How to Dispose of Nitric Acid
In this article, we’ll address specifically how to dispose of nitric acid. Like most acids, nitric acid can be neutralized prior to disposal. This chemical reaction greatly reduces the hazardous risks of nitric acid, helping your business to comply with the three tenants of proper waste disposal. The reaction must be completed safely, which we’ll explain in this article.

Proper disposal of chemical reagents is essential for three reasons:
- Legal complianceWorker and environmental safety
- Minimizing business/laboratory expenses
- All labs and businesses working with hazardous chemicals must comply with the regulations set in place by OSHA (Occupational Safety and Health Administration) and local jurisdiction.
These regulations are in place to minimize risks to workers handling hazardous chemicals.Chemical waste disposal can be expensive for labs and businesses. Businesses must schedule waste pick-up from a hazardous waste disposal company. Minimizing your hazardous waste is one way to cut business costs. It will also reduce costs from replacing expired or spilled reagents.
Using 190 Proof Food Grade Ethanol To Make Perfume
High-Proof Food Grade Alcohol For Perfumes
Manufacturers use pure, high proof, alcohol in the production of perfumes. Professionals and hobbyists alike can use 190 proof food grade ethanol (95% alcohol) as a carrier, water, and essential oils to safely make alcohol-based perfumes with trademark scents. Proof is defined as twice the alcohol (ethanol) content by volume. Alcohol proof is a measure of the content of ethanol in an alcoholic product and is often used when describing beverages. Alcohol has three functions in perfume making and that is to safely apply the fragrance to the wearer, carry the scent, and dilute the fragrance. Since essential oils and fragrance ingredients can be harmful when applied to the skin, by diluting the concentration of the oils in the formula, it can be made safe for use. The type of carrier used in perfume formulations can affect the lasting power as well as the distance in which the scent can be detected. Since alcohol evaporates quickly, it can "carry" the fragrance with it. Lastly, since essential oils and other fragrance additives can be too pungent, alcohol serves as a diluent to enhance aromas. Alcohol-based perfumes are wonderfully fragrant liquids that are often manufactured by using essential oils that are extracted from flowers and spices. 190 proof food grade ethanol efficiently merge essential oils and aroma ingredients within the formulation. Many perfumers in the United States prepare herbs and flowers for making perfume.
Fragrances contain essential oils, but not all essential oils are appropriate as personal fragrances. Using food grade or organic ethanol in perfumes helps to impart a pleasant aroma to the body and clothes. Food grade ethanol and organic ethanol is also used to make skincare products.
Why 190 Proof Food Grade Ethanol Is Safer
Typically, perfume manufacturers buy specially denatured alcohol (SDA) to make perfume. This type of ethanol contains denaturing agents such as tert-butyl alcohol and denatonium benzoate, or commonly known as Bitrex. This denaturant is a bitter substance that is added to products to deter ingestion of toxic chemicals. According to the EPA's database on toxic substances, tert-butyl alcohol has a "camphor-like aroma" and is irritating to the skin and eyes. Additionally, ethanol is found in a variety of other household items such as cosmetics, foods, and mouthwash. As such, the FDA has labeled ethanol as GRAS (Generally Recognized as Safe). The formulations of SDA (Special Denatured Alcohol), approved by the TTB (The Alcohol and Tobacco Tax and Trade Bureau), for use in perfume manufacturing are listed here. 190 proof food grade ethanol is a solution of 95% ethyl alcohol and 5% water. Because high purity food grade ethanol does not contain toxic denaturing agents, it is safer to use than SDA ethanol in perfume making. Additionally, professionals and hobbyists should take into consideration the possible irritating effects of denatured agents on the skin, and how choosing the correct alcohol can affect the outcome of your final product. Since 190 proof food grade ethanol does not contain denaturants, it is taxed as a beverage alcohol, and as a result, is more expensive than denatured alcohol. However, when considering an alcohol that is safe for application on the skin, the cost difference is well worth it.
Types Of Perfume Ingredients Used With Ethanol
An important property that should be considered when formulating perfumes is how miscible or easily dissolved the solvents being mixed are with one another. Ethanol is a molecule that has both polar and nonpolar properties. Oils are completely nonpolar and water is a polar compound, thus they do not mix well. However, since water and alcohol are miscible due to their polar parts and alcohol and oil will mix due to their nonpolar parts, they are similar enough to not repel each other and mix evenly together. Popular ingredients used to formulate perfumes, enjoyable scents, essential oils, aroma oils, flavor oils and natural fragrance oils include 190 proof food grade ethanol, flowers, lavender, resins and jasmine.
Other natural ingredients used by perfumers include gums, oud, citrus, roots, balsams, grasses, cedarwood, leaves, patchouli, fruit, wood, sandalwood and amber. One thing to keep in mind when choosing a base oil is to ensure it is not toxic at high levels and the shelf life of your oil since some can go bad relatively quickly.
