Polyherbal Sunscreen Cream: Formulation, Physicochemical Evaluation, And In Vitro SPF Determination - Issue cover

Abstract

Background: Herbal bioactives with antioxidant and UV-protective properties are increasingly favored in sunscreen formulations for their safety and efficacy. This study focuses on the development and optimization of a polyherbal sunscreen cream incorporating Camellia sinensis (green tea), Citrus sinensis (orange peel), Punica granatum (pomegranate peel), Curcuma longa (turmeric) extracts in an oil-in-water emulsion base. Objective: To formulate and evaluate a stable, non-greasy polyherbal sunscreen cream and identify the optimal formulation in terms of SPF, texture, spreadability, and stability. Methods: Three formulations (F1–F3) were prepared using a fixed base of stearyl alcohol, cetyl alcohol, emulsifying wax, olive oil, glycerin, and parabens, with varying concentrations of herbal extract blend (6% to 10% w/w). The creams were evaluated for physical characteristics, pH, viscosity, spreadability, in-vitro SPF, and stability under accelerated conditions (centrifugation, thermal cycling, and long-term storage). Results: All formulations were smooth, yellow-green, optically homogeneous, and free from grittiness. pH values remained skin-compatible (6.05–6.15), and no phase separation was observed during stability testing. F3, containing the highest concentration of polyherbal extract and oil phase, exhibited the highest SPF value of 22.7 ± 0.6, a viscosity of 17,600 ± 210 cP, and a spreadability of 5.2 ± 0.2 cm, indicating a rich texture with high photoprotective capacity. All formulations passed centrifugation and thermal cycling tests and maintained long-term stability over 90 days. Conclusion: Among the three tested formulations, F3 was found to be the most effective due to its superior SPF value, acceptable spreadability, and excellent stability. This study highlights the potential of polyherbal extracts as safe and effective ingredients in natural sunscreen formulations, suitable for further in vivo testing and commercial development.

Formulation and Evaluation of Herbal Sunscreen Lotion Enriched with Natural Plant Extracts

Background: Prolonged exposure to ultraviolet (UV) radiation may result in sunburn, accelerated aging, cutaneous damage, and potentially, carcinoma of the skin. While effective, synthetic sunscreens are frequently linked to dermal irritation and possible toxicity. Herbal sunscreens, formulated with natural, plant-derived compounds, present a more secure and ecologically sound alternative. Objective: To develop and evaluate a herbal sunscreen lotion utilizing plant extracts possessing established UV-protective, antioxidant, and skin-soothing properties. Materials and Methods: Herbal extracts derived from Aloe vera, Watermelon, Sandalwood, and Turmeric were selected based on their photoprotective and antioxidant capabilities. The lotion base was prepared utilizing conventional emulsification methodologies. Physicochemical properties, including pH, viscosity, spreadability, and stability, in-vitro sun protection factor determined via UV spectrophotometry were evaluated for the formulated herbal sunscreen lotion. Results: The herbal sunscreen lotion exhibited acceptable spreadability, stability under diverse storage conditions, and an appropriate pH (5.5–6.5). Confirmation of effective UV-B protection was established by the moderate range (SPF 15–25) of the in-vitro SPF value. The presence of significant antioxidant activity suggested the potential for skin protection from oxidative damage. Conclusion: The herbal sunscreen cream exhibits potential antioxidant properties in conjunction with ultraviolet (UV) protection. It serves as a safe, natural, and efficient alternative to chemical sunscreens, demonstrating commercialization potential.

Phytochemical Screening and Anti-Ageing Potential of Herbal Extracts in A Topical Cream Formulation

Background: Calendula, chamomile, and butterfly pea contain a high concentration of antioxidants that rejuvenate skin and provide relief from irritation. Based on this information, we can assume that extracts of these plants can be used to make a sustainable anti-aging cream as a natural alternative to existing skincare products. Objective: This research aims to formulate a topical cream using extracts of calendula, chamomile, and butterfly pea. The work also includes tests of the phytochemical profile and evaluation parameters of the cream. Materials and Methods: In this study, we assessed the content of flavonoids, phenolics, tannins, saponins, and alkaloids by performing qualitative phytochemical screening on methanolic extracts of Clitoria ternatea, Calendula officinalis, and Matricaria chamomilla. Using standard methods, we emulsified the mixed herbal extracts to produce an oil-in-water cream. Once prepared, the cream formulation was evaluated for organoleptic properties, pH, viscosity, homogeneity, spreadability, and stability under a variety of storage conditions. Results: All three herbal extracts were shown to have significant quantities of phenolic compounds and flavonoids upon phytochemical analysis. Additionally, the formulated cream proved to have desirable organoleptic qualities that include a pH of 4.5- 5.2, stable viscosity, and good spreadability. It also proved to remain homogeneous with no evidence of phase separation or microbial growth over the duration of the 30-day stability study. Conclusion: Anti-aging cream formulation using butterfly pea, calendula, and chamomile extracts exhibited promising physical, chemical, and stability profiles. The phytochemical components support the viability of its use as a natural anti-aging formulation. Further studies to assess its biological efficacy are recommended.

Formulation and Evaluation of Polyherbal Based Shampoo

This study aimed to develop and evaluate a polyherbal shampoo using natural, plant-based ingredients that deliver effective cleansing, conditioning, and scalp compatibility without synthetic additives. In response to growing consumer demand for eco-friendly personal care products, Ayurvedic botanicals such as amla, ginger, hibiscus, aloe vera, bhringraj, senna, and shikakai were selected for their well-documented antimicrobial and nourishing properties. Herbal extracts were prepared via maceration and decoction, followed by phytochemical screening to identify bioactive constituents. Seven formulations (F1–F7) were developed using a gelatin base, incorporating herbal extracts, natural fragrance, gelling agents, and pH regulators. Each shampoo was evaluated for physicochemical and aesthetic parameters, including appearance, pH, viscosity (measured at 26 ± 1°C and 120 rpm using a Labman LMDV60 viscometer), foam generation and stability, total solids, dirt dispersion, and washability. Among all prototypes, Formulation F5 demonstrated superior performance: pH of 5.16, viscosity of 946.0 mPa·s, foam stability of 90 mL after 1 minute, and solid content of 23.88%. It effectively dispersed ink and rinsed cleanly, while also exhibiting favorable sensory attributes such as pleasant aroma, golden honey color, and commercial-grade texture. These results confirm that combining multiple herbal extracts in a single formulation can yield a safe, effective, and sensorially appealing shampoo. Formulation F5 stands out as a promising eco-conscious alternative to conventional shampoos, supporting further innovation in herbal-based personal care products.
