Oh please.
Aromatic hydrocarbons are in grilled meats and lots of other things you enjoy and eat on a daily basis. They do not inherently have a pleasant odor, many of them flat stink. Their toxicity varies tremendously and they frequently are not the most toxic compounds found in petroleum products.
That's too generic of a statement. Most drugs and medicines are aromatic hydrocarbons. A lot are over the counter, such as anesthetics (phenol). Mineral oil can be taken internally and it's a petroleum product, and then there's vaseline, baby oil (fragranced mineral oil)..
a) Aromatic hydrocarbons-
Are the most toxic compounds found in petroleum products, they have a pleasant odour and include such substances as naphthalene, xylene, toluene, and benzene. Most aromatic hydrocarbons are long-term toxins and known cancer causing agents, they are strong solvents and are used as a base for many useful compounds (i.e. engine degreaser, tar removers, etc) anywhere a strong solvent is required
a) Aliphatic hydrocarbons-
Include methane, propane, and kerosene. Aliphatic hydrocarbons are flammable and may be explosively flammable.
b) Naphthenic hydrocarbons-
After further distillation aliphatic produce Naphthenic hydrocarbonâ€â„¢s, these are used to produce light oils and as a base for light solvents adhesives and paint additives. Further purification produces Cyclo Paraffin and it is used in many pharmaceutical and skin beauty products. Cyclo Paraffin compounds are also used in car care waxes and polishes, used as a carrier system as they easily dissolve wax and provide spread ability and a lubricant for waxes, machine polishes and glazes.
c) Cyclo Paraffin hydrocarbon-
Are used in many car care products and perform many different and important functions. They are also used in many cleaning products as solvents to quickly emulsify oils, grease road tar and grime. They will not harm plastics, vinyl or rubber nor will they remove any important components like flex agents, plasticizers and etc, while it helps to clean and replace necessary oils to their surface.
