“…Also, this cream could enhance the water-holding capacity of the skin of 19 female subjects with an average age of 27±6 years over a 3-day duration. 9 More importantly, no skin erythema formation and inflammation was observed for this cream. Similarly, Wagemaker et al 39 conducted an animal experiment by irradiation of hairless mice smeared with green coffee oil cream and reported that the SPF of green coffee oil cream was proportional to the coffee oil content.…”

“…4 For instance, Velazquez Pereda et al 8 reported that following treatment with green coffee oil (3.12-25.0 mg/mL), both human derma fibroblast cell CC-2511 and human skin keratin cell HaCaT could induce the formation of collagen, elastin, and glycosaminoglycans by 1.8-, 1.5-, and 2-fold, respectively. In another study dealing with the preparation of emulsion with coffee oil as raw materials, Wagemaker et al 9 illustrated that coffee oil was efficient in treating skin damage caused by ultraviolet B (UVB; 280-320 nm) radiation, with the sun protection factor (SPF) being 1.5. Moreover, following the emulsion smearing onto human skin, both the trans-epidermal water loss (TEWL) and erythema index showed a declined trend, demonstrating the light protective effect of coffee oil.…”

“…In another study, Wagemaker et al 5 further pointed out that the SPF of coffee oil extracted from C. arabica green coffee waste was about 1.5 as it could absorb UVB irradiation. In recent two studies, Wagemaker et al 9,39 prepared a cream composed of green coffee oil, cetearyl alcohol, ceteareth-20, glycerol, methyldibromo glutaronitrile, and butylated hydroxytoluene. Following the treatment of HaCaT cells with cream (10-100 µg/mL) for 24 h, the cell viability was .100%, implying that this cream did not show toxicity toward HaCaT cells.…”

Coffee grounds, a waste by-product generated after making coffee, contains approximately 15% coffee oil which can be used as a raw material in cosmetics. Algae oil rich in docosahexaenoic acid (DHA) has been demonstrated to possess anticancer and anti-inflammation functions. The objectives of this study were to develop a gas chromatography-mass spectrometry (GC-MS) method for the determination of fatty acids in coffee oil and algae oil and prepare a nanoemulsion for studying its inhibition effect on ultraviolet A-induced skin damage in mice and growth of melanoma cells B16-F10. A total of 8 and 5 fatty acids were separated and quantified in coffee oil and algae oil by GC-MS, respectively, with linoleic acid (39.8%) dominating in the former and DHA (33.9%) in the latter. A nanoemulsion with a particle size of 30 nm, zeta potential −72.72 mV, and DHA encapsulation efficiency 100% was prepared by using coffee oil, algae oil, surfactant (20% Span 80 and 80% Tween 80), and deionized water. Differential scanning calorimetry (DSC) analysis revealed a high stability of nanoemulsion when heated up to 110°C at a pH 6, whereas no significant changes in particle size distribution and pH occurred over a 90-day storage period at 4°C. Animal experiments showed that a dose of 0.1% coffee oil-algae oil nanoemulsion was effective in mitigating trans-epidermal water loss, skin erythema, melanin formation, and subcutaneous blood flow. Cytotoxicity test implied effective inhibition of melanoma cell growth by nanoemulsion with an IC 50 value of 26.5 µg/mL and the cell cycle arrested at G2/M phase. A dose-dependent upregulation of p53, p21, cyclin B, and cyclin A expressions and downregulation of CDK1 and CDK2 occurred. Also, both Bax and cytochrome c expressions were upregulated and bcl-2 expression downregulated, accompanied by a rise in caspase-3, caspase-8, and caspase-9 activities for apoptosis execution. Collectively, the apoptosis pathway of melanoma cells B16-F10 may involve both mitochondria and death receptor.

247 Biomedical and Biopharmaceutical Research J o r n a l d e I n v e s t i g a ç ã o B i o m é d i c a e B i o f a r m a c ê u t i c aRheology, clinical efficacy and sensorial of a silicone-based formulation containing pearl extract Reologia, eficácia AbstractIn traditional Chinese medicine, pearl extract is believed to nourish skin and prevent the aging process. Thus, the aim of this study was to evaluate rheological characteristics, immediate effects on skin, and sensory properties of a silicone-based cosmetic formulation containing pearl extract. Formulations containing pearl extract or not were submitted to physical stability assays by determinations of its rheological behavior during 28 days storage. Once confirmed the formulation's stability, they were applied on the volar forearm of 15 healthy female to evaluate skin properties by non-invasive techniques. After a single application, formulations increased the stratum corneum water content. Once applied on the volar forearm for sensory analysis, the volunteer's majority noted that both formulations improved all the sensory skin attributes, but only the pearl extract formulation has shown the higher scores for all attributes. Results suggested that the silicone-based formulation supplemented with the pearl extract could combine unique sensory properties and effectiveness to better meet consumer's demand. Keywords: Silicone, Pearl Extract, Rheological Behavior, Biophysical Techniques, Sensory AnalysisResumo Na medicina tradicional chinesa, acredita-se que o extracto de pérola pode nutrir a pele e prevenir o processo de envelhecimento. Assim, o objectivo deste estudo foi avaliar as características reológicas, os efeitos imediatos sobre a pele e as propriedades sensoriais de uma formulação cosmética à base de silicone contendo extracto de pérola. As formulações contendo extrato de pérola ou não foram foram submetidas a ensaios de estabilidade física por determinação do comportamento reológico durante 28 dias de armazenamento. Uma vez que as formulações se mostraram estáveis, elas foram aplicadas na região interna do antebraço de 15 indivíduos saudáveis do sexo feminino para avaliar as condições da pele usando técnicas não-invasivas. Após uma única aplicação, as formulações aumentaram o conteúdo de água do estrato córneo. Quando as formulações foram aplicadas no antebraço para a análise sensorial, a maioria dos voluntários notaram que ambas as formulações melhoraram todos os atributos sensoriais da pele, mas que apenas a formulação com extrato de pérola mostrou as maiores notas para todos eles. Os resultados sugerem que a formulação à base de silicone adicionada de extracto de pérolas pode combinar propriedades sensoriais únicas e eficácia para melhor atender a demanda dos consumidores.Palavras-chave: Silicone, Extracto de pérola, Comportamento reológico, Técnicas de biofísica, Análise Sensorial.
