Last few decades have witnessed a great demand for herbal cosmeceutical products, because these\r\nherbal and natural cosmeceutical products are safe to use and do not have any side effects. With man\r\nrelearning the benefits of natural products, cosmeceutical products are increasingly being used by\r\nleading herbal manufacturers right from body lotions to face packs, from skin cleansers to fairness\r\ncreams. There has been a metamorphosis in the cosmeceutical industry with natural products being\r\nmore in demand than their synthetic counterparts; this has been possible because of the shift in\r\nconsumer preference from synthetic cosmetics to natural ones. This review gives an overview from\r\ncosmeceutical value of natural ingredients and novel technologies in anti-aging....
Topical formulations (Gel ) have been developed containing Chloroform Extracts of Azadirachta indica, chloroform extract of Ocimum sanctum and methanol Extracts of Curcuma longa and Aloe vera concentrate gel and almond oil. In vitro antibacterial activity was performed against Propionibacterium acnes (P. acnes), a causative organism for Acne vulgaris for the developed formulations using cup plate method. The measured zones of inhibitions of the formulations were compared with standard antibiotic (tetracycline), standard marketed topical herbal preparation for acne. Results of the investigation showed that formulation 1 has greater antibacterial activity (zones of inhibition >19.8 mm) than other formulations and which is comparable to that of standard marketed topical herbal preparation. When compared with chloroform extract of Ocimum sanctum (Zone of inhibition < 17 mm), chloroform extract of Azadiracta indica (Zone of inhibition < 32mm) and methanol Extracts of Curcuma longa (Zone of inhibition 22 mm) all formulations had shown better activity while the activity was found less on comparison with the standard antibiotic solution (zone of inhibition >34 mm). Invivo activity has done for the formulation 1. As physical observations were carried out on regular intervals at the rabbit ear and progressive fading of comedo was found on drug treated animals. No change was observed in control group, where as in test groups shown significant improvement on comedo reduction of rabbit pinnas was observed photographically. Test group showed a significant improvement compared to standard comedo....
Background: Nano-emulsions, as non-equilibrium systems, present characteristics and properties which depend\r\nnot only on composition but also on their method of preparation. To obtain better penetration,\r\nnanocosmeceuticals use nano-sized systems for the delivery of active ingredients to targeted cells. In this work,\r\nnano-emulsions composed of miglyol, rapeseed oil and salmon oil were developed as a cosmetic matrix.\r\nMeasurements of different physico-chemical properties of nano-emulsions were taken according to size,\r\nelectrophoretic mobility, conductivity, viscosity, turbidity, cristallization and melting point. The RHLB was calculated\r\nfor each formulation in order to achieve maximum stability.\r\nResults: Both tween 80 and soya lecithin were found to stabilize formulations. The results showed that rapeseed\r\noil and miglyol are the predominant parameters for determining the expression of results concerning the\r\ncharacterization of emulsion. Based on the mixture design, we achieved the optimal point using the following\r\nformulation: 56.5% rapessed oil, 35.5% miglyol, and 8% salmon oil. We considered this formulation to be the best\r\nas a nanocosmeceutical product due to the small size, good turbidity, and average HLB.\r\nConclusions: This study demonstrates the influence of formulation on the physico-chemical properties of each\r\nnano-emulsion obtained by the mixture design....
Chromium(VI) salts are possible contaminants of the chromium(III) pigments used as colorants in eyeshadow preparations. The\r\nuse of products containing these contaminants poses acute risks for sensitization and contact allergies. Chromium(VI) compounds\r\nare also classified as carcinogenic to humans (IARC group 1). An analytical method to analyse trace levels of chromium(VI) in\r\neyeshadow was developed in this study. The method is based on an extraction of the chromium(VI) from the sample using a\r\nmaximum extraction with alkali and additionally with synthetic lachrymal fluid to simulate physiological conditions. Following\r\nderivatization with 1,5-diphenylcarbazide, the extracted chromium(VI) is then quantified by spectrophotometry (540nm).\r\nValidation tests indicated a method standard deviation (inter- and intraday) of 8.7% and a linear range up to 25 mg/kg. The\r\naverage recovery was 107.9%, and the detection limit was 2.7 mg/kg. The applicability of the procedure was confirmed by the\r\nanalysis of pigments and authentic eyeshadow matrices....
