to 3 per cent oil. Colognes or eaux de toilette are meant for your body, aftershaves for your face.
Eaux de toilette or Colognes are blended with more fragrance - anywhere from 5 to 15 per cent essential oils - while aftershaves have a lighter scent, usually around 2 to 4 per cent, less alcohol 30 to 65 per cent and incorporate soothing emollients and calming antiseptics.
How is a painting painted, a symphony composed? What is certain is that perfumers use their materials in much the same way as painters use their colours, musicians their notes. You have an inspiration for a mixture of those three or four bodies, not more. After that, you have to enhance her, make her more beautiful, do her hair, select her dress, her lipstick, her eye liner, her hat, her wrap - and that is a perfume.
Dutton, I could never find a scent that would be right on the tennis court, so I had to invent it. A perfumer is rarely a soloist.
The conductor of the orchestra, the head of a perfume house, plays a critical role. Like a great symphony, a truly great perfume evolves with a sensory message so emotional, it moves the hearts of women and stirs the senses of men. It varies. They are the different phases through which a fragrance develops when you spray it on your skin.
The head or top notes are the first impression of a fragrance. These are the light volatile notes that burst on your skin as you first spray, the fragrance you experience as you open a bottle. The head notes are so volatile that they usually wear away within 10 to 15 minutes. As they fade, the heart or middle notes bloom on your skin. These form the core of the composition, and are the dominant theme of the fragrance. This theme is accentuated and fixed by the base or soul notes.
These are the foundation of the fragrance, the notes that bind the other ingredients together. They create the memory that makes the theme linger in your mind, and make the fragrance last for some four to five hours on your skin.
It varies from person to person. Usually, a perfume or extrait, the most concentrated form, should last for six to eight hours; an eau de toilette or American cologne, for three or four hours, sometimes longer if it is more concentrated. Summer heat increases the impact of odour.
The answer: a lighter fragrance re-applied more frequently.
Where you keep your scents is very important, as heat and natural light can oxidize the liquid and change its composition. It helps keep the perfume as true to its intended smell as possible. The easiest way? Store them in their original boxes. Not only is the packaging beautiful, but also protect your precious perfume from direct sunlight. If you have dry skin, your fragrance will never be able to last as long as you want it to.
Fragrance Q&A with Michael Edwards
The present invention relates to ethanol-free perfumed compositions suitable for leave-on cosmetics, said compositions being clear, transparent and stable during storage. The invention is also directed to ethanol-free perfumed products obtainable by dilution in water of ethanol-free perfume preparations. Historically, perfumes have been prepared by dissolving fragrance oils in volatile alcohols, primarily ethanol, or in a mixture of ethanol and water. The industrialization of surfactants and the advances in colloid science have made possible the solubilization of fragrances in water by means of emulsification with surfactants. When an emulsion has a particle size of about nm or less it is referred to as a microemulsion.

The particles protect the perfume from oxidation by the bleach during storage and use of the composition. The invention thereby provides improved product odor, odor during the laundry process, and delivery of perfume to fabrics. The perfume particles are preferably admixed with detergent or bleach granules to provide finished granular detergent or bleach compositions containing peroxyacid bleaches. Perfumes are a desirable part of the laundry process. They are used to cover up the chemical odors of the cleaning ingredients and provide an aesthetic benefit to the wash process and, preferably, the cleaned fabrics. Perfumes are often added directly to laundry compositions, such as by spraying the perfume onto finished compositions. However, perfumes are, in general, volatile and many perfume ingredients can be destroyed or damaged by contact with cleaning ingredients, especially alkali and bleaches. To minimize direct contact between perfume and bleach components in laundry compositions, bleaches are sometimes admixed after perfume spray-on. Even this does not avoid oxidation of perfumes by bleaches, particularly when reactive bleaches such as peroxyacids are present. One solution to this incompatibility problem is encapsulation of the perfume.
This application claims priority from European Patent Application No. This invention relates to perfumed, aqueous microemulsion compositions which are low in volatile compounds. These compositions can be used e. The need to have cosmetically acceptable, low or zero ethanolic fragrance formulations is due to concerns about volatile organic compounds VOCs , which are claimed to produce ground level ozone under certain extreme weather conditions.

But they belong to the 26 declarable allergenic fragrances and must therefore be reported separately because some people are allergic to individual ingredients. Listed perfume in the INCI is a composition of different essential oils, if we want to preserve the exact composition as a scent secret.

The application of nanoemulsions as a novel delivery system for lipophilic materials, such as essential oils, flavors, and fragrances is one of the growing technologies used in cosmetic, pharmaceutical, and food industries. Their characteristic properties, like small droplet size with high interfacial area, transparent or semi-transparent appearance, low viscosity, and high kinetic stability, make them a perfect vehicle for fragrances, in the perfume industry. They could be a great alternative to water-based perfumes, without alcohol, and solve problems related to the oxidation and low bioavailability of fragrances with other non-alcoholic vehicles of perfumes like pomades or gels. The nano-perfume systems were obtained with a low-energy Phase Inversion Composition; PIC and with a high-energy ultrasound, US method, taking into account the possibility of moving from the laboratory scale to an industrial scale. The optimized nano-perfume formulations, prepared with different methods, yielded the same physicochemical properties stability, medium droplet size of the inner phase, polydispersity, viscosity, surface tension, pH, density. These formulations had a low viscosity and a pH suitable for the skin. Moreover, the obtained results confirmed the protective role of nanoemulsions. The peroxide number measurement POV showed that the tested fragrance compositions had a high chemical stability. The results of the microbiological tests confirmed that the obtained products were free of microbiological contamination and were appropriately preserved.

Fragrances can make us feel a whole range of emotions. They are an important part of our daily lives and how we connect as human beings. From the familiar smell of our loved ones to the welcoming feeling of our homes.
But wearing fragrance well requires a little more skill and finesse. And that tendency you have toward dressing your wrists and then rubbing them together? And, sure, while a bottle of Chanel No.
