The SA had improved flowability and water resistance compared with non-modified arrowroot flour (A0), concurring with the Fourier Transform Infrared (FTIR), scanning electron microscope (SEM) analyses that indicated more hydrophobic properties. To investigate the formulated dust and compressed powder, three types of binders including magnesium stearate (Ms), isopropyl myristate (Im), and mineral oil (Mo) were examined. Powder samples of all binders at each concentration gave high water resistance with floating time of more than 15 min and high compressibility at 37.88% ± 0.91% to 42.59% ± 0.28% Carr’s index value and 1.61 ± 0.02 for the Hausner ratio. The hardness was 72.53 g ± 3.25 g to 98.00 g ± 3.78 g and drop test results differed depending on the density and adhesion properties of each formulation. The color stability was acceptable and not statistically significantly different when using different binders. Microbiological analysis of total bacteria count, yeast and mold in the silicone-arrowroot modified starch and pressed powder were <10 CFU∙g–1, while non fecal coliform, fecal coliform, Candida albicans, Staphylococcus aureus, and Clostridium spp. were not found.","PeriodicalId":502897,"journal":{"name":"Journal of Metals, Materials and Minerals","volume":"673 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140482752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process begins with the preparation of a high-concentration masterbatch of LLDPE with nucleating agents and polyethylene glycol (PEG), followed by blown film and test analysis. The results showed that both single and hybrid nucleating agents resulted in substantial modifications in the surface characteristics of the film. The altered surface texture of the film makes fat stains easy to remove. In addition, the use of hybrid nucleating agents resulted in considerable roughness on the film's surface. It can calculate the average roughness (Ra) from atomic force microscopy (AFM) images, which is very low at 4.7 nm, and the roughness is consistent. The contact angle was 99.17 degrees, and the percentage of crystallinity was clearly higher than that of a single nucleating agent. As a result, the fat stains on the film surface are easier to remove. The visual appearance, morphology, functional group, and mechanical properties of the films, on the other hand, were not significantly different. In summary, using a nucleating agent helped to rinse fat stains from the film easily.","PeriodicalId":502897,"journal":{"name":"Journal of Metals, Materials and Minerals","volume":"19 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
