Rubbing alcohol is not suitable for ingestion, and drinking it could be harmful, so Clove
Rubbing alcohol, USP / Surgical spirit, B.P. is a liquid prepared and used primarily for topical application. It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropyl alcohol (isopropanol). Individual manufacturers can use their own "formulation standards" in which the ethanol content usually ranges from 70-99% v/v. In Ireland and the UK, the equivalent skin preparation is surgical spirit, which is always an ethyl alcohol-isopropyl alcohol mixture. It is colorless. The melting point is -89 °C. The boiling point is 82.5 °C.
The term "rubbing alcohol" has become a general non-specific term for either isopropyl alcohol (isopropanol) or ethyl alcohol (ethanol) rubbing-alcohol products. Health
A hand sanitizer or hand antiseptic is a supplement or alternative to hand washing with soap and water. Various preparations are available, including gel, foam, and liquid solutions. The active ingredient in hand sanitizers may be isopropanol, ethanol, n-propanol, or povidone-iodine. Inactive ingredients in alcohol rubs typically include a thickening agent such as polyacrylic acid for alcohol gels, humectants such as glycerin for liquid rubs, propylene glycol, and essential oils of plants. Alcohol based hand sanitizers are more effective at killing microorganisms than soaps and do not dry out hands as much.
Common non-alcohol, rinse-free hand sanitizers use either small concentrations of the nitrogenous cationic surface-acting agent benzalkonium chloride, the chlorinated aromatic compound triclosan, or povidone-iodine. Some products claim to kill microorganisms naturally, although these claims are not substantiated in any FDA monograph. All hand sanitizer products require National Drug Code designation in United States and natural product number designation in Canada.]citation needed[ Antiseptics
Persia was a cradle of science in earlier times. Persia contributed to the current understanding of nature, medicine, mathematics, and philosophy. Persians made important contributions to algebra and chemistry, invented the wind-power machine, and the first distillation of alcohol. Trying to revive the golden time of Persian science, Iran's scientists cautiously reach out to the world. Many individual Iranian scientists, along with the Iranian Academy of Medical Sciences and Academy of Sciences of Iran, are involved in this revival.
Iran is an example of a country that has made considerable advances through education and training, despite international sanctions in almost all aspects of research during the past 30 years. Iran's university population swelled from 100,000 in 1979 to 2 million in 2006. 70% of its science and engineering students are women. Iran's scientific progress is reported to be the fastest in the world. Iran has made great strides in different sectors, including aerospace, nuclear science, medical development, as well as stem cell and cloning research. Chemistry
