The Scent of Change: Sustainable Fragrances Through Industrial Biotechnology

Current environmental and safety considerations urge innovation to address the need for sustainable high-value chemicals that are embraced by consumers. This review discusses the concept of sustainable fragrances, as high-value, everyday and everywhere chemicals. Current and emerging technologies represent an opportunity to produce fragrances in an environmentally and socially responsible way. Biotechnology, including fermentation, biocatalysis, and genetic engineering, has the potential to reduce the environmental footprint of fragrance production while maintaining quality and consistency. Computational and in silico methods, including machine learning (ML), are also likely to augment the capabilities of sustainable fragrance production. Continued innovation and collaboration will be crucial to the future of sustainable fragrances, with a focus on developing novel sustainable ingredients, as well as ethical sourcing practices.     

Behavioral Foraging Responses by the Butterfly Heliconius melpomene to Lantana camara Floral Scent

Floral color has been shown to influence flower selection by butterflies, but few studies have investigated the role of floral scent. In this study, adults of Heliconius melpomene L. (Lepidoptera: Nymphalidae: Heliconiinae) were tested in two-choice bioassays to investigate their ability to distinguish floral scent of the butterfly pollinated plant Lantana camara L. (Verbenaceae) from other plant scents. The relative importance of floral scent vs. color was also studied. Butterfly foraging behavior was measured as probing with proboscis. This probing, on floral models varying in scent and color, was timed. When given a choice of floral and vegetative scents of L. camara, newly emerged butterflies preferred floral scent, indicating an innate response to floral scents. When butterflies were conditioned to L. camara floral scent by offering the scent with yellow color and sugar water, yellow color elicited stronger feeding responses than did the floral scent. However, the floral scent of L. camara was preferred to that of the novel species Philadelphus coronarius L. (Hydrangiaceae). The floral scent of L. camara was dominated by tepenoid compounds, while that of P. coronarius by fatty acid derivatives, thus demonstrating totally different compositions. It is concluded that, while H. melpomene butterflies often use visual floral traits when selecting which flowers to visit, floral scents elicit behavioral responses that initiate and maintain foraging on flowers.     

Gas chromatographic analysis of fragrances in palm-based white soaps

Four commercial soap fragrances 1,2,3, and 4 were incorporated in palm-based white soaps and made into bars. The soap bars were stored at 25°C and 40°C for three months. The headspace gas-chromatographic volatiles, fragrance odor intensity and whiteness analyses of the soap samples were carried out at 10-day intervals. By means of gas chromatography and mass spectrometry, some of the headspace gas-chromatographic peaks were identified. These peaks were useful in monitoring the fragrance components. For example, fragrance 4 contains the components limonene and citronellal which are known to possess a citrus odor component. Fragrance odor intensity scores showed that the intensity of the fragrances in the soap base was the same for all. Results also showed that most of the fragrances had the same effect on the whiteness of palm-based white soaps, except for fragrance 2 which gave a pink color to the white soaps. Equations were established between the fragrance odor intensity and area under the gas-chromatographic peaks. The equation can give useful information on the fragrance odor intensity by calculating the area of the chromatographic peaks; the fragrance odor intensity is a reflection of the fragrance retention in palm-based soaps.     

香气共振理论

把各种香料按蒸气压大小分为＂头香香料＂、＂体香香料＂和＂基香香料＂三组,计算香精和香水中三组香料的总蒸气压。如果以＂头香香料＂与＂体香香料＂蒸气压之比为A,＂体香香料＂与＂基香香料＂蒸气压之比为B,＂基香香料＂总蒸气压为C,当A∶B∶C=m2∶m∶1时,则认为该香精或香水符合共振结构。具有共振结构的香精香气比较和谐、稳定。香水香精的m值一般为4～6,m值小的留香时间较长;香水的m值一般为500～2 000。     

Can eyes smell? cross‐modal correspondences between color hue‐tone and fragrance family

