Extraction
To obtain oils from plant materials steam distillation is typically used. Solvent extraction is also used to create a resinoid (resembling characteristics of resin). Solvent extraction is commonly used with volatile substances that may be lost with distillation. Solvent used are pentane, hexane, and mixes of solvents such as ethyl acetate and hexane which is commonly used in place of benzene (see Figure 2).
Gas-Liquid Chromatography
Gas-Liquid Chromatography is the process of separating complex mixtures into the components and measuring the individual components. By using injectors, columns, and detectors researchers are able to enhance the separation and identification of the components.
Headspace Collection
The volatile compounds of a fragrance can be found in the headspace, the air above and around a fragrant substance. This technique is mainly used when trying to collect the fragrance from flowers. Absorbent traps are used to collect the volatiles. Traps are small glass tubes containing activated charcoal. The air is ran through the tubes where the volatiles are collected from the flower which is enclosed inside a bell jar in order to prevent the volatiles from being taken away by the air. Once the traps are removed the traps must be kept cool and dark because of the reactive glass and absorbent surfaces that can cause materials to be ruined (Sells, 2006, p. 225).
Chemical Synthesis
The need for several flavors and fragrances exceeds the amount that is made naturally. The annual amount of vanillin used is 12,000 tons however only 1,800 tons of natural vanillin is produced (Crasto, 2012). Therefore, the extra amount needed is produced through chemical synthesis. The most recent and popular form is a two-step p...

There are over a thousand ingredients that are used in cosmetics that are already proven to be safe for human use. These ingredients can be mixed and matched creating new and unique products. Many people argue that this is not suitable for the demanding market. The craving for "new" and "im...
We all know that cosmetics existed thousands of years ago. Cleopatra used a heavy arsenal of beauty aids to help her shake the foundations of the Roman Empire. Yes, cosmetics and perfumes have a long history, but the consumer industry we live in is relatively recent, a creation of the decades 1890 through 1920. The products hawked in the 19th Century by druggists, perfumers, barbers, physicians, and a colorful assortment of other enterprising individuals were primitive by our standards. Certainly, active ingredients were used with abandon, notably arsenic, lead, and mercury. These were products that really made visible differences, and the consumer was well-advised to be wary of the majority of these mysterious concoctions.
In Lynda Barry’s Common Scents, she considers scents a demon for many reasons. One reason being that everyone has his or her own scent preference and scent in general, yet we also judge the way that other people smell. When the woman whose house smelled like a fresh bus bathroom talking about the smells of different Asian people’s houses, Lynda notes that she was “free with her observations about the smells of others” (18). She sprays her house with disinfectant sprays and air fresheners, which to her smells better that whatever her house smelt like before, but to others, such as Lynda’s grandmother, these smells are too strong and are trying to hide the fact that not everything smells good all the time.
The company additionally makes the smells of bath soaps, deodorants, and floor wax. Schlosser reports, “The basic science behind the scent of shaving cream is the same as the that governing the flavor of you TV dinner, in that the aroma of food can be responsible for as much as 90% of its flavor,” (Schlosser 122). Schlosser reveals that in the mid-nineteenth century the processed food industry began expanding increasing the need for flavor additives. (Schlosser 123). The demand for color additives began to grow as well when it was learned that appearance can
The first group of chemical compounds to be discussed are terpenes. Terpenes are a very comprehensive group of metabolites which are known to contain essential oils that produces well-known scents in herbs belonging to the Lamiaceae plant family (Scott 2008). These scented compounds are usually found in the trichomes of basil, rosemary, lavender, etc. (Scott 2008). Electron micrograph images of these trichomes can be seen below. According to Keeling & Boltmann (2006), there are about 30 000 known types of terpenes which originated from structures created from terpene synthases. These terpene synthases can be broken up into three groups, monoterpene synthases, sesquiterpene synthases, and diterpene synthases (Keeling &...

The novel Perfume: The Story of a Murderer, by Patrick Süskind takes place in the densely populated and repugnant slums of 18th century Paris where protagonist Jean-Baptiste Grenouille resides as a lowly peasant with an incomparable sense of smell that sets him apart from the rest of the world. However, Grenouille is unaffected, and endures the hardships of brutal peasant life with an iron will, in the hopes of discovering every scent the world had to offer as his only motivation for living. He craves to be alone to further enhance his knowledge in capturing scent; Grenouille becomes so estranged and enthralled in the art of capturing fragrances that he sets out on a quest to concoct the “ultimate perfume” which leads him to commit a series of murders to capture human scent. Süskind, by way of Jean Baptiste’s obscure life and fine nose allows readers to explore the concept of alienation and the effects it has on the character development of Jean Baptiste Grenouille.

Customers are becoming more and more aware of harmful chemicals in any product but especially in cosmetics. In the article, “Development of a Natural Ingredient – Natural Preservative: a case study” author Audrey Kerdudo discusses what it means for consumers to be changing into environmentally conscious people. Kerdudo begins her study by stating, “Lately, the cosmetic and personal care market has been more and more driven toward natural ingredients by the rising consumers' awareness about personal health and safety and their will for safer cosmetics free of harmful chemicals” (Kerdudo, 2016). This impacts perception because consumers are changing the way they perceive products overall, but specifically in environmentally friendly
