Contact allergens
Ethanol is widely used for its solvent and antiseptic properties. It is rather an irritant and sensitization has rarely been reported.
LogP -0.19
ethyl alcohol (Etanol) is commonly known as rubbing alcohol. ethyl alcohol is ordinary alcohol and is used medicinally as a topical antiseptic, astringent, and anti-bacterial. At concentrations above 15 percent, it is also a broad-spectrum preservative against bacteria and fungi, and can boost the efficacy of other preservatives in a formulation. Cosmetic companies tend to use alcohol SD-40 in high-grade cosmetic manufacturing as they consider ethanol too strong and too drying for application on the skin. obtained from grain distillation, it can also be synthetically manufactured.

storage Ethyl alcohol should be protected from physical damage. It should be kept stored in a cool, dry, well-ventilated location, away from any area where the fi re hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfer to avoid static sparks. The storage and use areas should be free from smoking areas.
Precautions During handling of ethyl alcohol, workers should use chemical-resistant shields, monogoggles, proper gloves, laboratory coat/apron, and protective equipment as required. Workers and the workplace should have adequate ventilation vent hoods, class b extinguisher. Workers should avoid sources of heat, sparks, or flames. Waste disposal and spill should be collected in suitable containers or absorbed on a suitable absorbent material for subsequent disposal. Waste material should be disposed of in an approved incinerator or in a designated landfi ll site, in compliance with all federal, provincial, and local government regulations.
Safety Profile
Confirmed human carcinogen for ingestion of beverage alcohol. Experimental tumorigenic and teratogenic data. Moderately toxic to humans by ingestion. Moderately toxic experimentally by intravenous and intraperitoneal routes. Mildly toxic by inhalation and skin contact. Human systemic effects by ingestion and subcutaneous routes: sleep disorders, hallucinations, dtstorted perceptions, convulsions, motor activity changes, ataxia, coma, antipsychotic,headache, pulmonary changes, alteration in gastric secretion, nausea or vomiting, other gastrointestinal changes, menstrual cycle changes, and body temperature decrease. Can also cause glandular effects in humans. Human reproductive effects by ingestion, intravenous, and intrauterine routes: changes in female fertility index. Effects on newborn include: changes in Apgar score, neonatal measures or effects, and drug dependence. Experimental reproductive effects. Human mutation data reported. An eye and skin irritant. The systemic effect of ethanol differs from that of methanol. Ethanol is rapidly oxidtzed in the body to carbon dtoxide and water, and, in contrast to methanol, no cumulative effect occurs. Though ethanol possesses narcotic properties, concentrations sufficient to produce this effect are not reached in industry. Concentrations below 1000 pprn usually produce no signs of intoxication. Exposure to concentrations over 1000 pprn may cause headache, irritation of the eyes, nose, and throat, and, if continued for an hour, drowsiness and lassitude, loss of appetite, and inability to concentrate. There is no concrete evidence that repeated exposure to ethanol vapor results in cirrhosis of the liver. Ingestion of large doses can cause alcohol poisoning. Repeated ingestions can lead to alcoholism. It is a central nervous system depressant.Flammable liquid when exposed to heat or flame; can react vigorously with oxidizers. To fight fire, use alcohol foam, CO2, dry chemical. Explosive reaction with the oxidized coating around potassium metal. Ignites and then explodes on contact with acetic anhydride + sodum hydrogen sulfate. Reacts violently with acetyl bromide (evolves hydrogen bromide), dichloromethane + sulfuric acid + nitrate or nitrite, disulfuryl difluoride, tetrachlorosilane + water, and strong oxidants. Ignites on contact with disulfuric acid + nitric acid, phosphorus(IⅡ) oxide, platinum, potassium tert-butoxide + acids. Forms explosive products in reaction with ammonia + silver nitrate (forms silver nitride and silver fulminate), magnesium perchlorate (forms ethyl perchlorate), nitric acid + silver (forms silver fulminate), silver nitrate (forms ethyl nitrate), silverp) oxide + ammonia or hydrazine (forms silver nitride and silver fulminate), sodum (evolves hydrogen gas).
