This study aimed to analyze a collection of Bcc isolates in PCPs and assess the susceptibility of preservatives, including dimethoxy dimethyl hydantoin (DMDMH), methylisothiazolinone-chloromethylisothiazolinone (MIT/cMIT), and methyl 4-hydroxybenzoate (MH). The Bcc isolates collected during the 3-year (2015-2017) study period were further examined by biochemical identification system, phylogenetic analysis based on recA nucleotide sequences, and multilocus sequence typing analysis. Preservatives susceptibility testing of Bcc bacteria were evaluated by minimum inhibitory concentration and minimum bactericidal concentration. A total of seven distinct sequence types (STs) were identified, which belonged to four different Bcc species: Burkholderia cenocepacia (ST621, ST258, and novel ST), Burkholderia lata (ST339 and ST336), Burkholderia contaminans (ST482), Burkholderia cepacia (ST922). For DMDMH and MH, the maximum permitted concentrations according to the safety specification of cosmetics (0.6% and 0.4%) were able to inhibit or kill all Bcc strains, but 40% of Bcc isolates could survive at higher than maximum permitted concentrations of MIT/cMIT (of a mixture in the ratio 3:1 of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one). The PCPs contamination of Bcc strains should be given more attention by manufacturers because of its diversity in molecular epidemiology and its low susceptibility to preservatives such as MIT/cMIT.","PeriodicalId":15523,"journal":{"name":"Journal of cosmetic science","volume":"71 3","pages":"133-148"},"PeriodicalIF":0.4,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38463808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It eliminates the need for physical shops such as nail salons. Nail art by 3D printing technology can achieve higher resolution and accuracy than before with conformal projection printing method (CPPM). The conventional method of painting nails manually leads to acute exposure to ultraviolet (UV) light that can contribute to minor health hazards. This research illustrates the benefits of using 3D printing for nail art. This study uses the IoT system, which can be stationed in a distinct location from the customer. The product on the nail is printed at least once and up to three times within 5 µm to achieve precise resolution through laser marking and CPPM, which can increase the accuracy by repeated projection to attain the required settling ratio. The correlation between the numbers of printed layers and different incident angles of the printing head on the conformal surface is discussed. The ratio of projected weight to the ideal weight for high-definition printing condition is illustrated, and comparison studies with conventional nail art techniques are conducted to validate the results.","PeriodicalId":15523,"journal":{"name":"Journal of cosmetic science","volume":"71 3","pages":"167-178"},"PeriodicalIF":0.4,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38463812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this study was to understand how the in vitro sun protection factor (SPF) and broad-spectrum protection of three organic UV filters (homosalate, ethylhexyl salicylate, and butyl methoxydibenzoylmethane) and a combination of these are influenced by solvents. Twenty-four solvents were selected based on the ingredient active gap for testing. Mixtures of UV filters and solvents were formulated, and in vitro SPF, wavelength of maximum absorbance, broad-spectrum protection, and spreadability were evaluated. Results indicate that in vitro SPF of organic sunscreens can be significantly enhanced by solvents. Relying on solubility data only was not found to be a good approach in this study. The most efficient solvents shared multiple similar structural characteristics, including ester bonds, conjugated structure, aromatic rings, and -CN groups; however, the absence of some of these structural elements did not necessarily prevent a solvent from being a booster. The wavelength of maximum absorbance was significantly shifted in the UVA range by most solvents, whereas minimal or no shift was observed in the UVB range. Results of this study provide practical information that can guide sunscreen formulators in selecting solvents for UV filters and making more effective sunscreens.","PeriodicalId":15523,"journal":{"name":"Journal of cosmetic science","volume":"71 3","pages":"149-165"},"PeriodicalIF":0.4,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38463809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentrate (up to 25 µg/ml) did not affect the proliferation of human fibroblasts. In addition, the concentrate significantly increased procollagen synthesis in the fibroblasts at 12.5 and 25 µg/ml; however, it significantly decreased the expression of matrix metalloproteinase (MMP)-1, MMP-2, and MMP-9 at 25 µg/ml. In a follow-up study, a wrinkle care cream containing 0.03% of fucoxanthin concentrate was prepared and tested in women (aged 35-50 years, n = 21) for 8 weeks. The cream was applied twice daily. Safety assessment of the cream was carried out visually. In addition, interviews were conducted to investigate if adverse events such as erythema, edema, scaling, itching, stinging, burning, tightness, or prickling had occurred. No symptoms that threaten skin safety were reported. Evaluation of wrinkles around the eyes using the replica method showed a statistically significant decrease in wrinkles at week 8. Moreover, skin moisture and elasticity increased significantly from week 4. These results suggest that the fucoxanthin concentrate has no adverse effects on the skin and can be used as an active ingredient in wrinkle care cosmetics.","PeriodicalId":15523,"journal":{"name":"Journal of cosmetic science","volume":"71 2","pages":"53-64"},"PeriodicalIF":0.4,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37818110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there are various available agents for treating acne, therapies for resistant or severe strains have been limited. The aim of this study was to investigate the inhibitory efficacy of ALACELL synthesized by combining 5-ALA with Y-G-G-F-L peptide against Staphylococcus aureus, Bacillus cereus, Escherichia coli, and Yersinia enterocolitica, as well as Cutibacterium acnes. Furthermore, other effects of ALACELL on human skin cells, melanin formation, intracellular tyrosinase activity, and Ultra Violet B (UVB)-irradiated cell death were measured by treatment of ALACELL in vitro. ALACELL particularly showed a growth inhibitory effect on C. acnes and no inhibitory effect on the four bacteria strains. ALACELL reduced melanin formation and intracellular tyrosinase activity by α-melanin cell-stimulating hormone (α-MSH) in B16F10 cells, with no cytotoxicity. ALACELL also improved cell viability in UVB-irradiated HaCaT cells. The results of the experiment show that ALACELL exhibits more efficacy than 5-ALA against antimicrobial activity, melanin formation, intracellular tyrosinase activity, and UVB-irradiated cell death. Therefore, ALACELL is recommended as a candidate for clinical application in the treatment of acne and skin aging and will be further investigated to study the mode of action and in actual situations.","PeriodicalId":15523,"journal":{"name":"Journal of cosmetic science","volume":"71 2","pages":"65-76"},"PeriodicalIF":0.4,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37818111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
