“…In the field of cosmetic science, viscosity management is of paramount importance, having a profound impact on the overall perceived quality of the product as it determines its consistency and spreadability on the skin [59,60]. This significance is particularly evident in surfactant-based cosmetic systems, where precise viscosity control is a routine and crucial practice in industrial settings.…”

“…Rheological properties are often selected to align with the type of cosmetic product and its impact on the skin. Cosmetics designed for skin regeneration and irritation relief, especially those intended for dry and flaky skin, should linger on the skin's surface for an extended period [60][61][62], and these are commonly provided as creams and serums [63]. In this context, rheological modifiers play a pivotal role in adjusting the viscosity profile to meet desired specifications, thereby enhancing the consumer's experience with the product.…”

The present study aimed to evaluate the possibility of using micellar and solvent loan chemical extraction (LCE) to isolate valuable components from grapevine leaf buds, subsequently utilizing them to prepare functional and safe-to-use cosmetic preparations, specifically facial serums. An aqueous solution of polyglyceryl-4 laurate/sebacate and polyglyceryl-6 caprylate/caprate was employed for a micellar LCE, while an aqueous solution of 1,3-propanediol was used for a solvent LCE. Importantly, the extraction medium was exclusively comprised of components from the designed final cosmetic product. Consequently, no additional substances were present in the cosmetics developed, and the formulation was notably enhanced by compounds extracted from grapevine buds. The antioxidant properties and compound characterization of the obtained micellar (SurfE) and solvent (SolvE) extracts based on grapevine buds were tested and compared. UPLC-MS/MS results indicated that the extracts were rich in phenolic and flavonoid compounds, exhibiting antioxidant activity as measured using the DPPH and ABTS scavenging ability. The extracts were used to prepare model facial serums, which underwent evaluation based on fundamental functionality-related parameters (e.g., rheological characteristics and color) and their impact on the skin through cytotoxicity assessment. The results demonstrated that facial serums with extracts based on grapevine buds provided safe, natural cosmetics.

Comprehensive study of α-terpineol-loaded oil-in-water (O/W) nanoemulsion: interfacial property, formulation, physical and chemical stability

In this study, the interfacial ability of α-terpineol (α-TOH) was reported, followed by its trapping into oil-in-water (O/W) nanoemulsion as active-ingredient and the long-term observation of this nanosystem influenced by the storage-time (410-days) and temperature (5, 25, 50 °C). The results indicated that the α-TOH can reduce the interfacial tension on the liquid-liquid interface (ΔG°m = −1.81 KJ mol−1; surface density = 8.19 × 10−6 mol m−2; polar head group area = 20.29 Å2), in the absence or presence of surfactant. The O/W nanoemulsion loaded with a high amount of α-TOH (90 mg mL−1; 9α-TOH-NE) into the oil phase was successfully formulated. Among the physical parameters, the mean droplet diameter (MDD) showed a great thermal dependence influenced by the storage-temperature, where the Ostwald ripening (OR) was identified as the main destabilizing phenomena that was taking place on 9α-TOH-NE at 5 and 25 °C along with time. Despite of the physical instability, the integrity of both nanoemulsion at 5 °C and 25 °C was fully preserved up to 410th day, displaying a homogeneous and comparable appearance by visual observation. On contrary, a non-thermal dependence was found for chemical stability, where over 88% of the initial amount of the α-TOH nanoemulsified remained in both 9α-TOH-NE at 5 and 25 °C, up to 410th day. Beyond the key data reported for α-TOH, the importance of this research relies on the long-term tracking of a nanostructured system which can be useful for scientific community as a model for a robust evaluation of nanoemulsion loaded with flavor oils.
