During the last decades, due to their ability to produce a very wide variety of molecules, plants have attracted a growing interest for research in cosmetics. The recent development of green technologies allowed the use of renewable raw materials and the development of new extraction processes more compatible with the rules of sustainable development. However, the use of plants is far from being a novelty. Human have historically exploited plants for their food, health or well-being, using, sometimes unknowingly, “basic chemistry processes” to extract bioactive ingredients.
Although there has long existed a pharmacopoeia that lists plants for therapeutic use, work in the field of traditional cosmetics is still poorly documented. From this observation, the concept of a cosmetopoeia was proposed to fill this gap. Thus, like the pharmacopoeia, the cosmetopoeia will be a register of the cosmetic use of plants.
This Group "Cosmetopoeia, from the traditional to the recent uses of plants in cosmetics" will focus on different aspects including (but not restricted to):
- Traditional uses (the new concept of ethnocosmetology) of plants, for the better knowledge and preservation of the traditional uses of plants in cosmetics.
- Rationalization of the biological activities of traditionally used plants and/or plant extracts using modern techniques.
- Development of new innovative and green extraction processes of bioactive ingredients from plants traditionally used for cosmetics.
These subjects will be developped in the following Special Issue of Cosmetics (MDPI):
(Deadline for manuscript submissions: 31 December 2019)
The use of plant in vitro (bio)technologies offers an attractive alternative for the production of plant-based active ingredients. Plant cells are small factories able to synthesize an exceptional variety of commercially important phytochemicals used as flavors, dyes, pharmaceuticals, nutraceuticals, cosmeceuticals, etc. Conventional plant propagation techniques are subjected to variety of pests, environmental challenges and poor management practices that adversely affect the quality and yield of these valuable phytochemicals. Plant in vitro culture platform offers considerable advantages and advancements over conventional phytochemical production techniques. However, during culture development, the yield of metabolites is generally low due to poor understanding of various factors that affect the biosynthetic pathway. Therefore, various strategies have been developed and reported to enhance biosynthesis of these phytochemicals in plant cell cultures. The recent emergence of omics technologies, molecular biology, metabolic engineering and synthetic biology has revolutionized diverse fields in life sciences. These modern aspects of life sciences have considerably influencing plant in vitro technology and phytochemical production. An application of these technologies is expanding horizons for an understanding of metabolic pathways involved in the biosynthesis of valuable biologically active ingredients and their cost-efficient production.
Materials processing is the first, and a key, step in proper utilization of the composition of a given material and to realize the microstructural features that are intended to attain desired property levels for a given application. Both primary and secondary processing methods are equally important in tailoring the end properties of materials. In view of the crucial importance of the processing of materials, this Special Issue is intending to cover all innovative aspects of primary processing (solid phase, liquid phase, two phase, 3D printing, rapid solidification, etc.) and secondary processing (such as variations in extrusion, forging, rolling, equichannel angular extrusion, etc.) of materials (polymers/ metal/ceramic-based, including their composites). Desirable attributes expected for submission will be processing–microstructure–property interrelations.

To enhance the journal, sensors could present something like the News & Views of nature journals only in a different manner. In sociology sensing means to go straight to the bottom of something in the sense “to uncover the truth”. Hence, one could develop two branches: (1) Very critical contributions asking about the real impact of former findings, inventions or prevailing opinions some years later? For example what impact have had very promising physical effects or technological or achievements in our daily life? (2) Very speculative contributions risking a view into the future, e.g. something along the line /Is graphene the sensing top matter in 2050?/ Alternatively, the prediction of relatively new topics like memristors for human life in future and so on. These aspects, which are not related to a senor in the sense of a hardware component could attract many other readers or authors and would work in natural sciences as well as in humanities but will change sensors original focus.
