Abstract

Lipophilic antioxidants such as β-carotene and astaxanthin have strong potential to protect the skin against oxidative stress; however, their topical application is limited by low stability and insufficient skin penetration. This study aimed to formulate and evaluate the physical characteristics, stability, and antioxidant activity of a nanoserum combining carrot extract (Daucus carota L.) and astaxanthin. Carrot extract was obtained by maceration using 96% ethanol and formulated into a nanoemulsion-based serum containing three extract concentrations: 5% (F1), 10% (F2), and 15% (F3), with 1% astaxanthin. The formulations were evaluated for organoleptic properties, particle size, polydispersity index (PDI), zeta potential, pH, viscosity, and adhesiveness. Stability was observed up to 6 days, while antioxidant activity was determined using ABTS and FRAP assays. All formulations exhibited nanoscale particle sizes with good homogeneity (PDI <0.5) and negative zp (<-30 mV), indicating stable dispersions. Formula F2 showed the most favorable characteristics, with a particle size of 39.21 ± 0.32 nm, PDI of 0.25 ± 0.02, and zeta potential of −33.66 ± 0.27 mV, along with suitable pH and viscosity for topical application. F2 demonstrated very strong antioxidant activity, with IC₅₀ values of 9.04 ± 0.19 ppm (ABTS) and 16.78 ± 0.04 ppm (FRAP), which remained in the strong category after storage. In conclusion, the carrot extract–astaxanthin nanoserum was successfully developed, with F2 identified as the optimal formulation.

Abstract

The present study was conducted to assess the acute oral toxicity of a copigment complex formulated from extracts of black rice (Oryza sativa L., indica) and soybean (Glycine max (L.) Merr.). Despite extensive individual pharmacological investigations of these botanical sources, no safety data have previously been documented for their combined copigment complex intended as a functional beverage constituent. Following the Acute Toxic Class methodology (OECD 423), the complex was orally administered as a single dose at 300, 2000, or 5000 mg/kg body weight (BW) to female Swiss Webster mice (n=3 per dose group), alongside a vehicle control group administered 1% Na-CMC. A comprehensive 14-day monitoring program assessed mortality, a range of clinical indicators (including tremor, convulsions, salivation, diarrhea, lethargy, locomotion, coat condition, and ocular appearance), and body weight at Days 0, 7, and 14. No animal deaths occurred across any group. Transient, mild hypoactivity was noted in animals receiving 5000 mg/kg at 1–2 hours post-dose, which resolved completely by 4 hours post-administration. No additional adverse clinical manifestations or weight loss were detected. Based on these findings, the median lethal dose (LD50) is projected to surpass 5000 mg/kg BW, corresponding to GHS Category 5 (practically non-toxic). The results collectively establish a safety foundation for the use of this copigment complex as a functional ingredient in isotonic beverage products, while acknowledging the need for further subchronic and chronic toxicological investigations.
