Cosmetic Formulation Strategy: From Raw Materials to Packaging by Nanotechnology and Nanobiotechnology's Processes

Dear Colleagues,

Cosmetic Science is a highly diversified scientific field, where the different ingredients used to formulate a cosmetic product, with their various mechanisms of action, meet the complex biological systems of skin and its appendages and of mucous membranes. Thus, the cosmetic scientist needs not only to know the physicochemical characteristics and functionalities of the chemicals and natural ingredients used to formulate a certain cosmetic, but also to recognize or forecast the possible interactions occurring when these ingredients are emulsified or otherwise combined and blended. Moreover, the cosmetic scientist should have a deep knowledge of the skin and mucous membranes, as the formulated products are finally applied on these biological structures with the aim of "cleaning, perfuming, and changing their appearance to keep them in good conditions", according to the EU rules. All the selected ingredients need to be effective and skin-safe. For this purpose, a deep knowledge of the methodologies used to control the effectiveness and safety of both ingredients and final formulation have to be part of the chemist/biochemist learnings. Finally, the cosmetic formulator should be acquainted with the raw materials used to produce the primary and secondary packaging, in order to avoid the release of toxic compounds from the container into the content. Last but not least, it is necessary that both the primary and secondary packaging materials should be biodegradable and environmentally friendly. All this extended culture should be combined with a deep involvement in R&D investigation.

The cosmetic market growth is characterized by constantly innovative products and tools, as continuously requested by customers and consumers. For this reason, nanotechnology- and nanobiotechnology-based ingredients are becoming fundamental components of many cosmetic formulations. Because of the growing request of natural products, nanobiotechnology is the actual emergent field of nanotechnology. This is due to its ability to integrate biotechnology on the nanoscale interfacing with biological and natural systems. This Special cosmetic Issue has the aim to introduce the reader to the fascinating field of nanotechnology and nanobiotechnology in the cosmetic sector, whose application is increasingly necessary to produce innovative products, while trying also to solve the issues and meaning of the so-called natural and bio-cosmetics.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cosmetics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