Color can facilitate the identification of odor quality and influence the perception of odor intensity. To deliver coherent sensory messages of perfumes effectively, this research investigated whether people experience cross‐modal interactions between color hue–tone and fragrance family and how consistent these cross‐modal interactions are. Two experimental tasks were conducted with eight commercial perfumes in four typical fragrance families (floral, oriental, fresh, and woody): direct fragrance–color matching and degree of similarity judgement between color and fragrance. These tasks revealed that fragrances were nonrandomly, consistently matched with colors. The correspondences between the fragrance families and colors were influenced by the hue (warm–cool color images) and tone (especially, lightness property) dimensions. In addition, gender differences in the color–fragrance correspondences were partially revealed for the four fragrance families. On the other hand, there were no significant differences between the degrees of familiarity with the fragrance families and the color–fragrance correspondences. These findings confirm the robust existence of cross‐modal correspondences between vision and olfaction in perfumery. © 2011 Wiley Periodicals, Inc. Col Res Appl, 2013     

A quantitative study of factors that influence the substantivity of fragrance chemicals on laundered and dried fabrics

Model investigations of physicochemical aspects of the substantivity of fragrance raw materials on laundered fabrics were performed. The overall process was divided into two consecutive steps, laundry and dryout, which were characterized by affinity and tenacity, respectively. The affinities of fifteen fragrance raw materials to cotton and polyacrylonitrile were measured in standard fabric softener and detergent solutions. Affinities correlated with the corresponding partition coefficient, P(o/w). To study the impact of parameters independent of the chemical structure of the fragrance molecules, 1-[³H]-3-methyl-5-phenylpentanol (phenylhexanol) was selected, and aqueous solutions of defined anionic, nonionic and cationic surfactants were used as model detergent and fabric softener media. A sequence of experiments, based on the fractional factorial design, was planted for quantifying the relative contribution on substantivity of a number of variables: the concentration of the fragrance chemical, the type and concentration of the surfactants, the type and weight of the fabrics (cotton or polyacrylonitrile) and the washing temperature in the case of cotton. The affinity that characterizes the washing process depends mainly on the type of fabric and the type of surfactant and, to a lesser extent, on the surfactant concentration and the temperature. Anionic and nonionic surfactants, the main components of detergent powders, behave similarly, whereas the combination of cationic surfactant with cotton markedly enhances the affinity. For phenylhexanol, the tenacity after dryout is largely controlled by the type of fabric. The role of fiber swelling is discussed. The substantivity, which represents the global effect of laundering and dryout, shows the same trend as the affinity. The complexity of the physicochemical phenomena involved is highlighted by the importance of the interactions between the main contributing factors.     

Some communicatory functions of scent marking in the cotton-top tamarin (Saguinus oedipus oedipus)

The ability of cotton-top tamarins to discriminate between scents from conspecifics and those from other tamarin species, and between scents from conspecific individuals was tested. Cotton-tops scent mark with specialized skin glands in the circumgenital area. Females possess larger glands than males and show more scent-marking behavior. In the first experiment, subjects were presented with a glass rod scented with either material collected from the surface of the scent glands of a conspecific female, with scent material from a female of a related species, or with an unscented rod. Glass rods carrying scent from conspecifics were sniffed more frequently than rods carrying scent from related tamarin species or unscented rods. A second experiment offered a choice between two glass rods, one scent marked by aSaguinus o. oedipus female, the second one scent marked by aSaguinus fusdcollis female. Shelves carrying rods that had been scent marked by conspecifics were contacted more frequently than those carrying rods marked by heterospecific females. Scent marks from conspecific females were also sniffed more frequently. A third experiment compared the level of responses to rods carrying material collected from the scent glands of female individuals to which the subjects had been habituated with their responses to rods carrying scent from females to which they had not been habituated. Contacting and sniffing responses to the scents of novel females were higher than those to the scents of females to which the subjects had been habituated.
