Abstract

Nanomaterials are systems with at least one external dimension in the size range of approximately 1–100 nm (or 10−9–10−7 m). Nanoscale modifies the chemical, physical, and biological properties of the raw material, resulting in a wide diversity of applications, for example, drug delivery, diagnostics, implants, biosensors, medical imaging, and tissue engineering. Among the cosmetic and galenic formulations for topical administration, nanomaterials are being employed with the purpose of protection of the active pharmaceutical ingredient (API) from degradation, to improve the local action and to avoid the API penetration into the bloodstream, thus reducing the risk of systemic effects and toxicity. The most popular nanomaterials for topical application are based on lipid or polymeric nanoparticles, while others containing metals are mainly used for diagnostic purposes and imaging analysis. Of particular relevance are those composed of biodegradable and biocompatible raw materials (so-called nanobiomaterials), making them attractive for the formulation of topical pharmaceuticals and cosmetics. This chapter summarizes the recent advances in nanobiomaterials and their applications in galenic and cosmetic formulations.

    In the cosmetic industry, Polysaccharides-based natural polymer plays a crucial role as a film-forming, emulsifier, stabilizer, rheological modifier, etc. [29]. Cosmetics products in the market generally use synthetic-based polymers such as silicon, polyacrylamides, alkylene oxide, polyamide, polyether, polyvinyl alcohol (PVA), polyester, etc. [30]. The small quantity of synthetic polymer is safe in cosmetics products.

    In most cases, the inner core accommodates the bioactive agent, while the polymeric counterpart controls its release. Nanospheres are composed of a polymeric matrix, in which numerous active ingredients can be entrapped or into which they can be adsorbed [54,55]. A large variety of hydrophilic and hydrophobic molecules can be loaded into these NPs, but they are mainly employed to improve the performance of chemically labile (e.g., antioxidants and retinoids), poorly water-soluble (e.g., organic filters) and volatile (e.g., fragrances) agents [56].
