“…It may be due to the distinct mode of interaction with CTAB‐rich mixed micelles, which retain an overall balance among ionic‐hydrophilic and hydrophobic‐hydrophilic group interactions. Literature studies (Drach et al, ; Husson and Luzzati, ; Lindblom et al, ; Singh et al, ) support our abovementioned observations. This analysis may assist our findings that hydrophilic‐ionic interactions predominate with an increase in the concentration of SDS in the mixture.…”

“…This may be explained by the fact that more structured water molecules surrounding the hydrophobic tails of the surfactants are released when the hydrophobic tails get involved in the micelle formation and are no longer in contact with bulk water. These facts get support from the studies reported by various workers (Alauddin et al, ; Chen et al, ; Drach et al, ; Dubey, ). This phenomenon may be termed as the release of hydrophobic hydration of ionic amphiphilic monomers.…”

“…The chief role of ʟ‐ascorbic acid (vitamin C) is its immune‐stimulating effect as it provides defense against infections such as the common cold (Banipal et al, ; Davies et al, ). ʟ‐Ascorbic acid is a renowned antioxidant, free radical scavenger, improves the eye's capability, and hinders the development of advanced age correlating the muscular degeneration (Drach et al, ; Roy et al, ). The systems containing surfactants and ʟ‐ascorbic acid may act as models for understanding the interactions and action mechanisms in multicomponent biological systems (Harutyunyan et al, ).…”

“…Some researchers (Drach et al, ) have assessed the antioxidant behavior of ʟ‐ascorbic acid in sodium dodecylsulfate (SDS) micellar systems. However, the physicochemical (conductivity, volumetric, and compressibility) and spectroscopic (UV–vis, NMR, and DLS) studies on the interaction between mixed (SDS + cetyltrimethylammonium bromide [CTAB]) surfactants and ʟ‐ascorbic acid are not available in the literature as a function of temperature.…”

Surfactant micelles mimic the microenvironment present in biological systems and can act as a medium for antioxidant studies. Moreover, the thermodynamic profile of micellization and spectroscopic studies provides very good information about interactions in these systems. Thus, the mixed micellar behavior of sodium dodecylsulfate (SDS) and cetyltrimethylammonium bromide (CTAB) at varying mole fractions of SDS was studied in (0.01, 0.02, and 0.03) mol kg−1 ʟ‐ascorbic acid(aq) solutions with the aid of various techniques viz., conductivity, density and sound velocity, and spectroscopy. From the CMC values of the mixed surfactants, the degree of ionization (β) and thermodynamic parameters (normalΔGm°, normalΔHm°, and normalΔSm°) were evaluated at 298.15, 308.15, and 318.15 K. The UV absorption spectra were recorded in (1–3) × 10−4 mol kg−1 ʟ‐ascorbic acid(aq) solutions at various mole fractions of SDS. The proton (1H) NMR spectra of mixed (SDS + CTAB) surfactants were studied in (0.01–0.03) mol kg−1 ʟ‐ascorbic acid solutions. Hydrodynamic diameters (Dh) of mixed micellar aggregates were obtained from the dynamic light scattering (DLS) studies. The present studies suggest the predominance of ionic‐hydrophilic interactions between the ionic head groups {O‐SO3− or N+ (CH3)3} of surfactants and the polar (–OH, –C=O and –O–) sites of ʟ‐ascorbic acid.

“…Experiments show that the antioxidant activity of vitamin C involves a hydrogen transfer rather than an electron transfer. In vitro, vitamin C behaves as an efficient antioxidant in several different ways such as reducing lipid peroxidation and scavenging peroxyl, thiyl, sulphenyl, urate, nitroxide, and other radicals (32). Thus, we conducted the evaluation of scavenging activity of ABTS and DPPH and iron reduction capacity of vitamin C as a standard to compare with the results for PPE.…”

Abstract. Pimenta pseudocaryophyllus is a Brazilian native plant that presents high concentrations of flavonoids and other polyphenolic compounds. Herein, we evaluated: (1) the chemical properties of P. pseudocaryophyllus ethanolic extract (PPE), (2) the in vitro antioxidant activity (AA) of PPE and of two different topical formulations (F1 and F2) containing PPE, (3) physico-chemical and functional stability, (4) in vitro release of PPE, and (5) in vivo capacity of formulations to prevent UV-B irradiation-induced skin damage. Results show that the polyphenol and flavonoid contents in PPE were 199.33 and 28.32 mg/g, respectively, and HPLC results show the presence of eugenol, tannic acid, and rutin. Evaluation of the in vitro AA of PPE demonstrated a dose-dependent effect and an IC 50 of 4.75 μg/mL in 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 3.0 μg/mL in 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. The ferric-reducing antioxidant power (FRAP assay) was 0.046 μmol/L trolox equivalent/ μg/mL of extract. Among the AA, only the capacity to scavenge DPPH radical of PPE was maintained in F1 and F2. In addition, both formulations satisfactorily released the extract. The evaluation of the functional stability of F1 and F2 did not demonstrate loss of activity by storage at room temperature and at 4°C/6 months. In irradiated mice, treatment with F1 and F2 added with PPE significantly increased the capacity to scavenge ABTS radical and the FRAP of skin compared to vehicle-treated mice. In conclusion, the present results suggest that formulations containing PPE may be a topical source of antioxidant compounds to decrease oxidative damages of the skin.
