Dynamic mechanical analysis of novel cosmeceutical facial creams containing nano‐encapsulated natural plant and fruit extracts

Abstract

Background Cosmetic industry following the recent trends in the relative market has turned its interest in the formation of cosmeceutical products containing natural bioactive ingredients. Natural extracts may reveal undesirable sensory characteristics due to their composition. Encapsulation and nanotechnology are the most promising methods to overcome these drawbacks, opening up new perspectives for the future of cosmeceutical industry. Aims The purpose of this study was the use of nano‐encapsulated plant and fruit extracts to formulate cosmeceutical facial creams with acceptable rheological characteristics. Methods Electrohydrodynamic process was used to encapsulate pomegranate and tea tree oil extracts and incorporate them in facial cosmetic creams. All the formulations including those without additives, were stored at three different temperatures. Subsequently, rheological oscillatory tests (frequency sweep tests) were performed using the dynamic mechanical analysis method in order to evaluate alterations in storage modulus (G'), loss modulus (G''), and complex viscosity (η*). Results Dynamic mechanical analysis, showed that all formulations are suitable for application in cosmetic industry, while changes due to storage period or the storage temperature were negligible. Conclusion The addition of the selected extracts' nanofibers to formulate cosmeceutical facial creams, developed products with acceptable rheological characteristics that could be decisive for the cosmetics industry.

“…[2] There was also an increase in the demand for cosmeceutical products -cosmetics with the incorporation of bioactive compounds, which have therapeutic benefits in addition to the usual actions. [3] Cosmeceutical formulations must combine the aesthetic properties of a cosmetic with the effectiveness of a dermatological medicine; [4] they can act on skin DOI: 10.1002/ejlt.202100168 protection, whitening, with anti-aging and anti-wrinkle action. [5] Several natural bioactive compounds have the potential for use as cosmeceutical ingredients, [6,7] such as phenolic compounds, vitamins, terpenoids, steroids, and polyunsaturated fatty acids.…”

Nanocarriers as Active Ingredients Enhancers in the Cosmetic Industry—The European and North America Regulation Challenges

“…Therefore, to take advantage of all of their biological properties, it is necessary to overcome the above-described problems, which is through encapsulation into nanocarriers such as liposomes [ 53 ]. Furthermore, Kalouta et al [ 54 ] showed that the undesirable sensory characteristics of natural extracts can be overcome by nanoencapsulation, allowing them to be incorporated in cosmeceutical facial creams. Cycloastragenol is a saponin plant that acts as a telomerase activator and has been used as an oral anti-aging supplement and as an active ingredient in topical cosmetic formulations.…”

“…On the other hand, nanotechnology provides delivery systems that can be more effective than conventional excipients or permeation enhancers for impelling actives of cosmeceutical interest into the SC, or even deeper, using the topical route 1,2 …”

“…On the other hand, nanotechnology provides delivery systems that can be more effective than conventional excipients or permeation enhancers for impelling actives of cosmeceutical interest into the SC, or even deeper, using the topical route. 1,2 The transport of certain cosmetic actives by this route may be of particular interest in the case of molecules such as antioxidants of natural origin, 3 since the dietary consumption of their natural sources is not enough to achieve an effective biodistribution in the skin, since intestinal absorption is counting for 1% and that these compounds are also rapidly metabolized by the body. 4 The success of these compounds lies in their presence in the viable epidermis and dermis to exert their protective action in situ.…”
