Objective: The objective of the study was to obtain a lotion foundation using epigallocatechin gallate (EGCG) as an active ingredient designed with asun protection factor (SPF) value around 30 that can effectively protect facial skin from ultraviolet radiation (UVR) exposure and that is safe to use.Methods: In this study, we determine SPF value using UV–visible spectrophotometry at a wavelength between 290 and 320 nm. The preparationformula of the foundation was made with an EGCG concentration of 0.4%, a concentration which can yield the desired SPF value of about 30. Physicalstability was performed at low (4±2°C), ambient (25±2°C), and high (40±2°C) temperatures; cycling and centrifugation tests were also conducted.Safety was evaluated by eye irritation test using hen’s egg test on chorioallantois method and skin irritation test using the Draize and patch testsmethod.Results: The SPF values of 0.04% EGCG and lotion foundation containing 0.4% EGCG were 31.02±0.72 and 33.20±0.59, respectively. The results ofcycling and centrifugal tests indicated that lotion foundation showed an absence of crystals and lack of any phase separation between oil and waterphases. The physical stability test showed no significant changes for all parameters. Safety tests resulted in neither skin nor eye irritation.Conclusion: The EGCG foundation developed was physically stable with a good appearance and did not irritate the skin or eyes thus are safe to usealso can effectively protect skin against UVR exposure.

Objective: The purpose of this study was to determine the safety, physical stability, and hair growth activity of ethanol extract of licorice.Methods: In this study, 2.5%, 5%, and 10% licorice extract was formulated into a hair tonic as a tonic is easier to use and is not sticky like a semisoliddosage. The hair growth activity test was conducted by rubbing the hair tonic preparations on rabbit’s backs; subsequently, the hair length, hairthickness, hair weight, and hair density were measured. Quantitative analysis of glycyrrhizic acid from the licorice ethanol extract with a ultravioletspectrophotometer showed a level of about 156.65 mg/g or 15.665%. The physical stability test was performed on samples of the tonic stored at low(4±2°C), room (25±2°C), and high (40±2°C) temperature, and a cycling test was also performed. The safety test was performed using an eye irritationtest that employed the Hen’s egg test–chorioallantoic membrane (HET-CAM) method and a skin irritation test that employed the patch test method.Results: The hair tonics containing 5% and 10% licorice extract had an equivalent activity of hair growth and even better than the positive controlcontaining 2% minoxidil. The physical stability test showed that the licorice extract hair tonic has good physical stability. The results of the safety testshowed no skin irritation, whereas the HET-CAM test showed that the hair tonic containing licorice extract showed mild eye irritation.Conclusions: Licorice ethanol extract hair tonic solutions in concentrations of 2.5%, 5%, and 10% had hair growth activity similar to that of thepositive control (minoxidil). They have a good physical and chemical stability, also safe for topical use, except the 2.5% licorice ethanol extract hairtonic solution which caused mild eye irritation.

A three-factor three-level Box-Behnken design(BBD) was employed to optimize capsaicin-loaded nanoparticles(Cap-NPs), and its properties in vitro and in vivo were evaluated. Particle size, morphological characteristics, entrapment efficiency of Cap-NPs were investigated respectively by Zetasizer, H7000 TEM and HPLC. Release, skin permeation and skin irritation test were investigated on mouse and rabbits. The predicted values of Cap-NPs were 94.50±6.33% for entrapment efficiency(EE) and 170.30±7.81 nm for particle mean diameter(PMD) under optimal conditions which were 346.33 bar (homogenization pressure, X1), 4.67 min(homogenization time, X2), and 15421.42 rpm (shear rate, X3). The in vitro permeation study showed that capsaicin permeability in NPs-gel was a 2.80-fold greater flux values than conventional ointment after 24 h. Cap-NPs-gel produce no observable skin irritation in rabbits within 72h. The optimized Cap-NPs-gel would be a good candidate for transdermal delivery.

1 The limitations of the Draize rabbit skin irritation test for hazard evaluation for man are widely documented. Nevertheless it remains the prescribed method for deter mining acute skin irritation hazard. 2 While the use of human testing for risk assessment of irritants is well established, the use of predictive testing in man for hazard identification has not been explored widely, and this is the object of the research programme. 3 The experiment described in this report evaluates the sensitivity of four patch testing systems (Finn chamber, Hill Top patch, Van der Bend chamber, and Webril patch) using a total of six irritant substances. 4 Following preliminary range-finding experiments, test materials were applied to the upper outer arm for up to 4 h. Assessments were performed immediately after patch removal and at 1, 24, 48 and 72 h. 5 Webril and Hill Top patches generated the greatest lev els of response, although responses with Finn and Van der Bend were observed. Hill Top patches are recom mended for future development work. 6 The use of very small preliminary panels to predict the effects in larger panels using different volunteers was only of limited value as each volunteer was found to have different irritant thresholds.
