To answer this question, the formulator must understand the basic principles of fragrances and how they are employed in personal care products. This chapter introduces the beginner to fragrance chemistry and how these compounds are used in formulations.  \nHow Fragrances Are Created  \nBeginning the creative process: Simply stated, fragrances are compounds added to personal care products to improve their odor or to create a certain aesthetic impression on the user. They are created by specialized companies known as“fragrance houses” that consist of perfumers, chemists, evaluators, marketers and other trained professionals. Fragrance suppliers work with product manufacturers to develop new fragrances in a process that can take many paths. In some cases, the fragrance house can proactively develop scents based on their internal knowledge of trends in the marketplace. In other instances, they may develop a fragrance following specific guidelines established by the client company.  \nThe key attributes desired by the client may be summarized in a document known as a fragrance brief (See Sidebar 18.1 Example Fragrance Brief ). The brief establishes the project objective, the conceptual direction, and the cost constraints. It also describes the type of product that the fragrance will be used in and what kind of testing will be required to validate the acceptability of the fragrance. Many larger companies use a dedicated liaison, known as a fragrance coordinator, who deals with the fragrance houses and facilitates this creative process.  \nFragrance Descriptions: Table 18.1 shows how we plan to execute the four variants.  \nFragrance Vocabulary  \nBefore understanding fragrance chemistry it is helpful to understand some of the terminology used to describe fragrances. Some key terms are defined below.  \nAccord: A combination of several fragrance notes used as a backbone around which the rest ofthe fragrance is built.  \nBalanced: A fragrance whose components have been so carefully blended together that no single aromatic body or effect is readily identifiable.  \nBody: Containing complex overtones and “color;” a fragrance lacking body is considered to smell “thin.”  \nCharacter: The distinct impression the fragrance gives (fruity, floral, green, etc.)  \nDiffusion: The degree to which a fragrance radiates from the product or from the user after application of the product.  \nEssential oil: A volatile oil obtained from a specific botanical; typically smells reminiscent of the parent plant or flower.  \nIFRA: The International Fragrance Association, a non-profit organization that issues recommendations on the limitations of fragrance ingredients based on safety data.  \nLift: The impact of a fragrance. Highly diffusive fragrances exhibit good lift.  \nStrength: The relative intensity of a fragrance impression.  \nSynthetic: Either derived from natural products or manufactured from coal tar derivativesand other chemicals. Synthetics maybe of amore uniform quality than their naturally derived counterparts.  \nVolatility: The degree to which a component freely diffuses into the atmosphere.  \nSidebar 18.1.
