“…where m parameter represents the viscosity obtained for the shear rate value of 1•s -1 , and n is the flow behaviour index (Dănilă et al, 2019a). As can be seen from Figure 3a-b, the emulsion viscosity decreased at shear rate increase showing a pseudoplastic behaviour at both working temperatures.…”

“…Alongside the m and n parameters described in detail above, another significant rheological descriptor for a dermatocosmetic product is the thixotropy. For a pseudoplastic system, the thixotropy represents a valuable characteristic because it illustrates a modification of the viscosity that is dependent on time [49]. IUPAC defined the thixotropy as a decrease of the viscosity or the consistency of a system after a long rest when a definite shear is applied on the system, with the recovery of the initial viscosity or consistency [50].…”

Cosmeceuticals are one of the fast-growing areas of the natural personal care industry. Cosmeceuticals are cosmetic products with medicinal or drug-like benefits that can affect the biological functioning of the skin depending on the ingredients in the composition. The development of one formulation acting on the dermis and stimulating the collagen production is very important for the hydration of the skin. The association of collagen with other ingredients can have a positive effect on increasing the natural production of collagen in the skin. An example of such an ingredient is niacinamide, which, having a recognized nutritional value, has been quite recently studied. Considering these aspects, this study focused on developing oil-in-water (O/W) emulsions, based on natural ingredients (vegetable oils, floral waters, and essential oils) and hydrolyzed collagen and niacinamide as active ingredients, and on evaluating the stability, pH, optical, superficial, rheological and textural properties, as well as microbiological tests of the emulsions, in order to investigate their potential as a cosmeceutical product. All the obtained emulsions proved to be stable at variable temperatures and had a pH value compatible with natural pH of the skin, allowing their safe application. Over goniometric analysis, a partial wetting and a hydrophilic character of the emulsions were emphasized. Following the rheological analyses, all dermatocosmetic emulsions exhibited non-Newtonian pseudoplastic behavior and a thixotropic character, these properties being very important for their production process and their application on the skin surface to generate an optimal therapeutic effect. The textural characteristics recorded for all emulsions indicated adequate spreadability at the application site. All tested samples respected the Pharmacopoeia limits of microbiological contamination. All prepared emulsions have good stability, are safe for the skin and have appropriate physicochemical and microbiological characteristics; therefore, they can be used as a cosmeceutical product.

“…In terms of conditioning and dissemination on the skin, as well as the establishment of a continuous film at the application site, it is ideal for topical application systems to exhibit pseudoplastic behaviour. At high shear rates, such as when dispensing from the conditioning vessel, the material will flow quickly, thereby facilitating administration, whereas at low shear rates, such as when the product is being spread on the skin, the material will adopt a high viscosity by regaining the rheological properties it possessed prior to administration [19]. According to Martinez et al, [20], the most essential usage sense in these circumstances is spread ability and perceptiveness hence, products displaying shear-thinning, non-Newtonian flow are chosen due to their superior spread ability and perceivability.…”

In the realm of cosmetology, anthocyanin has recently been used as one of the essential ingredients. Anthocyanin has been demonstrated to lessen irritability and aid in moisture retention when applied. However, adding a natural ingredient to a skin care product formulation might alter the consumer's experience when the product is applied since it increases the actual contact area and adhesion, which alters friction. In this study, the chemical and flow characteristics of anthocyanin are examined in order to evaluate the rheological characteristics of butterfly pea flowers that contain anthocyanin. Anthocyanins were derived from three main sources and the characteristic have been compared. By using a shear rate scan test rheometer with a plate configuration and a 1mm gap and temperatures ranging from 25°C to 85°C, rheological data were collected. Utilizing a UV-visible spectrophotometer and Fourier-transform infrared spectroscopy (FTIR), anthocyanin's chemical structure, class, and yield are each identified. It is found that anthocyanins' structural, physical, and functional attributes are generally influenced by their source, composition, and content.
