Silica is an amorphous and nanometer scale voids and porous form of silicon dioxide. As long known for its high specific surface area synthetic silica has been used to adsorb water readily and applied for keeping many biological products dry protecting equipment from moisture damage. In the study the researchers have interested in making the tentative eco-friendly dehumidifying products based on the silica extract from bamboo leaves. The extraction procedures were performed by boiling dry bamboo leaves with various concentrated hydrochloric acid (HCl) at 1 2 3 and 4 M then burning them at 650oC for 4 hr before analyzing the purity of the biosilica with the X-ray Fluorescence Method. The results showed that the highest purity of the biosilica sample at 96% could be obtained after treated with 4 M HCl comparing with the control commercial silica. By hygroscopic test the extracted biosilica with 2 M HCl showed the highest moisture absorption properties close to the commercial silica. While the highest adsorption capacity was found in the biosilica sample treated with 3 M HCl. The dehumidifying efficiencies of all HCl treated biosilica power were not much different comparing to the commercial silica gel. Instead of using synthetic silica therefore this high environmentally friendly and cheaper biosilica from bamboo leaves can preferably be decent and further applied in green industry.

At present most human-related products contain a mixture of chemicals for inhibiting microorganisms polluting the environments and harming the users. The purpose of this research was to develop a product using banana and papaya peel extracts as replacers for the chemicals inhibiting microorganisms in heel cream. By extracting raw bananas and papaya peels with coconut oil the studying the efficacy of inhibition on E. coli S. aureus Aspergillus sp. and S. cerevisiae with Disk Diffusion method at the protein concentration were performed as follows: 25 50 100 and 150 micrograms per milliliter. The observation of clear zone to observer clear zone of inhibition. and the Turbidity method using light absorption at a length of 600 nm was also were shown the corresponding results of microbial inhibition. observed and showed the consistent results. Especially the papaya extract having the protein concentration at least of 150 micrograms per milliliter could inhibit all 4 microbe species but could not inhibit S. cerevisiae that indicated a good trend of no harm on human. When mixing the extract in the heel cream it was found that Heel cream containing banana extract papaya and both mixtures displayed the density of 0.9674 0.9103 and 0.8057 gram per cubic meter respectively. They could be stored at room temperature for more than 45 days and still maintained the properties of microbial inhibition by up to 80 percentages. When studying the satisfaction of consumers collected randomly from teenagers to elders at both sexes of 40 people more than 80 percentages of the customers were satisfied with the heel cream from all extracts. These all creams could make the feet soft and moisturized within 1 week. More suggestions were to improve the smell of heel cream products to be suitable for all age of consumers. Therefore this research could be concluded that banana and papaya peel extracts inhibiting microorganisms could be used as a heel cream for further continuously developing at the industrial level.
